Hi
I am thinking of buying a canon G6 camera and was wondering about the
different photo formats and in what kind of situations you would use
each. I was reading about White balance do you set that for each photo.
Thanks Cathy

To a large extent, which one you use depends on what you wish to do with the
images:

RAW - lossless compression of the output of the sensor. Quick to download
Requires plugin for your photo editor and your camera. Most flexible
editing
JPEG - lossy compression results in small image size. A little slower to
download because the camera must demosaic the image and then compress.
Useful for email and web sites
TIFF - lossless or no compression. A little slower to download because
camera must demosaic the image. Useful if you decide the image needs lots
of editing

White balance - No, instead you set the white balance for every kind of
ambient light.
