Harman Direct Positive Paper Question

[Tin Can]

Good idea!

I have done this including enlarging 35mm slides to DPP to obtain a positive. It works. I like this paper for many uses.

What happens if you were to project a negative on to this direct positive paper via an enlarger? Would it still make a positive print or would it make a negative print?

Yes, you'd get a negative.

I'm only in the last few weeks converting from 4x5 to 5x7, expressly for contact printing DPP, as I have no way of setting up a full darkroom with enlarger.

I've been sending 120 and 4x5 film to dr5 Labs in Iowa; the gentleman there has a propriety process and processor for making direct transparencies from most b&w film, which scan well. They're gorgeous, tonal range is great. Each one is a little jewel, highly recommended (and I am not related in any way).

Once I've got some tests done, I'm going to be pre-flashing DPP and then contacting printing these b&w transparencies. I know pre-flashing can help with the stark contrast range, and I'll be trying different developers/dilutions for the same purpose.

Anyone with DPP and various developer history, I'd love to hear about it!
