More black-and-white photos

I've taken some more photos (3 rolls of 120 and 1 roll of 35mm) since my last post; here are some that I liked:

The last two were with a 20mm lens on 35mm film and I thought the exaggerated sense of perspective was interesting. The last one was a handheld 1/8 second exposure so I took a couple shots (because processing this film is cheap!) and just hoped for the best. I should've turned on the oscilloscope and captured an interesting waveform, though. Note the computer desktop background!

I don't know if this is a limitation of the film format, my equipment, or my scanning, but the medium-format photos (the first three) show a lot more detail and less grain than the 35mm photos.
