Many of the images are orginal - set to "As shot". I'll import a new raw as test. Pleae bare in mind that I did a sucessful export from these crappy looking raw thumbnails wheich were just fine. Thus it can't be extreme development setting or the camera raw driver.
Get did a new import of one cr2 (raw). The preview on the Import screen looked fine BUT the imported images is bad - both in Development and Library...
THis has to be a LR setting of Version 4 bug!!!
You said that everything looked fine before replacing the motherboard, that takes the posibility of an LR bug out of this equation.
Did you replace the motherboard with the exact same model? If not, have you reinstalled your device drivers?
That new screenshot of LR helps. We can see that the white point is entirely off just by looking at the histogram, instead of displaying as grey, it's displaying as pink. Lightroom is a color managed application, I don't know about ACDSee, but I doubt it. What profile are you using for your display? Have you calibrated your monitor?
PS has the same problem. The MD was replaced to fix a bootup problem; Don't know if there was a version update.
Maybe you're right about the diver - but why then is Windows and ACDSee ok? Is there a way to update the driver in LR and PS?
Maybe I need to reinstall - had to go there though
Photoshop is also color managed. This means that are affected by your monitor profile, while non-color managed applications are not.
Drivers are software that control hardware. Software, like LR and PS, do not have drivers.
Reinstalling is not going to fix this.
You need to disable the monitor profile you are using.
I've removed and recreated the monitor profiles but no change. That seems to be on the right track though.
I'm stuck at this point. I guess the only option let is to call adobe.
Thanks for your efforts though.
When I rebooted this morning, I had a Windows Update notice. One of those pending updates was for NVIDIA, So , after the update and reboot it's workingf fine now.
In conclusion; It appears that the GPX 470 driver had to be updated and patched by Window 7 in order to work properly with the new Motherboard.
Thanks for all those who contributed to this fix!
