Hi friends, I just wanted to put this here for the record, for anyone looking to reversal process Fomapan R100. I'm very happy with the results I'm getting, full ISO with good shadow detail, and nice crisp highlights. I basically follow this guy's process to the letter: (make sure you've got subtitles switched on) I even went out and found those 1.5 liter bottles that he uses (not cheap). My one alteration is to use Ilford's PQ Universal developer instead of Dokumol. It is more readily available here in the US, and relatively inexpensive. I also already use it for other photographic processes, so it just means one less thing I have to buy an keep on hand. Note that using distilled water really helps make these solutions last a long time. My solutions are: Developer 1: 200ml PQ Universal + 1300ml distilled water Bleach: 1200ml distilled water + 70ml 50% Sulfuric Acid + 15g potassium dichromate + water to make 1500ml Clearing Bath: 140g Sodium Sulphite + distilled water to make 1500ml Developer 2: 200ml PQ Universal + 1300ml distilled water Fixer: Ilford Rapid Fix My timings are (all at 68 degrees F) Pre-wash 1 minute Dev 1 8 minutes Rinse 30 seconds Bleach 5 minutes Rinse 1 minute Clearing 3 minutes Rinse 30 seconds Re-Exposure 1 minute Dev 2 8 minutes Rinse 1 minute Fix 3 minutes Wash 3 minutes Hypo clear 1 minute Final wash 3 minutes.
Hello folks, I'm new on cinematography.com, i'm getting into super-8 as a member of an analog associative Photo/Cinema called ZebraLab based in Geneva : https://zebralab.info/. I am also a photographer by job. With the guys from the lab, we are/have built two machines to cut reels of Fomapan R100 DS8x30,5M to 4x S8x15M to be loaded in Lomo Reloadable Cartridge. That make it really affordable as we buy from Foma factory shop, we are around 7€ for the film and around 3€/film for processing (detail below). According to Super8Wiki, Lomo Reloadable Cartridge acts as 64T/40D -> http://super8wiki.com/index.php/Super_8_Cartridge_Notch_Ruler (down of the page). We would like to turn them into ASA 100, but we don't know wich notch ruler we should trust : - The one from Super8Wiki : super8wiki.com/images/6/6f/Cartridgenotchruler.pdf - Or that one who says the Super8Wiki notch ruler is not that good : http://www.peaceman.de/schmalfilm/super8/S8_Notch_Tools_v1.0.pdf We asume that : as the Fomapan R100 is black and white and that the contrast change induced by the CCA filter is not that big of a deal for us whe should turn the ASA 40D to an ASA 100T, thus cuting a filter notch down on the cartridge and enlarging the upper notch, correct ? Also, as several of us own (and ZebraLab also) a Canon 814 XL-S in working condition, we would like to give a shot at turning one of the cartridge to ASA 400, as the film stock can be pushed 2 stop during processing : we are processing black and white reversal with a mix of two method : Potassium Permanganate + Sulfuric Acid bleach and using a photopaper developper, as the emultion if soften by the bleach, we do hardening bath before to the bleach and one hardening fix bath after second developpement. The hardening concentrate is the Tetenal one (Aluminium Sulfite + Acetic Acid but that need confirmation). You can watch the result here on a Kodak Tri-X 200. (i found the result to be a bit too much contrasted...) But, according to the Super8Wiki notch ruler we are not sure that the Canon 814 XL-S can read ASA 400, even if it say so on different website (that would mean not a notch is pushed by the cartridge, 6 notches without the filter notch, and we tried cuting into an old K40 to make it ac as a ASA 400T but it doesn't seem to make a difference for the exposure sensor, that same camera read and exposed correctly the Kodak Tri-X 200 that you can watch on vimeo...). So : is it possible to turn a cartridge to ASA 400T (or around like a 500T), and would a Canon 814XL-S be able to read it, it can read Vision3 500T, so i guess yes, but how ? That's it for the moment, if you have solutions and/or questions, i'm up for it ! Bye, Jeremy
Fomapan R100 Kit + Kodak Tri-X 7266 failure
Roger Cambell posted a topic in Film Stocks & ProcessingHello everybody. My name is Rogers and this is my first time posting on Cinematography.com Today for a school project I attempted developing Kodak Tri-X 7266 with a Fomapan R100 Kit in a lomo tank. I followed the instructions yet the project did not work well. It appears as if the whole emulsion was removed from the base of the film leaving it clear. My problem is I can't figure out at what step this happened. Would someone have any information on what could have caused this to happen? Perhaps it was during bleaching something went wrong? Also, it would be nice to understand the re-exposure part a little bit more. This was my first time so I was expecting some chaos. Thank for reading my post and to anyone who can spare some info!
Proportions on Fomapan kit
Luigi Castellitto posted a topic in Film Stocks & ProcessingHi! I have to develop Fomapan R100 double 8mm B/W reels (10mt each): i bought the development kit Fomapan R100 B/W and I have a Lomo tank that can contain only one reel at a time. Can you tell me what are the proportions of water and solution for each reel?
