As several others, I have for some time been experiencing problems with black thumbnails in PSE4.0 Organizer when working with TIFFs. I have found a couple of workarounds that may be useful to others.
I have a workflow where I convert RAW files from my Konica Minolta 5D using Camera Raw, and save them as 16bit TIFFs with the Adobe RGB profile attached. This gives a black thumbnail in Organizer every time. 8bit TIFFs also fail. If I save as a JPEG, there is no problem. My Colour Settings are set to ‘Optimise for printing”, so images without a profile get the Adobe RGB profile. It makes no difference if I set the colour settings to “Optimise for computer screens” to default to sRGB. I have also tried updating to Camera Raw 3.4 without luck.:(
I’ve found that there seems to in certain circumstances be a problem with how a colour profile is embedded in a TIFF by the Editor. Sending an image from Camera Raw is one situation, but other people seem to have other scenarios too. A profile does get attached though, as I can open a ‘black thumbnail image’ in the Editor and it displays correctly. Also, the image properties list the profile.
The workaround for the Camera Raw scenario is as follows:
- Transfer the image to the Editor from Camera Raw as normal by clicking ‘open’.
- Remove the profile attached.
- Apply the desired colour profile
- Save the image
The main point is reapplying a profile, so this may well cover other scenarios too.
The alternative workaround is to disable colour management, but that is often not desirable.:)
