I don't think my printing video would be particularly useful for this scenario as it concentrates on printing from a negative. This process, if I understand it right, uses the camera for correct exposure, and then the paper is simply developed. I am not thoroughly familiar with the characteristics of positive paper or the exact best kind of development needed, but as I understand it, you would use a regular B&W paper developing process under safelight, and control contrast through the exposure, and length and strength of development. The general procedure is using trays to develop, stop, fix, and wash, in that order. The times for stop, fix and wash should be standard to the chems and paper. The developing times will have to be determined according to the exposure, developer, developer and dilution you choose, so there will be some trial and error there to arrive at what you will be happy with. Specific developer, developing, and dilution recommendations will best come from someone with more experience with this paper than me.
