Hi all,
someone has links about color process?
TIA
n!

Congratulations on submitting the vaguest question of the year! What
specific color process are you interested in learning about?

I'm sorry, I want to learn to process color film, I found a agfa process kit
70 and I don't know if is good or not

PS: I'm a newbie for color process :)

 For Agfa process check the Agfa website. It includes some info on the kit.
For C-41 in general check Kodak's website. You want to search for document
Z-131.

Thanks

What is the kit? When was it made? What does it say on it? Do you
understand all you will get is color negatives, which can be had for a
pittance at any lab?

Yes it's good - it works. Creates colour negatives. The basic 500ml Kit has
a capacity of 6x36 exposure 35mm films. As far as using it, if you can
process B&W you can use the agfa kit for colour. You have a choice of using
it at 30C or at 38C. There are only 2 chemical baths (Developer and
Bleach/Fix). Pretty simple really.
The only thing is - work out how much it is going to cost you. I find that
the off-the-shelf kits tend to not offer very good value over labs, where
you can get process-only done for a pittance. If you buy the chemicals in 5L
lots though it becomes more economical, assuming you use the chemistry fast
enough that it doesn't go off. Of course there is one big advantage in doing
it yourself compared to a lab - no scratches. I haven't been able to find a
lab yet who can process film without getting some scratches on it. For that
alone, I would be prepared to pay more for chemistry than what labs charge.

Thank you very much
Only a last question, are there many differences between the products of
different brands [agfa/kodak/ornano etc etc] or are similar?
In B/W process every developer is different and produce a different film
result for contrast or grain etc etc. In color process is the same?

 C-41 is supposed to be a standard process. All C-41 type processes should
end up with the same result. Some of the chemicals have different times etc.
Some have different steps.

    Nothing to get a head ache over. Use what you can find.

C41, AP70, Fuji etc have the same composition for all practical
purposes.

In theory, all C41 compatible developers should be identical, because C41 is
a standard. In practice there are slight differences between brands, but not
major. I preferred the results from the Agfa kit compared to what minilab
processors churn out - hard to put my finger on the exact difference,
perhaps a little better saturation and a little more contrast.
The good thing about the Agfa kit is that it is optimised for small tank
development. Most of your Fuji/Kodak etc chemistry is designed for use in
auto replenishment processing machines. It should be still usable in small
tank development, but some tweaking of times may be necessary.

equivalent to C41 for color negs.
