The main difference between the two seems not to be the different settings on the camera (aperture, shutter speed) but the amount of light leakage!
And one of the double exposures.
Here are some samples from the image at the top, which were taken at 4800dpi. These are 100% crops. The first one is pretty impressive, but I note a lot of weird stuff going on in the second. It's like the scanner was guessing in some places.
Some people see things that are and ask, Why? Some people dream of things that never were and ask, Why not? Some people have to go to work and don't have time for all that shit.
