The following plugin started as an 'inverse' or 'negative' plugin - well - it can a lot more than just that - it has stacks and stacks of colour effects. The following controls are discussed as is, they might change, they might not even work as stated... anyway, a mini help to follow. Some of the combos will not kick in unless other combo values are set, likewise some controls will not kick in or sometimes one control change will basically wipeout the other control resulting in zilch change to the image. Double mix etc. appears not to do much but change some combos and settings and then ... a whole universe of experimentation.

(R) - The red channel negative effect - (R) - source is applied as the input to the red channel

(G) - for the green

(B) - for the blue

R checkbox - active channel - if set to zilch then the red channel will be unaffected

G - as above

B - as above

Inverse Input combo - different inputs - basic input first but after that various averages etc. and 'shifting sands' which basically is used to kick in the third combo and a number of the f(x) etc. controls

Output Mode combo - nearly the end stage of the output - how the source is dumped back onto the screen - not totally true as various mixes are applied afterwards and the grey checkbox is applied on completion.

'Bottom Right' combo - this applies various direction effects or such effect as emboss applied to the inverse effect or the source and then inverted and even an emboss effect applied as the source to the emboss, ok, messy!

Mix R - how the red channel is mixed into the output

G - as above for green

B - as above for blue

Add src - if you set the first to 0 then nothing will be applied. If you set it to 100/100 say then source is added into the image totally - any other factor of application can be set to vary the effect

f(x) and f(y) - applied to shifting sands or shift etc. effects - shifts the image up and down or shifts the input and then applies - a whole range of effects are possible but it is also possible to obliterate the picture. Some of the radial effects etc. need high settings and other effects such as the basic directions work best with low settings

RSrc - some more additions and subtractions to add additional effects

GSrc - as above

BSrc - as above

Rnd - add this random value into the image to get a grain-er inverse effect

Grey - basically average the channels on output to get a greyscale image.
