    I decided to do a test of the B&W films I normally shoot as well as a few other films I got from a friend and bought at the local store. why, not quite sure but I had some free time and wanted to do some playing. reversal processing is a little like neg processing. each film sorta has its unique developing formula depending on the developer. But me, not being a photographer ( I like it but dont claim to be anything close to resembling a real photographer) and someone who likes science/chemistry/physics thought it wuld be fun to try out. I have done B&W reversal and have two films I usually use, FP4 and ultrafine Xtreme 100. I have a pretty good routine and get very constant results, which I guess is the end goal. so I thought I would try out all my films, use the developing routine I have and see what happens. so I shot using a pentax 645n with the 150A lens and a nikon F3 85mm F2 lens.

    FP4 (35mm), ISO 50 to 400
    HP5 (120), ISO 240 to 1600
    ultrafine Xtreme 100 (120) ISO 25 to 250
    ultrafine Xtreme 400 (120) ISO 240 to 1600
    Tmax 100 (120) ISO 25 to 250
    Tmax 400 (120) ISO 50 to 800
    Tri-x 400 (120) ISO 100 to 800
    Rollei Retro 80s (35mm) ISO 25 to 200

    all films were shot without a filter and then with an orange filter just to see if there would be any difference in END results. End results were a simple viewing of the slides projected, as you would normally view slides.

    First observation. When I developed and enlarged/wet printed B&W negs, I never gave a big thought to the base color as it never seemed to make a difference. Not so in PROJECTING them. huge visual difference in the end results. The kodak films all seemed to have a slight olive tint to the base and as such they were the darkest slides when viewing. Next came the Ilford film which was a cooler light grey color. Next the Xtreme films, wich had the lightest grey color and as such had the second best projection result. maybe the lack of an AH layer makes the difference but there was a clear one when projecting. Lastly, or in a major way, first place was the RR80s film. having a truly clear base made all the difference in the world! wow was it awesome to view. I would say that this film gives velvia 50 a run for its money when it comes to projection. just jaw dropping Dmax. and even though it was black and white, there seemed to be so many more shades of grey compared to all the other films. Looks like I found my new B&W slide film.

    Next observation: a Filter makes no difference in the brightness of the slide. Maybe its because of an in camera meter, not sure. But the main difference as I expected was in the sky with cloud separation.

    Next observation: Tmax 100, like my prior attempt with Pan f+, did not come out at all. Way to dark. My guess is I need a more potent first developer.

    Next observation: HP5 had a very wide range of viewable slides. the shots from 320 all the way to 1000, 1200 in a higher contrast scene possbily, would work and I would be happy with the results. Xtreme 400 was very similar in range as well.

    Tmax 400 was a workhorse. the shots from 50 to 400 worked and all were acceptable. The greener base had an impact on the slower range, but still in a pinch 400 to 640 would work. an amazing film

    Next observation: Price is irrelevant. yes RR80 is the most expensive film but the base makes all the difference. the second best film, for my eye, was the Xtreme 100. Sharp, the lightest base of all the rest of the films, second best shadow detail and a very large exposure range. all the shots from EI 40 to 160 would have been satisfactory, with the sweet spot 100 to 125. The results of this and the 400 ISO film were VERY close to the FP4 and HP5. except for the base, I would say these films could be siblings. if I had to guess, I would say these films are ilford Pan 100 and 400 (but who's asking me).

    a long but fun two days. was it worth it, sure. I know know that I' gonna shoot RR80s and Xtreme 100 for my B&W slides. Not sure why I picked those 2 as I would shoot the RR80 at ISO 100 and the Xtreme at 125. But seeing as the Xtreme is $30 a bulk roll and the RR80 $72, it depends if its shooting for fun or shooting for quality. Either way I would be happy with either. I have included a quick snap of the light table with some of the films on it to show the film base colors. and while the picture may show the HP5 having a slightly whiter base, when projected its a little more grey than the Xtreme.

    I have nightmare (jokingly) about the demise of E6, so for me I have found a very good substitution for color slides. Its not a hard process and I hope those of you who shoot slides and B&W give it a go.

    John

    I actually like that olive tint! Must try out for myself!

    Wow very cool! That was a lot of work to put together and I am sure this will help lots of people who will be looking into reversal processing. It is a shame the Tmax100 didnt work out, that has a very clear base (in 120 format) when developed normally. What kind of medium format projector setup are you using?

    I understand these folks are good for this type of processing, and seem to have invented their own reversal process. It's not something I have any experience with, but stumbled onto them whilst reading on the Roger Deakins cinematography forum, a place where reversal processing is what they're all interested in over there.

    http://www.dr5.com/

    The website is hard to navigate, but here's the films they process. They're mostly about movie films but I assume they can do anything, as their price list has roll films on it.

    I'm using a hasselblad set up. really nice.

    would like to have had the tmax 100 work as it does have a nice base. I need to go back and experiment with the 1st developer a little more to see if i can get it to work. I just dont have enough on hand to give it a try any time soon. at the next film purchase might give a bulk roll a try and make up some short rolls to test with

    Thanks for that, very interesting. I have played around quite a lot with reversal and found I get the most pleasing results with Rollei 400s or Superpan 200 rated at 125, or 160 if the conditions are very bright. I like the effect I get with these films where my processing renders a moody tone with a darker rendering of skies but very clear highlights, I think their infrared sensitivity plays a part. Some sample shots attached. I had a go with 80s but at the time found it too contrasty.

    I only briefly tried with HP5 but without much success. I'm looking for a higher speed film to reverse process so will have to experiment again. I want 120 and 4x5 format so limits choice a bit. I think I might need to try a stronger developer. For 35mm I like the results with Adox Silvermax.

    the xtreme 400 works great and HP5 is not bad either. I use Dektol 1:2 as my first developer. works great. keep trying!

    Very cool. I do reversal all the time for S8 & 16mm and I still have not played around with using 135 neg films. Now I know what to do with that xtreme 100 that's been in the fridge. Some add restrainer Dektol, just out of curiosity, did you do this or use it straight up?

    I've done Tri-X as high as 6400 in HC-110 at high temp with sodium thiocyanate added, just to see if I could.

    I wouldn't mind trying Retro 80s out given how nice the tones appeared to me as a neg in Rodinal.

    There are various B/W reversal threads and for no particular reason I decided to pose a question on this one!
    Having got my reversal process successfully sorted with 35mm FP4, I thought I'd try experimenting with 6 x 6 slides via my Rolleiflex. Has anyone had any experience of this? I plan on using the same film. Exposure may be a bit more tricky, but I wonder what other issues I might encounter.
    Best wishes,
    Steve

    Great job John - it sounds like you had a fun couple of days! I am especially pleased to hear your evaluation of the Rollei Retro 80s, as I have been thinking about trying that one myself, mostly for IR work. I keep hearing good things about that film and am starting to think I am really going to like it. Especially reverse processed!

    I know this thread is primarily about DIY reversal processing, but I can't help sneaking in another recommendation for processing by DR5.com for anyone who might be considering reversal processing by a lab. The guy at Dr5 has tested out and basically optimized his process for each different film, providing what I think is a high quality and nearly unique capability. So far I have only had two rolls reverse processed there (both Efke 25 in 120) but they turned out just wonderful! His E6 processing is top notch too.
