I decided to go all the way, today. Wow. Although I have to say that composing this tutorial, with the "help" of Blogger was the hardest part.
So beware: they are on Ebay "for Leica etc." but don't do that! And in July, at last, I got my Чаика: perfect! Very nice lens for half frame.
But what did I know. Took a modern Uсrainian Svema and remembered that double-Ilford, it was sooo thin and floppy. And I was right: the FED tore it to pieces.
The Russian standard-drum. I practised a bit, it's an inside-out half-spiral, a bit weird but not bad once you mastered the technique.
The (also Ucrainian) Reaktiv was a bit cloudy, but I used it as prescribed on the film, 7 mins and the negatives were okay, almost as I expected...
After two days the Fixage was grey/brown - never saw that, but it made the film very clear, so no problem here.
Oh, and the Leningrad worked fine, indicating nicely what I expected.
