I haven't made a pinhole photo since I was a kid. Seemed like magic

I used a photodiox lens adaptor on my camera with a sheet of ordinary
kitchen alu-foil. I punched a hole (about 0.47mm) in the center.

I think the hole is not perfectly round and that the dimple on the back
side contribute to the hazy look of the image.

It's also a great way (as you can see) to see all the crud on the
sensor! Gotta get out the cleaning kit obviously...

Not satisfying at all - so I'll look into buying a "precision" pinhole.

If I get better results with that I'll look into more interesting subjects.



As for the pin hole use a thicker foil, I use a aluminium tape.

When the foil is pieced the hole is much sharper than using cooking foil.
