Default Sketch Effect

This tutorial is quite a famous one. My friend taught me this (and by friend, I mean a professional from england who I met from the net)

*Make sure you have your layers pallette open, if not, click Window>Layers


Step 1:
Open your image. This works best if there is not much of a background cause it spoils the whole "someone sketched me!" line. Portraits are best.

Step 2:
Duplicate the layer by clicking Layer>New >layer via copy or by pressing Ctrl+J.

Step 3:
Desaturate the image by Going to Image>Adjustments>Desaturate or by pressing Shift+Ctrl+U.

Step 4:
Next, duplicate the newly created layer (might be layer1 or background copy 1).

Step 5:
Invert the layer image by going to Image>Adjustments>Invert or by pressing Ctrl+I on the keyboard. Make sure you have your second layer selected before doing this.

Step 6:
Now in the layers pallette change the blend mode to "colour dodge". The image may appear blank but don't worry.

Step 7:
Apply a Gaussian blur by going to Filter> Blur> Gaussian Blur. Start off with a very low value and slowly increase till the desired value. Do not increase too much because it will make the image look photographic.

Alternative:
You can also create a colour pencil effect (the pictures you saw in those story books when you were a little kid of just 8)
All you have to do is:

After step 3, skip step 4 and then continue with it. You will get a nice colour effect. works with group pictures also.

here's my image:



Well I know its a bit on the freaky side, but I have a good excuse. 70s day at college and I am caught in action.

Puzzling. Gaussian Blur is not such a resource hungry filter like the radial blur. Maybe you should try resizing your image. A large image with a rez of 2048*1536 might, (just might) cause a system hangup. Otherwise, dunno what to say.

Till about six months ago, I used to run Photoshop on a 192 MB RAM system (100Mhz) and worked fine for me..

@ ramprasad: it should work. at least, you can try! When I say that I use photoshop CS, doesn't mean that the earlier versions are inadequate in any way. Photoshop 6 is just as powerful. its only that CS has a few more features (like healing brush, layer comps, filter gallery, file browser) otherwise, Photoshop away!
