I've just seen a friend's album of old family photographs from 1930s Shanghai. The quality of the small prints is exquisite, even though they are not contact prints (they range from 2x4 to about 3x5 in size). Every time I see old prints like this, I am taken by the richness of the tones. I know these papers probably had more silver than modern emulsions, but there is something else (perhaps the matt finish) that makes the photograph look like you can touch the image directly on the surface - like a charcoal drawing. Can anyone explain this? These are simply-processed amateur photographs. I've used very good papers in the past (Oriental, Zone VI Brilliant, Galerie), but cannot duplicate this look.
