colorcast when importing dng file output from on1 nonoise ai

Getting blue color castwhen importing dng file output from on1 nonoise ai
 

[Subclavius]

Hello @manjad and welcome to the forums.

Are you able to give any more details about the problem or attach the file in question?  When you refer to the blue colour cast, do mean that is it blue when compared with Lightroom/Photoshop for example, or compared with a previous version of Affinity Photo?  Do you get the colour cast with any other files?  Does it still appear, for example when you turn the lens correction off?

[RichardMH]

Did you do the raw processing in affinity or nonoise? In any case by importing it into the develop persona it is being processed again. Maybe turning off the Tone Curve, Noise Correction and Exposure Bias in Develop Assistant would help. Might be worth exporting a tiff from nonoise and seeing if it still happens. I use Topaz denoise as a plug in. Pretty sure you can use nonoise the same way.

Hi

This reminds me of a colorcast mentioned on this forum about DX0 pureraw.

In the meantime,

I had read on a Darktable FAQ that this kind of problem (pink or blue color) was induced by screens which are not all able to translate fine variations of range in the highlights and that each software had its own way to deal with this limit
From memory Aurélien Pierre advised to limit the range about 230

On your histogram we can see that the high limit is largely exceeded, which should not be too hard to correct

In Develop basic
              Reduce the exposure a little
              Decrease the brightness
              Play with Shadows and Hightlight
              Interactively
First try
to get close to the limit without exceeding it and conclude     the interaction with the 2 softs with your screen
And tell us, please

You running the latest update of nonoise? They have a fix for a colour cast problem.

Posted an updated version of the post with comparision , here
do not know how to delete post

AP 1.10 (windows store edition) on Windows 10
Processing image in on1 nonoise ai as standalone and importing the resulting DNG files in AP
causes images to look overexposed and/or with colorcast all the time.

no other adjustment was done as other than noise removal and sharpening in On one Nonoise ai

opening the same DNG files in PS elements 2020 works fine.

same dng file when opened in ps elements 2020 retain highlights whereas even after reducing exposure and adjusting the higilights in Ap the highlights loose a lot of detail.
here are screenshots of the same file at zero adjustment in both AP and PS Elements 2020

refering to acdsee which shows the embedded jpg files from the raw files and same file when opened in PS elements 2020,
On one nonoise ai only allows to remove noise and sharpening, no other adjustments were made, the blown highlights are a bigger problem,
even when lens correction is disabled

Probably because you have created a new forum account (mjad) rather than using your old account (manjad).

@mjad What happens to the picture when you press the 'Develop' button?  Is the colour cast/blown higlights still present?  Only when the picture is developed does APhoto assign the destination colour space to the image so the colours/highlights etc may then change.
