HDR + ACR in Photoshop CC

My guess is that many of you already appreciate the wonders of HDR. But just in case, here's the idea: Armed with a digital camera, you capture multiple exposures of a single scene. (Most commonly, you set your DSLR to rapid-capture three or more "bracketed" shots, which can be accomplished handheld or with the aid of a tripod. Check your manual.) Then you use some form of software to merge the exposures into an astonishing work of highly detailed imagery.

If you live and breathe HDR, the best tool is a program called Photomatix Pro from HDRsoft. It costs $99. Which is only fitting this time of year. You deserve a gift, am I right? Yes, I'm right.

Meanwhile, for you Adobe enthusiasts, there's Photoshop CC. It offers the ability to merge multiple exposures into a whopping 32-bit-per-channel composite and then develop the result in ACR, better known as Camera Raw. Photoshop CC costs considerably more than Photomatix. But, of course, Photoshop has other jobs to do.

Here's an example of HDR in Photoshop CC:

Skyline Arch in Photoshop HDR

That first image is the initial HDR merge of five exposures that I caught of Skyline Arch (high atop Arches National Park, Utah). The second is my development of the 32-bit-per-channel image in Camera Raw. In the third image, we start tripping with Motion Blur set to the Luminosity mode. And fourth, the best use for Radial Blur I've come up with in years, set to 70% opacity.

The overhead is huge. A typical 32-bit 22-megapixel ACR-HDR composite weighs in at close to 1GB. (Seriously wtf?!) But what you can do, you would not believe.

I reveal all in next week's Deke's Techniques. Read more »

Introducing Introducing Photoshop: Design (No Experience Required)

The repetition in the title above is not an indication that I've started the martini hour early today. Actually, it's an indication that the current state of the dekeBlog doesn't allow for the use of italics in the header. Thus, I can't cleverly and clearly, entitle today's post "Introducing Introducing Photoshop: Design." And yet, that is what I'm prepared to do.

Over at lynda.com, today marks the release of Deke's new course Introducing Photoshop: Design (which will be followed in the next several weeks by more dekeHandshakes to various denizens of the Adobe Creative Cloud). This particular course is designed to take you from square one---as in, never having used Photoshop before---to practical knowledge of Photoshop's everyday tools for designers. (Gosh, italics sure are useful.)

Introducing Photoshop: Design, No Experience Required

Sure, for many sophisticated dekeOpolitans, this course will be too basic. But we know darn well that there are people out there, we like to call them dekeOlytes of the Future, who are a) full of creative design ideas b) lured to Photoshop, but then c) abruptly scared away by its sheer complexity and the time it must take to acquire a functional knowledge of the program. 

This course is for those who want to get something done, get their hands nice and dirty with pixels, but don't have time for an encyclopedic approach like Deke's One-on-One series. It explains basic Photoshop concepts that beginners with a design project need, like understanding layers and selections or how to use the brush and pen. 

(Of course, if you do want the comprehensive approach, Deke's Photoshop CC One-on-One: Fundamentals is the place to start.) 

So if you are (or if you are acquainted with) someone who could use this kind of quick up-to-speediness, point yourself (or your aforementioned acquaintance) toward Introducing Photoshop: Design. And if you need a free week at lynda.com to check it out, you can sign up for a trial subscription at lynda.com/dekeRead more »

Feedback Loop: Perspective Grid in Illustrator?

This week's Feedback Loop episode is brought to you by the dekeOmmunitarian known as "Sponge.Tool," who wonders why Deke chose to omit coverage of the Perspective Grid in his latest Illustrator CC One-on-One: Mastery update. Here's the conversation:

Good stuff, but....

Why no more love for Perspective Drawing?, I noticed it didn't show up as a chapter in the CS6 Mastery course either.

Anyway, as always, glad to see this out, buttons pressed -'Queued' for viewing.


Yeah, I mulled over that one
Submitted by deke on 30 October 2013 - 7:20am.

What with the ongoing nature of the Creative Cloud, we're trying to create courses that I can update every so often on a moment's notice, whether in the event of impending necessity or just because we have nothing better to do.

The Perspective Drawing feature was one of those things that didn't seem to gain a lot of traction last time around. So I left it out this go around. But if anyone feels like, "Good Gawd, you fool, you've made a terrible blunder!" please tell me, and I'll either pretend I didn't hear you or get to work pronto.

Given the incessant nature of CC, I have a feeling you'll be telling me, "Good Gawd, you fool, you've made a terrible blunder" an awful lot in the upcoming months. Which is okay, b/c given my haughty nature, I need to be reminded of that. 

OK, some observations: 1) Deke, I would not want to mess with this community member should you ever decide to omit coverage of the Sponge tool, and 2) are we sure this is really Deke, because it's time-stamped at 7:20 a.m.

More to the point, 3) You can still see Deke's take on the Perspective Grid in Deke's Illustrator CS5 One-on-One: Mastery course. I tested it out, and as near as I can tell the only thing you'll have to extrapolate is that the Illustrator interface is now a tasteful dark grey by default. There are even a few free movies for those of you who aren't members of lynda.com. (You can click any blue link in the Table of Contents for any course at lynda.com and see unlocked movies.) If you're too lazy to even do that, here's one:  

Of course, if that inspires you to study Illustrator (CC, CS6, CS5, CS4...) Read more »

Feedback Loop: Odd Sound in One of Deke's lynda.com Videos?

Recently, dekeCommunity member TechyJC pointed out that there was a shift in the audio quality in one of Deke's courses. I thought it sounded otherworldly, but Deke agreed with John that it just plain sucked. (Actually, as you can see in the conversation, John is more polite than that.)

I want to take a moment to thank John for the heads up and to point out how valuable this kind of information is---especially because, even if we wanted to, there's no way we could review every bit of dekeVideo that comes out. (And really, we get enough Deke as it is.) 

The folks at lynda.com conscientiously put each video through a quality control test before it sees the light of day, but as with any system that has lots of moving parts (and moving people), odd hard-to-spot production issues can sneak through the process. Thanks to John, the lyndaFolk are working on tracking down the source of the off-sounding sound.  Read more »

Frightday Fundamentals: Mastering Elliptical Alchemy for Savvy Shapes and Selections

Wait, Halloween is over, you say? Friday is over, too? Well, I don't care. Despite having originally crafted this review of how the ellipse tools work in Photoshop before Halloween (and thus before Friday), while I was hauling across Wyoming in the middle of the night and diving in a crater in Utah to get my scuba certification, I was also simultaneously coming up with a reason that the post-Halloween era is even more frightening. Because that's just the kind of renaissance woman that I am. 

So, I bring you my slightly spooky review of how the ellipse tools (the Ellipse tool proper that makes a shape or the Elliptical Marquee that makes a selection) work when you hold down various keys while you're dragging with it. I bring you: 

What follows are some, uh, Thanksgiving-themed illustrations that demonstrate how to use the Elliptical Marquee to select much more than a circle, without ever using anything but an ellipse. 

For example, with the elliptical marquee in hand, you can drag out an ellipse of any proportion. Hold down the Shift key to create a perfect circle. Hold down the Alt key to make the point where you start dragging the center of your shape. Note that for this simple selection, the cursor is just a standard crosshair. 

Once you have one selection, you can add another to it by holding down the Shift key when you draw your next shape. You'll know you're adding to your original selection because the cursor has a plus sign on board.  Read more »
