Great find Randy, this reminds me that a while ago I found how to make AN glass in a similar paper, I believe it was an early Kodak publication, but despite my efforts I haven't been able to find it...
There is a german company specialized in graphic arts which manufactures several products suitable to this business.

I had a similar issue with a 5x7 back for my 8x10. Making a long story short, check the spring tension, mine felt fine but it failed doing enough pressure against the holder causing random light...
Pm me, I can provide you a PDF with the manual, and some directions to wire a non devere clock
New paper won't be too far from old figures, so you can use your current figures and see what happens. For contrast you can start with the ISO R figures in the data sheet. Exposure for the lightest...
Jobo ATL speeds are 75 rpm for 1500/2500 tanks, 50 rpm with expert drums. Changes direction each 4 turns or so.
Prolly way too late, but I'll let it here anyway, it may help others.
Turn the processor off, enter into service menu (F1+start+ON) then check the parts. Very rarely, but sometimes, the fault isn't...
Download the user manual from jobo site, look at tech bulletins, there is explained somewhere how to do that, as last resort you can unplug the battery that keeps the volatile memory, but keep in...
Since the " found star " story popped out the news all of it looked like an attempt of making as much money as they could more than bringing to light a great work. This had to happen sooner or...
I started using a 10ml pipette, but i got tired of them because they are a pita to clean with tea solutions, specially if they are equipped with a pump device
Heat it slightly and it will become more fluid. Watch the flashpoint of Tea, it can end in a real mess. For measruring I ended turning down syringes, pipes, etc. and just drop the syrup slowly in a...
Catechol stain is weak, but also renders beautiful, crisp negatives, usually easy to print. Pyrogallol stain is much heavier
I never got too fast oxidation with this developer. Stain and fog are even from run to run, even with a rotary jobo set at 24C. Ascorbic acid keeps it from it pretty well, sometimes too well ;)
On...
Oh, never tried T grain with it
Never had any issue, been using it for several years now but times out there looks like too short to me. Rotation, stand, manual agitation worked well. Subjectively speaking, I'd use catechol for...
A gentleman who will be missed. Sit tibi terra levis
A file sharing service, a kind of cloud storage. I said dropbox because it's popular, but can be any of the many out there.
Why do. Not place it in a dropbox ?
Don't mistake the minimum amount to cover a sheet with the amount needed to develop it. Concentration may reduce the amount needed, but if it doesn't cover it you'll end wasting film
Ultrafine has velvia cheaper
Expert drums are designed to be used at 50rpm, so they are used at that speed whatever the process is. Rotation reverses each few turns. Design it to do not stress the motor with 1 liter loads.
Last time I was in Rabat it was about 25 years ago, so my info about the city isn't updated, but I do visit the country often since I left. My experience is that the most of photography clubs i knew...
Probably not, this is like climbing, if it's not pushing you it becomes boring.
it's pretty good but all relative to b+f.
