I used Photoshop/GIMP to improve the mid-tones of pictures. However, I don’t have access to Photoshop anymore and want to use Irfanview to do the same thing. The Gamma value (1 to 7) does brighten the image well.
Lately I have been learning that, all along when I used brightness/ contrast slider, it was the wrong way to do good adjustment.
My questions:
1. How does gamma value improve midtones in Photoshop/GIMP?
2. What does gamma value mean exactly?
3. With respect to curves, how does the Gamma value relate to the curvature of the curves?
4. Is doing gamma value one of the good ways of improving an image?
Thanks.
