LOVE #2 And the DOF in #3 is nice. Maybe just move the camera a little to the right (or left) so the dome is not so centered? Just an idea. I like the tones, your conversions are nice.
two is fantastic. Absolutely wonderful photograph. Only suggestion would be to straighten it and recrop a little bit. It looks to be listing slightly clockwise.
I hate getting on the tail end to repeat others, but yeah, good shots. #2 is a standout.
Long ago, b&w was the only way to go, including your own darkroom.
I'm waiting to purchae a dedicated film scanner to bring back and share some of my b&w shots.
Nice work
