Cosmetic Correction: Pixel Math does not invert the Hot Pixel defects map

Max

Hello Adam, I am following Cosmetic Correction lessons step by step and have an issue when I should convert the defect map using "Pixel Math". In my case Pixel Math process fails when applied to binarized  hot pixel defects map showing the error you can see in the  attached picture. So I tried to invert the map using "Image - Invert" but no hot pixels were removed after following "Defect Map" process was applied.

Any suggestions?

Best

Hi Max,

I am looking at your expression. You have an "S"... but in Pixel Math the dollar sign "$" is a special character.

So you want to do ~($T) .

Let me know if this is the issue.

Thanks,

Adam
