TF-5 is not alkaline.

Drew, back in the day were there any other films that had a TXP-like retouching surface on the base side?

TXP is Tri-X 320, which is a very different emulsion than TX (Tri-X 400), and is fairly unique. It was originally designed primarily for low flare, studio/portraiture work. It has a relatively long...

Meh. Nothing particularly captivating from my perspective. Just basic mechanics.

It’s supposed to be clear sky all day here so I guess people will get their money’s worth.

I’m telling you, you’d have the best YouTube photography channel by a country mile, and you’d be a YouTube star.

Well, apparently all the hotels here and all the ski resorts in the eastern townships are full. Jay Peak just south of the border says this is making their season. Crazy.

You should really have one of them YouTube channels.

I think “…known for a very long time,…” is the key phrase. A hundred years ago, maybe.

I sort of did this back when Ilford introduced the reformulated papers, although the Moersch developers I used in the experiments were only the Warmtone, SE-3, and SE-6. I documented some of it...

Drew, PMT is short for Phenyl Mercapto Tetrazole. The whole point is it isn’t Benzotriazole (which does pretty much nothing as far as image colour is concerned) although it is related.

No issues with my 110xl, although (a) I bought it new - ie it had not been improperly disassembled and (b) it was from a relatively late production run. It came with the ooh-la-la Linhof engraving...

Yes and they also offer some good bulk chemicals for scratch mixing including some compounds which have been harder to source in recent years such as PMT.

Freestyle seems to carry some of the...

The split development experiment that produced the cold tones is interesting. I wonder what the mechanism would have been there.

You’re not missing anything.

Is BW-65 even made anymore?

Currently the easiest way to obtain PMT is to buy Bellini from Freestyle:

Or buy a bottle of Moersch Finisher Blue developer...

Yes the CT developer was out of production for several years before FBCT came along. There was Ilford MG Cooltone RC paper during the CT developer era, but I don’t know if that paper was the same as...

I seem to remember some old SDSs for both Moersch SE3 and SE6 indicating PMT but that was a long time ago and the current SDSs for those developers do not list it - although that doesn’t mean much....

One thing you can do is get some PMT (which is also the active ingredient in Moersch Finisher Blue). Add small amounts to any print developer and you get cold blue-black. Depending on how pronounced...

TF-5 is not alkaline.

The developing agents are CD32 and HQMS. The alkali is sodium carbonate.

Interesting. That seems like a strange recommendation and formulation. The carbonate of course is alkaline. Then when you add the bisulfite (acidic sulfite) the solution will become less alkaline,...

Marketing.

It’s hard to know exactly what John W. intended although I don’t remember his normal instructions for his pyro developers factoring in a carbonate pre-wash. To be honest it sounds a little strange,...

That’s great news!

One thing - if by pre-wash you mean before the developer, don’t do that unless you then give the film a thorough plain water wash before the developer. You don’t want any...

Yes that’s fine. Give the film a few minutes of soak in plain water first to get it throughly re-wet and then do the sulfite bath. 10 minutes in the sulfite with a little agitation here and there is...

The pH of the fixer shouldn’t normally make a big difference, but in some cases residual dyes that have not come out earlier in the process might come out somewhat faster in an alkaline fix, and that...

I don’t know… it seems less “elitist” than it used to be. Of course there also used to be a lot more active members so maybe it just seems less elitist now because there is so little going on.

Is this a current product? I couldn’t find much more information than the Agfa PDF and some relatively uninformative SDSs. That it comes in liquid concentrate form to be diluted suggests it is a...

I think this is correct - ie gold toning on its own will tend to give blue-black tones, and often the blue-black shift will be more pronounced on a warm tone paper than a cold or neutral tone paper....

I think you are right. My guess is the extra low EIs people assign to TXP are primarily a Zone System thing as TXP and HC-110 were a popular combo in the 1970s-80s. Given the shape of TXP’s curve,...

The Tri-X 320 characteristic curve is highly “upswept” with a relatively long toe and very high highlight contrast. It’s a fairly unique film in its tone reproduction compared with pretty much...

Sodium chloride would increase solvent effect - that's what Microdol/Perceptol use in addition to sulfite.

In any case, these divided metol-sulfite developers will generally all do the same thing...

An issue above is the difference in contrast, which makes evaluating graininess and perceived sharpness problematic. The image on the right looks more contrasty to me but not sharper. Although...

You’re probably thinking of Sprint: 247745

Their fixer is great and they also make the best stop bath in the business (not that stop bath is anything to be pondered over but just saying).

It’s not necessarily only photography, other artforms too. They’re different than sports because those are generally shared activities. I think it’s less about wanting to sell things per se and more...

Make huge prints I guess.

It looks to me like there is some optical diffusion softening everything, so nothing to do with exposure/processing as far as I can see. One way to achieve this is with some diffusion at the...

I wonder though if it’s a fake image taken with a fake camera do the two fakes make a real? I think so.
