Appreciate the comments from you all.
I should have stated this is the PC version.
All pics are on the same CF card in the 7Dmkii. usually full RAW, some are Med Raw (as Canon calls it)
The Luminar tech support has been responsive, they have suggested some things to check, several
Microsoft files that they wanted to be sure I had the latest version.
I have uninstalled luminar several times and several computer restarts.
Most recently I took several pics and in RAW and downloaded them to my desktop and opened them in Luminar,...no problem.
Need to try more pics.
The previous RAW files that have been corrupted were first downloaded to the desktop and then to LR 5.
Then I opened the files in Luminar. Those are the ones that get corrupted. As I said before,
if I then save the file in LR as a jpg, then open that file in Luminar, no corruption problems.
I will try to attach a file that is corrupted it shows as a jpg, need to try to find the cr2 version.
Will see what I can do Dave-Bass5
Viewing and even working on a CR2 file in Lr is a read only operation, as it should be for any other converter except DPP. The image that you see on screen when in the Library module is also a JPEG, one of the ones held in the My_catalogue_namePreviews.lrdata folder structure.
Lr will write data to a file on occasion, you can get it to write certain EXIF metadata fields to the actual file, instead of just holding them in the database. That can include the text list of edit settings for those file types that will allow that, .dng springs to mind for RAW formats, and JPEG and TIFF for RGB files. To get Lr to do this though you have to specifically tell it to, especially with a CR2 file.
If the files are still in the location that you uploaded them to, and they still work fine if you do something other than just view the image in Lr, I would try exporting them again because if they export OK it will require Lr to actually read the file to complete the operation, then there is nothing wrong with the data in the file. If opening them in Luminar is still causing problems I would be looking at Luminar, not Adobe for the cause.
You could also download RawDigger, which is a really good RAW file analysis program. I would trust it to show me if there were any data corruption in a RAW file.
