how to use colors(as in change colors, reduce color etc) , lighting , contrast in the images? i did not find any tut on this hence asking here.
also please tell how to blend images?
on the tab at the top select Color then scroll down to Colorize (That gives you the option to change the colour completely), Levels (Which can change the colour as well), Desaturate (Which reduce colors) or Brightness-Contrast.
I know a loonnngggggg time has passed since you have asked this but still posting a tut by Zenron if you or anybody else will be still searching for it.
