Printing color slides on Harman Direct Positive paper

[Ironage]

Anyone ever printed color slides on direct positive b&w paper. Seems like it would be easily done, but I can not find any one discussing this anywhere in my internet searches. Any ever tried this?

No, but it does sound like a decent possibility. Two caveats come to mind:
1: The contrast range of a typical slide may not match the paper perfectly - but thinking about it, it might match better than a real-life scene, so it's actually not such a bad idea at all.
2: You'll have to do with ortho instead of panchromatic sensitization, which may or may not be a problem, depending on artistic intent and source material.

Basically...sounds like one of those things worth a try.

I have done this as 4x5 contact prints. It seems like I landed on two Mississippi's from my closet's overhead light. You will need to experiment, expect lots of wasted paper!

If you haven't seen it, Ilford has a video about Harman Direct Positive paper on its YouTube channel:

Printing Direct Positive Paper

Yes I saw the video, but it only mentions photograms and in camera use.

you might look into using a yellow filter to tame the contrast a little bit, and if you have never done a 2 developer routine to develop paper negatives it might be a useful procedure. for years I have used 2 developers ... one is fresh and regular old d72 or ansco 130 type developer. the other. is the same developer but spent / used .. you put the exposed print in the fresh bath until the image peeks out of emulsion then in the spent developer for the mid tones and back and forth... this also works really well with caffenol c with a speck of whatever your fresh print developer happens to be, I usually put in about 20cc / 1L of caffenolc.. doesn't have to be perfectly measured caffenol or mixed any special way, I just use cheep rot gut instant and teaspoons / tablespoons or eyeball it if you are familiar with weights and measures needed...you should be able to make your prints with just a few test strips if you have experience with paper negatives, or want to do this first with regular photo paper to get the hang of the development routine that might be helpful ... ...

good luck !

Jnantz,

I have tried divided developers and have had decent results with Dr. Beers and graded paper. Also just a water bath without agitation just as the print emerges and then back into the developer can improve an image.

I gotta ask

Why?

I think that paper is out of production

If not, it is expensive

Very difficult to obtain a pleasurable image

I have tried it and have some waiting for Godot

I think the best way is to enlarge on to 4x5 B&W Negative sheet film. Otherwise, yes, transparencies are very difficult to print and really only good for projection these days, since the demise of Cibachrome.

B&H has it in stock in 4x5, 5x7, 8x10, 11x14 and 16x20. A 2'x66' roll is special order.
