I am sure that I am one of the last ones to ever use this, but I just came across it today. Under the enhance tab, convert to black and white. I have never used that before. I have always just desaturated and adjusted highlights and shadows to my liking. I don't know anything about these sliders so maybe someone could enlighten me. I chose infrared on this photo and then just adjusted my sliders until I thought it looked good. I have never used this before so be gentle. I don't even know what infrared is but I am reading about it as soon as this posts. Thoughts and Advice?
