Digital cameras: Digital imaging - gamma adjustment
Digital imaging - gamma adjustment
by rgfitz - 1/13/05 6:13 PMIrfan View 3.95
I was trying some settings using this free software with a digital photo taken in a hot humid environment with my camera partially fogged, inside and out.
By chance I tried Image > Enhance Colors > Gamma Correction. Decreasing the Gamma setting completely "erased" the fogginess and enhanced the colors.
I can't believe the difference!
A quick Google search didn't yield much information on Gamma other than:

Thanks, but

I noticed the National Geographic Field Guide - Digital, uses a term "Curves" for a digital image adjustment tool that may do the same thing as "Gamma". "Curves" may be a Photoshop tool but I really don't know.
