As you might know, there are a bunch of photo communities out there, most of which aren’t worth mentioning (unless you’re interested in seing lots of rave reviews of bad photos of nakes women). altphoto.com is the notable exception. There are some remarkable photographer who show their work there, incl. some who you’ve already seen here (for example JP Zorn). Just look around a little, and you can discover gems such as the photographer who calls himself drFeelgood (who Mark Tucker pointed out to me).
