Hands On With Samsung's Dual-Display Cameras
There is no lower form of photography than the arm-out self-portrait, but we all do it. To
their credit, Samsung's TL220 and TL225 make shooting your Facebook profile shot
a littleeasier.
Ignoring the screen for a second, the TL22x cameras are a decent get for the price, with
720p video recording, haptic touchscreens (though the interface isn't terribly intuitive or
responsive), and a full range of expected features for a midrange point and shoot. The only
noticeable differences between the TL220 and TL225, which will ship at $299 and $349,
respectively, are the 225's aluminum body, larger screen and HDMI output. But anyway, the
screen's the thing people are curious about here, so here you go:

As you can see, it's there. When the camera is off, you can't see it—it goes black, and sits
flush and invisible against an equally black camera face, at least on the test unit I saw. You
turn it on with a direct tap of the finger, which I repeatedly had trouble getting to register,
though I was told that was due to preproduction hardware iffyness. I'll trust Sammy on this
one, but a simple toggle button would've done fine here.
The screen isn't just for self-shooting, although it manages that just fine. It'll also show
playful images to get childrens' and/or idiots' attention. (In the case of the default clown
animation, "playful" means "disconcerting," a fact which isn't helped by how difficult it is to
navigate the menus to make him go away. ) No worries though: You'll be able to download
more animations from Samsung's website, apparently.
Another simple function is a countdown timer, which gives you a numerical countdown to
timed shots, letting you and your photomates know exactly when to mug.
At any rate, your first intuition on this was probably correct: front-facing LCDs are somewhat
gimmicky, but they do what they say, making life easier for the internet-popular
or extremely lonely. The catch would've been that the feature prices the cameras out of
mainstream accessibility, but it doesn't. So hey, why not? (This, I think, was Samsung's
design mantra here) [Samsung]
