Harman Direct Positive Paper Question

[LFLarry]

I have been playing around with some Harman Direct Positive paper and I think I have my ISO and development down where I can trust it now.

A thought occured to me about this postiive paper and I am unsure of myself, so I thought I would ask the group here for some help.

When you expose the paper in the camera and process it, you get a positive.

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?

Try it and post

I think I know, but prefer you provide empirical evidence in a post

Good idea!

[LFLarry]

Yea, I will definitely try. If anyone knows what will happen, go ahead and comment, but otherwise, I will give it a try and see what happens.

Read the data sheet/ manual. It's all in there, including an example of printing a negative on to it.

Excellent idea. I didn't think of that. And, yes, the example is given in the tech sheet. Here is the link in case anyone wants it. https://www.ilfordphoto.com/amfile/f...9/product/720/

Thank you.

Larry,
Does the paper have any watermark in the base?
I am considering trying it for a project, but if so, it's a non-starter.
Thanks!

I have gone through about 3 boxes so far and no watermark on any of mine. I think you are safe.

Good to hear..thank you for checking!

Uh.... a positive print of a negative is... A negative! (i.e., no reversal of tones)

Note that normal photo paper is actually a negative material: it reverses the tones on the negative to make a positive.

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