[arvinkg]

hi..I am using Hoya R72 and Nikon D300..I am shooting RAW and then I set custom white balance on grass using eyedroper, but...after chanell mixing as explained here...I always get yelow grass...not white...or almost white when I shoot in JPEG using preset white balance on grass..

on this first page of my photostream..you can see mu IR photos....where I make mistake?

Try playing with curves on the blue channel. I always do that for me to get yellow foliage for an autumn effect but you can do the "S" curve as well to control the yellow foliage and make it less yellow.

If the grass is yellow you can either desaturate it to make it white or saturate it more to give it bolder colors. Experiment with moving around the sliders on your channel mixer and see what you like.
