Colour profile conversion for DxO plugins - beta 1.8.0.486

Recommended Posts

Hi,
the issue of colour profile is well fixed for DFine 2 (many thanks for that!), but it still does not work for Viveza 2.

Hi, I'm glad Dfine 2 is working for you. Are you sure about Viveza 2? I just tried it here and it correctly shows the profiled colours. I did notice an issue with resizing the plugin window smaller (the preview becomes desaturated) which I'll investigate, but the colour profile was still applied correctly.

Here in Viveza 2 colors are washed out and have a purple cast.

No luck here either on widows 10

I tried both Tiff and Jpeg files., some show the right colors zoomed in at 33% others not until 100%

Either way, not workable as it is (yet)

With the free Google Nik plugin Viveza 2 I need 100% zoom to get correct colors for 16-bit tiff files. For 8-bit tiff files and jpeg files 33% zoom are sufficient to get correct colors.

I confirm that the colors are not the right ones in Viveza 2. But it's strange because in the magnifying glass they are correct, as you can see on the screenshot.

Hi,

I seem to see a difference in behavior of Viveza when called from AF or PS.
It is true that when the image is 100%, the colors are good but it is no longer usable, while everything is fine when the call is made from PS.
In addition, I noticed the appearance of a button "Brush" when Viveza is called from PS, button that does not appear when the call is made from AF.
How to explain this difference in behavior?

(In the screencopy of PS, the image is without cross processing ...)

It dosn't work in AP, because the brush is part of the Selective Tool, which needs PS scripting. Well, you can create simply a mask or try these macros...

Hi IndigoMoon,

Thanks for the link but the macro does not work with the latest version of AF Photo.

The real problem is that of colors.

I'm on Windows 10 and using the Google NIK plugins.

I've found the following:

In order to keep coherent as much as possible I've experimented with two different size images (.jpeg) I upload to my website - 2500px (long side) and 3000px (long size) - both 8 bit, sRGB, 96ppi*.

#1 - 2500px images. No colour issues whatsoever with the default magnification in Viveza (APh 1.8 beta).

#2 - 3000px images. These images have to be zoomed to 33% to obtain accurate colour.

Now here's where the fun starts ... If I upsize the 2500px images to 3000px there's still no colour issues (default magnification in Viviza) nor are there any issues if I convert to .tiff .psd etc or convert to Adobe RGB.

However if I convert the 2500px images to 16 bit then I have to zoom to 100% in Viveza.

I no longer have installed any Adobe product so I've been using Viveza in Gimp. There's no colour issues whatsoever at the default magnification -  16 bit, pixel size, file format, ICC etc.

Here's the NIK python files from Gimp. They're open source (as spelt out in the files). Perhaps they may be helpful to the Affinity dev's?

[* dpi/ppi not important as it's purely for print and/or screen output - 2500 / 96dpi = 26.04 inches and 2500 / 300dpi = 8.33 inches]

All exe files of the Nik plugins work standalone without color problems. The python script in Gimp for Viveza calls Viveza 2.exe instead of the plugin file Viveza2.8bf. That's the reason why there are no color problems with Viveza in Gimp.

Thanks! 

I have no idea (obviously) how code writing does its business.

So, is there any reason why the Affinity devs' code can't call .exe instead of .8bf?

Surely (?) that would sort out these current issues with Viveza (considering there's no issues with Gimp).

Hello,
the use of .8bf files is the reason for being compatible with Photoshop plugins.
That said, launching the .exe would not be heretical, that's what Lightroom does ...
