Donald Trump's old house is being sold for $54 million, according to listing agent Tamar Lurie.

The impressive mansion is nearly 20,000 square feet with eight bedrooms, 13 bathrooms, a putting green, home theater, tennis courts, and three staff apartments.

It sits on 5.8-acres and was built in 1939. Donald and Ivana Trump bought it in 1982 for $4 million, and Ivana refurbished it with the same materials she was using to redo the Plaza Hotel in Manhattan at the time, according to Top Ten Real Estate Deals.

When the pair divorced n 1991, Ivana got the mansion and sold it seven years later for $15 million. In 2000, the new owners renovated the home and added the tennis courts, additional guest rooms, as well as an indoor lap pool.

Even without the tennis courts, it must have made quite the charming starter mansion. The current owners, who wish to remain anonymous, have listed the home with Coldwell Banker agent Tamar Lurie.

Welcome to Donald Trump's old Connecticut mansion. The Georgian Colonial-style home was built in 1939.

It sits on 5.8 acres of land. Donald and Ivana bought the home in 1982 for $4 million.

It's on a peninsula so it has ample views of Long Island Sound in Indian Harbor.

Family cars, like families themselves, come in all shapes and sizes. But regardless of which brand or type of car families are looking for, the focus is on vehicles with a great combination of safety, reliability, feature content, and space. U.S. News and World Report evaluated 259 different cars using those exact criteria and found 19 winners — each representing a segment of the market.

"Family cars don’t need to be dowdy or boring,"  U.S. News Best Cars managing editor Jamie Page Deaton said. "The 2015 Best Cars for Families help parents identify great cars with features that keep everyone in the family happy, such as roomy cabins, infotainment systems, separate temperature controls and tools for keeping teen drivers safe." 

Nine separate brands took home awards. General Motors grabbed four, while Toyota won three. Honda and Kia each won twice. 

Compact Cars: Volkswagen Golf

Upscale Small Cars: Mercedes-Benz C-Class

Hatchbacks: Kia Soul

York Castle Museum specialises in displays of ordinary life in York's streets and houses from the 1700s onward, to give visitors an idea of what it was like living in Northern England generations ago.

The exhibits progress through the Victorian era, with all its filth and squalor loving detailed (there's even a foul, pre-running-water outdoor privy). Mannequins wear flat caps. Everything seems to be made of leather, sack cloth and wax.

And then visitors are confronted by something that both delights and horrifies in equal measure: "The 1980s Kitchen."

It is exactly what you think it is. An exact replica of a typical suburban British kitchen from 1981. Visitors burst out laughing as they wonder why their parents' house deserves to be in a museum. Then it dawns on them that 1981 was over three decades ago — in the last century. 

It turns out that everything in the exhibit was acquired by the museum in about 1982. "The provenance for these objects is the same, they were all donated or purchased in the 1980s specifically for this display, says collections facilitator Dr. M. Faye Prior. 

It was originally called "The 1981 Kitchen" and was installed in 1982 "as a comparison to the adjacent '1940s Kitchen' display, showing how kitchens changed in the 20th century," according to Prior. 

Prior says, "1980s Kitchen" was "carefully designed to reflect the kind of brand-new fitted kitchen people were buying in 1981. Its pine picnic-style table and benches were very popular, as were the fitted units with integrated cooker and washing machine."

People remember the '80s as a very "modern" era but these empty milk bottles show how old-fashioned it was at the same time: People still had their milk delivered daily by the local dairy.

A glass jar with tricolour spaghetti and a cork stopper: "Pasta was still quite a novelty in the early 1980s," says Prior.

Microwave ovens were new in the 1980s. Note how small the window is. This one, a Sanyo, comes with a cookery book — consumers who had only ever used gas or electric stoves needed to be taught how to cook in a microwave.

"Everything in the room is a museum object with the exception of the cereal in the bowls on the table (we also use reproduction food in our seasonal displays)," Prior says.

"The brown plastic washing up bowl, drainer and brush are almost the same as those we have today, but the colour is very much of the early 1980s."

This "Autumn Leaves" tea service came in "a fashionable beige with a bulbous design and bramble pattern."

This Vax vacuum cleaner was the Dyson of its day — the trendiest, most up-to-date vacuum you could buy in 1981.

