Black and white slides! Reversal process at home
HTML-код
- Опубликовано: 15 сен 2024
- This is something I wanted to try for a long time already. So I finally shot a test roll of ADOX Scala 160 and developed it with a reversal kit from Klaus Wehner. Despite a lot of exposure errors I really like how it turned out! In this video, I'm showing the development process, photos and talk about other black and white reversal kits on the market.

For anyone trying the Adox Scala 160 or Adox Silvermax, I confirmed with Adox that they are the exact same film. They give it two different names because labs wanted the name to distinguish between the normally developed and the reversal developed film. B&H charge different prices, so don't feel like you have to buy the more expensive name.
In that case, does that mean I can develop my Scala in standard D76 chemistry and get negatives? I've developed Silvermax at home and got decent results. I know Adox recommend their own developer but in my experience standard developers work fine.
@@caketaster I bought their developer from Freestyle (which isn't cheap btw), and except in a few possible instances couldn't tell the difference between using the Adox Silvermax developer, and D76.
I processed Silvermax in Agfa Studional, as it is an excellent fine grain developer which lets the natural tonality of the film show through. Came out excellent, but not as fine grained as I would have liked. Rated it at 250ASA I think. Interesting if they actually are the same

I have never given a thought to making black and white slides. I thought your results were actually very good. Thanks for a good video.
Thanks for the very informative video, standard B&W processing is my limit at the moment. I collect Vintage cameras, fix any defective ones if I can, and then run a film through them, so none of these photos are important to me, they are just for fun. I have quite a lot of Ultra slow Kodak B&W slide film with no sprocket holes, I tried one roll, and like you the weather changed drastically, so all shots were under exposed as the only camera I have which will take non-sprocket film is a Saraber Geslar Finetta 88, which couldn't cope with the light levels, next time take a tripod 🤗😁
Since this was a bit ago probably old news now….ADOX now makes the kit for B&W film reversal that can be shipped safely. A film camera that has always exposed for slides perfectly is the Yashica Electro 35. It is an aperture priority camera but the speed is step less and totally determined by the camera so it can achieve dead on exposure by the electronic shutter. On regular film cameras your speeds are in increments that are fixed but in the Yashica you can achieve speeds of 1/35 sec. or 1/555 sec. Etc. very accurate. I know the camera is not all that much to write about but when it comes to slide exposures it is a great little tool. The fixed lens on the camera is great.
Very great review and live testing 👍🏻👍🏻
Looking forward to seeing your MF and LF projects. Keep up with the great work and wishing you a happy New Year
You did a pretty good job considering the lack of a reliable meter. I used to shoot a lot of Ektachrome and develop it myself but those days are gone, too expensive. I'll be doing B&W slides in the near future, just need to get the new darkroom finished up. I got tired of using a little corner of the basement. I have a 10'x20' room to use as a dedicated darkroom so it so that I can work on a much larger scale.
That is basically the same procedure that I use to develop 16mm movie film or 8mm movie film reversed. A 110 reel holds 6 feet which is enough to project in a loop, actually too long but it plays nicely in a movie projector.
Hey, I’m doing this with 35, 16 and 8 mm with half-homemade chemicals which are cheap and fool-prove to use. Try it out! These are the solutions:
1. First developer: Tetenal documol 125 ml, 875 ml dest water, 5g potassium thiocyanate, o,05 g potassium iodide.
Standard processing time:
7 min Fomapan, 8 min TriXPan
Agitate every 15 seconds for best sharpness!
2. Bleach: 61,4 ml sulfuric acid 38%, 10 g potassium dichromate, dest water for a total of 1 l. (Very poissones)
7 min processing time
Agitate all the time to avoid spots on the film!
3. Clear bath: 94 g sodium Sulfite, dest water for a total of 1 l
Processing time: 2 min
Agitate all the time!
Now expose the film to light (100 W halogen bulb, 50 cm) for 5 min in total, from both sides of the spiral.
4. Second developer:
125 ml documol+ dest water for 1 Liter
Processing time: 5 min
Agitate every 15 seconds!
5. Fixation: 200 ml express fixer, 600 ml dest water
Processing time: 4 min
Agitate every 15 seconds!
6. Wetting agent: adox adoflo some drops
Processing time: 1 min
Everything has to be mixed 1 day before and stored in full and closed bottles.
Temperature: 20 degrees.
Between every bath, the film has to be rinsed for 3 min. (Very important), after fixation 5 min.
It really works safely with great results! 1 l makes about 12 rolls, but it can be stored for several months if using dest water and u can mix less!
I also have a few rolls of the 120 Agfa Scala but if I shoot it i'll probably send it to DR5 for processing. Great video man!
+Alfredo Bustamante at least now it is prominent why it is rather expensive :)
How did it turn out?
