*house name removed*
I decided to go ahead and submit to *name removed* again.. and was rejected again.. but this time, I think I know enough to say they are so far off the mark, I have no real idea what they are thinking... some of the images rejected and their reasons..

Poor Lighting--Poor or uneven lighting, or shadows. White balance may be incorrect.
Umm.. uneven lighting and shadows are the POINT of this image.

Noise--Noise, film grain, over-sharpening, or artifacts at full size.
Noise and artifacts were kinda the point again.. to give it a grunge feel. Art?

Focus--Your image is not in focus or focus is not located where we feel it works best.
WTF? Here's a 100% crop..
These are just the three that have left me scratching my head.. and wonder why I bother with this kind of stock house. Technical reasons, I can understand, but one would think they would want to let their buyers decide about artistic choices...
Whatever... I think I'll stick with the stock houses that allow the buyers to decide.
