But did you swap the images? The contrast is not very good with Oly zoom, at least on this image. How did you make a setup for scanning, very interesting. I tried to scan with the digital camera, but outcome was lousy.
It is a slide copier attachment for the PM-1, it simply holds the negative and a shot is taken with a 50mm TTH enlarger lens at max resolution to get a RAW file, then through the Gimp to convert to Positive image.
Both the shots were exposed purely for the sky in the camera and after gimp processing, biased to turn the outline black. The path had to be masked to look the same, and areas around the tomb selected to remove bright spots from buildings in the distant view.
The copier was made by Reid and Sigrist for the Reid Leica copy, but BPM and many other bellows makers manufactured similar items to hold slides or negs to re-photograph.
The light source is important it must be very consistent, and "soft", so I am using daylight white 20 LED bulbs, set behind ground glass, to diffuse the light. Sunlight is the next best option.
