Hello! I just wanted to say thanks for the tutorial. I found it in my search and gave it a shot while processing a recent image. I put the image up for critique, so can't share it here. But if you're interested in checkin it out, here's the link.
Thanks!!
PS: kc10360 - I had the same issue at first, but solved it by selecting gradient options that have four colors, then just changed the colors of the four sliders based on the recommended values (double click slider and type in the exact color number at the bottom). Hope that helps!
