Yes, they do look good in green.
Taken at the Memorial Library south stacks. It's on State Street, big building on the right at the end.
I LOVE my fisheye (4.5mm 2.8 Sigma). I put it on the floor and scooted it down a hallway.
In Aperture, I upped the contrast and definition - the former just a bit and the latter almost the whole way to 1.00. I nudged the black point up about a quarter point. Then I tinted for the cross processing colors with the color tints and a yellow monochrome. i finished with a vignette to reduce the blue in the unexposed areas and. I dunno, make it grittier.
I decided to leave the black space and place it off-center. I just liked it better than centered.
