black and white film?
hi, when i went to the store to buy my first safelight, the guy told me
that i can use this for black and white paper, but film can get ruined by it because it is still sensitive to red light. but if i use black and white film can i still use the safelight? i'm not very good at doing stuff at the dark so i'd like to use the light if at all possible. thanx |

You will have to develop your film in absolute darkness, even if it is just black & white film. But there are photographic papers that are not sensitive to red light, so, once your b & w film is developed and in your enlarger, you will be able to use a red light in your darkroom while you are exposing your paper in the enlarger without the red light fogging it. |

Rollfilm is almost always developed in a light-proof tank. The only time you need complete darkness is the minute or so it takes to open the film canister, load the reel and put the reel in the tank and close the tank. The tanks can have liquids poured in and out freely without letting any light reach the film. I would recommend a plastic Paterson tank for a beginner. If the reels are bone dry, they are very easy to load in the dark. You will still want to practice several times with a piece of junk film before attempting to load a film that matters in the dark.

You typically develop the B&W negative in a light proof tank (after loading it in complete darkness and closing the tank) in normal room light. Practice with a "waste" roll of cheap old film in normal light until you get the routine down ... it is quite easy. If your "dark room" has fluorescent lighting, wait a few minutes after turning them off before unspooling the film onto the reel.

I suppose you could use night vision goggles, but it is easy to work in the dark with a bit of practice. I find I can 'see' better in the dark if I close my eyes: it fools my brain into thinking I am concentrating on the task at hand rather than that I am lost in the dark. Go slowly and pay close attention to how things feel, be very deliberate in your motions. I would recommend a plastic Paterson tank for a beginner. If the reels are bone dry, they are very easy to load in the dark. I have trouble loading film if my hands are damp. I keep a towel handy when loading film on warm days. If hands, film and reel are all completely dry then loading is easy and fast. As Peter says: practice in the light; in the light with eyes closed; and then in the dark until you get the feel for it. Try and load the reel in the light with damp hands just to get experience with a jamming reel. I have a light tight container at hand when loading film. If the film doesn't load smoothly I put it in the container and come back later in the day and try again. Once the film gets damp/sticky there is no point trying to force it on the reel, let it sit for a few hours to dry out. The group rec.photo.darkroom is the place to go for more help on the subject, though I hazard half the folks on rpd are also on rpe35, the other half being on rpelf & rpemf. Message is now cross-posted to rpd. -- Nicholas O. Lindan, Cleveland, Ohio Darkroom Automation http://www.nolindan.com/da/index.htm n o lindan at ix dot netcom dot com |

As Peter says: practice in the light; in the light with eyes closed; and then in the dark until you get the feel for it. Try and load the reel in the light with damp hands just to get experience with a jamming reel. I've mentioned this before, but it never hurts to say it again. For those people who have trouble loading reels, someone invented the "apron" tank. An apron is a piece of plastic the same size as a 35mm roll of film, with bumps on the top and bottom. You just remove the film from the cartridge, wrap the film and apron together and put them in a tank. In a previous post, I pointed to a picture of one from the 1950's, and later someone pointed out that Freestyle still sells them. Obivoulsy it has to be done in the compelete darkness, such as a changing bag. For those that can not work in a changing bag, or do not have enough ability to use both hands to work an apron, Kodak made a day light loading developing tank, where you thread the film onto the reel in daylight, and turn a large knob. They still are available on auction sites. I find that I have much less trouble loading a reel if I keep my eyes closed. If you can not work in a changing bag, but can't locate a daylight loading tank, you can always use a windowless room or closet. It works best at night with all nearby lights turned off and the door sealed with a towel. Works best with low speed film. If it really is a problem, don't bother. Just buy a chromogenic film, such as Ilford XP-2 or one of the Kodak products (if they still make it the one without the orange mask) and have it developed, but not printed by your local one hour lab. Developing prints in a tray, is IMHO far more fun than developing film in a tank. YMMV. Geoff. -- Geoffrey S.

Sometimes when loading reels, I "see" what I'm doing, quite literally. The
brain seems to create an image in my mind even when there's no light. Unfortunately, it's not accurate. At some point in time, someone flipped your switch and had the current incorrectly dialed in. Then, as you mention, I close my eyes and no longer "see" my hands, the film and reel. Those beady little bug eyes, that bulge from their sockets? Strange?
