I don't know DxO but usually you can introduce multiple control points on the curve. Is this a magic bullet? No, probably not, but it is a useful tool if your picture is too dark or too bright and you don't want to blow the Blacks or Highlights.ĭisclaimer! I probably haven't understood this yet, so if you know more please fill in!Ĭlick to expand.Most of my processing consists of cropping, the black and white point adjustments you mention, and more general bending of the tone curve than just a gamma correction. So I tried raising the Gamma a a bit and it worked as well, for this picture I upped the Vibrancy and Saturation to get clearer colours. So that is what I usually do, lower the Gamma for all channels.īut recently I had a too dark picture (PPC543) after getting the White and Black points were I wanted. What I have observed is that lowering the Gamma gives more "pop" to the picture, almost like if you up the Vibrancy and Saturation. If I raise the Gamma (Still all channels, RGB) the picture will be brighter without changing the Black point or the White point, you bend the curve! Same for lowering the curve, darker picture without changing Black point or White point! Let me explain by example, first I try to get the White and Black points were I want them, usually without any clipping in either Black or Highlight, this might give me a too bright or too dark picture, so that is were Gamma comes in. (As I learn more I might apply it to individual channels but for now it is all of them.) What I mean by changing the Gamma is to all channels, RGB. In DxO PL there is a Tone Curve (probably there is one all programs), it defaults to RGB but the individual Red, Green and Blue channels can also be used. What do I mean by Gamma correction or changing the Gamma? A question, are any of you using the Gamma control regularly?
