Pinhole Photgraphy question
I recently came across some pinhole pictures people took using a dslr. I see alot of people use lens caps with a hole drilled in the middle. Has anyone attempted this with their alpha? If so, I would like to cut through the process of "making" my own 'lens' by seeing how others have done it.
Maybe sharing some pictures if you have them as well.
Needling real glass options ...
A "laser bore" is almost mandatory for a good pin-hole solution in a lens cap. There are a couple of people who do this and I considered it, a while back, until I realized it was a great way to suck dust into your camera, by operating the shutter with a wide open hole in the lens compartment. I decided on using real lenses, instead. The results seemed more consistent.
With film, though ... while I was attending college, I was going to fashion one out of a brick! Using a Polaroid film back. How barbaric, eh? I figured the brick would be the perfect way to say ... "simplicity."

No lens ... still an option
Using any of the TAMRON Adaptall II lenses, you get a "no lens" reaction out of the camera, also, because of the lack of electrical contact connections between the lens and camera. Believe me, I still have pictures out of the α100.
I have to admit, it takes a bit of thinking not having any aperture reading and the camera defaulting to f/1. You had better know you f/stops for your settings.
