@priort @kofa @ggbutcher @Matt_Maguire, I really appreciate all the replies and advice given over the weekend and that really cleared up the confusion I had…
@ggbutcher thanks for sharing the article that you wrote, it’s very informative and I learn a lot from it
So just to summarize and conclude in case this will be helpful to others, basically in DT, it’s important to use the correct monitor profile for the display profile. Using the incorrect profile (such as ‘sRGB’ in my case where display that can cover wider color space) would result in the overly saturated looking pictures because of the colors are not mapped properly.
The issue I thought I had with jpg exported with sRGB color space looking much more saturated, it turns out that I have erroneously thought Irfanview was showing me the correct views, but it seems the images were not displayed in the correct color space. Thanks @priort for pointing out this issue.
I have then used both DT and Krita to view and compare the jpgs and voila, the jpgs look OK with very little difference in color, definitely none of the over saturated look. In fact the jpg with sRGB color space is to my eyes, identical to when I used soft proofing function in DT with sRGB profile.
Thanks again to everyone for helping me clear this confusion that’s been bugging me for quite long now!
