How to turn off Colour Correction

[dailysetup]

Hello,

So I've noticed that even after doing Negative Slope Correction using my calibration negatives.  When scanning film, the noritsu software will still compensate colour correction.
Ie. if there is an image with lots of RED, it will add quite a lot of CYAN, which I then need to reduce to bring back to normal.

I am wondering if it is at all possible to turn off Auto colour correction and just have the software start with the slope data they I have entered.

I am using a Noritsu 3502, latest software, S3 scanner.

Thanks,

Lowering the CF (colour failure) value will stop the image with lots of red in it changing to cyan.

0 means no CF correction, the standard value is 80.

Enter the service mode, Menu → Extension → Setup → Scanner Setup → Parameters (Negative) → Service Parameter

You can completely turn off the colour correction by changing the scanner setting from ON to C_OFF,  or for both colour and density corrections to be off set it to NONE.

Hey Dave,

Thanks for the tip. I went in and changed those parameters to CF 0 and Scanner to NONE.

Still, I am gettting the software trying to balance my scanned film.

Any other options I'm missing? I noticed there is Photometrey Function in the Operations menu. Should that be on or off?


Thanks

Here is the sample.

As you can see with the Red scooter, it has added Cyan to the rest of the image.

Thanks

The Photometrey Function is only activated when you select it from the F (Functions) menu when printing. It's not an automatically applied setting.

I believe this is what colour failure is, and this is what the scanner is trying to correct. The scanner does not add the cyan to the background it's already like this in the film.

What is the difference to the scan with the settings on or off? Try a higher CF number like 100 and see if it's any better.

Here's another example. First screenshot is no correction, second image is after correction. As you can see the removal of CYAN in the first frame is fairly extreme. Especially when Ive turned off all the colour correction settings.

And what happens if you turn the scanner back to on, and change the CF value to say 90?

I had the same problem I did everything but it didn’t work
