Never used C41 myself, but it should work fine.

Indeed it is good for B&W C-41 films. I've personally used it and it gives great results.

Thanks guys
I have heard that c-41 does not accept
Temperature difference, even if one degree + \ -
or +5sec on dev or blix As an example

Is it accurate to this degree ؟؟

 

[Ottrdaemmerung]

No. Temperature and time need to be as tightly controlled as you can get. But if it was as sensitive to such a fluctuation as you describe, it wouldn't be possible to do it at home. Actually, many people leave the film in the blix for longer than the specified time because they believe that blix doesn't bleach and fix as efficiently as separate bleach and fix chemistry.
When you buy the Unicolor kit, it will give you all the directions you need.

Nah. +/-5sec is simply called very slight pulling/pushing. People do it on purpose, you know. Temperature variations may cause color cast or crossover, but it's really not as bad as some try to make it sound. It's more important to be consistent from run to run. By the way, when processing B/W you don't care about color do you?

With that kit, development is normally 3:30 at 39C but a one stop push is 4:40, two stops is 5:50 so it isn't that sensitive. The temperature can also vary a bit without ruining it. You can adjust for the difference when printing.

Blix finishes to completion so you can blix for 6:30 at 39C or 8:00 at a lower temperature if you wish and it will just go to completion. I don't think you can blix for too long. As I reuse my kit A LOT I blix for longer, after 24 rolls I blix for over 7:00 to be sure.

Chromogenic B&W films will work fine though honestly for home development you get more control with conventional B&W films, easier to print too. Just my opinion, I used to shoot a lot of chromogenic B&W when that meant I got 1 hour service at the lab but now that I do all my own developing I do C-41 color and regular B&W when I want B&W.

Thank you guys


I have an idea (I dont know Is it true or not)

I think to shot 6 images As an example

And cut negative thin pot it on tank and test my self with developing (not loss whole film with testing )
