Issue with High Pass Live filter...

Recommended Posts

Last night I was attempting to perform a High Pass sharpening routine using the High Pass live filter when I encountered a problem setting the filter to the Vivid Light blend mode which gives me the result below...


If the live filter is set to any other related blend mode such as Hard Light or Linear light this does not happen and the image looks normal and sharpened as expected.  Furthermore if I leave the live filter blend mode as Normal and set the associated image layer to Vivid Light the image again looks as expected with the desired sharpening applied.

I checked to see if this was perhaps associated with the file source (Nikon NEF) but saw the same issue with a Canon CR2 raw as well.

Is this a bug?,  I don't think I've done anything wrong...O.o

Hello @El Sid,

I think so, that's it is a Bug.
When the high-pass filter is used normally, the Blend Mode vivid light will also work.

I think this bug is affecting 16bit or higher. If you convert your image to 8 bit the High-pass filter with Vivid Light blend mode works, it fails on 16 bit.
