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.

Photoshop Top 40, Feature #23: Color Range

Feature #23: Color Range

I have returned from Southern France. And with the exception of a few exciting airport debacles--never ever try to return your car to the "French sector" of the Geneva International Airport!--I had a great time. Avignon, Les Baux-de-Provence, Saintes-Maries-de-la-Mer. Mouth-watering cheeses, world-class wines, and chocolates like you've never tasted. Plus everyone's super polite and the speed limit is >80 mph. You can't get a decent martini, but I did manage to parlay a glass of 15-year Laphroaig, which'll tide me over in a pinch.

In the meantime, I'm in Toronto. In fact, this very day I'm teaching a full-day, super-intensive Channels & Masks seminar at the Metro Toronto Convention Centre, at which every attendee gets a copy of my book Photoshop CS4 Channels & Masks One-on-One.

So it's only fitting that today's feature is Photoshop's most successful automated masking function, Color Range. To say it's good is an understatement. Like a Châteauneuf-du-Pape wine, it is soigné. Check out the free high-quality streaming video to learn more. Read more »

Which is cause for celebration, of course. But it's also my way of saying, much may have happened since the last time you visited deke.com:

New Slickly Produced (and Somewhat Alarming) dekePod Video
For example, did you know that the mild-mannered Adobe Bridge might well be gobbling up the very last gigabytes of your hard drive and exposing your misdeeds? To learn more, check out dekePod 014: "Photoshop vs. Adobe Bridge--Beware the Cache, the Cache Must Die!"

Four MORE Full-Resolution Channels & Masks Videos Available for Download

Submitted by deke on 10 April 2009 - 12:15am.

A couple of months ago, I posted high-resolution versions of the first four videos from my book, Photoshop CS4 Channels & Masks One-on-One, absolutely free to registered members of dekeOnline. I promised there would be more, and this bright and cheerful Friday morning, I'm here to make good.

It's a shockingly valuable offer with very little upside to me other than inspiring your misplaced affection. And yet I do it. Either I have a real thing for misplaced affection. (Which I do, but that's another story.) Or I love my members. (You must be a member to receive the love.) Read more »

Welcome, welcome, every dekeOnline member.

Today, I offer you something of such real training value that I honestly question the wisdom of what I'm doing. I must be insane. Or I love you. Haven't quite figured it out.

You need to be a member of dekeOnline to proceed. Yes, it would seem both my insanity and my love are conditional. Read more »
