Colour Shift - Extremely Strange Problem !?
I have 2 x PC with switching box - one monitor
Just calibrated monitor, very little (if any) change since last done
5 image HDR converted to JPEG - wish to print A3 ( had profiles done always)
I selected photo from large thumbnail - it looks fine
Double click on thumbnail to see full screen - photo - huge red shift
This only happens on 1 x PC !?
Can anybody PLEASE give me a clue as to what is wrong - graphics card ? Me ?!
It is fine on 2nd PC
Surely if it was the graphics card, the thumbnail would look bad too? ...................
Thanks for any welcome help
Make sure the monitor profile created is V2 and matrix and NOT V4 and LUT, also make sure the program you are using to visualize the image is FULL color managed.
Both PC's has to be using the same calibrated profile for monitor.
Same settings within OS and software to all used color management related options.
thank you both for your replies - I am struggling
Thumbnails look okay, but double click into Miscrosfot Viewer or any other way of viewing them large and the colour is way out, contrast is too high as well - they look terrible - all photos
This has only just started.
Could it be the grphics card in one of the PCs is faulty ?
There are so many settings in control panel - colour management etc. - I do not know where to start ?
Several software is "color blind" as it is not "color managed".
Mistakes also can easily be made by image processing in not "converting" color spaces to another color space, but by "assign" a (wrong) specific profile.
In practice many mistakes are made by:
- Adobe RGB files looking into an sRGB space -----> giving dull and "washed out" colors.
- sRGB files looking into an Adobe RGB space -----> giving over saturated colors, specially red.
Not to speak of "Wide gamut" color spaces.
To much involved to give a simple answer. It takes some time for "study".
It has not to do with the functionality of a graphics card.
It is system, and software related by color management.
Thanks for taking the time to reply
I do understand this up to a point
Windows Explorer - JPEG - Large Thumbnails - look okay
Double click to almost full screen - Windows Photo Gallery - definate red & contrast shift
View same JPEG in Nikon Capture - okay
View same JPEG in QImage - okay
What is going on ??
It is as if Windows Viewer has it's own colour space ? - but of course as I can see them full screen using it, it is what I use to decide I like (or not) before prinitng ............
Tried booting in Safe Mode - no "odd" programmes running.........
Windows viewer from XP is not color managed, from 7 is but not compatible with V4 profiles...
A big thank you to you all for pointing me in th right direction
It turns out that somehow ??? the default setting for th monitor was a paper profile??
Changed it back - Hey Presto !! - Just printed 70 pics - FINE !!