"1980s Kitchen" disappeared from the museum for several years. "It was redisplayed in 2002, and receives a makeover every Christmas when we decorate it with 1980s cards and tinsel, and with seasonal party food," Prior says.

"1980s Kitchen" was originally curated by Stephen Harrison, then Keeper of Folk Life at the museum. He aimed to show visitors that "folk life," or social history, "isn't just a study of the distant past, it’s about the everyday lives of regular people."

Kirsty Bertarelli is Britain's richest woman. And as a multi-billionaire she lives an enviably incredible life.

Her fortune is so vast that it eclipses Harry Potter author J.K. Rowling and the Queen combined, at £9.75 billion ($14.5 billion), according to the Sunday Times Rich List 2014.

She became Miss UK as a teenager, an accomplished music writer in her 20s, and then in her 30s became the wife and the mother of three children with Switzerland's richest man, Ernesto Bertarelli, who sold his family's pharmaceuticals firm Serono for £9 billion to Merck in 2007.

Now in her 40s, she is trying to take the world by storm with her singing. She has already supported Simply Red's Mick Hucknall in concert and performed for the Prince and Princess of Monaco.

Through interviews from The Telegraph,the Mirror and from her website, as well as pictures from her Instagram, we've put together the fairytale that is Kirsty Bertarelli's life.

Kirsty Bertarelli, née Roper, was born and raised in Stone, Staffordshire on June 30, 1971.

But her tale isn't a "rags to riches" story. Her father, along with her uncles, owned one of the world’s largest manufacturers of ceramics, Churchill China.

She even went to the now defunct private boarding school Howell’s in North Wales, and gained seven O levels.

“Curry” as we know it is an Americanized-knock off of Indian food.

What we think of as “curry” are dishes that have been cooked with curry powder, typically with pre-mixed flavors of turmeric, ginger, chillies, and coriander, among others.

But these dishes would be almost unrecognizable in India, which uses much more diverse blends of spices (masalas) in its dishes, all individually prepared and added as you cook so that the mixture is unique and varying depending on the region and sometimes by specific kitchen.

Put simply, “curry” is a massive oversimplification of Indian cuisine.  

We can thank the British for what we think of as “curry.” They coined the term back when Imperialism was still strong, and it most likely stems from the dish “kari,” which is a type of spicy gravy Indian dish with sauce ladled over meats. For example, “Kozhi Kari” roughly translates as chicken with gravy.

But in India, not all “karis” are called “kari.” 

“In North India, the rich, sauce-heavy dishes we might call 'curries' go by many different names,” Laura Siciliano-Rosen, the co-founder of Eat Your World, explained to Business Insider. “Butter chicken, kadhai paneer, mutton korma, saag chicken, and so on.”

And each of these dishes will have a unique blend of spices and bold flavors all their own. Plus, Siciliano-Rosen added that while Americans often add rice to soak up the space in their curry, in India it’s much more common to use bread, especially roti or chapoti.

So if you want to try and make authentic Indian kari, a few of the key spices to have on hand are turmeric, garam masala, cumin seeds, coriander power, cinnamon, red chili or cayenne powder, cardamom, ginger, garlic, and mustard seeds. Don’t be afraid to branch out and experiment. 

And if you want to order authentically Indian dishes the next time you’re at a restaurant, stick to dishes without “curry” in the name and look for palak paneer, saag chicken, or mutton korma. Order a side of roti and dip it in your extra sauce.

That doesn’t mean you can’t use your curry powder when you’re cooking — it’s delicious in salad dressings and some soups — just realize that it’s not an authentic part of Indian cuisine.

NOW WATCH: Watch 2 armed gangs fight on a busy road in China

So, Neill Blomkamp’s Chappie opened in theaters, and by the look of it, it appears to be a mix and match of Short Circuit, RoboCop, E.T., A.I., District 9, and a Die Antwoord music video.

But one thing seems sure: It will be yet another demonstration of the movies’ fascination with robots.

Ever since the early years of cinema — even before the term “robot” was coined, in fact — the movies have been obsessed with them. They symbolize so many of our neuroses — our queasiness about technology and the unknown, our wonder at what it means to be human, our fear that, ultimately, we might be replaceable.

