As far as technical aspects they all look kind of dim, or underexposed. It looks like you have a good grasp of the rule of thirds.Either my shots left everyone speechless, or no one likes to post replies.
So are these *fake* black and whites?
I like them,don't know why, except for the selective colouring of the bench.
Go to page 108/109 of your D90 manual. You can select Monochrome and make B&W images with your D90 without having to later convert them.If you can tell me how a D90 would shoot in B & W, please go ahead. The only way I can make color photos b & w is through photoshop. If thats fake then I don't want to be real.
