That's what I used to do Rinze!! But it's not as good as Rich's method! His method is more precise and keep all the details of the pics on top of the luminosity. If u scroll up to #18, I explained that: "I have to thx u for the conversion method here Rich! I tried both urs and mine (which was to just completely desaturate the image) and I've noticed that a few details where lost when doing it my way while ur method preserved all that was there! Fabulous and SO simple!" Hehe! ;)
