C-41 for red negatives, no brown or orange

[kamakany]

Hello:

Firstable sorry for my English. I’ve been scanning medium format during last year using a Braun fs120, but I’ve discovered that it has difficult scanning c-41 developed negatives. Not with all, ONLY scanning brown/orange negatives. So I have to get perfect c-41 process in order to getting RED negatives. I am using tetenal c-41 (following correctly all instructions, times, etc.).

Left: negatives developed in shop, right: my development.

When the negative scanned is brown or orange when you see the finel image you can find red color over the darks places, and sometimes a blue soft filter over all the image. I found sometimes paralelles lines in the sky as you can see:

Somebody know how to get this red color please? Perhaps using other chemicals?

Thank you very much.

Well, scanning is off topic here, but real quick, your scanning software should have automatic controls for this, with the option to adjust to your needs.

Perhaps post this question at www.dpug.org, our sister site.

Thanks for your answer bvy, but I think that it is more relationated with developing than scanning. It is not about controls because even using it you can't get a good image. I would like to ask about your colours results in negatives for people that work with tetenal c-41.

Thanks againT

Even with good processing the color cast on negatives can vary considerably, depending on the film. On DPUG.org you might find help on how to deal with it. If it is due to bad processing, you will get bad results no matter what.

My scanning software has a color balance tool. Click on the area that you want to appear as gray, and everything else should fall into place. In theory. I would balance against your reddish sky and look at the results. If they're way off, then, yeah, it might be your processing.

But I'm pushing the limits of what's allowed to be discussed here. Again, DPUG.

Color negatives from Kodak and Fuji should be clear and not hazy, and the color should be orange to red. If they are brown or have haze, there is a processing problem. This can be due to one of many things such as fog, bad bleach and bad fix.

If it is the last two, try re bleaching, wash, fixing and stabilizing in new solutions.
