Some filters are having negative effects

Hello,

Currently having issues with Diffuse Glow and sketch filers.

In Diffuse Glow, instead of brightening up the picture by placing whiter spots, it places dark spots (like it has gone in reverse).

The same for some of the Sketch filters (chalk & charcoal), where darker parts have gone white and lighter parts dark.

I don't think there is a preference for changing this, as I can't seem to find any.

Anyone have similar problems?

These filters (and many others) use as a starting point your background and foreground colours - if you have reversed them and white is now the foreground and black the background it will have this effect. Just hit "D" to return the foreground and background colours to their default and the filters should now work as expected.
