Hello everyone, long time lurker, first time poster. It's great to have such a large collection of analog photography users on the web. My friend's house recently had a broken water pipe downstairs, and it affected many of his photos. All of his film is consumer-grade film and local photo developers (grocery stores, pharmacies, etc.) For example, using this website: http://www.hamrick.com/vuescan/html/vuesc24.htm and reading the codes on the film, some of his color negatives are marked: 100-3 which is Ektar 100 Gen 3 (not sure if CX or SY?) 200-5 which is Kodacolor VR 200 Gen 5 They all seem to be C-41, is this correct? I am an amateur photographer (THE photographer in my group of friends), so he turned to me for help. The only developing I've done on my own is black and white large format T-Max and Tri-X, a few years ago. Before that, I just shot 35mm and sent my film off for developing. Nowadays, I shoot mostly digital except for the occasional roll through a Nikon FE or N2002. I feel like I know how to handle film and prints, so I'm confident that I can undertake the restoration of these snapshots. Plus, it wouldn't be worth it to send these off to a professional conservator, as they're mainly just snapshots. If you guys don't mind, I'd like you to read over my workflow, and interject any advice you have or correct any misunderstandings. -The first job (and by far the most time consuming and important) will be to clean the negatives. Many were in standing water for a bit. Some are stuck to each other, some are stuck to prints, some are stuck to the paper envelopes that the lab returned the prints/negatives in, and some are plastered to the plastic sleeves that the photo lab sometimes used. How should I go about un-sticking them? I've been reading, and it seems that I'll be mostly/all dealing with C-41 film. What is the point of formalin/formaldehyde in color process? Is it only to protect the film from becoming a petri dish, or does it also do something to the colors? The local camera shop in Austin, TX just happened to have a bottle of Kodak Flexicolor stabilizer III & replenisher for C-41, laying by itself on a shelf. It says on the label that it should be used to make 1 gallon, and that it contains formaldehyde and methanol. From what I understand, this is what I should use, but it has been discontinued? For the old 4x5, we would rinse the negatives in photoflo before hanging them in the film dryer, is a formaldehyde-free photoflo rinse bad for color negatives? If so, I am going to soak the various negatives in a cold solution of distilled water and the appropriate proportion of flexicolor to loosen them up from each other/the various other substances and then gently see if they fall apart. Will this mixture will be safe for all films I come across, if I accidentally throw in some other type of film? (black and white, E6, etc). If a formaldehyde-free photoflo rinse is not recommended for these films, what is the best way to come about more solution? Can I substitute this rinse: http://www.adorama.com/KKFCSRG.html Or should I buy a bottle of this off of ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290490408500#vi-content Or can I just mix the photoflo 200 I have with a certain percentage of formalin (from an aquarium supply store?) Also, how well-vented does the room have to be when using this bath? We were going to use Nitrile gloves, but should we have a vent fan turned on? The room we considered using is probably 400 square feet and is part of the central air condition. -The negatives are water damaged, which means mold. I have PEC-12, lighter fluid, and 91% isopropyl alcohol. I also have PEC pads to use as wipes. After the negatives are dry from the above rinse, should I use just the PEC-12, or does one of the other chemicals work too, either alone or in conjunction with the PEC-12? -For the prints, should I soak them in anything besides cold water? The ones that were just slightly stuck together I assume will be fine, but any damage to the prints is irreversible, from my previous experience. Does adding photoflo to the water help with prints? For the scanning portion, is this still the correct subforum to ask, or should I post somewhere else? I am going to digitize his collection. I have my old Epson Perfection 2450, and recently when my dad wanted me to digitize a lot of his old slides, I decided to bite the bullet on a Canoscan 9000f, since it has FARE (i.e. Digital ICE) and is LED, so there is no warm up time. Should I scan before AND after cleaning? Is there a potential for serious damage to his negatives that I should take such precautions, or are the cleaning methods harmless to film? I always just used the programs that came with the scanner, but now that I've been reading online, I am seeing a lot about Vuescan and Silverfast. Will I see a marked improvement in upgrading to one of these programs? After this, I will be transferring the negatives over to a more ordered system of archival binders and archival sleeves. I am going to scan the film at 1200 or 2400 dpi, while I assume that for the photos, I'll be able to get by with 300dpi, right? Thanks in advance for the help, and sorry for such a long post. I just want to cover my bases and make sure I'm taking good care of my friend's collection.
