The pinhole used is homemade and has a diameter of 0.5mm.

One nice thing about using a pinhole on a field camera like the Chamonix 5x4 is that the front standard is not fixed.
For these two images, I set it to 150mm which gave me an f/stop of f/300.

How did you measure the diameter of the pinhole please Ian? Were you able to control its size?

I would like to improve on one I made for use on my mirrorless full-frame camera so any hints would be appreciated.

I scanned the pinhole on the Epson scanner and then brought it into Photoshop and measured the diameter with the ruler tool
