    Pyrocat-HD works nicely with Ektascan and double-sided (green latitude). Been doing it this way since about 2008. Flat bottomed tray. 5 sec gentle agitation every minute. I always expose through a yellow #8, #15, or #11 light green filters.

    Thanks Jim! Is that for silver, or alt processes? I may try to get back to Pt/Pd with these negs, but for the moment Iím thinking silver contact prints.
    Thanks again,

    Was there a change in the rules? I can't see pictures. I would really like to see the images being discussed right now.

    Development by inspection works for any printing process.

    Is EKTASCAN B/RA gone? Are there any other single sided x-ray emulsions?

    ZZ has currently no availability but they say they're trying to source it. So far, the only option is this, but you need to have an appetite to buy 500 sheets:

    This was the first time I’ve dealt with bellows extension and reciprocity adjustments. I used the 1:1:200 dilution for 8 minutes, with agitation for the first minute and for 5 seconds every 30 seconds. It was still pretty high contrast of course, which I’ve reduced in LR. I bet it would still print on a #2 filter or paper, but I am going to reduce time and agitation on the second negative. [This is cropped from the full negative because there were some personal items on the desk too.]
