RA-4 Pinhole?

Wondering if anyone here has attempted to do pinhole photography with RA-4 paper? Looking for some answers


My first question would have to be, what is the dynamic range of modern RA-4 papers? Could it even handle a high contrast situation.

Second is reciprocity. RA-4 papers are fast. But for exposure times needed for pinhole should a significant colour shift be expected? What sort of reciprocity factor should be used?

Would it make sense to use a piece of blank CN film on top of the hole to filter the light to daylight balance?

If so, what about reversal processing the paper?

Contrast will be *very* high. Compare to making paper negatives on grade 4-5 paper.

There is quite a bit about this on Photo Net going back about 5 - 10 years or so. Some did it to get negatives and others made positives.

In Poland is Boguś Biegowski owner of https://www.facebook.com/ciemnica.tl/ he make very big color pinhole. I saw it , so nice. You can ask him via FB.

Thanks for the responses/leads. Got plenty of reading to do this weekend!
