Photo or Art?
I just purchased a piece of Plug-in software for my Photoshop CS5 editing software. It NIK Software's Silver Effects Pro 2 for B&W conversion. It takes your opened photo and gives you over 30 variation in black & white and sepia. It's incredibly easy to use and produces dramatic results in seconds. So fare I've been able to quickly eliminate all but 5 and then compare one-on-one until I get a winner. The whole process takes about 2 minutes to make up my mind.
