You asked about Abstract, Portrait, and Fine Art photographers on G+. Here's my Abstract Photographers circle. I'm sure it's not complete, but it is growing. I'd love to know of others you have found that might fit the circle.
And, as always, you can find lots of good folks (1,000 now) in the Abstract Photography Community here on G+.
I was the first person to beat-box with hand farts. I'm a Boulder native. I designed the animation interface in Adobe AfterEffects. I toured in a band full-time for nearly 6 years. I've been a daily Mac user since 1984. I taught grad-level 3D animation as an undergrad. I know how to make fire, stone tools, traps, shelter, etc. ...with my bare hands. And I'm apparently a huge braggart.

Fantastic quality Indian food. Every bit is consistently top notch. Super delicious, very flavorful, always consistently excellent food. The chef is super experienced. Friendly staff. Best Indian restaurant in Boulder county and I have been to all of them many times. They claim that they will have a lunch buffet soon. Great location and their lunch special is amazing for the price.
