Change camera ( ). This button appears only if your computer

has cameras on both the front and the back—a common
arrangement on tablets. (The back camera is for photography; the
front camera is for video chats.) Each time you tap this button,

your view switches to the other camera.

Zoom ( ). If the slider isn’t there, click the magnifying-glass
icon to make it appear. It’s generally a digital zoom, meaning that
it works by enlarging the picture, degrading the quality.

HDR ( ). In one regard, digital cameras are still pathetic:
Compared with the human eye, they have terrible dynamic range.
That’s the range from the brightest to darkest spots in a single

scene. If you photograph someone standing in front of a bright
window, you’ll get just a solid-black silhouette. The camera
doesn’t have enough dynamic range to handle both the bright

background and the person standing in front of it.

A partial solution: HDR (high dynamic range) photography. That’s
when the camera takes three (or even more) photos—one each at

dark, medium, and light exposure settings. Its software combines
the best parts of all three, bringing details to both the shadows and
the highlights. If you see this button, then your machine has a

built-in feature that attempts to build an HDR shot automatically.
This is the on/off switch.

Self timer ( ). Yes, kids, your machine has a self-timer. It works
in both photo and video modes. It’s great for getting a self-portrait
or a self-video when you don’t want to be right at the machine.

Tap this button once for a drop-down menu that offers two-, five-,
or ten-second countdowns. Now when you hit the button, “3…
2…1” countdown digits appear—and then the photo gets snapped,

or the video begins.