So, we thought it might be fun, in honor of Chappie (or as a corrective to it . . . you decide), to rank the best robot movies in film history. However, a note: We specifically focused on movies that are essentially about robots — not, in other words, movies that happen to have robots in them, like Alien(s) or Interstellar or Forbidden Planet. We also avoided films that were specifically solely about computers — so, no 2001: A Space Odyssey. (But The Matrix makes it in, because it’s actually full of robot creatures.) And, as always, only one film per franchise.

15. "Robots" (2005)

This star-studded animated flick (Ewan McGregor! Robin Williams! Mel Brooks!) wasn’t particularly well-liked when it first came out, but it’s enchanting and beautiful.

Set in a world populated entirely by robots (like Cars, but with robots), it’s filled with elaborate contraptions and eye-popping visuals, with an aesthetic that seems to have been borrowed from every era of futuristic design imaginable. You could lose yourself in it for hours.

14. "Transformers" (2007)

Okay, forget how much you hated the sequels for a second. Michael Bay’s first Transformers movie was actually pretty fun — a peculiar mix of broad humor, badass fighting-robot heroics, apocalyptic CGI, and the director’s patented military fetishism.

Let’s also not forget that the idea of a big budget Hollywood movie based on a 1980s toy franchise — especially one as ridiculous as this one, which posits an alien race of robots that have come to Earth and assumed the ability to turn into everyday vehicles and other machines — was by no means a surefire hit. And yet, Bay pulled it off. Bloat and self-importance would eventually consume the franchise, but this first one still holds up. 

13. "Big Hero 6" (2014)

Disney’s blockbuster animated film from last year was surprisingly dark; it was, ultimately, a movie about how different people cope with loss. And at the heart of it was a sensitive relationship between its young orphan hero and Baymax, the cuddly, puffy medical droid created by his late brother. As the boy tried to teach the gentle Baymax to fight, we got a heartfelt exploration of the limits of grief and the value of helping those in need.

If you're in Austin for the big SXSW tech and music trade show, you may be wondering where you can grab some grub in between panels and parties.

From classic Texas BBQ to some out-of-this-world tacos, there's plenty of great food in Austin. 

Inspired by lists created by Zagat and Foursquare, we've compiled a list of the restaurants you should check out during SXSW. 

The Salt Lick

18300 FM 1826, Driftwood

3350 Palm Valley Boulevard, Round Rock

3600 Presidential Boulevard, Austin-Bergstrom International Airport

You can't go to Texas without getting BBQ, and the Salt Lick is arguably one of the most fun places to do it. Residents and visitors to Austin are crazy about their brisket and ribs, and it's all cooked on the most insane pit you'll ever see. The original location is about 20 miles outside of Austin, in Driftwood, in addition to locations in Round Rock and the airport.  

Chuy's

1728 Barton Springs Road

1050 North Lamar Boulevard

4301 W William Cannon Drive

This classic Tex-Mex chain is "always a good time," according to Zagat reviewers. It's known for its generous portions and strong drinks.

Uchi

801 South Lamar Boulevard

This may not be your typical Austin cuisine, but it's a treat nonetheless. Zagat gave this longtime sushi favorite top marks in food quality and popularity with residents. The sushi dishes are inventive and unique, like a foie gras nigiri and tuna sashimi made with goat cheese. 

Over the course of five generations, the Bush and Walker clans have amassed fortunes and political power beyond belief. The family is worth a reported $60 million and has seated two members in the Oval Office.

With former Florida governor Jeb Bush, son of George H.W. Bush and younger brother of George W. Bush, as a GOP front-runner for the 2016 presidential election, we're looking back at how his family came to earn such influence.

This retrospective includes insights from Jacob Weisberg's exhaustive biography, "The Bush Tragedy" and more, as well as vintage photos.

Check out our visual guide on the Bush-Walker family lineage »

Samuel Prescott Bush, son of a minister, lay the foundation for the family’s fortune. Known as the grand patriarch of the Bush clan, he was an Ohio steel and railroad executive.

He worked his way up from an apprenticeship to become president of Buckeye Steel Castings Co., the country's third largest producer of steel couplers at the turn of the century. Samuel rubbed elbows with the Rockefellers and cofounded the U.S. Chamber of Commerce.

Samuel had a son who wanted nothing to do with his father’s manufacturing ventures. He would carve his own success story.

When asked what is the best pillow to use, Dr. Jan Lefkowitz of Body in Balance Chiropractic did not say memory foam, down, or synthetic.

