Besides, other people are doing it with homebrew recipes and dammit them people don't seem so smart. so it's like humiliating to have to buy a kit--it's like an admission that some people out there ain't so dumb after all, and a total lack of hipster 'on the cheap' kool. pure ego.

    Has anybody having problems doing reversal actually TRIED to use one of these kits FIRST? From what's been posted, it appears not.
    John, the first thing I did was to buy the Foma kit. In fact, I only ever wanted to use a kit. When I spoke to one of the knowledgeable team at Silverprint in London about dev times, he strongly advised against using the dev part for Tri-X. He said that Tri-X is very low contrast compared with lower speed films when reverse processed and that it needed a very energetic developer. He suggested PQ which is where my tests started. Funnily enough two sets paper developer tests failed (with me) to return results with the contrast I sought. I'm not saying that the Foma will not work but I did start out with the desire to use a kit. And no other kit is available in the UK. I don't think you can say that 'nobody' wants to buy them based on a sample of 1 (after all, I think it was only me here trying to do it on Tri-X). And I do hope you're not aiming the 'hipster' slander at me - you simply have no idea on that score

    But I'm not one of the great disappointed. I realised very quickly that I had to run plenty of tests for both practice and knowledge before I went into my real film projects, with a solid repeatable developing process under my belt. Practicing on Tri-X 35mm was only ever a means towards another end.

    Now, it appears to me that a few people with no real interest in reverse developing Tri-X have jumped in here with an intention to criticise, for no good reason other than to gloat.

    When I have good results on Tri-X Super 8 (with D19 or Dektol powder) I will return. I may even also later try it with 400TX 35mm again out of curiosity. Other than that it feels like this thread has run it's course. I certainly have learnt what I need to know, for now. Thank-you to all who contributed.

    Ahhh, but I did not say it was impossible. I said that differences were small but real and the old kits had instructions for a variety of films. So please don't put words in my mouth. The old kits had a myriad of instructions for different films, but the new one has been "optimized" for T-max. That is all. This is my second post on this in this same thread.

    I did not say it could not be done.

    In fact, with adjustment, It could be used in this case, but we don't know what times to use for first and second development. Nor do we know the proper dilutions for the developers (if any). These were all spelled out in the old kit.

    And, BTW, I searched for the kit I used to have and it is gone so IDK where the instructions are. I'll keep looking.

    mostly true

    What PE states is more or less factual. ALL reversal kits are not created equal - in my opinion, most are bad. The FOMA kit is for the FOMA-r film, thats it. The posted ILFORD recipes on the ILFORD site should be deleted. Consistent reversal is not as easy as some might think it to be.

    This is like saying that you can't develop tri-x using tmax developer and you can't develop tmax using hc110.

    Also--if you substitute a different film for a certain process, it's best to keep the process the same--that is do NOT start off fiddling with the process times for different films, it is more appropriate to adjust the EXPOSURE of the film to the process. Each film has a different EI for reversal processing than it does for negatives in general. This is because when you're developing for negatives, you are using the "first" portion of the film curve--when it first starts to take off. However, when you are reversing it, you are, in general, using a portion of the film curve further "down the line"--so you generally need a bit MORE exposure to make the reversal work. Mr. DR5 has a table on his website of film speeds for DR5--this is an EXCELLENT starting point. One of the first adjustments people seem to have trouble doing is exposing somethign that SAYS "EI 400" on the box at a "reduced" EI like 200 or 100.....they seem to think the PROCESS is messed up if you can't get the "full" film speed. However, for reversal, "full speed" is usually somewhat less then the full negative speed in general. So people will trash a perfectly sound process because it seems to be defective if it can't get "full speed" out of the film.

    ALSO===you CAN SAVE those reversals that are "too dark"--use ferricyanide bleach. It's even conceivable to make an end bleach step part of the reversal process--after 2nd developer, say, you then give it a bleach bath and final fix to clear up the highlights. Then this is like "developing by inspection" but only in reverse. This has the effect of "pushing" the film "after the fact". Or, it's like the hypo in the first developer but more controllable and done by insepection instead of blind.

    NOTE--the bleach ALSO works for black and white fuji instant film---got an exposure too dark?...you can save it--put it in the bleach--it WORKS!
