Turning a photo in to a sketch is easy enough. But what if you want to turn part of an image into a sketch. That is easy too.
We will be using this free stock image. You will find it here
It belongs to *GlamourousAcid-Stock
Step 1 : Duplicate the Background layer by pressing CTRL+J.
Step 2 : I have extracted the figure of the girl from the background and put it on a separate layer -- Layer1 copy. You can use the Magnetic Lasso, Pen Tool or the Quick Selection Tool to extract the figure.
Step 3 : Press CTRL+J to duplicate Layer 1 copy to Layer 1 copy 2. Then desaturate it by pressing CTRL+SHIFT+U.
The image looks like this. Only the girl is desaturated as we have cut her out of the background.
Step 4 : Press CTRL+J. Layer 1 copy 2 duplicates into Layer 1 copy 3. Then press CTRL+I to invert the image.
The girl looks like a negative.
Step 5 : Change the Blend Mode to Color Dodge.
The girl turns white.
Step 6 : Go to Filter>Blur>Gaussian Blur.
Step 7 : The Gaussian Blur dialogue box comes up. Drag the slider from the left to the right slowly changing the Radius. You will get different effects for the sketch. Click OK when satisfied.
This is how the sketch looks. You are done.
