Deke's Techniques 034: Coloring the Stripes on a Zebra

Last week, I changed a red car to solid gold and then, in the lynda.com Online Training Library, to jet black. This week, I do something very nearly resembling the opposite. That is to say, I take the "black" (cuz they're really dark gray) stripes on a zebra and render them in color. Which you might not regularly find yourself doing to a zebra. But you may want to do, say, a piece of black-and-white artwork.

Here's the official description from lynda.com: Read more »

Uses for the (New??) Subtract and Divide Blend Modes

Submitted by deke on 12 July 2010 - 12:15am.

There's been a fair amount of interest around the Subtract and Divide blend modes that Adobe recently added to the Photoshop CS5 Layers panel. Subtract is not actually new; it's been around forever in the Calculations and Apply Image dialog boxes. And even in the Layers panel, where Subtract is a freshman, you could achieve the same effect by inverting a Linear Burn layer. The Divide mode, meanwhile, is slightly-more authentically new. (Inverting a Color Dodge layer produces an identical effect, but previously there was no mode named Divide.) Even so, they have their uses. Which is why Blend Mode Man so enthusiastically contemplates their formulas below:

It's okay if you're afraid. You'd have to be as wicked-cool as Blend Mode Man to smile in the face of such bewildering information. Thankfully, it only gets easier from here. (But you'll have to be member to read more.) Read more »

Feature #11: Opacity and Blend Modes

Welcome to a block of the most powerful options inside Photoshop: Opacity and Blend Modes. These include the options at the top of the Layers palette, not to mention those associated with the brush tool, the Calculations command, and a whole lot more. What these options do is blend pixels together, entirely parametrically--meaning no harm done--using math. Beautiful, lovely, gorgeous math. Read more »

dekePod Episode 018: Okay, I got good news and I got bad news. Good news first: dekePod has caught up with its younger sibling Martini Hour. For this brief moment in time, both are 18.

Also good, this new episode, it's a doozy. In this video, I show you how to turn any portrait shot--even a sweetly syrupy photo of two youngsters in real honest-to-gosh puppy love--into a credible Andy Warhol silkscreen effect. Complete with minimalist outlines, vivid fills, and lipstick that covers the teeth. Here's the official marketing description: Read more »

The Scent of Stamina

Submitted by deke on 8 December 2008 - 4:27am.

First, my abject apologies for being so absent as of late. I, Colleen, David, Tim -- as well as names you don't know, like Toby, Carol, Ron, Julie, and the splendidly monikered Spink (I monikered her, which is why it's so splendid) -- have been so thoroughly buried by this Channels & Masks book (see below) that there is literally no time for anyone on the team to scratch his or her respective butt. We keep asking each other, "When you get a spare sec, will you please scratch my butt?" But the response is always, "Are you kidding? If I had that kind of time, I'd scratch my own butt. It's so itchy!"

Seriously, for the first time in I don't know how long, I went for 4 entire days without a shower. My beard had grown so far up my face, it was threatening to become one with my eyebrows.

But as disgusting as I was (I'm slightly cleaner now), the book is beautiful. A work of tortured but honest art. Here's a tiny view of a sample page spread. This is the actual InDesign view, with my editors comments (those from Carol and Spink) out in the margins. To see it in legible dimensions, just click on it.
