Introduction

High Dynamic Range (or HDR) photography has been a hot topic in photography circles the last year or two. There is a very real debate about whether it’s “good” or “bad” (as with most heated debates, I believe the answer is: “it depends”). For my part, I think HDR photography can and will play a significant role in the evolution of digital photography.

The usefulness of any software technique is usually predicated on staying true to the scene and the artistic intent of your picture. If you can manage that with HDR, you’ll be in good shape! No software tool –HDR options included– can fix a poorly executed photo, but they can make a good photograph better.

The most important part of HDR photography is capturing the series of bracketed exposures, the data from which can be merged together to make a single photograph. The reason for the bracketing is so you can capture all the tonal details in the scene, from brightest to darkest and everything between.

A good rule of thumb is to vary the exposures by one stop and take additional shots on either side of a 0EV exposure. For example you might want to capture the following exposure values for your scene if it has a wide range of tones: -2EV -1EV 0EV +1EV and +2EV. A more extreme example are scenes like a downtown street at sunset or dusk, where most of the light from the sky is gone but the street lights are on, creating a mix of dark shadow details and brightly lit specular details that come from the cars and storefronts in the scene.

Capturing that entire scene would be impossible with a single exposure, even using the best cameras available. The difference between the lightest and darkest tones is simply too great. That’s where HDR Efex Pro comes in!

Introduction

The Merge to HDR Pro UI

A quick reminder: here is an example of the kind of tips you can get from Adobe Digital Imaging How-Tos…

HDR Toning is the process in Photoshop CS5 where you can create a 32-bit image from a series of exposures, and then use the new HDR Toning image adjustment to follow an HDR-like workflow. Normally if you tone map inside Merge to HDR Pro, the output must be 8 or 16-bit. This process offers a 32-bit alternative.

If you’re working in Photoshop right out of the gate, choose File > Automate > Merge to HDR Pro. If you’re working from Lightroom, select the bracketed exposures you want to use from the Grid view or Filmstrip, right-click, and choose Edit in > Merge to HDR Pro in Photoshop. If you go with the first option, this will open a dialog box for browsing and selecting your files, and for automatically aligning them. Typically I find that if I’ve photographed my scene using a tripod and trigger release, I can get a good alignment result.

Once the merge has begun, Photoshop may take a couple minutes—depending on the size of your original files, how many you are attempting to merge, and the speed of your system—to bring all the shots together into the Merge to HDR Pro interface (right). Most of the controls you see above are also included in the HDR Toning adjustment, which we will be covering shortly. They include:

  • Remove Ghosts: Uses the image (thumbnail) you choose as the basis for eliminating any blur caused by moving objects (for example, a tree branch moving in the wind).
  • Mode pop-ups: Allows you to decide if your output will be 8, 16, or 32-bit, and which tone mapping method to use. In all cases, I prefer either 16- or 32-bit Local Adaptation, as it provides the most flexibility.
  • Edge Glow: These sliders control the HDR “glow” and halo effects you may be familiar with from HDR web sites and galleries, by manipulating local contrast. These are most often the “culprit” when an HDR image looks “fake” or “illustrated”, rather than captured with a camera.
  • Tone and Detail: these sliders allow you to set the look of the overall exposure, tone down blown out highlights, open up shadows, and add detail or perceived sharpness.
  • Color: These two controls allow you to modify the global color saturation and presence.
  • Curve: Allows you to fine-tune the contrast beyond what the Tone and Detail controls can do.

The thumbnails at the bottom left of the window represent your HDR exposures. When using Remove Ghosts they can be selected individually to eliminate blur or unwanted movement. Continue reading »

It’s a problem most photographers have faced more than once: you’ve got a subject or composition you’d like to focus on during a shoot, but because weather conditions and other variables change rapidly, you must continue to capture the subject until you get it just right. Sometimes you may have dozens or even hundreds of very similar shots, if you’re shooting “rapid fire”.

However, once you’re in the Lightroom 3 Library module, viewing dozens of thumbnails that all display the same composition can make scanning your collection of compositions more difficult. Enter Stacks! Stacks can be used for multiple photographic workflows (such as gathering shots for HDR or Panoramic photographs), so it’s definitely a trick worth knowing.

For this Lightroom 3 tutorial, I demonstrate how to collapse dozens of shots into a small space, so that the overall collection of subjects is more apparent, making an evaluation of your overall shoot more simple.

Photomatix Pro 4

HDR or High Dynamic Range imaging is a relatively new workflow in digital photography, designed to compensate for our modern cameras’ inability to capture the full range of tones in a scene (in a single exposure). Another way to put that is, the camera rarely captures everything that we perceive, in terms of tonal details that span from the very brightest to the very darkest areas. Essentially HDR is a “workaround” for this limitation; we can shoot a series of bracketed exposures with our camera (using a tripod and unchanging aperture and focus point), and then “merge” those exposures together with special software tools.

There are several good HDR software programs on the market, including a built-in HDR function inside of Photoshop CS5 (learn more in my book). But the one I’d like to focus on today is Photomatix from HDRSoft. There are two versions available, Photomatix Light 2.0 (which is a simpler version, demonstrated in one of my recent articles), and Photomatix Pro 4, which is the comprehensive version reviewed in this article.

