very nice, guys
most of my filter forge filters have been done on a sort of hunt and peck, plug 'n play type basis. i understood some things but a lot was just trial and error and see what comes up, then publish it.
this is the first filter i've constructed where i really felt like i was constructing it; that i knew what i was doing and had a distinct direction i wanted to go in and went there.
it's a sort of luminosity mask filter. i copy out part of the luminance values and send them off one way, alter them, and then bring them back to the main program line. that gets mixed with something else, and voila', a luminance filter.
so, here's some results of that. bear in mind that this was also primarily designed to work on portraits, not landscapes. but nonetheless, it shld work on just about anything. it was also designed not quite as much for photo art as for photo correction and balancing, but there's enough variety to it that it will work for art also
also, because i'm working mostly with luminance here, this makes it pretty easy to get a number of different black and white looks.