In fact, he said a pillow most people have never heard before — Chiroflow.

“You fill it up with water and it has different recommended amounts so that you can customize it for how big you are,” he explained to Business Insider. “It looks like a regular foam pillow but then you fill it with water, your head displaces the water and it fills the curve of your neck perfectly.”

Dr. Lefkowitz insisted he wasn’t trying to shill for the company — he said you can buy Chiroflow on Amazon and he gets no profits from talking about it. 

He just says it’s that good.

The Chiroflow has been around for 20 years since the inventor Maurice Bard suffered a whiplash injury. His chiropractor told him to place a “waterbag” under his pillow to give him cervical support and alignment, and Bard realized he could create a pillow with a similar structure for other neck injury sufferers.

His final design features a top layer of polyester that feels like a standard pillow with a compartment that you fill with tap water. You can adjust the support level to soft, medium, or firm by adding or removing water. Once you have your optimum level, you don’t need to change the water for an entire year.  

“The water chamber is enclosed by a therma-shield to prevent any heat transference from the your head to the water chamber and visa-versa," Nick Ortega, the sales and marketing manager for Chiroflow, explained to Business Insider. “This prevents the likelihood of mold or any other bacteria to grow within the water chamber.”

Dr. Lefkowitz isn’t the only one backing up Chiroflow. It has become the top selling chiropractic pillow and was even peer reviewed in a clinical study in 1997 by the Johns Hopkins University School of Medicine, which found that it reduces neck pain and improves quality of sleep.

From the study, which was in the “Official Journal of the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation”:

The water-based pillow was associated with reduced morning pain intensity, increased pain relief, and improved quality of sleep. The duration of sleep was significantly shorter for the roll pillow. Overall SIP findings showed a significant advantage for the waterbeds pillow over the roll pillow and standard pillow.

Amazon reviews are also astoundingly positive, with the majority of reviewers saying it’s been the only pillow to help their necks and that it helps them sleep better than any other pillow. 

The reason Chiroflow is beloved by chiropractors is because its design allows your head to displace the water and fill up the space between your neck and the mattress, thus keeping you spine aligned — a very important design function, according to Dr. Lefkowitz.

“The main idea is you have to keep your spine parallel and neutral,” he told us. “From head to toe, you need to be in a straight line.” 

The pillow also self-adjusts throughout the night so that sleepers don’t continually wake up to readjust their pillow, leading to better nights of sleep.

So if you’re like almost half of the American population that’s not getting enough sleep, perhaps it’s time to try a new pillow.

They call it "shockvertising" — ads made to shock their way into your memory by way of gruesome violence, over-the-top sexuality, or other taboo-shredding imagery. 

Ad agencies around the world have adopted the audacious method, with activist organizations like PETA specializing in scandalous imagery. 

Italian clothing retailer Benetton pioneered the style in the 1980s. Its now-iconic campaigns have received mixed reviews, like an award-winning AIDS awareness ad from 1991 that showed a father holding the lifeless body of his son in a hospital bed.

The style is powerful, but it can backfire, like when the World Wildlife Fund drew ire for comparing the 2004 Tsunami disaster to the World Trade Center attack. 

We took print images from the past few decades to give you a look into the global shockvertising scene. It's up to you to decide if they're brilliant, offensive, or both.

There are more influential females in the advertising industry than ever before. Female creative directors account for around 11% of ad industry award-winners, up from fewer than 4% a decade ago.

But while there have been improvements, women are still seriously under-represented in the industry. That's why each year we put out a call for entries for our annual rankings for the most creative women in Adland. 

From these nominations, paired with our own research, we selected 30 amazing women. Factors we considered included recognition within the industry, seniority in their respective agencies, size of the shop, and stand-out creative work that's garnered attention outside of the advertising world.

Our list is by no means complete. But it does feature the fiercest talents in the business.

Later this month, Apple will join the Dow Jones Industrial Average.

Apple will replace AT&T, which was better-known as American Telephone & Telegraph when it originally joined the Dow in October 1916.

This 30-stock index has seen a lot of turnover in its history. And believe it or not, there were only 12 stocks in it when it was created in 1896.

"The Dow Jones Industrial Average consisted entirely of industrial stocks, as it was published for the first time," noted S&P's Howard Silverblatt. It's a lot more diverse today.

And only one of the original 12 members continues to hold a spot in it.

