In my opinion the best film for making positive slides from negatives is Kodak Technical Pan Film 2415 (Cat No 129 7563 for 135-36 rollls and 129 9916 for 150 ft rolls)developed in Kodak undiluted D-19 for 4 Minutes at 20 o C. You can also vary the developer and conditions in order to adjust the contrast range--see Kodak Publication No. P-255. If you want a positive slide from a positive image try Kodak Precision Line film LPD4 (150ft rolls Cat No 157 8327) for a reasonable one step b & w transparency.

Both Kodak and Ilford make a continuous tone direct positive B&W 35 mm film. I have forgotten the specific product code, something like 6330 for the Kodak film. It's apparently what they used to use for movies.

I have had great success using Kodak Technical Pan film 2415 (develop at maximum contrast, 4 minutes in D-19) directly through negatives sitting on a light table, using 1/2 stop bracketing.

David:
I used to use Tech Pan rated at ASA 125 and got beautiful slides. Used a Nikon on automatic mode with an aperture of about f:6 on a 90mm lens. Use a good light box.

Developed in D-19, 1:1 for 3min, fixed, washed and dried. If you use Orbit Bath in your fix your fix time is cut to 2 min and wash 5 min. Orbit Bath is good for printing also. Same times for prints. For TEM slides did the same. In the past I used type 4489 EM film for my slide. Tech Pan works rather well for making B&W slides from Negs.
