All all this talk of printing on old paper and no one has shown anything. I do what I can here. These scans aren't quite as nice as the original. I only retouched brightness after scanning.
Ok here it goes first contact sheet of a step guide
All prints are developed in Defender 58D 1:1
If people are interested I will post times for exposure. Development was 4-6 minutes. Exposure 90 to 270 seconds. The Opal was in an enlarger everything else contact.
Order of paper Opal 1949, Illingworth ?, Velox 1954, Azo 1931