American Cotton Oil

What it did: It formed as a trust after several mill owners in Texas and Arkansas combined syndicates to regulate the price of seeds. It became a corporation in 1889 after the trust was dissolved through a lawsuit.

Where it is now: It evolved into a company that's now part of Unilever. The original company was dropped from the Dow in 1901.

Sources: Scripophily, Wikipedia

American Sugar Company

What it did: It was the largest American company in the sugar refining business in the early 20th century, with investments in the Caribbean. It was established in 1891 with $50 million in capital. 

Where it is now: It has since been acquired by American Sugar Refining, whose products include Domino Sugar. It was dropped from the Dow in 1930.

American Tobacco Company

What it did: The American Tobacco Company acquired over 200 competitors to become the dominant player in the industry. It was founded in 1890.

Where it is now: The Supreme Court ordered it to dissolve following an anti-trust lawsuit. It splintered into many smaller companies and renamed itself Fortune Brands. It was dropped from the Dow in 1985.

Vladimir Putin may be the wild card in world affairs right now, but he didn't gain that influence overnight.

The Russian President's ascension to power is filled with spies, armed conflicts, oligarchs, oil and (of course) judo.

So here's how a onetime "nobody" climbed up the ranks to become the "World's Most Powerful Person."

Vladimir Putin was born in Leningrad on Oct. 7, 1952.

Vladimir Vladimirovich Putin is the only child of a decorated war veteran and factory worker in the slums of Leningrad. He grew up in a Soviet Union styled communal apartment with two other families — as was typical at the time.

Source: Encyclopedia, TIME

As a teen Putin worked at his school's radio station, where he reportedly played music by the Beatles and other Western rock bands.

The photographer Platon — who took Putin's infamous Time Magazine cover in 2007 — said that Paul is Putin's favorite Beatle, and "Yesterday" is his favorite song.

However, "by [Putin's] own account, his favorite songs are Soviet standards, not Western rock. He has been deeply conservative his whole life," Karen Dawisha wrote in her new book, "Putin's Kleptocracy." 

Source: Encyclopedia

Early on in life, Putin got into judo. He was his university's judo champion in 1974.

Former deputy finance minister and first deputy chairman of the Central Bank Sergey Alaksashenko believes that Putin's love of judo says something about his foreign policy.

"Unlike chess, a judo fighter should not wait for the opponent's move. His strategy is to wait until he gets a chance to execute a single quick move — and then take a step back. Successful judo fighters must anticipate their opponents' actions, make a decisive, preemptive move and try to disable them," he wrote in the Moscow Times.

The problem with the 18k gold Apple Watch Edition isn't that $10,000 is a lot for a watch. It isn't. 

It is, however a lot for a first generation gadget.

Once you get into the $10,000 range in watch buying, you start buying for investment. These are the watches that become family heirlooms: timepieces that are kept forever, worn on special occasions, and eventually passed down to children.

It's virtually guaranteed your children are not going to want a first generation Apple Watch. In fact, in only a few short years the Apple Watch Edition will probably only be as valuable as the metals that can be salvaged after melting it down

Luxury watch brands, on the other hand, have been making mechanical movements and gorgeous watch cases for centuries.

Their intricate movements and insanely strong pedigree helps them maintain their value. And the best part is: the technology never changes.

Here are just a few smart purchases for those in the market for an investment-grade watch.

IWC Portugieser Automatic IW5007

The Portugieser is one of IWC's most popular models. With its legendary Pellaton winding system and select ceramic components, this watch is sure to hold its value.

Suggested Retail: $13,700

Rolex Datejust

Rolex is probably the most recognized watch brand in the world. This means that everyone knows how great the Datejust is — and everyone wants one.

Suggested Retail: $12,750

Jaeger-LeCoultre Master Memovox

Jaeger-LeCoultre is a watch name that needs no introduction. It's been making spectacular watches with insanely precise movements since 1833 and the elegantly designed Master Memovox continues that tradition.

Suggested Retail: $11,100

We recently pitted the iPhone 6 camera against the DSLR Canon 5D Mark II and the point-and-shoot Canon PowerShot SD1400-IS. The iPhone held its own in many areas, and it's unbeatable when it comes to portability.

And as the adage goes, "The best camera is the one you have with you."

But for those of us who make a living taking photos or count photography as a serious hobby, the camera phone will never replace a DSLR (digital single-lens reflex).

