Using Iris Blur in Photoshop CS6 to direct attention

One of the niftiest new filters in Photoshop’s bag of tricks is the Iris Blur filter. It mimics the behavior of limited depth of field by blurring the image outside a customizable “iris” shape. As usual, Photoshop provides plenty of options for controlling the radius of the non-blurred area (both an inner “hot spot” and outer "total effect” area), the shape of the iris, and the amount of focusing you want within the iris. Unlike using a wide-open aperture on your camera to blur the background, Photoshop doesn’t “know” which objects are close or far, so you need to craft the shape of the iris yourself. Fortunately Photoshop also lets you add multiple different iris blurs to create effects that would not be possible with a camera…

From birds to blooms in the Texas Hill Country

Our Texas Hill Country photo workshop drew to a close today with a full day of photography. We started this morning in the excellent blinds at , with our co-hosts Larry and Sharron Jay making sure we not only had a great breakfast, but were well set up for the arrival of the sun and songbirds.

Fixing lens flare using Photoshop CS6’s Content-aware Patch tool

Lens flare can be a major problem when photographing wide-angle scenics, especially through large groves of trees. Sometimes the sun is close enough to the frame that it isn’t possible to completely block it out without changing the composition of the photograph. Removing it after the fact is difficult if not impossible with traditional photo editing tools. One common approach is to use the Patch tool in Photoshop. Fortunately for all of us, the new Photoshop CS6 Patch tool can be made content-aware, and does a remarkably solid job helping fix lens flare…

Some raptors are friendlier than others–”rehab” Harris Hawk

We took a break from songbird photography this morning during our workshop at for a great session with John Carter and some of the raptors he works with at . These are birds that are either imprinted on humans or for some other reason can never be released. He brings them to schools for educational programs – and out to let us photograph them from time to time. This Harris Hawk was getting some “flying time” while she was out, and decided that my camera made a great perch for her. Fortunately neither claws nor sharp beak took advantage of the camera, and the bird was polite enough not to soil it. It made for a fun moment, though!

Learning to use Nikon Flashes: Book Review of Nikon’s CLS

Each generation of Nikon flash systems has become more powerful and flexible, but also more complex. Understanding how the latest version, dubbed Creative Lighting System (CLS) works, and how to make the most of it, can be a daunting task, especially since each Nikon flash unit has slightly different controls, and works in a slightly different way. Fortunately, Mike Hagen’s new book, The Nikon Creative Lighting System, provides an easy-to-read, soup-to-nuts, dissection of CLS and specific, detailed instructions on how to use it with just about every model of Nikon flash – both on and off camera.

Finishing a photo with Photoshop CS6’s Adaptive Wide Angle filter

While not one of the marquee new features of Photoshop CS6, the Adaptive Wide Angle filter can help with one of the trickiest post-processing situations – correcting the distortion caused by using a wide angle lens. At the same time it can help reshape the image to draw attention to the subject in an image, which can be tricky if the subject isn’t the closest object to the camera….
