Deke's Techniques 334: Straighten and "Uncrop" a Photograph

In this week's free Deke's Techniques video, Deke takes a problematic but once-in-a-lifetime family vacation photo and "uncrops" in Photoshop: straightening the horizon, filling in the background, and even restoring missing detail. Here's the starting point, a wonderful moment atop the pyramid at Coba, a Mayan ruined city in the Yucután peninsula:

An epic photograph with some fixable problems

If you've ever straightened a photograph in Photoshop, you know that the rules of geometry require that you'll crop away some part of your image. So after straightening the horizon, Deke sets out to restore those areas. In the process, he also makes some room at the bottom of the image to allow for the restoration of his younger child's toes. Along the way, you can see how he uses Content-Aware fill to fill in the gaps, then fine tunes with the Healing Brush to cover his tracks. 

For members of, Deke's got an exclusive movie this week in which he actually restores the cropped off bit of Sam's right foot. (The trick is to steal it from another photograph.) Here's the finished project, suitable for commemorating this epic adventure:

A Hero In No Time: Time Lapse of Deke's Latest Retro Superhero Project

Deke's latest project turns an ordinary mild-mannered gym rat into a classic, if totally made up, Silver Age comic book superhero. Watch the extraordinary video above---created by the editing heroes at and featuring the song "Massive" by Poppy Brothers---to see this Photoshop and Illustrator-empowered metamorphosis happen in just over three exciting minutes. Yes, it's an epic saga of heroic transformation.

Turn an ordinary photo into a classic comic superhero.

If you're ready for a challenge like this, be sure to check out Deke's new course, Designs dekeConstructed: Retro Superhero, to see how each step in this Jack Kirby-inspired creation came about. You'll see how to use Illustrator blends to create the Blue Barbeque's signature human grill marks. You'll see how Deke incorporated photographic elements (the flames and smoke) in Photoshop to emulate the comic books of his youth. And you'll even see how Deke went about creating a custom font (used for the words "Fire Up," below) specially for this project.

Deke's Techniques 333: Selectively Converting Parts of Your Image to Black & White

Selectively Make Part of Your Image Black & White

In this week's free Deke's Techniques episode, Deke shows you how to convert part of your image to black & white, whilst leaving the remaining part distinctively colored. Like this: 

A selective black & white conversion leaves the cherries redder than ever

The effect is achieved reasonably quickly and efficiently thanks to the fabulous Color Range command, which allows you to make selections based on color (or, naturally, a range of color). During the course of the video, Deke claims that you can use this approach for your non-cherry-based photographs. To test this hypothesis, I applied Deke's method to something as un-cherry-like as I could find---a Brussels sprouts image by Brent Hofacker from According to the photographer, they're organic.

The verdict? I'm happy to report that the technique works for vegetables as well. One caveat, the masking wasn't quite as quick and easy as it was for Deke's cherries. The sprouts were in a brownish bowl sitting on a beige-ish background. The Brussels sprouts were less exclusively green compared to the cherries' unabashed redness. So, I ended up having to make my Color Range selection a little rougher---avoiding anything too yellow, so as not to include the background, then hand-masking the brownish-yellower bits of the sprouts with the standard Brush tool. Still, a relatively easy effect with satisfying (and nutritious) results:

Everything but the sprouts

Deke's Techniques 330: Create a Penrose Triangle of Cubes in Illustrator

Draw a Penrose Triangle in Illustrator

In this week's free Deke's Techniques episode, Deke follows up his mesmerizing möbius strip technique from last week by making yet another impossible figure, a penrose triangle:

Deke's approach is to break the figure into these orthogonal cubes, a system which, according to Deke, keeps your brain from exploding while you're trying to figure out which edge goes where. Basically, Illustrator does some of those mind-bending calculations for you. 

Check it out, and if you're a member of, there's an exclusive video this week in which Deke shows you how to add shading to the cubes to create this effect

Deke's Techniques 328: Draw a Möbius Strip in Illustrator

Draw a Möbius Strip in Illustrator

In this week's free Deke's Techniques video tutorial, Deke shows you how to make a double-looped intertwined Möbius strip in Adobe Illustrator. You don't need any special files, this starts as a hexagon, gets rounded, is blended into a double-ribbon, is next rotated and duplicated, and finally the thing gets painted with the Live Paint feature. Only the basic Illustrator skills are required, as I can attest to because I actually managed to do it myself (note the green color to prove that I didn't just copy Deke's version):

Here are some observations I made along the way: 

1. The initial outlines of the ribbon are extracted from a standard hexagon, to which the round corners feature has been applied. You can draw a hexagon, can't you. (Yes, I apparently can.) 

2. The aforementioned outlines are created by setting up copies of the segment and then using the Blend feature in Illustrator. What I discovered here is that Blend doesn't actually blend as I would define the word, but rather, it makes incremental duplicates between designated thing one and designated thing two. I'll give it to you that Blend is a much pithier name for a command though: 

3. Once a one third of the ribbon pattern is outlined, the other two thirds can be created using the Rotate command to make rotated copies at 120 degree increments. 

4. The fun (although mind-twisting) part comes when you use Live Paint to fill in the parts that are actually the ribbon and delete specific strokes to imply interweaving. 

5. For members of, Deke's got an exclusive movie this week in which he shows you how to apply these gradients and twisted edges:
