i needed a black and white C-41 film so i went to a local Camera shop and the man told me it would be £7 for the film
and i went "psh lets see it" because that is a tad expensive haha
and i seen it was out of date, so he got the manager and i got 2 for £3 instead of one for £7 ;D
ino yo get some strange effects from Out of date film and i also know some photographers only shoot out of date, but what exacly are these effects :D
its date is 01/2007 |

| As I've heard it, the general effect of aging on film is to make it faster than its stated ISO/ASA rating, so you would tend to overexpose if you don't compensate. But that's not very out of date -- I doubt its much different than normal, especially if it was properly stored in a cool/refrigerated location from the time of delivery until you bought it. |

Like wine, meat and women, film ages from when it's made, till it gets to where it is at it's best. Then it starts going down hill from there. Consumer film is sent out to be sold in a "green" state. It's not aged completely yet. From what I've read, this was done because the film makers knew that a lot of film sat around in drawers, in glove compartments, in cameras, on the store shelf, etc., both before and after exposure, for a long time. So they built in a aging time to compensate for this.
Professional film on the other hand, is aged at the factory until it's very close to it's rated performance. Then it's sent out, usually kept in refridgerators or freezers at the stores (this slows down aging a lot) until it's sold. Then it's either used and processed by the photographer fairly quickly or they keep it cold until they are ready to use and process it.
If old film is used, there is the possibility that it will be fogged. This can be caused by heat and also background radiation (the normal type radiation that is around us all the time as well as man-made radiation). But if it's kept realitively cool and protected, consumer film can be usable a long time. When old film is found that might be worth processing, usually a piece is snipped off of it and it's processed first to see what compensation in the process has to be made before the whole roll or sheet is processed. Usually normal consumers find a roll or two and wonder what's on it and send it in with the normal film and hope for the best. Kind of like most of us do with our wine, meat and women.
:D

| Does the same apply to Compact Flash cards? How long should I age my cards for before using them? |

Compact Flash Cards, don't need aged. Cameras however do, feel free to send me your 5D, I have an excellent aging process. You'll be very pleased when you (eventually) get it back.

Compact Flash cards hold their age more on the time scale of Twinkies.They can sit on the shelf for a very long time and still be good. ;)

I was just given an EOS5 film camera so I have a roll in it right now.. A strange thought crossed my mind too....
I haven't shot film in nearly 8 years... Bloody scarey thoughts there |

i've got a new hobby these days,
since i'm working in a photo lab:)
i take an old polaroid cam,
put two slices of expired color film instead of polaroid film,
and shoot without flash
two frames x two frames of usual color 35 mm film = one polaroid film
it's extremely cool to combine them on the editing machine!:D
the effect i get is fantastic:) but i doubt it's because of the expired film, more likely because of the combination of 4 frames
next time i want to try medium format film, but it's a bit too expensive for such experiments.. |

Film can be preserved for a loooong time if stored properly. That is to say, frozen. When I was shooting film in a studio and cleaned out the film freezer, I once found some 8x10 sheet transparency film that was 6 or 7 years old. The owner gave it to me and I shot it. The colors were just fine.
One reason film photographers buy film in large quantities is to preserve color balance. They'll buy several bricks (50 rolls/brick) of the same lot number and color test it. Then, they can determine what color correction and exposure compensation is needed to get the film to neutral, then they freeze the whole lot of it and thaw as needed. That way, there's no need to figure that stuff out each time. |

I dunno... I found an old 8Mb one and my 20D will not even take a single image on it in RAW.... I suspects it's something about size but not sure :-) The first fast 1Gb I bought was EXPENSIVE and now you can get 8 times that for the same price - seems like they age badly to me. :-)

Rocky Mountain Film Lab specializes in developing old film ... not cheap, but probably a better chance of recovering usable images than taking it to a local one-hour photo developer ... |

Yep, I use to buy my 220 film in bricks back when I shot a RB67. I didn't keep it that long so I rarely froze it although I kept it in the refridgerator. My wife use to get mad at me because I was taking up so much room and we didn't have room to buy a 2nd fridge just for film. Now I have one and it still has some 4x5 black and white and color film and 4x5 polaroid film in it that I'll probably never use, so I've never moved it to the freezer. I hang on to it though just in case I get the urge to dust off one of my old 4x5 cameras again. :D
