Unable to open certain images

I have scanned about 15,000 negatives into TIFF files. About 20% will not open in Denoise 2.2.3. They were all scanned with the same scanner, software, and parameters. All open fine in Photoshop, Lightroom, NIK, etc. What could be happening?

Next time choose the correct category for your post.

For a image that doesn’t open please upload a copy to a file sharing site such as DropBox so we can check. You also say it won’t open, what is the message you get?

When you say “They were all scanned with the same scanner, software, and parameters.” please provide details.

Apologies. What is the correct Forum?

I said Category, this is the correct category for Technical help. You can see the category in the pull down to the right of the title when you create a thread.

You used the Product Release category.
