Nick, this is a little known trick. If you contact your negs directly onto ( or even enlarge/projct them for large transparencies ) ortho- film (yes the kind used for line copies, halftones and lithographs!), then process the ortho in d-19, you will get great conversions. I would suggest setting up your system by starting with the d-19 at 68f for 4 min with continous agitation. Do a test strip just like making a print. you can control the contrast with the development/expopsure combinations instead or printing filters ( the same as the zone system for expanding/contracting the neg). don't forget to make sure the image and new film are emulsion to emulsion for sharpness.(posted 8203 days ago)if you do go the other route and copy your prints, i would not suggest the t-max kit. It has contrast and consistency issues, and the replenishment for it is not accurate enough for SLIDES. Try using the DR5 process. that will give you the consistency and control high quality slides need. good luck, any Q's feel free to e-mail me. George
