folegandros cliff b&w (higher resolution)
2.5X resolution increase by hand-stitching 3 frames. Not a perfect result, you can see the join lines if you look closely for them.
This is after setting up the Asahi Pentax Copystand II but before receiving the linear stage for precise shift of the negative.
Negative was taped to a piece of anti-newton ring glass for flatness and a homemade 6x4.5 plastic mask was used on a cs-lite to block extraneous light. There is less lighting irregularity than when the essential film holder is used, but still some, which is easily correctable in processing at least for black and white. f/8 and 1/60 was used to the digitization, at almost but not quite 1:1.
The process takes a few hours right now so not practical for large number of images, I'm hoping that with the linear stage, rotation will stay constant and it can be made faster. It should also help with the join lines.
