I have been trying to make my own color and B&W presets for Lightroom lately. I have used VSCO presets (namely Fuji 160C for color and Ilford HP5 for B&W) as starting points and tweaked them to my liking. I have some kind of a B&W period going on now and finding a nice preset for B&W is a very important thing to me. The two presets I have now made are just starting points to me but I am able to get close to a final presentation with a one click using them. Usually I make minor adjustments after applying my presets though.
