I know someone here should know this???

I was about to devlop six sheets of Royal Pan from a Grafmatic. It came pre-loaded

Then I relized that I had no idea about devloping times??? I have D-76 only at the moment... I've searched for an hour and came up dry, so to speak...

The best I've found in an old data book is :

DK-60a - 4 minutes
DK-50 - 5 minutes
Dektol - 2 1/2 minutes

All for tank and intermittent agitation which is what I do.

The only cross reference I can find is the data sheet to Tri-X. For the TXT version, it lists:

DK-50 (!:!) - 5 minutes
D-76 - 5 1/2 minutes

All 68 degrees...

DK-50 and D-76 come pretty close. Is it close enough to say, add 10% time ( 5 to 5 1/2)?

I shot the Royal Pan at ASA 200, the recommended speed...

Anyone know???

Thanks!

Adding to my confusion, on a quick chart it also states:

For Super-XX:

D-76 - 16 minutes
DK-50 - 8 minutes

Twice the time for D-76...

Panatomic-X:

D-76 - 16 minutes
DK-50 - 5 1/2 minutes

Three times the time for D-76...


Now what???

My 1972 Amphoto B&W film guidebook shows Royal Pan sheet film in D-76 for 8 minutes @ 68F, 6 minutes for Dk-50 1:1, 4 minutes straight.
If it will help, I'll scan the page and send it to you.

You might want to extend the development time by 25% and add some benzotriazole or Edwal Liquid Orthazite. I got a sealed box of Royal Pan from 1969 and made some tests with it in Acufine+Liquid Orthazite. Base fog was really high, grain was interesting, speed was probably around 200-320.

Thanks Top!

I guess that's the problem of being so single minded or so. I only used Plus-X and Tri-X since I can remember. Although back then it was in Microdol-X. Seems they favored a lot of "X"'s No doubt I have info from the early 70's around somewhere but darned if I can find it...

David. Thanks, but I don't have any laying around and it's not all that important. I also have no idea how old the film is? The person loaded it a couple years ago for me, or so he said, as I remember, I think There shouldn't be any shot in this group that wasn't doubled on HP5. I just thought it would be interesting to shoot it and see what it looked like.

I'll give it go and hope for the bext. Seems this whole batch just wants to have problems though. Nothing that can't be remedied one way or the other, but it just seems like I should put it all on the shelf for a while... Or shelf everything else and pay attention to what I doing?

Rich;
That time was for continuous agitation in a tray. Tank times are 10 minutes for D-76, 5 minutes for DK-50, and 8 minutes for DK-50 1:1, all at 68F.

(next time, read the WHOLE table....)

Ohhhh...Too late!!!



But, seems like it didn't make much difference...

They're still sitting in the wash, but I pulled them out one by one for a quick check. They're all dark transparent grey. Maybe a stop darker than an 18% card... Nothing... One might have an area of a lighter shade, but that's it...

Too middle-grey for non-developed. Over developed should have shown some details. But these have nothing but a smooth dark grey... Transparent, like I shot the 18% card with them. So it looks like development took place. And they're too light to have been exposed directly to light, not that dark or opaque...

I'll have to try and match up the notches when they're dry. Maybe they're not even Royal Pan??? Thank goodness I didn't rely on them for anything...

Well, I can deffinitely say after this that I certainly won't buy any Royal Pan!!!
