Jeremy, I just received issue #4 of Color Magazine. You can see a copy of the cover at
http://www.color-mag.com/. This is a special issue showing the winners of their recent portfolio contest. As I paged through the magazine I was struck by the idea that you should have had a group of pictures you're showing on this thread in there. I had sent in a portfolio, but after looking at the pictures that won prizes I realize I'm way, way behind the times in color work. I'm still doing representational photography, and that's not what's getting a boost these days. I'd almost be willing to bet that a collection of the kind of thing you're showing in this thread would have made it into the magazine. Your pictures here are fine examples of what they were looking for.
They're now starting their annual single-picture contest. You might think about entering one or more of the pictures in this thread. It'll cost you $25 and a bit of preparation, but if you're interested in showing your work, think about it.
Oh well... You can't teach an old dog new tricks, but at least I have an ad in this issue.
