how to use basic camera control on your smartphone
Here are some pointers that apply to all Android phone Camera apps:
Use the phone in either landscape or portrait orientation while taking a still short. Don’t worry either way: The image is always saved with the proper side up.
I strongly recommend that you record video in horizontal orientation only. This presentation appears more natural.
The phone’s touchscreen serves as the viewfinder; what you see on the screen is exactly what appears in the final photo or video.
Tap the screen to focus on a specific object. You see a focus ring or square that confirms how the camera lens is focusing. Not every phone’s camera hardware can focus: the front-facing camera features a fixed focus.
Zoom in by spreading your fingers on the screen.
Zoom out by pinching your fingers on the screen.
Some phones let you use the Volume key to zoom in or out: Up volume zooms in, Down volume zooms out. If the Volume key doesn’t zoom, it may serve as a second shutter button (to snap the picture). While you’re shooting video, the Volume key may serve to snap a still shot.
Hold the phone steady! I recommend using two hands for taking a still shot and shooting video.
The phone stores pictures and videos in the DCIM/Camera folder. Still images are stored in the JPEG or PNG file format: video is stored in the MPEG-4 format. If your phone offers removable storage, the Camera app automatically saves images and videos to that media.
