| Andrew, I think if PE as a brush, and push is how much you move the bristles (not the whole brush) one way, pull is the other way.
(Extremes of either will give you speckles or sparks)
Each of the push/pull can also lighten or darken (and a push lighten does not cancel a pull darken eg pull with +2 is not cancelled by push with -2). I think this is because you could say that different 'bristles' are pushed than pulled...
Over the other side you can factor what part or 'theme' of the image is mainly worked upon, and I see the input tick box as factoring some of the original back in. I've yet to describe the line box properly....
The other bits below are more obvious..
Try setting everything to zero, then just moving one slider, a little then a lot...
Anyone else have any thoughts on this? |
