How light-proof are Paterson Developing Tanks ?
I have always loaded my developing tanks shortly before developing the films.
I've always done this - more or less out of habit. However, I did toy with the idea of loading the Paterson Tanks a few days before actually doing the film development. So it made me wonder - what does everyone else do and why ? I have never seen any claims or otherwise to the "light-proof-ness" of developing tanks. Its inevitable that where ever I leave the tanks in my house at sometime in the day they will be in direct sunlight. Does anyone have any thoughts or experiences they would care to share ? Thanks Martin |

I sometimes load my films a night or so before for convenience but then I leave them in my darkroom until I'm ready to process them.

If loaded correctly, Paterson Developing Tanks are 100% light tight. They are designed to be.

As far as I can see if a tank is lightproof for the duration of development, say 10 mins, then isn't it lightproof for say 10 years?
Having said that, on the few occasions I have had to chance to load a tank but knew that if I did I'd have to leave the developing until, say, after a meal so maybe 45-60 mins gap I have always decided to leave the loading until just before the processing Mike, whose belief in the powers of rational thought has but a thin veneer. |

One time I forgot to put the middle bit in and ruined a film. Otherwise as Mike says, I think they are light tight for however long.

I've never had a problem with Paterson Tanks, and mine are secondhand. Provided they are used correctly they are designed to be light tight.

I have loaded film into my Paterson tanks (both old and new styles) the day before developing the film and have never seen any evidence of light leak. This is true also when using Ilford and Kodak 3200 films, so I would say that to all intents and purposes they are 100% lightproof.

If you decide to do this, it would be a good idea to stick a bit of tape across the lid to remind yourself it is loaded.

The correct answer is quite critical. I can take a chance and run it through camera with possibly disastrous results or load a section into a reel and develop to see if there is anything there. I'll waste a bit of film this way but I cannot now think of any other way of being sure Mike |

Leaving teh tank loaded in direct sunlight does not seem a very good idea - black adsorbs light well and the film will cook.
