Hallo Forengemeinde, hat von Euch schon jemand Erfahrungen mit dem Fomabrom Variant, das es seit kurzem hier gibt, und dem Splitgrade von Heiland. Mit welch...

Hello everyone, Has anyone here had any experience with the Fomabrom Variant, which has recently become available here, and the Splitgrade from Heiland? What settings should I use to get a first (usable!) test strip quickly? Unfortunately, I won’t be able to try it out myself for a few weeks… Best regards! Johannes

Not yet, but we’ve asked Jürgen Heiland to test the Fomaspeed Variant III and Fomabrom Variant on Heiland’s Split Grade paper. He’ll be doing this for version 2.5. We’ve also been able to test a few other papers: Agfa MCP-MCC, Kodak, etc. Best regards, Robert

Hello Robert, I don’t quite see it that way when it comes to removing documents. I’m sure I’m not the only one who still has quite a few MCP/MCC documents in storage. Please ask Mr Heiland to hold off on removing them for the time being. Although it doesn’t really matter to me, as I don’t (yet?) have a split grade. Best regards, Franz

He won’t have time for it until the summer. I’m now checking whether the emulsions are consistent, because if there’s too much variation, it’s no use. The split grade storage is pretty full, so having fewer papers on the market just creates extra work. Best regards, Robert P.S. Of course, you’re not obliged to carry out an upgrade; it also depends on which papers you use.

Hello forum members, I’ve been having a bit of a play around (without any scientific pretensions): Using the Splitgrade setting for AGFA-PE paper, you can get the exposure times and gradient of Fomabrom Var.III quite accurately; however – and this is surely the crux of the calibration – the changes in exposure time that result from changes in gradient . But at least you get the first (acceptable) test strip straight away – the rest is just fine-tuning. Best regards, Johannes

Setting: Other – medium speed Neutol WA 1+12: T -0.4 G +0.7 SE2 1+12: T -0.2 G +0.7 SE6 1+12: T -0.4 G +0.6 Development time: three minutes in each case. These are my practical values, not an exact calibration. The values are so close together that comparable formulations are expected to yield similar correction values.

Mr Moersch, Thank you very much for providing the figures! Warm regards from Salzburg! Johannes
