I don't have any actual data to back it up, but my guess would be that b&w reversal films like Fomapan R 100 and Adox Scala 160 have slightly wider exposure latitude than color slide film - but not nearly as much as negative film. When properly exposed for the highlights - which these reversal films must be (!) - I think I am getting more shadow detail from the monochrome film than I see in my old color slides. But I have not done any side-by-side comparison shooting to prove that.Wow, lovely. What is the latitude of B+W reversal like compared to color reversal?
I see you are in the UK and, possibly, already have some experience with Fomapan R 100 - so you probably know where you can get it processed.That looks fantastic, maybe I'll try a roll. I am already a fan of Fomapan R100 in 8mm cine film.
If you decide to try b&w reversal film, be aware that here in the US there is only one lab that processes it - DR5 in Stuart, Iowa. Also be aware that it sometimes takes them a couple of months to process the film because they wait until customers send in enough rolls to run a batch.That looks incredible. Thank you for sharing. I did not know there was such a thing as b&w reversal film.
How is it compared to E-6?I do home brew B&W slides. Its not really that hard. the most difficult part is actually getting some of the chems. If you are in the US, you can get them fairly easy. it does take a little testing to get proper film speed and first developer times, but not much different than starting out with B&W negs. they are easier to test, just pop them on your light box or in your projector. I find I get about 1/3 to 1/2 a stop faster than box speed with the process I use. so 100 speed film at 125 to 160.
I love the way MF B&W slides look projected (actually any slide film, color or B&W!). give it a try, its not hard to home process, just takes a little commitment. and its much cheaper than color.

not any harder. E-6 is not hard. the hardest part is the water bath to keep the chems as temp. home brew B&W slides has more steps than B&W neg development.How is it compared to E-6?

I used my FomaPan R100 chemistry (not their kit,[...].
Awesome. I know the film, have processed it as 35, 16, 9½, and the smaller formats. [...]
I process the cine film myself using ID-11 doctored with added chemicals to boost the contrast and make it suitable for reversal processing.....in a Lomo tank. So I'm familiar with reversal processing and can certainly give it a try with the 135 film.

I haven't tried the Foma kit. Easy and cheaper to make your own if you will be processing a lot.
1st Developer: 200ml Dokumol + 1300ml distilled water
Bleach Bath: 1200ml distilled water + 93ml 30% Sulfuric Acid + 15g potassium dichromate + water to make 1500ml
Clearing Bath: 140g Sodium Sulphite + distilled water to make 1500ml
2nd Developer: 200ml Dokumol + 1300ml distilled water
Fixer Bath: Ilford Rapid Fix
Buy potassium dichromate and Sodium Sulphite by the pound or more. Be careful with potassium dichromate though, it is bad stuff if you don't handle it properly.
I pickup my sulfuric acid at the hardware store as battery acid. It will last you a long time.......
Thanks, but unless those chemicals come with step-by-step instructions, they will do me no good. I have filed your recipe for future reference, after I have more experience. I would be more comfortable starting out with the Foma Home Kit.
You say you have tried a roll of Kentmere 100 in that soup, but "... a little more experimentation is required to get it perfect." What is it about your Kentmere results you think needs improving? Do you have any examples posted somewhere I could look at?
Have you tried either Fomapan R or Scala 160 in your recipe?
Wow! Thanks so much for that! Your example photos are encouraging, and your process sounds like something I think I can manage. I am off to shop for chemicals.I have step by step instructions but only posted the chemistry before so you can see it is easy and the components are readily available at photo retailers, ebay, and amazon. As far as more testing, sometimes I think the whites aren't quite white enough and other times I think they are ok. Blacks are deep and rich so watch out or you will lose detail. I couldn't find my gloves (keep the bleach off your hands) so I used the worthless swizzle stick in my paterson tank, you can see the air bubble artifacts from it and it was sticking, I hate the swizzle stick though it makes for a connector to a hose for washing. I use this to develop FomaPan R100 movie film in my Lomo tank. Next I'll be trying out Orwo UN54 since it is a positive/negative film and for the 400" roll it is cheap and has good reviews. The attached are quick grab shots of stuff in the yard during a smoke break while I was working at 100 asa. Scans are using default settings with no manipulation since I despise photo work on the computer. Projected they look good with better latitude than color slide, at least an extra stop either way.
Here is my complete instructions and the chemistry. ,,,

[...] Just please be careful with the potassium dichromate.[...] Watch for signs of exhaustion after about 6 rolls of 36 exposure 35mm I would guess. I used to process color slide before I lost everything, back when the Kodak E-6 kit was available and you could get bulk rolls of E-6 film. Nice to be doing transparencies again if only I could figure out where to get slide mounts in bulk cheap!
My reward for the test was out of the 6 slide projectors that I have one fried the bulb base, one sticks when cycling, and the 3rd one won't cycle at all. All worked perfectly last time I used them, grrrrr.... he first two are GAF projectors and the 3rd a Kodak. And people wonder why I have so many slide projectors. I'll be able to fix the GAFs but I won't replace the linkage in the Kodak myself (a hassle), I'll have to ship it off. Best deal I found for the repair with a cleaning and adjustments is $110. Glad I have 3 more Kodaks but you know they are on borrowed time too. And I just bought a zoom lens for the Kodak that failed........
Thanks for mentioning LeZot's. I will probably attempt the focus gear repair myself. The eBay seller where I plan to get the part also offers a mail-in repair service aimed at Kodak projectors which "won't advance" $85-115 + return shipping <link here> I haven't actually had anything repaired by him, so that's not really a recommendation. I notice neither LeZots nor my eBay seller say much about warranty on their repairs. Fargo Enterprises (link in post #21) says 6 months.The place I found for projector repair is lezots complete camera center. I'll probably pack it up in a month or two and send it off. If anyone has a recommendation I am all ears! I would do go the repair route. If they do a cla type thing and the repairs it should hopefully last another 20+ years. I am doing that with my Olympus bodies and a B&H 16mm projector.
