That’s a tricky one to diagnose. From what I remember of the Kodak framed holders there’s quite a bit of room for the sheet to move in the channels so that whichever way the sheet is loaded the...
You're probably right about the Benzotriazole in WD2D. There have been a few versions of WD2D over time. I recall John saying the original version contained Benzotriazole but that he later omitted...
Oh ok I see now... :) yes my discussions with Drew might appear quite confrontational - however it's mostly us teasing eachother about long-standing disagreements about certain things so at this...
Mark,
I’m not turning against the subject and I think it’s a worthwhile investigation. Hopefully you are able to sort out WD2H.
The working solutions of PMK and WD2H are virtually identical (+/- slop) in their part A composition. The difference is the alkali. If you replace the PMK alkali with carbonate you have WD2H.
...
Well, if you use PMK A with a carbonate B it’s essentially WD2H but it’s always worth a try. With the higher alkalinity of carbonate fog and non-imagewise stain would be expected to increase, but I...
Thanks for clarifying that - that’s good news in that it might simply mean you need to significantly extend development time with WD2H. That would make sense to me relative to WD2D since WD2H is...
It’s interesting you’re saying visually the WD2H negatives are noticeably thinner than the PMK negatives of the same scene. Even if we leave aside the difference in staining, if the silver density is...
It was musing more than anything else. Panchromatic films don’t have the same sensitivity to all wavelengths (for example there is often a dip in the cyan area) so the speed is basically an average...
It’s really the concentration of sulfite in the working solution rather than the ratio of sulfite to pyrogallol that affects stain. The difference between 0.2 and 0.3 g/l is small. All other things...
Maybe they are gas-hypering the film stock? It worked best on slow/fine grain films and special plates for astrophotography, that sort of thing. Or maybe they’re pre-exposing the film only to some...
For reference, here is a comparison of the contents of working solutions of WD2D, WD2H and PMK. I've excluded the EDTA-Na4 as it is sometimes there, sometimes not. WD2D originally had different...
I would say as long as the fixer relatively fresh, and you do a full wash sequence, then repeating a 60s fix afterward is like starting over so the subsequent wash procedure should be as efficient....
I’m not sure I understand what you’re asking, Doremus. I wouldn’t change anything you’re doing if it’s working well. I think if people have water conservation concerns it might be easier to do...
In the original work at Ilford that led to its archival/optimum permanence sequence it was found 30s fixing in the "film-strength" rapid fixer was sufficient. Since it was also found that extending...
LOL you fancy guys with your acreage. All I have is an apartment - but still no place like home.
I haven’t used Foma films but I’d be surprised if they have different dimensions than Ilford/Kodak. These things are standardized.
That BW King thing looks terrible for a variety of reasons but if...
I agree.
You can try adding either Benzotriazole or KBr. The
A standard print developer will tend to develop contrast quickly and you’ll typically sacrifice a little emulsion speed - not the best for...
One obvious potential problem I can think of when trying to use an unmodified film developer for paper is chemical fog. Film developers are not formulated to totally suppress fog - this is acceptable...
True. I also should have been clearer - I wasn't referring to your post (or Oren's). It was the rest that read like laughable "artist statements".
Sorry.
It's like you people are parodies of yourselves at this point.
If I remember correctly the H formula was more dilute than the D version, the goal being more contrast/stain for the petroglyph negatives he was making at the time, so maybe it needs longer...
Sal,
Thanks for correcting regarding SE3. I should have checked that first (it’s been years since I tried that developer).
I don’t think you will find Lupex to be an inherently blue/cool paper. I suggest trying basically any general purpose/neutral developer first. If on the other hand you prefer a cooler tone you might...
Drew, you should get one of those fancy Canon or Nikon digital cameras for when it’s windy. You can shoot at ISO 320,000.
This ^^^ is absolutely right. People invent complexity where there really isn’t any.
Cool stuff, Bob. I remember Ian Leake occasionally posting images on APUG years ago but didn't know he had a studio going and built equipment. Cone editions is an interesting outfit too. I'd still...
If it helps anyone I was told Harman just posted on Photrio the 2024 window is now open.
Is shrapnel grain sort of like buckshot grain?
I never much cared for Loranc’s stuff. Another guy who gives TXP a lot of exposure is Barnbaum. I’m not a fan of his either though.
I’m not much of a sentimentalist - it’s more A. Wyeth’s technique with tempera I admire. Anyway it was just an example of a 20th century painter who chose tempera even though oil superseded it in...
No, tempera like what people used before oils, and what some modern masters like Andrew Wyeth used. You should know that.
What is watercolour grain? Personally I like egg tempera grain but you have to be careful not to flex the film or else it cracks. And don’t overcook the eggs.
Edit: Never mind I found it in...
I don’t know… that doesn’t look like a very convincing shark, although maybe it’s one of those things AI isn’t good at like fingers. I kind of prefer my version though where it’s a drowning guy being...
Doremus thanks - I see it now. I will count this as one of my blunders :)
I haven't seen this ~~~~\o/~~~~~/\~~~~~ before. What is that? /\ could be the cosmological constant ? but not sure what the rest is.
Perhaps Tin Can was referring to AI having generated the exhibit overview/description above.
TF-5 is not alkaline.
