The slides were scanned very good. they showed up in order - as presented in my carousels. However, when I moved them from my Photos (Mac) to an album, they were not in order. After exchanges of emails, I learned that in albums one needs to save them to Sort by Title in order to put them back in correct order. Customers should be told this up front. Slides were put back in carousels in correct order, but not upside down consistently. Not that I ever want to use the carousels unless desperate, but wanted to compare slides to scans on side by side screens. Color corrections. Mostly I didn't need to have this done, because I can do this in Photos on my Mac.
