Amazon Prime Photo - TIF files

[User.82148]

I can use Prime Photo with RAW and Jpg files without any issues but although I can upload Tif files I cannot view them. They are supposed to be a supported file. Any ideas or do I need to convert to Jpg first?

That seems odd. How did you make the tiffs? I wonder if they support all tiff features? Have you tried an 8-bit tiff with no layers or compression or other 'advanced' options?

I started with raw files, imported to Lightroom, did some edits, sent to Dfine for noise reduction which then returned the file to Lightroom as a tif file. I haven't checked if the fils are 8 or 16 bit.
