Lunacore Photoshop Training - Photo to Line Drawing tutorial ~ Photoshop Tutorial

Open an image that doesn't have a lot of rough textures, because like with the other techniques the results are not going to be that good.

In my example I've opened the image of a clock in Photoshop.

Original image of a clock

Duplicate this background layer by clicking on its icon in the layers palette and while holding the mouse button, drag and drop it on the Create a New Layer icon .

Duplicate Layer

First press Ctrl + D (Command + D on the Mac) to change the foreground color to black: Fore- and background color

Select in the menu: Filter / Other / High Pass

Select a very small radius. The radius depends on the size of the image. In my example I've chosen a radius of only 0.3 pixels.

Result of High pass

Just make sure that you don't use too much radius like in this example:

Image with too much High Pass applied

Select in the menu: Filter / Sketch / Note Paper...

Use the following values:

Image Blance: 25 (depends on the image, experiment)
Graininess: 0
Relief: 0

The result looks like this:

In our previous step the lines are not black but some shade of gray. We can change this by adding a threshold correction.

Select in the menu: Image / Adjustments / Threshold...

Move the slider to the right until you see a black & white drawing of the image. In my example a Threshold Level of 180 was enough.

Here's the result:

Concerting gray lines to B&W

Go to the tool bar and select the Pencil Tool and set the foreground to white by pressing X on your keyboard (this switches the fore- and background colors)
Now remove some a the few distracting pixels by clicking on them with the pencil tool. Make sure that you zoom in and that you use a small sized pencil.
