Yeah I am "sure" I can't see a big portion of the image because it's too dark. You might want to consider going to camera attributes and setting the background to medium grey.

Black backgrounds and near black shadows means a big chunk of the image is lost in the shadows.

@HH: gamma, brightness whatever, all I know is I have to turn brightness or gamma up until blacks become greys to see the stuff that is in shadow. Black background renders with black shadows are hard to see.

I have my monitor setup so that black things are black not grey. But I can always bring the image into photoshop and brighten it up so I have a work around. But I think people run their monitors too bright.
