Digital Cameras With Room for New Views

Katherine Boehret — Tue, 06 Oct 2009 23:36:02 +0000

At a glance, the most obvious physical improvements on today’s digital cameras compared with those bought five years ago are slimmer size and larger LCD viewing screens. Other than that, they don’t look a whole lot different.

But this week, I tested two physical features that I’ve never seen on digital cameras.

[ See post to watch video ]

I used the $430 Nikon Coolpix S1000pj (nikonusa.com), which has a mini projector built right into the camera itself. This extra characteristic lets you take pictures and, by pressing a button on the camera, project them onto any nearby surface, in old-school slideshow style. The projected image can measure up to 40 inches, growing or shrinking as you walk away from or toward the surface onto which the images are projected.

I also tried the $350 Samsung DualView TL225, which had two LCD viewing screens—including one on the front side. This front screen lets the subjects of the photograph see how they look as the photo is being captured, raising the concept of instant gratification to a new level. The outward-facing LCD can also display a smiley face or cartoon animations to encourage children to smile. It also can be used to display a timer’s countdown clock so you know exactly when the photo will be taken.

Technical Advances

These two compact cameras also feature less obvious technical advances that aren’t quite as eye-catching as a built-in projector or dual LCD screens.

Each camera can capture photographs with over 12-megapixel resolutions, and the Nikon and Samsung have 5x and 4.6x wide-angle zoom lenses, respectively.

Both cameras have built-in automatic scene-detecting capability, meaning they can analyze a scene to determine which shooting mode would work best. And they allow the user to edit images directly on the camera like brightening an image or rotating a photo.

The Nikon sticks to one traditional 2.7-inch LCD screen with separate buttons that control functions like menu, timer, deleting and playback. And, like many digicams, it accepts a SecureDigital (SD) memory card.

Getting your good side: Samsung’s DualView TL225’s front LCD shows people how they’ll look in photos.

In somewhat unusual fashion, the Samsung requires a tiny microSD memory card. The viewing screen on the back of the Samsung is a generous 3.5-inch touch LCD that covers close to an entire side of the camera; the front-side LCD is 1.5 inches.

I focused my testing on the unique physical features of each camera: the Nikon’s built-in projector and the Samsung’s two LCD screens. I tried them out over the course of a week and used them in real-life situations including at a birthday party and at the Army 10-Miler, an annual run in Washington, D.C.

When the Nikon’s projector isn’t in use, it functions like a regular camera—albeit an expensive one at $430. Nikon says this price is largely due to the cost of its built-in projector. Until now, most people who wanted portable, mini projectors bought them as standalone products; for example, the Pico Pocket Projector from Optoma Technology Inc. is listed for $230 online at Best Buy (BBY).

Subway Show

I took the Nikon Coolpix S1000pj along to the Army 10-Miler, capturing photos of runners as they ran near the National Mall. Later on, while I waited with hundreds of people to get on the D.C. Metro subway system, a friend and I looked through photos from the day by projecting the camera’s images onto a concrete wall.

At first, passersby thought the slideshow images were put there by the race organizers, and they commented about how neat it was that the race images already were posted for everyone to see.

The D.C. Metro was an ideal spot to use the Nikon’s projector because of its low light and white concrete walls. Outdoors, the projected images weren’t quite as easy to see.

I also used the projector in a house and in my office, setting it on a table and turning off the lights for the best view. A tiny remote comes with the camera if you want to sit back and give your friends and family a slideshow. Videos taken with the camera also will play in video format.

To start the projector, I pressed a button on the top ledge of the camera, which immediately covered the lens and turned on the projector’s bright light. A slider button adjusts focus. The image size can be as small as five inches and as large as 40 inches, and it will project from about six feet away. Nikon says the camera’s projector will work for an hour before its battery runs out.

Nikon’s S1000pj displays images and videos with its brightly lit projector—just right for a subway slideshow.

Surprise, Surprise

The $350 Samsung DualView TL225 is black with an accent color that comes in purple or orange. Its front-side LCD screen isn’t visible when the camera is turned off, making for a surprising experience when you take pictures of friends who can suddenly see themselves.

A similar but slightly lower-quality and less-expensive version of this camera is available in the $300 Samsung DualView TL220. This camera’s back LCD screen is a half-inch smaller than the TL225’s and not nearly as bright. Other notable differences include the TL220’s plastic casing compared with the TL225’s aluminum.

