I have a kodak point a shoot camera. I know very little except but i have a question that maybe someone can answer. Seems like when i take pictures indoors there is a tint to them.
If it is an orange tint, the reason is incandescent lights.
Does your P&S give you a menu option to change the White Balance setting? (it may be abbreviated as WB) If you are able to change it, don't forget to change it back to Daylight or to Auto. Otherwise, when you go outside, your shots will be tinted blue.
If you can't change it, a levels adjustment layer will probably make the correction. Don't simply move the slider when it "opens on RGB". Click the drop-down box next to the word "Channel" and adjust the Blue, Green and Red channels individually. (there was a Kimi Homework assignment on this -- don't remember the number).
An alternative to individual channel adjustments, if you have something in the image that's supposed to be white, is to use the white eyedropper. That may do the trick.
