As to how I got that skin-tone effect: I really like monotone picturesbecause of their extra dramatic impact -- I find that COLOR monotone picturestend to be more dramatic than grayscale. I recently learned that if I use amuted red as my one color tint and greatly decrease its intensity to a neargray, after a whole lot of processing, the resulting color greatly resemblesnatural skin tones.
The trick is to work in monotone but with the color depth set as high as possible. I put the picture through several filters (usually just sharpen and edge definition), stopping after each filter tomanually smooth all the pixels together, following the newly defined edgesand usually working with a zoomed shot. When the whole picture is smoothedout manually (it doesn't get the same "natural" effect if you just use thesoften filter), it goes through the whole process again, over and over untilthe desired effect is reached.
If the color depth is set at 16 million,after a few few times through the filters, small spots of color begin to popup, other than the one color initially chosen. You know its time to stopwhen a whole bunch of the OPPOSITE color starts to appear (green, in the caseof the initial red) -- for the skin-tone effect, you want to get it JUST tothe point where the green starts to appear -- it gives a sort magical depthto the color and creates the illusion of a full color picture. If you keepgoing, you get very unslightly green blotches everywhere.
