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

Thanks Cathy

Many fans of Canon's G-series cameras have complained about the
long overdue release of a new version. Some have suggested that
Canon is phasing out the line. But a couple of days ago someone
posted a link to a commercial European website (Italian, IIRC) that
had a brief mention of a G7. If you have no immediate need, it
might be worth waiting a month or two to see if Canon really has a
G7 in the works, or if this was just a red herring.

As for White Balance, you don't normally set it for every shot.
You change it when the type of light you're shooting in changes.
You have several choices. Either set it to Auto WB and the camera
tries to make an educated guess, or you manually set the WB to match
the existing lighting. Some cameras have few options, some have
many. These might include Bright Sun, Overcast, Incandescent
Lighting, several fluorescent (such as Warm White, Cool White and
Daylight), and a custom WB that you set manually using a white or
gray card. More experienced photographers shoot in RAW mode, which
is more flexible, as the WB is assigned using photo software,
*after* the shot has been made, which avoids the occasional
disasters when photographers might accidentally shoot dozens or
hundreds of shots using the wrong white balance. The G6 has 7
preset WB settings, including 2 custom manual WB settings and also
allows you to shoot either RAW or JPEG files.