Here are my reasons why:

Interchangeable lenses

The biggest difference between a smartphone camera and a dedicated camera is the ability to use different lenses.

The importance of good glass cannot be understated. High-quality lenses produce unparalleled sharpness and image quality. These photos look crisp, detailed, styled, and hyper-real. They look like photographs instead of snapshots.

In addition, a professional or "prosumer" camera allows you to use whatever lens is appropriate for the situation. If you are shooting sports, you can put on a zoom lens to get close to the action. If you are taking a portrait of someone, you can use a short telephoto lens. If you want to capture a crazy party, put on a wide-angle lens to get the entire scene. You get the idea.

The striking photo below, for instance, was taken from more than 50 feet away with a Nikon D90 and a 300-mm telephoto lens. An iPhone attempting the same photo would never have been able to zoom that closely without pixelating the entire image.

In addition, portraits simply look better with a DSLR and a lens designed to flatter people. The iPhone is stuck using its default, slightly wide-angle lens, which isn't flattering on people.

That’s just the utility aspect. If you want to get into the craft and artistry of photography, using different lens is one of the foremost ways to produce different, interesting images.

There are external lens attachments that you can add onto your iPhone, like the Olloclip 4-in-1 iPhone Lens System, the iPro Lens Kit, and iZZi Orbit Pro. These are an improvement over the default lens in the iPhone, but the quality cannot compare with a DSLR lens.

In general, the materials in external smartphone lenses are not high quality. It's hard to expect them to be. The most expensive of these external lenses ranges between $200 and $300. The lowest-end DSLR lenses start around there.

In addition, many of the iPhone lenses have issues with vignetting (when a photo darkens or blurs near the edges), sharpness, distortion, or are just plain clunky.

Ergonomics

A smartphone will always beat a professional camera for portability. It’s built to travel in your pocket everywhere, and it's easy whip out at just the right time. It’s sleek. It’s cool. It fits nicely in your hand. One thing it’s not built for? Taking photos.

Think about every time you’ve ever taken a photo on an iPhone. Sure, it's only a couple of clicks to the camera app and snapping the photo, but think about the actual feel of it in your hands and how hard it is to frame an interesting photo.

It’s awkward. You have to hold the phone out in front of you. You have to look on a small screen to see how everything fits. Even on a large phone like the iPhone 6 Plus or a Galaxy S, it’s difficult to see whether all of the elements in your photo are composed exactly the way you want or if you’ve captured the delicate focus you are looking for. It’s hard to take photos in a crowded setting and not have everyone around you know exactly what you are taking photos of.

Compare that to just about any dedicated camera. It’s made for the explicit purpose of shooting photos. It sits in your hands nicely, easily allows you to adjust settings without fumbling with the back of the screen, and the camera responds tactilely to the press of the shutter.

Best of all, there’s a viewfinder. You can look through the viewfinder and see exactly what your photo looks like at the size you are looking at, not through the prism of a smartphone screen. Composing small details and framing is easier, more accurate, and more precise.

Manual settings

The iPhone, like almost all smartphones, is hopelessly lost in this category. The iPhone’s default Camera app, which most people use, offers no way to manually adjust settings.

Here's why that's a big problem.

All cameras, including the iPhone and my Canon DSLR, are pretty dumb when it comes to determining proper exposure in all but ideal situations. Imagine a black-and-white photo. All cameras’ automatic sensors want to turn everything in your photo into a dull, even gray. Shooting snow? Gray. Shooting jet-black asphalt? Gray. All photographers know this, and it's why every good photographer uses manual settings to compensate.

Now the iPhone does have manual settings, so long as you download an app like Manual or Snapseed. These are helpful and bring the smartphone closer to what I'm looking for in a camera, but ultimately they are mere approximations to what a true camera does. The shutter speeds and ISOs that smartphone cameras can handle — two out of three factors when determining proper exposure — are so limited that most of the time you are better off just letting the auto settings on the camera do its thing.

Further, smartphone cameras have lenses with a fixed aperture (the hole in the lens through which light passes). Being able to change your aperture is important because it allows you to do all sorts of stylistic things that make photos look great. Shooting a mountain landscape? Adjust your aperture so that it is very small and everything from the mountains to the field in front will be in focus. Doing a close-up of a flower? Adjust to a wide-open aperture, and you can make sure the camera focuses only on the flower, while the whole background turns into an aesthetically pleasing blur.

