The problem experimenting with different pinhole sizes is that unless we are
making exposures of resolution targets

What about using a beer can? Is that to thick of a material?
Thanks.

Can you guys offer some info on making a pinhole for a 5x7 camera. I would
like to have about 135 mm. I have read some info and it suggested a #10

Thanks for any assistance
