It seems the tone is not fixed up by the postprocessing.
A searching map for nearest stipples:
3085 stipples with P(10,10,0.1,15):
size = 0.5 * d *(255-avg)/255-- d is the distance between the nearest stipples.
size = MIN+(Max-min)*(255-avg)/255
Secord's result
I wrote this comment before but it seems to have vanished.
ReplyDeleteThe sizing does seem to have improved things. Two suggestions.
First, it is unlikely that the parameters are right the first try. What does it look like with 1.5 instead of 0.5?
Second, it may have been a mistake to include d in the size calculation. Maybe it would work better with just a standard size and then base the actual size on the average darkness within the area times the standard. Not sure about this one, since it might still destroy structure.
