Over on PN, Bujor was making paper negatives and positives in a camera using color paper.

It is possible to cross process Endura paper and make direct positive prints, but the contrast is high and the subject matter and filtration must be chosen with care.

Use Dektol 1:3 for 2' for the first developer, then a stop and reversal exposure. Then process as usual in the RA4 process and you can get a pretty good reversal print.
