APUG.ORGHello, everyone! I'm new to this forum and new to the bromoil process.
APUG.ORGI want to try to make my Bromoil prints.
APUG.ORGMy Jobo ATL 1000 is working well on the E6 process.
APUG.ORGRecently, I've gotten 2 reels from one of the APUG members, I suspect they might have been cleaned with bleach, they are 1500 series white plastic, the question is can I use those with my slide film, and how do I make sure to wash them so that they are clean? jobo reels washed with bleach
APUG.ORGFor the small amount of film I now process, I've switched from C-41 to the C-41RA process. The RA process uses faster bleach and fixer solutions, for a total process time of about 8 minutes.
APUG.ORGWould there be a local source for potassium ferricyanide?
APUG.ORGHi all, a question. I want to increase the contrast of a print by using Fotospeed Sepia kit bleach by lightening the highlights. However, I want to sepia tone the prints afterwards. If I were to put the print in a bath of toner, the silver will still be there and will be redeveloped to silver sulfide as you know. If I were to re-fix the print after the bleaching step, stripping away some of the silver would the print bleach and tone thereafter? I haven't tried this before so would be grateful of ... Toning after bleach and re-fix?
APUG.ORGI usually work with the Kodak farmer`s reducer in my photos. I follow the instructions that Kodak give for working with negatives in my papers: Part A (farmer reducer) dissolved in 473 ml of water; Part B (Sodium thiosulfate, anhydrous) also dissolved in 473 ml. Then, I mixed equal part of each stock solution to prepare the final solution that is supposed to be active for, at least, 10 or 15 minutes.
APUG.ORGI find myself perilously low on C-41 bleach and was wondering what people think about reusing the bleach. I use Fuji-Hunt chemicals with the separate bleach and Fixer. I processed some film today and saved the bleach. I gave it a rinse between the developer and the bleach, then saved the bleach. I use a Jobo CPA-2 and can give it more or less time if need be.

APUG.ORG(Thought for some time whether to post in the Color or in the B&W category, but given the reasons for doing this I figured it'd be more interesting to people shooting black and white.)
PETAPIXELThese bizarre looking images are what you get when you “modify” chromogenic prints with chlorine bleach. Flickr user has done a number of experiments with these technique, and the results are pretty abstract.
APUG.ORGJust wondering if H2O2 can re-oxidise spent bleaches of various types, since the H2O2 would then just leave water behind (and the bleach)? Can H2O2 re-oxidise spent bleach?
APUG.ORGI've got a little problem here. I work at a school and we have no more money in our budget. I've just run out of C-41 bleach but, I've got a lot of E-6 bleach. In a pinch can I use E-6 bleach for my C-41 films?
APUG.ORGHello, I just started experimenting around with alternative color processing, my question is whether I am making an effective Copper Chloride bleach by employing the electrolysis of a salt solution with copper anodes/cathodes (which I do outdoors) and then filter the copper oxide precipitate. Does the solution contain enough copper chloride to do the trick? Also can this be combined to make a Blix or should I keep it separate? Alternative Copper Chloride Bleach?
APUG.ORGI've done a lot of looking and have found much discussion but no formula for using a separate bleach and fix instead of an RA-4 Blix. Since separating the two makes for a very cheap long lasting bleach why not do it? However I have not been able to find a correct formula or time for room temperature tray development. Farmers Reducer has many proportions and I would like to feel secure that I am not shortening the longevity of my prints. I imagine the fix would be a paper strength rapid fix for 2 ... Bleach not Blix RA-4
APUG.ORGI have a little over a gallon and a half of kodak flexicolor bleach iii for sale (cat 894 0801). This was the go-to c-41 bleach recommended for rotary processing in a jobo. It does not need a starter, has great capacity and is no longer packaged in this size by kodak. I purchased this from Diversified last year for a little over $100 (hazmat charge plus $35 per bottle). One bottle is unopened, the other a little more than half full. $45 shipped via fedex ground anywhere in the lower 48.
