Irfanview, color management status?

[CAcreeks]

Irfanview's Options > Properties/Settings > Zoom / Color Management dialog has a checkbox for enabling color management, probably ICCv2.

Once enabled, the default is to use the Current monitor profile, but I found a DCI-P3 color profile from Apple and set it as the Custom ICC/ICM RGB profile. So far I don't see any big difference either before or after, maybe because I don't have a P3 capable monitor.

Can anyone give me a quick summary of how to use color management in Irfanview?

It's pretty clear what to do in GIMP, but I'm baffled by the Irfanview interface. Thanks.

Don't do it!

You can configure IrfanView to apply a color profile and it works.

However, if you save the image, the saved copy will have that profile applied to it.

Then, of course, the profile will be applied a second time when you open the saved image.

IrfanView just has a single buffer. It really needs one for the original image, and a second for the transformed image with the display profile applied.

Thanks for the advice. I seldom use Irfanview to edit and save an image, but when I do, I'll remember this!

Is the color profile inserted in saved images only when Custom ICC/ICM RGB Profile is selected, but not when Current Monitor Profile is selected?

Looks like Irfanview 4.36 supports both ICC v2 and ICC v4. With Color Management enabled and Current Monitor Profile selected, it shows both the cyan and the purple patch on the following web page (after saving to disk). With Color Management unchecked, both show as gray.

FastStone displays both patches as gray, but I don't use it enough to know how to enable color management, if available.

It seems to apply the Current Monitor Profile if you have the default setup in Control Panel | Color Management. I just checked it here with Win 7 Pro and IrfanView 4.42.

If the image doesn't contain a color profile you can tell IrfanView to assume one (typically sRGB).

Thanks again. Here's a post from 2013 that I did not recall until Google found it:

So it seems Irfanview can be used to view, but neither edit nor save, non-sRGB images on a profiled wide gamut monitor.

FastStone 5.5 supports ICC v2 and v4 profiles if enabled, but shows correct colors in preview thumbnails only if the were generated after enabling CMS. As far as I can tell, it lacks support for wide-gamut monitors.

Thanks for that link; from malch's post I was wondering if I'd mis-perceived how IrfanView color management worked, since it seemed to be properly displaying my test TIFF with an embedded wide-gamut profile.

I hadn't tried editing or saving in IV, just viewing. I'll remember to avoid that when I have occasion to work in wide-gamut.
