Yeah, I was sure there would be a big difference, I just didn’t know how much!
For reference, the top image was the 4/50 S-M-C Macro-Takumar, and the bottom with the pinhole lens which has a size somewhere between 1/3-1/4mm, giving it an effective f/stop between f/172-256. It was also my first time using T-Max 400, which I already knew was going to be way overkill for the pinhole lens. I noticed that the grain was about the same size between shots on T-Max 100 and Tri-X, and I suspect that even Tri-X is overkill when it comes to sharpness, which means there’s no reason why I shouldn’t be using the fastest, grainiest film I can find!
At least the Caffenol C-L concoction I’m working on doesn’t seem to be hurting me any. Yet.
This makes me really want to make another pinhole lens, with a much smaller hole…
