It helps if you remember that the human race is basically a bunch of $#@%$# idiots.
(C'mon, you all know I'm right...)
Goddammit. OK, I'll be the only one to say it; I'm sorry, I'm sorry, I hate to be the patronising do-gooder, but if noone else is going to bother, someone has to:
This thread is rapidly turning into a 100% bang-on example of why (a) independent camera stores have a reputation for being staffed by up-themselves patronising snobs, and (b) in the main went out of business to be replaced by chains, who may not have known anything about cameras but sure as hell knew how not to treat their customers like imbeciles. (Oh, and (c), why APS and the like was invented.)
Honestly, you people. Were you squeezed out if the womb with an intricate understanding of photography already embedded as some kind of race memory? If not, how did you learn that film is light sensitive and you shouldn't pull it out of the canister? If you hadn't learnt/been taught it somewhere, you wouldn't know it.
My curiosity was piqued, so I just grabbed a couple of rolls of consumer film from the fridge to take a look. First, a roll of Kodak Gold 200 120. The following warnings/instructions are on the box:
Develop before 03/2006 (yeah, it's very old

.)
PROCESS C-41
FOR COLOUR PRINTS
There's nothing else written inside the box or on the foil wrap (other than the ISO.) I'm actually surprised - I was expecting at least an 'open in subdued light', but not even that.
Second roll I grabbed was Agfa CTprecisa 100 in 35mm. On the box
SLIDE FILM
PROCESS AP 44/E6
Process before 06/2008
DAYLIGHT/FLASH
On the inside of the box (which I bet most consumers never read) it says:
Set camera to ISO rating of film. The film should be protected against heat, excessive humidity, X-rays and harmful gases (e.g. formalin vapours.) Exposed film should be developed immediately.
Again, personally I was amazed. This is consumer film, not professional, and yet there is more text warning against formalin vapours (!) than there is actual explanation in English to joe-punter about what to do with the damn stuff to get it developed (like, 'always rewind film before removing from camera and protect from light', or something simple like that.)
Yeah, it's obvious when you know. 35mm is
not user friendly, though. People should be allowed to make mistakes and learn without being called idiots.
