[Leica] Retouching enlargements experience?

[Brian Reid]

I have successfully retouched thousands of 16x20s and 11x14s with 
pencils. Little dots. Nobody can see the retouching without a magnifying 
glass. It is a very useful optical illusion. I always printed on 
Polycontrast G, but I suspect pencils would also work with an E or X 
finish.
