Deke's Techniques 428: Auto-Blending Different Depths-of-Field in Photoshop

Blending Different Depths of Field in Photoshop

In this week's free Deke's Techniques movie, Emperor Photoshopus Dekian shows you how to blend two different depths of field, taken from a museum display case at the Roman Baths in the aptly named Bath, England. The result is the in-focus revelation of both the text in the display, and the coins that are the real focus of the exhibit. Tangentially, it will also make clear Deke's love of all things Ancient Rome.

In the video, you'll see how Deke uses Photoshop's ability to stack and blend layers to mix the important information from this placard, that was placed at the back of the display case:

With this detail from Phillip and Otacilia's coins that were mounted on wires coming to the front of the glass:

To create this composite, in which all the important details are in focus (and some atmospheric bits still retain their original depth of field:

Check out the video to see how Emperor Deke fine-tunes the process (and thereby saves you some trial-and-error of your own). And if you'd like to check out other treasures from the museum of Deke's Techniques, you can get a free 10-day trial at Read more »

Deke's Techniques 659: Drawing a Perfect Snowflake in Illustrator

Deke's Techniques 659: Drawing a Perfect Snowflake in Illustrator

In this week's free Deke's Techniques episode, Deke embarks on a journey close to my heart. In short, he uses his innate sense of hexagons combined with Illustrator's ability to wrangle shapes with math in order to create that elusive, precious object...the snowflake. Why is this close to my heart? I don't know. Snow? Math? Hexagons?

Full disclosure, this entire project is four movies long. But seriously, if all you're interested in is the free movie, you'll get an excellent tutorial on how to measure, duplicate, draw, transform, and duplicate again the one-sixth of a snowflake that you need to get started. Those gold-selected lines, those are the true backbone of this shape, the rest is all duplication.

If you're a member of, there is a series of exclusive movies that take you the rest of the way. First, you'll follow these mathematical machinations to flush out your snowflake (and because it's dynamically replicated, you'll only have to add the "arms" to one sixth of the design. See the gold-selected lines, that's the secret infrastructure of this shape.

In the next exclusive movie, Deke takes our delicately drawn design into Photoshop in order to add some pixel-based effects, including bevel and emboss (which wouldn't otherwise be available in Illustrator).

And finally, Deke will show you how to adjust the smart-object-based snowflake in Illustrator from inside Photoshop in order to finish the project.

Deke's Techniques 658: Automatically Converting Circles to Diamonds

Deke's Techniques 658: Automatically Converting Circles to Diamonds

In this week's free Deke's Techniques episode, Deke turns discs into diamonds in Adobe Illustrator. That is, he uses the power of Illustrator's Transform effect and some savvy selecting (and combining and ungrouping and...) in order to turn all the circles in this Windows-inspired diagram:

Into diamonds, as the shapes appear on the Mac interface:

Discs changed to diamonds in an Adobe Illustrator diagram

As Deke says, "I know that sounds like a rarefied task, not something you'd want to do on a regular basis but in fact, it is something you might want to do on a regular basis."

Arguable (and not entirely logical). But I think in this case, we'll let Deke get away with it, because even though I doubt most of us find ourselves in the service of drawing a blue cartoon paramecium, or rather, in the service of drawing a chart explaining the drawing of a blue cartoon paramecium, I can concede that there may be a time where you may need to change a bunch of shapes in some Illustrator-defined condition (a compound path, a stroked object, a group of objects) into a different shape, and this video will run you through how those various scenarios work.

In other news, the course Deke mentions, Illustrator CC One-on-One: Mastery is out and available for viewing on Learning.

Oh, and this happened over Thanksgiving break (thanks to our new friend and Thanksgiving dinner guest, Willa Kveta, and our new officiant and treasured friend and traditional turkey day hostess, Toby:

Deke's Techniques 656: Create a Concentric Ring Logo in Adobe Illustrator

Greetings from the lovely north California coast. We're traveling with all three large boy-men and a small tree this week toward our Thanksgiving destination in Mendocino county, one of the loveliest, unspoiledest places in all of the loveliness that is my home state. Here's the view from our current dining table at which I am working in peace while Deke and our three boys went out foraging for groceries:

Here's the small tree we're traveling with for reasons that may or may not become clear:

And here's this week's free Deke's Techniques subject, a fun Illustrator interwoven logo suggested by Facebook friend of Deke, Tamzid Hasan.

If you're a member of Learning, you can check out the exclusive movie this week in which Deke turns that initial pattern into a continuous octagonal creation:

Deke's Techniques 654: Op Art Experiment 3a: Volumetric waves

Deke's Techniques 654: Op Art Experiment 3a: Volumetric waves

In this week's free Deke's Techniques episode, Deke does his third set of experiments in digitally created Op Art. Inspired by a work in the Dreamstime image library, he set out in Adobe Illustrator to create this undulating pattern.

Of course, any good eye-stimulating, brain-stirring, possibly headache-inducing piece of Op Art begins with planning, especially if you're the math loving Deke. So in order to insure this experiment results in a seamlessly repeating pattern, he plots out his intentions first.

Planning a seamless patterin in Illustrator

The actual piece begins with these two simple lines...

Two simple lines destined to become a seamless wave pattern

...which are then subject to the power of Illustrator's Transform commands, and ultimately exploded into that thing that's still waving at the corner of your eye two paragraphs above.

For those of you who are members of Learning, Deke's got an exclusive movie this week in which he manipulates the initial pattern into an "optimistic" (Deke's word, no idea what he's talking about) monochrome version, aka Op Art experiment 3b: Rolling Windows.