I have been experimenting with Kentmere 100 and have had great results. Kentmere 100 is readily available and cheap. I'll be trying out other 100 speed films in the future. I use my own home brewed bleach and clear, paper developer, and regular B&W fixer.
Can you share some pictures of the Kentmere 100 developed as slide?
Back in the 1970's I did some reversals with excellent results. The film was Kodak's 35mm Panatomic X rated at ISO 32. The was a very fine grained film with outstanding dynamic range. The reversal chemistry kit was also made by Kodak. This was the only B&W film I tried that produced excellent results. I can remember being absolutely stunned when I first viewed the results of a B&W image projected large! The first time it is really quite amazing. I just recently got back into shooting 35mm B&W but didn't realize that there was still reversal chemistry available. And now with your inspiration, I have another world to revisit and explore. Thanks!
When I first started into photography, I was trying everything. B&W reversal slides was one of those topics which had an article once a year in the hobby mags, so not that big a deal. I used to have somewhere a box of slides I shot in 1962 at night at the Seattle World's Fair: lighted fountains, Space Needle, etc. Panatomic-X, ? first developer, light reversal exposure, Dektol second developer for maximum density blacks. Worked very well.
This is really cool, I'd love to have a go myself because I've got too used to the safety of developing negative film 😂 love the images and love your channel!
Thanks Tom! I also like the look of b&w slides, will definitely do more!
I like the result, which is very different compared to common BW negative films, couldn't see any grain at all, long and laborious development though!
10 bath process :) instruction for FOMA kit says: "reversal process is not a walk in a park" :D
Takes about an hour + you mix the chemicals every time right before the process. There are film stocks that require much less time for the first bath. So ADOX Scala requires 22 minutes, but Rollei only 3 minutes.
those b&w slides look so good! almost like darkroom prints if exposed correctly!
Exactly! And exposure was the hardest part, I should buy a light meter already 😅
@@SoExpired I did notice quite a few were overexposed so i would guess light metering is every bit as critical as colour transparency. They do however show fantastic tonal range when correctly exposed and are truly inspirational. It is easy to fall into the trap of expecting B&W film to have more exposure tolerance and lattitude when shooting B&W and colour negatives. Clearly the rules change when it is for transparency and become far more critical. Good luck with an accurate exposure meter and if the final results are critical bracket the exposures as well!
@@MrDegsy69 Thank you for the feedback! I relied on the built in light meter of the camera. Light meter in Zenit is not great :)
@@SoExpired If you can try and source something like an old Weston Master V. These can be sourced quite cheaply on e bay these days but do make sure you get the invercone with it. It is capable of making both reflection and incident light readings. The best method for exposing transparencies is measuring incident light? That is simply the act of measuring the light falling on your subject by placing the invercone on the the meter and pointing it towards the light source illuminating the subject ie the Sun, photoflood, light coming through window etc... Using this method you will be guaranteed perfect exposure almost everytime even in tricky situations like snow or against the light. Enjoy!
As a footnote i suspect the meter built into your Zenit either requires calibration or is being influenced by strong ambient light outside the framed subject area. We can source these meters on ebay uk for about £15. Print out the information contained in this link if you are getting one as it is highly unlikely you will get an original instruction manual with it unless you want to pay much more for one in pristine collectable condition

if you have a smartphone just download a lightmeter app, they work the same!
nice video man. that scala film is quite nice. subbed 😊
Thanks for a great video..I know this was a few years ago, but I'm interested in how the 120 and large format went. Also, were there any recommendations for tray processing sheet film?
Hi! Thanks for your video.
I have a question: I have a many slides films, but i have only black and white chemicals to develop films.... so... Are you tried to develop an E6 film using D76?
There is a list (I think it's on their website somewhere) of film stocks that Adox says works in the reversal process (more silver content, and clear base), but I was always under the impression that any B&W film could be reversed.
I though that too. Though reversing a film would require quite some experiments :)
great video, and very interesting process!
Is there any stop bath or water rinsing involved between steps? Thanks
What films can be acquired as black and white slide in medium format ?
Very nice work
where can i buy that developing kit?
Know that you can convert any black and white negatives into a slide with the ORWO 4185 process find the recipe on the Internet or if you want to send your instructions. For more information, I can write with confidence
very interested. do you have any examples?
Watch out that the ORWO process requires dichromate, and dichromate is very toxic, and also difficult to buy.
Using permanganate requires different first development times so one has to recalculate everything...
thats so cool
Thank you
Do you know anything more about using flash for second exposure? Will just firing it a few times from different angles do the job or does it require some more sophisticated magic? ;)
I know you can do that, though I've never tried nor I have a flash
Great video :D
Slides tend to be better underexposed a little. It's important to avoid blown out highlights.
