Film Question?

Hi all,

What is the difference between colour negative film and colour reversal
film?

What are the products of the film also - ie: I can take colour negatives
to the lab and get standard prints, can I also do this with colour
reversal film, or does it give a different end product?

Also, why is colour reversal film generally stored in fridges in the
shops - would I need to store it in a fridge prior to use?

many thanks in advance,

Rob

Most reversal film nowadays is sold to professionals who like the idea of
having "mature" film all the time. Once film reaches it's maturity, it is
stored in a fridge to keep it that way... The same with professional neg.
film.

]You can get cibachrome prints from trannies but they are much more
expensive than neg prints. The best idea if you intend to shoot trannies is
to scan them yourself or get the lab to and print them on an inkjet.

A negative results in a frame with inverted 'colours' (needs the
printing/scanning process to get the colour how you expect it to look), a
transparency (reversal film) results in a positive image (looks like the
scene you shot, assuming decent metering)

Once upon a time, you had to get a Cibachrome made ($$$) or they would make
a internegative, which was a negative they take of your slide which they
then print. These days you take your slides in to a digital equiped lab
which will scan them and print onto 'real photo paper'

The 'mature' comment sums this up as simple as you could... I can't think
of another way to describe it. The 'pro' film is delivered at it's premium
and keeping it cold keeps it that way. Consumer film is apparently designed
to sit on a shelf for awhile.

Should you keep it in the fridge??.. maybe.. I do, but it might sit there
for months... maybe a year or so in my case as I hardly use any but I keep
some on hand just in case! I tend to keep one camera with Fuji Sensia in
it, one roll in my bag and the rest in the fridge. Once I use the roll in
the camera (every few months), I load the one in the bag and pull another
out of the fridge. I keep some 120 roll film Reala/Astia & Provia in the
fridge as well on the off chance I need it. I keep my B&W film (except two
35mm bulk loaders, they are in a box.. don't ask me why!) in the fridge (BTW
I have a dedicated fridge for this in my darkroom) and we keep my wifes
Superia 400 in there too, mainly just to keep it all in the one place (she
buys several 4 roll packs at once).
