I want to try making chrysotypes, but I cannot find the process in

any of the alternative process books I looked at. Can anyone point me

to the formulae for this process?

For any photo I care about, I contact print. For me, enlargements are for snapshots. If I cannot carry much weight, I will bring a lightweight 5x7 or 8x10 and one lens. With enlargements, one usually has to view the print at a distance or it will look somewhat fussy, but with contact prints, I can use a loupe to find extra detail.<p>

When I was transitioning to contact printing, I made two negatives of each picture. One was lower contrast for enlarging and the other was higher contrast for platinum-palladium. I found I was not using the lower contrast negatives, so now I only develop for and print in platinum-palladium. I know silver paper can make beautiful prints, but pt-pd has become my niche, and working in both is too complicated. Bruce, don�t stop with Azo, give pt-pd a try.

A fresnel between lens and ground glass will cause curvature of the focal plane. It does not matter how the manufacture adjusts for the fresnel, the curvature will still occur. I can't stand a fresnel. I move my head around to follow the hot spot when focusing.<p>

It does matter. For example, FP-4+ is great for platinum prints because it can be developed to high contrast. HP-5+ cannot be developed to very high contrast and it is even slightly grainy in contact prints. The grain shows up as gritty highlights.