Earlier this month was the first time one of my feature articles was published in Photoshop User Magazine; it was quite an honor! This Photoshop article focuses on what many of us are facing right now: a transition in weather and environment from winter to spring, and how we can get the most from our cameras in less-than-ideal lighting and color conditions.Also included are tips for processing raw images in Lightroom and ACR, and a quick path to using Merge to HDR Pro as a way to preserve very subtle details like those found in snow scenes. Many thanks to NAPP for this great opportunity; it was an honor and I hope to work with them again this year to bring you guys more articles and tips.

NOTE: The PDF may take a few extra seconds to load so that you can view it inline. Note also that the images have been compressed for the web. Thanks for your patience!

For this year’s Thanksgiving Lightroom and Photoshop tutorial, we build on last week’s tutorial at Lightroom Secrets, where I optimized the raw images for an HDR exposure, here the images are moved from Lightroom directly into Photoshop CS5 and Merge to HDR Pro.

HDR is a popular topic these days and for my part, I see it as a way to help our cameras mimic what our eyes see, rather than a heavily stylistic type of imagery. Our cameras are not capable of capturing the dynamic range perceived by our eyes, so by taking multiple exposures and blending them together, we can get a closer approximation of what we actually see. The subtle tones and colors and the wide dynamic range. Merge to HDR Pro is probably my single favorite photography feature in either Photoshop CS5 or Lightroom 3. Enjoy and have a great holiday!

This CS5 announcements has been a long time coming, and as someone who fortunate enough to work with Adobe as an alpha and beta tester, it was a bit of a relief! :) There is so much cool stuff in CS5 that not being able to share the new capabilities with creative professionals and others like myself, was a test of willpower this cycle. Let me give you a few of the highlights from the new CS5 Production Suite.

Adobe CS5 Suites

Photoshop CS5 in particular is a really excellent upgrade. Probably the best single improvement I’ve seen in 15+ years of using the app. During that time I’ve enjoyed (along with the rest of the pixel-pushing community) the advent of History, the Brush Engine (Ps 7), and many other cool features like Vanishing Point. But CS5 takes the cake. Not only is it fully 64 bit for the Mac and PC now, but the new features are outstanding and applicable to several workflow types.

Photographers: for me the most impressive new capability is the HDR Pro function, which now provides Photoshop users with a truly professional solution for combining exposures to create high dynamic range images. There tone-mapping controls are much improved, there is a deghosting function to remove ghosts from overlaid exposures of moving subjects like trees, clouds or plants. There is also an excellent corner point feature in the Curves that allow for very precise control over image contrast region-by-region.

But that’s not all for photographers by a long-shot. We also have a more accurate an intelligent Refine Selection / Refine Edge command that uses Smart (Edge) Radius technology to quickly isolate your subject from background clutter or color bleed. And you’ve no doubt seen the retoucher’s dream by now, the Content Aware Fill command. Now there will be a lot more creating and a lot less clone, patch, heal… clone, patch, heal. :)

Still not done though. The new Luminance and Color Noise Reduction technology you’ve seen in Lightroom 3 Beta, is available in ACR 6 as well. Photoshop CS5 also has a brand new Lens Correction capability, that profiles individual cameras and lens combos and makes automatic corrections. This feature will become bread-and-butter for many photographers, as Nikon, Canon and others provide robust profiles for their pro zoom and wide angle glass. Last and certainly not least Adobe has created a new Mixer Brush and live Bristle Tips, which allow photographers to create beautiful digital paintings and photo-illlustrations from their pictures!

You can learn about all of these features and more in my upcoming  title: Photoshop 105: Retouching & Image Adjustment!

Designers: if you’re a graphic designer or work with more creative workflows in Photoshop, there are three huge additions to CS5. First the Puppet Warp tool allows you to take a subject that is isolated on a transparent layer, and warp it in realistic ways (not dissimilar to AE’s Puppet tool), while filling the hole in the background layer with Content Aware Fill. There’s also Repousse, which addresses the long-standing request for a text and shape extrusion tool in Photoshop. Be warned though: you’ll want to use a computer with a pretty powerful GPU to get the most from Repousse or other Photoshop 3D features. And the same Mixer Brush and Bristle tips noted above, can allow Photoshop artists to create painterly creations from scratch, without the need for 3rd party apps. Or at least the need will be less frequent.

After Effects and Premiere Pro CS5 also have major improvements to offer for video editors and motion graphics artists, including both being optimized for 64 bit computing, GPU acceleration and in some features, multi-core CPU acceleration. For Production Suite users, you’re going to want to have at least 12GB of RAM available on your machine to get the most from Photoshop, AE, and Pr at the same time. Remember: RAM is still relatively cheap so it’s a great way to boost performance for not a lot of money.

Video / FX: For those who are given the unenviable task of Rotoscoping, the new RotoBrush in After Effects allows you to intuitively paint around a subject and as the frames advance, using various slider settings and brush tweaks to let AE “fill in the blanks” and follow your subject around. Maybe more important in my mind is the improved performance and stability across the range of functions for Premiere Pro, and the improved speed of Dynamic Link workflows for AE – Premiere and Encore.

In the weeks ahead I will be posting free demos over various CS5 functions and linking them up here at Colortrails, so check back often!
