Martini Hour 056, In Which Colleen Is Trapped in a Mellow Yellow and Purple Groove

Hello deKats and deKittins, coming to you from a very relaxed place this week. I have no idea why. I guess it's just because it's me and my good buddy Deke, in a show where Deke does what Deke does best, go all-nerdy on some obscure issue related to graphics. This week it's trapping, that technique of building in a buffer zone in a CMYK print that's there just in case (inevitably) that the plate registration doesn't quite line up. And it's a good thing one of us is relaxed because you know how this kind of stuff gets Deke going.

But as (ahem) much as that sounds like print-nerd geekery, it actually turns out to be a very informative discussion. We cover print methods, color separation, and how you get what you pay for. We've had such exhilarating conversations with notable renegades lately, on what's ahead for Photoshop and Lightroom, and the future, and and living on the moon. I gotta tell you though, it's pretty nice to discuss old school craftsmanship with the man. Deke that is. Read more »

Russell Brown's "2010: A Photoshop Odyssey"

You may know Russell Preston Brown as that "Adobe guy" (as Steve Jobs once dismissed him) who either: 1) brought Thomas Knoll and Adobe together to create the product we now know as Photoshop or 2) wears silly wigs. He is, of course, both: serious thinker and blithering goofball. Which is to say, he's one of us: A creative thinker and a child at heart.

It's been a couple of weeks since this happened, but on February 18---at an internal Adobe/NAPP event celebrating the 20th anniversary of Photoshop, which you may remember from a recent Martini Hour---Russell proffered one of the best examples of digital-imaging performance art I've seen.

Photoshop Top 40, Feature #6: RGB, CMYK, and Lab

Feature #6: RGB, CMYK, and Lab

Color is a wild beast. One that you admire, exalt, and even brood over. But the second you think you have it figured out, it can change on you. It looks different in print, it transforms on the Web. Color cannot be caged and will not be tamed.

Even so, Photoshop tries. It knows you adore color. But it also knows the beast. Photoshop sees color for what is it, a 3D landscape of luminance levels, clawing at each other and competing for your attention.

There is RGB, the creature that is captured. And CMYK, the monster chained and offered to the world. And finally there is Lab, the beast itself. Read more »

Martini Hour 055, In Which Deke Teases Because He Loves...Photoshop

In the words of Photoshop PM John Nack, "We swear because we care." If we weren't using Photoshop everyday, reveling in its amazing almost magical powers, we wouldn't notice all those little annoying things that make our work just a teeny bit irritating. Or a lot irritating if we have to repeat certain activities often. Regular loungers know that Deke and I even have a recurring segment of Martini Hour dedicated to our "pet peeves," in which we discuss those behaviors that just seem inexplicable or unneccesarily arduous to us. Well, it looks like we may have a little less fodder for that particular segment in the future.

In this week's show, we have a delightful time with our old (younger than us) friends from Adobe, John Nack and Bryan O'Neill Hughes, who share with us the "Just Do It" list of everyday requests from users that they're working on for potential future (code: next) versions of Photoshop. The idea here is that while they're making sure Photoshop keeps up with cutting edge software possibilities, they also take some time to go back and fix smallish if long-standing irritations and work on suggestions that come from experienced users of the product. 

Here are some of the JDI improvements you may see in the not-so-distant Photohsop future:  Read more »

Photoshop Top 40, Feature #7: Undo, History, and Revert

Feature #7: Undo, History, and Revert

If you're anything like me, you sometimes make mistakes. For example, a few weeks ago, before recording the Photoshop 20th anniversary Martini Hour, I broke my foot falling down a short flight of stairs. Which was fun, because years ago, I had broken the other foot falling down a long flight of stairs. Not to mention the time I busted my teeth on a the bar of a trampoline. Or accidentally yanked a speaker down onto my head and bled so badly I had to replace the couch.

Then there was that time I cautioned a woman not to help a group of us lift a heavy object (it was a car) because she was pregnant (she wasn't). Or the time I called that other woman "Sir." Or when my buddy and I were trash-talking this guy for half an hour---I mean, really laying into what an absolute jerk he was---and then strolled out of my dorm room and found him sitting in a near fetal position by my door.
