I was intrigued to confirm just how accurately I could set the degrees of swing and the placement of the plane of sharp focus and depth of field using a longish lens. A 300mm is the equivalent of about a 100mm on 35mm.
I also found that I had developed this in Ilford Perceptol diluted 1+3. Perceptol is 100% Metol and used at this dilution gives great acutance.
