Choosing the right digital camera
4. Special functions
Some digital cameras do more than just taking pictures. Here are some of the more interesting features we're seeing in cameras today:
Video recording
Some cameras have a video recording mode that lets you record short video clips. These movie clips are not very fluid, as the cameras capture only about 15 frames per second, whereas normal video captures and plays back 30 fps. They also take up an enormous amount of storage space. It may be an interesting gimmick, but video capability should not be a reason for choosing one camera over another.
Audio recording
Many cameras let you record a few seconds of audio to accompany each photo. It's also good for picking up ambient sounds. Say, for example, you took a picture of a loved one at the beach. The sound of crashing waves on the shore can add depth to an otherwise stagnant picture.
MP3 audio playback
Recently, more manufacturers are beginning to produce cameras that can play MP3s uploaded from the PC. This may be popular with teenagers, but we don't see it having widespread appeal since the devices tend to cost more, and the camera performance can be compromised.
