Step #5: Uses for Online Photo to Sketch (Stencil Maker). A cleanup operation deletes all files approximately every 30 minutes. The images that are both uploaded and the created stencils are stored in a temporary location.

Think of this as line thickness.įinally, when satisfied with your stencil, press the "Save"īutton to save your new sketch or pattern. The "Density" determines how the neighboring pixels are entwined orĬombined. The "Contrast" adjusts the threshold of the white and black pixels.Īs the slider is moved to the left, the background noise is minimized. ![]() Now adjust the "Contrast" and "Density" by dragging Next press the "Upload" button to load your image.

Final touches to make faces and the like look better for shadows and highlights were accomplished by selecting a representative shadow/highlight colour, and adding the extra bits with the airbrush tool (looks like an airbrush). Finished with a completed colour layer ¶Īfter some effort, all the regions get filled in. This is what we see if we set the colour drawing layer to normal mode. You should see the colour darkening as we draw with a colour similar to the background colour. Using a big brush (with the brush tool for more natural edges) we fill in the area of that colour roughly (doesn’t have to be perfect). Using the colour-picker tool (looks like an eye-dropper), we select the colour we want to paint from the original image (just activate the “original image” layer and try to pick a colour representative of an area), and then we re-activate our colouring layer, which is still in overlay mode. Colouring looks after doing one area of the image ¶ We put our original image back in the background, and set the white layer to overlay (as we see here) - this means we can see the coloured areas behind the white layer - this is extremely helpful when we’re painting the white layer, as sometimes the edges are rather fine, or are in the middle of an area that’s more or less the same colour. Images,original image & colouring layer in overlay mode L&C dialog with set-up for the colouring trick ¶ For the colouring, we need some more work (mostly slogging, though). We could stop here, and this is a decent sketch effect. ![]() It’s shown here with a white layer behind it. To do this, open the Layers & Channels dialog (if it’s not open already), and add a layer mask to the layer with the inverted edge detect layer ( Edit -> Copy with the highpass layer selected, Add Layer Mask with the inverted edge layer selected, then select the mask and Edit -> Paste) Since we kept the strong edges in the highpass filtered layer, this means that we end up with a rather nice black-on-transparent layer. Invert the Sobel edge detect (you did keep a copy, right?) with Layer -> Colors -> Invert and apply our highpass-filtered copy as a mask. Small trick to get to black-on-transparent. The only problem is it’s white-on-black, when we want black-on-transparent ideally. Just drag the mouse/pen along the bottom of the curves tool. We set the curve type to free (which allows discontinuities), and then for the bottom 3/4 of the curve (or thereabouts) to 0. The easiest way to do this is with the curves tool ( Image -> Colors -> Curves) like this. To get them, we eliminate the edges with small magnitude. We only want the strong edges, otherwise it’ll look crap. ![]() Curves window for how to do a highpass filter ¶ Equalised & desaturated Sobel ¶īring out detail with an auto-equalise ( Layer -> Colors -> Auto -> Auto-Equalize) of the sobel edge detect, and convert it to greys using desaturate ( Layer -> Colors -> Desaturate). Straightforward Sobel edge detect ( Filters -> Edge-Detect -> Sobel) of original (don’t forget to save a copy of the original) The Sobel edge detect should be done on the background image (without an alpha channel) rather than a copy of the background (which has an alpha channel).
