As
a child, I did my fair share of coloring, first with crayons and later
with colored pencils and ink markers. Unlike at least one friend
(shout-out to Eva of Dawn and Dark Ivory fame), I didn't grow up to be an artist, so I haven't done that sort of thing in quite some time.
Instead,
I wound up with careers in other fields, and in one of them, I've
lately gotten to the point where I occasionally get to visit schools and
talk to kids about what I do, how it relates to things they're
studying, and all that. And so, I've developed an interest once again in coloring pages - but this time, from the side of creating them!
Conveniently,
I take a lot of photos of things that make interesting subjects for
coloring pages. Inconveniently, I don't have a light table and
parchment paper, which I'd instinctively want to use to trace the
outlines of things in a photo to create a coloring page. I do, however,
have Photoshop. But knowing how to use Photoshop to process photos is
one thing, and knowing how to use it to create a coloring page from a photo is quite another thing altogether.
I
was well aware of the various filters available in Photoshop for this
sort of thing. I could "Find Edges." Or, I could create "Glowing
Edges." Or I could "Trace Contours," or "Emboss." So many choices! A
tutorial video online suggested instead creating a greyscale image,
duplicating the layer, setting the top layer to "color dodge," doing a
gaussian blur, and adjusting the blur ratio. I tried it, but found it
to be a rather complicated manual way of arriving, more or less, at
"Find Edges."
Then I ran across a page
suggesting the "Photocopy" filter, with its sliders for "Darkness" and
"Detail." Aha! Photocopiers, I could handle. (Fax machines, less so.)
I gave this a shot, then went in with a white "pen" to tidy up the
image, followed by a black "pen" to strengthen some of the lines - steps
which have to be done after using this filter - and in an
acceptably short amount of time, actually had something I can give
schoolchildren to color. Hooray! Here's a scaled-down version of the
first coloring page I've ever created.
The Subaru Telescope and its adaptive-optics laser.
I
intend for this to be just the first of several, perhaps even "many,"
such pages, now that I've found a practical and reasonably quick way of
creating them.