Clowns in Action

This front LCD performs various functions in addition to showing people what they look like. A scene called Children puts animated cartoon clowns on the outer LCD in hopes of making a child smile for the camera. Another setting puts a large, yellow smiley face on this LCD when the shutter button is pressed down halfway. And when the camera’s timer is set, the outer display counts down, showing “3, 2, 1″ until the image is captured.

I used this Samsung camera with two LCD screens to take pictures of friends who were all surprised and delighted when they saw themselves on the camera before the photo was taken. At a birthday party, the clown animations made even a group of people in their 20s laugh.

Some Downsides

The downside to this display screen is that it’s to the left of the camera’s lens, so if you’re taking a close-up shot of someone, they will appear in the photo like they’re glancing away slightly.

Another negative of this display is that it blacks out a split second before the photo is taken, so as long as you can hold the pose you saw of yourself on the screen, you’ll look fine.

It’s too early to know whether the innovations in these cameras will catch on, or be viewed over time as expensive gimmicks.

If these features become more common, hopefully the prices will come down and more consumers will be able to enjoy them.

Digital Cameras That Do Thinking for You

Katherine Boehret — Wed, 23 Apr 2008 00:01:00 +0000

Most digital cameras have more settings than the average person knows what to do with — from common adjustments for nighttime and face shots to obscure settings for sports, fireworks and snow scenes.

When the moment comes to take the perfect picture of a snowy mountaintop, Fourth of July fireworks or soccer goal in midkick, most people forget about these features or don’t know how to use them. And while many digital cameras can now detect faces and make sure they are in focus, they can’t tell whether that face is smiling or not. The results aren’t bad, but they could be much better.

Sony’s Cyber-shot DSC-W170 uses Smile Shutter Mode to snap pictures when a subject smiles.

This week, I tested three new digital cameras that claim to do the thinking for you. Some digitally analyze the scene you’re about to capture, automatically choosing the setting that would take the best picture. Others can detect when a subject is smiling so as to automatically know when to snap the photo. One camera even attempts to digitally alter frowning faces into smiles, with amusing results.

I tried out Sony’s $300 Cyber-shot DSC-W170, Kodak’s $250 EasyShare Z1085 IS and Olympus’s $200 FE-340. Only the Sony (SNE) includes all three of the aforementioned features; the Kodak (EK) has scene detection, and the Olympus (OCPNF.PK) camera has built-in smile detection. I found the automatic scene detection offered in the Sony and Kodak cameras to be the most useful feature for everyday photos. It improved my photos and didn’t require any extra adjustments. I handed the cameras to other people to take pictures, without having to change any settings.

The automatic smile detection offered in the Sony and Olympus cameras was fun to use and could be especially helpful for families whose young kids never seem to smile at the right moment. But it didn’t work consistently and had trouble detecting my bearded boss’s smile and even that of a beard-free colleague.

I found Sony’s frown-fixing tool, which is called Happy Face Retouch, to be rather unusual. It took already captured images of my friends’ faces and turned their frowns or ambivalent looks into smiles, but didn’t adjust the subjects’ eyes. Though this was good for laughs, the eerie-looking grins pasted on faces reminded me of painted-on clowns’ mouths. And some attempts to retouch a face couldn’t detect the face to alter it. But a handful of the Happy Face Retouches looked somewhat natural.

Similar Specs

These cameras boast many similar specifications. All three use 5x optical zoom lenses, and the Sony Cyber-shot DSC-W170 and Kodak EasyShare Z1085 IS each have 10.1 and 10 megapixel image sensors while the least expensive Olympus FE-340 has 8 megapixels. The Sony and Olympus both have generous 2.7-inch viewing screens and almost identically sleek builds, though the Sony is the only one of these three cameras to have an optical viewfinder.

The Kodak’s viewing screen is slightly smaller than the other two digital cameras, measuring 2.5 inches, but its build isn’t nearly as compact as the others. It reminded me more of small, high-end SLR camera, with its comfortably large hand grip, a settings knob on the top edge of the camera, and a protruding zoom lens.

Sony’s Happy Face Retouch feature digitally changes facial expressions into smiles, but all it did was make me look unnatural and awkward.

