Hi! I'm the first posting here...



Anybody knows if Tri-X Super-8 is exactly the same film as Kodak TX400? I would like to experiment processing the 35mm in reversal before attempting a Super-8 reel...



Thanks!

I can't answer that offhand but could you do a snip test of the Super-8?

Thanks!

Yes, indeed. But as I'm testing several films, I just wanted to gain some time.

No, it's not. I will sniff around after empirical diffs, but this I know from my modest 16mm film shooting: You can't process Tri-X reversal as a negative with good quality. It's got a different contrast range.



How do you plan on processing? Lomo tank? Wad-in-a-bucket? Rewind tank?



I use a rewind tank and the timing is very much longer there than it would be in a standard still photo processing tank do to less time in direct contact with the solutions. Lomo tanks are the best, particularly for 8mm.

Here you have it (I knew there was some diff):



When processed as a reversal film, the resulting positive

can be used for projection or for duplication. If processed

as a negative material by conventional methods, the film

will yield satisfactory results,

although there will be some

loss in speed and an increase in granularity

Thanks a lot. Yes, after some testing, I've discovered that they're not the same.

In fact, TriX 400 on 35mm processed as reversal is a very problematic stock.
