    Thumbnails Grayed Out in Some Modes

    I have followed this forum for a long time and now find I must ask for help.

    I have a desktop XP system that runs LR 3.3 just fine. My HP Vista 32 bit laptop
    has a problem with LR 3.3. I have loaded, deleted and reloaded the software.

    When selecting files, Raw or Jpeg, from a source folder for Import in Library Mode the thumbnails are visible.

    After importing files in Library Mode, thumbnails are grayed out but metadata is active and the file name appears on the grayed out thumbnail.

    If I export a file from Library mode and view it in Bridge it looks good. If I look at it with Bridge, in the folder where LR saves it, it is also good.

    If I switch from Library Mode to Web Mode the thumbnails become visible. If I next go to Print Mode the image is visible. If I go directly from Library to Print Mode the image is grayed out. Going through Web Mode makes it visible in Print Mode.

    Switch to Slideshow Mode and the image is grayed out. In Develop Mode it is grayed out and the Histogram is also grayed out but the R, B, & G numbers change as you move the cursor around the blank image.

    Any suggestions would be greatly appreciated!

    Welcome to the forums, Alans :-)

    What you describe sounds like a corrupt monitor profile. If you calibrated/profiled your display, recalibrate/reprofile, or try assigning a sRGB profile to your monitor in Vista's color management applet if not. Note that assigning the sRGB profile is not a solution, but a step in finding out what's wrong.

    Beat,

    You had the answer. Changed the monitor profile and LR 3 now works as advertized on my laptop.

    Thanks,

    Alan

    Alan,

    Please be aware that using sRGB as your monitor profile is not a solution, but just a workaround (sRGB is not a display profile, but a color space). Using sRGB will make your images show up, but not in correct color.

    You should assign a proper monitor profile, best done by calibrating your monitor with a hardware device. These devices are available from about $100 and are indispensable for somebody working on color, tones and exposures of images. It will also work calibrating your desktop monitor, which probably is even more important, as notebook displays are not very reliable in terms of color/luminance accuracy anyway.
