Use Camera Raw as a filter to selectively desaturate a color photo.
Deke shows you how to use Photoshop CC's ability to apply Camera Raw as an editable filter to change the colors in a photograph.

Photoshop Top 40, Feature #14: Gaussian Blur

Feature #14: Gaussian Blur

Hello, friends. I just today set down in the relatively warm embrace of Southern California. (Relative by comparison to Colorado, which has been anywhere from brisk to cheek-freezing cold.) Which means that after a lovely string of trips to such faraway places as Avignon, Amsterdam, and Big Sky, Montana, I have arrived--rested and restored--with the intent to record more videos for my beloved online training provider, lynda.com. Although the nature of those videos is Top Secret, I can assure you: They will be authoritative, comprehensive, and multitudinous.

While you await those flicks (they won't be available for months), I have this one for you. It falls under the heading Photoshop Top 40 and goes by the name Gaussian Blur. Someone new to Photoshop might be tempted to dismiss Gaussian Blur as something that makes stuff blurry. But the stalwart GBlur goes to the heart of what makes Photoshop Photoshop. The term Gaussian might be best described as the thing that makes another thing drift eventually and incrementally into oblivion. Gaussian Blur underlies the Feather command, the Drop Shadow layer effect, and even Unsharp Mask. Simply put, it is the heart of detail-, depth-, and focus-enhancement in Photoshop. Read more »

The Big and Gritty Black-and-White Sky

I celebrated the New Year with a winter sports vacation through Jackson Hole, Wyoming and Big Sky, Montana. Folks call it Big Sky Country, but between you and me, the tall mountains leave a narrower-than-average glimpse of the sky. (Pancake-flat Nebraska, now that's some big sky.) But the land is huge. Vast and sparse. Peopled but underpopulated. Earth on an almost antique and undeniably humbling scale. And the sky aside, ultimately enormous.

In this post, I present you with 13 black-and-white images, all but one captured with an Olympus E-30 or Stylus 1030. Some might call it a travelogue, but I see it more as an experimental portrait of space. I say “experimental” because many of these images exhibit flaws. Beautiful and purposeful flaws. My idea is that a digital image, like a painting, tells a story beyond that of its subject matter. A story of process and approach, one of development and media, a documentation of the power and limitations of tools.

Consider the Grand Tetons below. Comprising 11 vertically oriented telephoto photographs, this 500MB composition is a testament to the power of Photoshop’s Photomerge command. But the moment I attacked the image with the Color Range command--with the sole intention of enhancing that big sky--I revealed a series of striations across the clouds and foreground snow. (Click the thumbnail below to reveal the image in detail.) Normally, I would retry the effect to avoid these artifacts, but this time, I added Levels, Black & White, and Smart Sharpen with an eye toward exaggerating the effect. I did everything with layers--nondestructively, as it were--and yet plainly the image is stressed.

That said, I for one like the results. Read more »

Martini Hour 047, In Which Deke Displays His International Interviewing Skills

What does it take for Deke and I to float outside our Design Premium Suite comfort zone? Well, transport us to another country, give us a new product, and hook us up with a couple of gracious Adobe evangelists. Last month, while still at the Netherlands User Group meeting in Amsterdam (Adobe User Group XL, aka #augxl) we caught up with the two keynote speakers from the conference, Serge Jespers and Jason Levine, both of whom have multi-syllabic titles at Adobe that they reveal during the show. Fortified with Jenever, Deke and I forayed into uncharted waters with our two stalwart and generous guides (who also graciously put up with the scent of raw herring wafting through dekeLounge Amsterdam).

Our first port of call was Adobe's upcoming new application, Flash Catalyst. What, exactly, is Catalyst you ask? (Have I been reading Jr. High School newsletters you ask?) Well it's a program that lets you, our beloved creative types, control the design of your web pages and AIR widgets, and then hand off your hard work in pixels in the form of live code for your favorite developer. And you can currently download said product in beta form from Adobe Labs. Pretty cool.

But wait, there's more.

Photoshop Top 40, Feature #15: Alpha Channels

Feature #15: Alpha Channels

UPDATE: The good folks at lynda.com have replaced the bad old corrupted version of this video with a new one that plays properly. Thanks to everyone who let me know that the old one was messed up!

Masking an image is like poking a hole in the background to reveal the foreground. I use this analogy because A) I'm growing a bit weary of the "white reveals, black conceals" line; B) I'm just coming off a ski vacation in Big Sky, Montana, at the end of which I wiped out on a bunch of rocks at the top of the 11,166-foot Lone Peak (see diagram) and poked a purple-looking hole in my knee; and C) masking is exactly like that, except not so purple.

Martini Hour 046, In Which Colleen Discovers Her Dutch Counterpart

And when I say "going native" below, I mean slurping up some Jenever accompanied by raw herring. The latter was brought into the dekeLounge Amsterdam by Deke's Dutch publisher, Bob Van Duuren and his partner, Wouter Vermeulen. (You'll probably still be able to smell the fish and its itinerant pickles and onions in next week's show.) We sit down with the braintrust of Van Duuren Media to find out about translating Deke's books, publishing computer books in the Netherlands, and the love of "vintage" software.

The revelation of this week's show is that Bob is Deke's idol. You see, after years of writing books (and translating a few of you-know-whose into Dutch), Bob went off with Wouter to start his own publishing company. Van Duuren Media now threatens to be the top computer book publisher in the Netherlands. Part of their success is apparently based on Bob's undying love for Corel's Ventura Publisher. Listen as Bob and Deke stroll down the memory lane of graphics software, while Wouter and I just worry if the books will be published on time. They're like our Dutch mirror-images.
