Pinholes

[Black Pearl]

I was gifted a Skink Pinhole kit for my Fuji this week and got a chance to try it this morning. Its the equivalent of a 24mm f110 (yes one hundred and ten) lens though you can narrow the FoV with extension tubes. Unfortunately using a pinhole on a small(ish) sensor isn't ideal as you are dealing with catastrophic levels of diffraction that really requires large format film.

However that isn't going to stop me experimenting and while I would like sharper results its not really about sharpness with such a basic imaging tool so I'll just have to be creative.

Looking at those images I'd say that the hole is quite non-circular, since I'm not familiar that particular kit I don't know if that is intentional.

BTW for large format the reduction in spot angular size is typically partly negated by more extreme f-ratios (for my pinhole for the Intrepid the range is typically 200-400).

That's an interesting set of images BP.

Really like the first pic Beepy... Don't know  why that bloke got in the way on the last one though ....