Yeah, blown out slides aren't pretty :) But I tend to think it was an exposure error in my case. Shooting slides one, indeed, should be very mindful where to place zone V. Sometimes over, sometimes underexposing a scene.
It depends if you're dealing with Fuji or Kodak slides. I used to underexpose kodachrome slides (1/2-1 stop) for extra saturation and to avoid blown out areas. Ektachrome would be the same. With Fuji, however (Velvia, etc.) shooting at speed is better as those films already yield super-saturated pics. I wasn't an expert either at metering slides, but I've seen people who were and their slides of their European vacations just blew you away. No comparison at all to digital projectors. I have no experience with B&w slides, tho it's said they make beautiful prints. With an old style film like Adox, the general maxxim, "expose for the shadows and develop for the highlights is reversed in slide film.
Thanks for the info! I'll definitely keep that in mind.
I guess you'd like to try Darkroom Timer out - recently pulled from Play Store, but I have the APK. The app shines for one reason - you can define everything you like, as many steps as you like. Modern apps don't offer this as far as I know : )
By the way - I do this for some 2 years by Ilford recipe. Delta 100 gives me great slides
So you mix the chemicals yourself?
Great video....
Hi there, I just purchased a few rolls of the Adox Scala 160 BW and I was wondering how you metered your shots? I have shot positive slide film a few times pretty successfully and was just wondering if you should meter this film the same way or if you found it better to meter like shooting negative film?
Hey Victoria, developing for slides - metering for slides. Meaning that your metering should be spot on. My camera has a very vague metering thus a lot of overexposures.
So Expired Thank you so much for your speedy reply. I found it really helpful. The majority of my cameras no longer have reliable built in meters so I tend to always use a secondary external meter to be precise. Fingers crossed this helps cut down on over/under exposure issues.
I was interested in watching but I stop all videos at the first mid roll commercial and don't resume playback. Fix, that please.
Please buy a RUclips subscription 🤷♂️
Fomapan R100 also b&w slide film.
I've had a hard time finding a lab to process my roll of Fomapan R100 here in California. Recommendations?
DR5 lab? I couldn't find that film in the 135 format, that film in on the list of tested films for this developer.
So Expired oh awesome. I'll definitely have to call dr5 if they could process my Fomapan r100 film. Thanks.
does the printed instructions have time for rotary processing?
Yes
Why are you mixing 250ml of chemistry while the Paterson tank you are using requires a minimum of 290ml of chemistry?
Because I messed up. But 250 always worked fine for me.
Is it possible to develop Adox Scala 160 in standard b&w chemistry to get negatives? What sort of results would you get. I'm literally a continent away from anywhere that'll develop b&w using reversal process but I have D76 ready to go if that will get some sort of results.
It is possible you will get regular negatives that would any other silver rich film give you.
Wow! Are you able to enlarge them on standard black and white paper? :o
+segadotnet yes, but then you have to develop the print in a reversal process, otherwise it's gonna be negative on paper.
I tried using the rollei reversal kit but I ended up with a white roll after the clearing bath. not sure what I did wrong.
Hm... like heavily underdeveloped? I hope it was a test roll.
I wish I could get those in South Africa, I shoot quite a bit super 8 mm Scala film. And DS8 mm R100 Foma film
Hey Petko, did you try Rollei reversal kit? Foma also has a reversal kit AFAIK.

Difficult for me to get those overhere
Дмитрий сделай пожалуйста русские субтитры, у тебя интересные видео)) с меня лайк и подписка
Я постараюсь :)
its called b&w reversal film. kodak make super 8 tri-x reversal
Sure, you're right! Indeed it's being used as a movie film. For some reason it didn't pop up when I researched the topic.
250 mm for paterson tank ? i have the same it says 280 mm
You're right, mine says 290ml! Though I have _always_ used 250ml with no problems
Замечательно, тоже провожу эксперименты со слайд-процессом, очень интересное дело.
Какую химию используешь?
So Expired В основном самодельную, проявитель пробовал д-19, получилось очень контрастно.
+Видео обо всём а обращаешь в слайд чем? Просто смешиваешь химию по какому-то рецепту?
Can you give me the email of klaus wehner to purchase the develop kit?
and what about scala 50 ?
Roba Apposta Kit claims you can reverse any film. I didn't try
So Expired adox says you may develop it With foma reversal kit but i cannot find the instructions for it !
Лайк! Спасибо за видео!
подскажи пожалуйста где можно заказать набор химикатов?
johanneswehner.com/ не открывается.
Rollei выпустили свой набор и недавно Branco Ottico - Roba Apposta, но я их не пробовал
У парня тяжелый русский акцент
goose lol
Можно тут купить набор химии: shop.sreda.photo/goods/kit_for_reversal_bw_film/