Here's what a close-up photo looks like with a Canon 5D Mark II and 35-mm lens:

And the iPhone 6:

Notice anything?

First, the iPhone has predictably turned our white bowl gray in all but the brightest areas. Second, the bright orange of the carrots has lost some of its luster. The photo is exposed and focused well, but overall it's boring.

Take a second look at the DSLR photo. The exposure settings have been adjusted manually to make sure the bowl stays bright white. Doing so also pitched up the colors of the carrots and jalapenos, making a more aesthetically pleasing shot. Finally, by using a sharp 35-mm lens and a large aperture, I created a visually interesting focal plane that draws the eye in. And that's in a shot that took me all of a minute to set up.

Manual settings are also hugely important when shooting motion. Depending on the lighting in the situation, shooting motion (like sports and moving cars) is one of the most difficult photographic situations there is. It requires constantly tweaking your settings in minute ways to trick your camera into giving you the best it can. In all but bright and sunny conditions, smartphone cameras just don’t measure up. Adjusting settings on the fly is clumsy and autofocus is too slow and imprecise. In addition, smartphone cameras simply can’t handle the high shutter speeds necessary for capturing motion. It’s a recipe for bad photos.

Sensor size

One of the biggest determinants in digital image quality is size of the image sensor in your camera. When it comes to that, smartphones simply can't measure up.

Digital camera sensors are full of millions of light-sensitive spots that record information about what is seen through the lens. The bigger the sensor, the more area for the camera to capture and record light. (In the old film days, the equivalent was the size of your film: A large-format camera that took 8-by-10 film always took far more detailed photos than those taken by a 35-mm camera.)

How big is the difference between sensor sizes? Look at this graphic (note that even though Apple introduced a new sensor with the iPhone 6, it’s still the same size as earlier models):

Cameras with larger sensors are capable of capturing more information, producing photos that have more contrast, more accurate colors, and less noise, especially when shooting in low-light situations.

Ever try shooting in a dark room with an iPhone? The photos are barely passable. There’s blur and noise if you're lucky, and ugly flash if you're not.

Here's a photo I took with my iPhone at a Jack White concert earlier this year:


Here's a photo taken by a DSLR on Getty Images. It was taken last year at Governor's Ball in New York City. White was using roughly the same stage and lighting set-up.

Leaving aside the fact that the DSLR was able to get much closer with a telephoto lens, the most obvious difference is the detail in White's skin tone and clothes. While the DSLR was able to turn a difficult lighting situation into a compelling photo, the iPhone struggled to capture even the largest details. The band members' skin is too bright and everything else is too dark.

The problem is equally pronounced in bright situations. Here are two photos I took of identical street scenes. The first is with the DSLR, the second with the iPhone 6.

While both have some issues with lens glare and contrast — a hallmark of shooting in the middle of the day — the iPhone's issues are more pronounced. The DSLR retains detail in the brightest parts of the image without blacking out all of the shadows. The iPhone 6 image, on the other hand, has extreme lens glare, almost no detail in the shadows, and bright light clouding most of the image.

Leaving aside lighting issues, larger sensors produce higher-resolution photos, which means that when you want to blow up the photo on your 80-inch plasma TV or print them out to hang on your wall, they still look sharp.

Ever tried to print out a photo taken on your iPhone? They generally look awful. I’ve had plenty of friends try to show me prints of iPhone photos, and I’ve had to lie more than a few times that their photos "look great."

Now some of you will probably say, Pssh. Just give Apple/Samsung/HTC some time. They’ll make a bigger sensor. Chances are they won’t. Consider the form factor of a smartphone and just how much other stuff they have to pack into that ever-slimming frame. They may increase the sensor marginally, but it will never match a dedicated camera.

The verdict

All of this isn’t to say that an iPhone, Samsung Galaxy S, or other smartphones aren’t fine cameras. They are. Ultimately, the quality of photos comes down to skill level of the person taking them.

Hand an amateur an 8-by-10 large-format camera and they won’t know what to do with it. Alternately, give a skilled photographer an iPhone and they can produce awesome, awe-inspiring work. (If you want to see some amazing iPhone work, check out the book Hashtag Sandy.)

But give me a choice, and I would always pick my DSLR.