Kodak’s EasyShare Z1085 IS takes Secure Digital (SD) memory cards, which are more common than the Memory Stick and xD cards that work in the Sony and Olympus cameras, respectively.

The Kodak and Sony digital cameras have different names for their automatic scene-detection features. By default, the Kodak camera works in Smart Capture Mode, which includes intelligent scene detection, capture control and image processing. I focused on the camera’s scene detection, which automatically determines whether the photo should be taken in Macro, Text (for shots of text in a book, for example), Face, Landscape or Night settings.

Icon on the Screen

I snapped pictures around Washington, D.C., noting a tiny icon on the camera’s screen that indicated which of the five scene modes was being used to capture the photo. A flower icon indicating Macro appeared on my screen when I stooped to get a close-up shot of a tulip, and an icon of a dark sky and stars showed on the screen when I took photos at night. The camera’s flash, focus and exposure changed according to the type of photo.

The Sony camera uses what it calls Intelligent Scene Recognition to decide which settings should go along with certain photos. Like the Kodak, icons on the Sony’s screen indicated the scene settings that were automatically deemed appropriate, including Backlight, Backlight Portrait, Twilight, Twilight Portrait and Twilight Using a Tripod.

The Sony’s Intelligent Scene Recognition isn’t on by default like Kodak’s feature. Instead, it must be turned on from within a menu, but once on, it stays on until you turn it off. ISR can be used in either Auto or Advanced mode; Auto takes a single photo with automatically determined settings, while Advanced takes two shots — one with manual settings you can choose and another shot immediately following the first with automatic settings according to what the camera thinks is best.

I experienced surprising results with the Sony Cyber-shot DSC-W170 and Olympus FE-340 while testing their automatic smile-detecting functions. My friends thought I was joking when I told them the camera would take their picture only if they were smiling. When the flash went off multiple times as they kept smiling, they were intrigued by this feature.

Sony’s version, which it calls Smile Shutter Mode, is easy to switch into by turning a dial on the camera to a smiley face. Once this setting is chosen and the camera’s shutter button is pressed, the Cyber-shot will search for smiles in its subjects, and will take photos whenever it detects a smile. Settings within this mode can be set to specifically detect an adult’s smile or a child’s smile, and the degree of smile can be set to low, medium or high; I kept things simple by leaving the smile detector on default settings.

Capturing Smiles

Olympus calls this feature Smile Shot, capturing three rapid shots in a row to make sure everyone’s smiling. The idea of taking three shots would be extra helpful with an indecisive baby, but most of my friends were able to hold their smiles, which produced three almost exactly identical shots each time someone smiled. Smile Shot is harder to get to in a pinch compared with the Sony: it’s buried in a list of 13 settings on the Olympus when the camera is set in Scene mode.

The Olympus seemed to be a bit slower than the Sony when it came to detecting smiles, but both had trouble with bearded men and even some folks without beards. And people felt silly standing around with a smile on their faces waiting for the camera to finally work. Closed-mouth, no-teeth smiles were harder for these cameras to detect, but not impossible. In group situations, the Olympus camera will focus on whoever’s face appears largest, which could mean the person closest to the camera, while the Sony takes a picture whenever anyone in the group smiles.

Putting a Happy Face On

If someone isn’t smiling, Sony’s Happy Face Retouch tool can come in handy, but don’t count on liking the results. In a group shot of five friends, two people who weren’t smiling put a bit of a damper on the whole shot. I used Happy Face Retouch, but it picked up on only one of the nonsmiling faces, turning a confused look into a smile that looked passable. But other results weren’t usable. A serious-looking shot of me deliberately not smiling looked freakishly unnatural after the touch-up, mostly because the rest of my face didn’t join the smile. I looked more like someone who had received too many Botox treatments.

Sony says that, in group shots, it can detect and change up to eight faces, but in my tests it usually changed only one. This retouching tool is also difficult to find: It took me 16 button presses to change each image into a smile — or what Sony calls a smile. A few times, Happy Face Retouch couldn’t identify a face in the photo, even when just one person stood in the frame.

These digital cameras took good photos, overall, and are fun to use because they take pressure off the photographer. I found the automatic scene-detection tools of the Kodak and Sony to be the most realistic and useful offerings, and I’m sure it won’t be long before automatic scene detection becomes as commonplace as an automatic flash.
