Work and THINK in stop (and half stop) values, I second. Maybe a bit harder in the beginning, makes life so much easier thereafter. Test strips in fixed 5 seconds intervals will help you find the right base exposure. Test strips timed in full or half stops will help you find the base exposure...

IIRC Jensen in Germany is building and selling 6x9 projectors.

I see two problems here. One is the area of reduced density along the left edge of the picture. This one does remind me of scanning artifacts I get with a certain scanner with certain films. But there is also some dark banding in the sky area visible, running parallel to the left edge. This...

Ilford says: about 8-10g/liter is okay for film, fiber base paper only about 2 g/liter and for highest archival standards maximum 0.5g/liter. I think the differences explain why you cannot use the test for film fixer and paper fixer in the same way. At least not without adapting the test to the...

a tiny amount of petroleum jelly (Vaseline) spread out to form a thin, almost invisible layer will work ... I just found out :smile:

I would agree with Anon Ymous. Or you might just try to fine tune the dilution for your b&w wetting agent by doing some comparative tests. The manufacturers recommendations are only a starting point, as the dilution required for perfect results really depends on the hardness of your tap water...

RC portfolio is not new, in fact it has been around for years. The "new" is that is has been updated with the MGV emulsion, which was to be expected sooner or later. The problem with MGIV Portfolio at least here in Germany is that it was really hard to find a shop that acutally sold it. It was...

Hm. Any chance your blix is exhausted/breaking up and the deposit you see is on the prints is sulphur? Check the rubber rollers and cogs of the blix rack for the same white smear. I don't think calcium should give you such problems.

My experience with Rodinal is indeed that exposure (or density) will strongly affect granularity. Results can be rather unobtrusive even with a traditional 400 speed film like APX400 and 1:25 dilution, as long as you expose it sparingly, which of course requires that you chose subjects and...

No, actually I would prefer to be spared the hassles of de-silvering and dealing with the resulting silver sludge. But I just hate the idea that a valuable raw material is dumped when it could be kept in the cycle and put to good use instead ...

Have you ever asked there if the spent fixer is still treated separately for recycling? Until recently I lived in a German city with a population of 300,000. For years (starting ~2014, IRRC) I was told at the municipal hazardous waste collecting facility that used fixer is no longer separated...

This would be hard to believe. I assume what we see is that, with all the uncertainties around Xtol, some Xtol users are stocking up on Excel for the time being.

Kontur finders came in several versions. The most common marked "35mm" is indeed for 50mm lenses on 35mm cameras. But there is a "wide" version of this finder marked "f=35mm". Hard to find, but they pop up on Ebay every once in a while. This is an example

Well done! Thank you for keeping us updated with details of your project. I would be especially grateful for a follow up about how your DIY led light source works in practice.
