This morning we went to the harbor of Harderwijk to see if my last and best pinhole "lens" works. The photo of the mill and botter shipyard was taken at ISO 50 under 3 sec exposure in cloudy weather. On the wing is a row of birds, neatly spaced from each other.
With DPP4, mainly the info from the blue channel has been used, the histogram of which has been slightly adjusted and the sharpness slightly improved. Then the photo was converted to monochrome black and white, and edited with the Analog Efix Pro program as if it were an old wet-plate collodion image in sepia tone.
The camera used is a modern Canon 6D Mark 2 in bulb mode. The self-made "lens" consists of a 0.28 mm pure round hole made in 0.05 mm thick stainless steel feeler gauge. The picture is glued into the center hole of an old Ore coin. The coin was then secured in a holder I had made from a water pipe screw fitting attached to an old camera sealing cap. The pinhole is located 40mm from the sensor (just inside the mount of the camera), so that the mirror just does not touch it.
I checked and measured the pinhole with a vintage National 30x hand microscope that I once found in a second-hand store for just 1 euro.
