Do you mean to say that it is changing the color caste of the original images on your hard drive?
And when you import the images in Lightroom, it gets corrected?
From where did you get those images on hard drive?
Were they copied directly from sd card or were directed through another external editor?
Would suggest you to make sure the program is updated : Keeping Lightroom Up-to-Date
And also calibrate your monitor profile : How do I change my monitor profile to check whether it’s corrupted?
Thanks for your quick response.
I took the test image on my Canon 700d. Imported it onto my hard drive from the SD card via a lexar card reader. ( But the problem occurs on any image I import).
The original image on the hard drive appears modified when imported into LR. That is it shows with the colour caste in the Library section. When I go to Develop section, the before image has the colour caste. (See the left hand image on the screenshot). But when I switch on the Before and After comparison as in the screenshot, the After image (before any adjustments are made), does not have the colour caste and is the same colour as the image on the hard drive. This can't be right as initially the before and after images should be the same. In fact this problem did not appear when I initially used the program and everything worked OK.
If it is something I have done, surely it would not appear once I uninstalled and then reinstalled the product.
Surely it cannot be a monitor calibration problem as this would affect all the both the before and after views
I will check for updates but can't see that this is the problem.
You have a defective monitor profile, the brownish cast in the histogram also indicates that.
As a temporary fix, set the monitor profile to sRGB, as described below. This should fix the issue, but you should ideally calibrate the monitor with a hardware calibrator to create a profile that describes your monitor accurately.
Press the Windows key+R, enter colorcpl, and hit Enter.
Add the sRGB profile, then set it as Default profile. See screenshot (from Windows 7) below.
Thanks. Changing the profile appears to have worked.
As a matter of interest, before I changed the monitor profile, I turned off User Graphics Processor as suggest on another thread. This made the before and after views in Develop appear the same, but the when viewed in Library the photo still had the same brownish tint. However changing the monitor profile solved the problem.
