Negative lab pro convert problem

Hi,

I am using negative lab pro trial v2.1.2 with lightroom classic. Once I hit convert my photo stays negative. Can anyone help me with this problem? Using mac os x 10.15.6

First, make sure you are hitting “CONVERT NEGATIVES” and not the “APPLY” button… some users will mistakenly hit the APPLY button before they have converted, in which case, Negative Lab Pro will basically just exit without doing anything.

If you hit “CONVERT NEGATIVES” and it appears to be working, but then when it returns to the plugin, nothing has changed, make sure you are using the latest version of Lightroom Classic.

Thanks for the reply. My lightroom cc is up to date, 9.4. And I am hitting convert instead of Apply.

Hey,

I am hitting convert and using the latest version of lightroom cc.

Hi,

I notice in the bottom right of your screenshot, there is a smaller window where it appears that it has been converted properly.

Also, curious if you see it appear converted if you start moving one of the sliders in Negative Lab Pro, or by switching to a new window, and then switching back. If either of these makes the image appear correctly converted, then it is likely an issue between Lightroom and your graphics processor. In which case, turning off graphics acceleration should fix it (go to “preferences”, then select the “performance” tab, and turn off any graphics acceleration).
