The attached file illustrates the difference between a couple (so-called) 'pencil sketch' (or some might say charcoal or chalk) effects.
Image/Method and/or Comment
* Top Left/Original image for the sake of comparison
* Top Right - Photoshop Sketch/Photocopy filter (settings: 24/5) + a Levels adjustment layer for added contrast.
* Bottom Left - Generated using the method Lisa posted from the About.com Graphics forum in which one step calls for converting the image to Grayscale. (See the
Realistic Pencil Sketch thread just before this one. The results are a definite improvement over the vanilla Photocopy filter.
* Bottom Right - This was an
"accidental art" discovery. (The layer-by-layer sequence and settings can be seen in the screenshot of the Layers palette included in the attachment.)
I found it interesting that sandwiching the middle desaturated, inverted, blurred with two
color layers seemed to yield more skin tone detail than the other methods. I topped these layers with a Channel Mixer adjustment layer for the Grayscale look and a Levels adjustment layer for contrast tweeking.
While the last two methods are Photoshop specific, from what I've seen of other applications like Paint Shop Pro, Photo Paint and PhotoImpact it appears they could be ported without a great deal of difficulty. (Easy for me to say.)
To me the results of these methods provide base images. Additional possibilities might include "patch up holes," adding texture (Texturizer? Angled Strokes? Crosshatch? Colored Pencil?), apply a little blurring here and there (Gaussian? Dust and Scratches? Smart Blur? Median?) and/or adding color where desired.
I look forward to seeing other "Photo-based Art" methods described in this forum.
A
big thanks to Doug Nelson, our site Webmaster, for making this "new playground" available, especially to wannabe-artists w/o a lick of native drawing skills, like myself!
