I am using Capture One Pro 10.2 on a 13-inch 2015 MacBook Pro. Recently I output some black and white photos as TIFF files and sent them to my usual lab for printing. (This was, however, my first time transferring them photos in TIFF format.)
When I got the prints, I noticed that every single one of them had a small thumbnail of the same photo on the upper-left corner. This was unexpected and unwanted and at first I thought the lab had something to do with it, so I contacted them. They replied that this was a problem with the TIFF format and that it was also possible that this had to do with the software I used to output the files (i.e. Capture One).
I should state at this point that I do not see any such thumbnails when I open and view the TIFF files on my machine.
Having googled and recalling that TIFF is a container that can hold many items, I had a hunch that these thumbnails might have had to do with the metadata that was being embedded in the files during outputting. I then stripped the metadata – by unticking all the boxes in the metadata tab of the process recipe – and re-sent the lab one example file for printing. I got it back today and it still had a thumbnail at the corner.
I really want to get rid of the thumbnails, but honestly don’t know what to do next and would appreciate any help/insight on this matter.
For reference I am attaching an example print. The colour cast is from the light source.
