I recently have used fotospeed fd10 to process Delta 100 in 135. My impression is that this deverloper offers excellent sharpness, ease of use, and terrific tonality. However it is hardly spoken of on the forums. I won't say that it is as good as perhaps the catechol developers, but for a non-staining developer it certainly holds its own against the likes of Xtol, accutol, D23 or I guess any other non-staining developer commercially available. The fotospeed website claims it is second to none. It puzzles me that there is so little discussion of this developer. I would love to hear another person's o
opinion.
