I'd like to make a few transparencies from existing negs and thought someone here MUST have done so in the past. Sure would be nice if I could just use my current stock of Ilford Delta 100, as well.

Yep, I know the image will be flopped if viewed through the base, but any other hang-ups other than a gain in contrast?

Have any starting point suggestions for exposure via enlarger (height, f stop, time)? Or maybe exposure via strobe in the darkroom (GN, distance from contact frame)?

Developing in DDX...maybe a pull?
