Kodak TMAX100 VS Ilford DELTA100

[davetravis]

I need to copy my color slides to B&W film only once!
No time to experiment with too many possibilities.
I want the sharpest, finest grain, with faithful tonal range repro. I'll be copying 6x7 cm to 4x5 sheet film in my enlarger, and printing up to 20x24 inches.
Kodak or Ilford, which one?
Thanks,
DT

TMX is more neutral in this regard, so that's what I'd use for this purpose.

I would be amazed if you could tell the difference

Any reason why you're doing the internegative by projection rather than contact? I'm just curious, because I have some 35mm slides I plan to convert the same way, and TMX was my target as well.

Well I suppose I could just lay the 6x7 slide onto the 4x5 film in total darkness, and cut it out later. But I think I'll have more control with enlarging and have a bigger neg to play with later. Make sense?

I think it's good to dupe on a larger format.

The film for choice here would have been ektapan in the old days but tmax should work fine. I prefer doing contact internegs to eliminate the possibility of losing sharpness when making enlarged I-negs. By doing them by contact emulsion to emulsion you'll get the sharpest interneg possible, however it's harder to see dust when doing them by contact.

Wouldn`t that make the image laterally reversed?

35mm slides with a slide copier?
I would prefer Fuji Acros for that

No, I was actually going to try with my Leitz ELDIA. It's made for doing B&W slides on blue-sensitive or ortho film (works pretty well, BTW, I have some pretty nice slides from my usual negs), but with a bit of patience and some ingenuity, I thought I could devise a manner to use it with a pan film like TMX.

I'll vote for TMAX, too. I like both films, but I find Ilford to be more contrasty. In my experience both have very little grain (especially TMAX 100 done in TMAX dev.)
