I have been using PDN, Lightroom and Topaz Denoise to edit my wildlife photos for a long time. I use three screens, with an app open in each of the three screens.
Something appears to have gone slightly amiss with the most recent PDN update from a colour and vibrance perspective, which is clearly noticeable when looking at the same image on all three pieces of software on all three screens simultaneously. I have taken a screen dump of all three images, and reduced the quality significantly to fit into this post, however, the difference is still very noticeable:
PDN:
Lightroom:
Topaz Denoise:
The loss of colour and vibrance is quite obvious on the PDN screen. The same end result regardless of which monitor I look at!
Nothing has changed on my computer, everything works as normal. Quite simply, as soon as PDN was updates to 4.2.15, the above result occurred immediately. Note that the edited image doesn't change, it is merely the screen visual that changes. If I adjust the contrast or the brightness on the image in PDN, these changes are reflected on the images in all other apps, although it is impossible to know what needs to be changed or what has been changed if looking at the image in PDN.
Cheers,
Rob.
