Desaturate the image
for a cleaner finish
Next, open up the HSV/HSL (hue,
saturation, value and hue, saturation,
lightness) filter and pull the
Saturation tab all the way down to
-100. Desaturating your sketch will
help get rid of any additional colours
that the scan has picked up and
provides a sleeker finish to your
refined pencil sketch.

Select an airbrush
To clean up any dust or
unwanted sketch lines from your
image, create a new Paint layer and
select a f luffy brush: I used Airbrush_
Soft for this. Set the fill colour to
white. Using an airbrush will ensure
you don’t add any harsh lines when
painting over your image.

Painting over dust and lines
Zoom into your image and begin painting over the dust or eraser marks that your scanner picked
up, as well as any unwanted sketch lines on your drawing. Depending on your desired result, you might
want to leave some of the sketchier lines in the image, so only remove the dust if this is the case.Workshops
You can also use the Desaturate filter layer if you
don’t want to use the HSV/HSL filter.Remove any messy lines to give
your sketch a professional finish.
