A quarter of a series of 50 Photoshop files opens black in IV. I have searched for differences between the Photoshop files that open normally and the ones that open black. The only consistent difference I found was that the images that do not open report having large 'original colors' depth: up to 152 bpp. The largest color depth of images that do open normally is 88bpp. Both figures seem very high to me. I can't find any info online about images with such high color depths, 48 bits seems to be the highest normally. Of the images that open black in IV the image information reports that it has 1 colour and loaded in 0 millliseconds.
All the images were originally created (over a several years period) on a Mac and are now on Windows. In Photoshop, both images that open black and that open normally (of this series) report being 8bits. All the files have the .psd extension. Files sizes vary between 1 to 32 MB, but the issue seems unrelated to the file size.
Any clue what could cause this opening black of certain Photoshop files?
Thank you!
