Traditionally, an HDR image is created by merging 3 or more photos together that were taken at different exposures. By doing this, you maximize the details in all elements of the photo; underexposure to grab sky/highlight detail, correct exposure for midtone detail, and overexposure for increased shadow detail.  However, taking three identical shots is not always possible, especially when your subject is moving. With Photoshop Camera Raw and a few other tricks, it is possible to imitate the HDR effect with a single photograph.

For this tutorial, we’ll take this photo I took of a dive shack in the Belizean Cayes last year (below).

Begin with a RAW image whenever possible. Open the image in Adobe Photoshop Camera Raw. This is the best place to make major changes to an image without losing pixel integrity. To artificially create the effects of a HDR photomerge, we are going to drastically alter some of the RAW settings. Begin by underexposing the image with the “Exposure” setting (in the “Basic” tab). Next, slide the “Recovery” button all the way to the right, or close to it. This will help retain detail in the sky/highlights. Then slide the “Fill Light” setting to the far right as well to fill in shadow detail. The “Blacks” slider can be adjusted to darken the shadows and give more contrast and depth to your image. The “Contrast” slider should be used to adjust the contrast and give your image a dramatic look. The “Clarity” slider should also be moved dramatically to the right – this helps to give exaggerated edges to your details.

Many HDR images also feature selective over-saturation. I use the “Saturation” and “Vibrance” sliders sparingly, and prefer to use the HSL/Grayscale tab in Camera Raw instead. Screen shots below explain the settings.

Next, open the image in Photoshop. We will now apply some filters to achieve even greater effects.

Start by going to Image>Adjust>Shadows/Highlights. Use this panel to lighten some of your shadow features, and enhance your highlight detail. This will also create a “glow” effect around contrasted elements of the photo, like the shack and the sky in our example.  

Next, create a duplicate layer of your image in the “Layers” window. Select the top layer, and go to Filters>Other…>High Pass. Be careful not to overdo it on this filter, or your image will look grainy and too sharp. A radius of just a few pixels should do it, depending on your image size and quality. This will render the top layer into a sort of grey textured image. But we will use this layer to create a combined overlay effect with the background layer.

In the Layers window, go to the drop-down menu at the top of the window (default value is “Normal”). You will see a list of options for blending layers. Depending on the severity of effect you desire, select “Overlay”, “Vivid Light”, or “Linear Light”. You can play with these settings to see which one achieves the look you are after. Once you have applied this effect, flatten your image.

Next we are going to sharpen our image with Filters>Sharpen>Smart Sharpen. Again, a little bit goes a long way, so don’t get too crazy with this setting. But using it wisely will help to give that HDR-sharp look.

Once we do this, we will turn right around and use the Smart Blur filter by going to Filters>Blur>Smart Blur. This will help to soften the image just a bit, without losing detail. It will also help to eliminate any noise you created by sharpening and High Pass filtering.

Now let’s take a look at the final result! Without using 3 different images, we achieved similar results to an HDR photomerge. Ta-da!

Climbing is one of those sports which, in theory, is entirely egalitarian. Different body types lend themselves to different climbing styles, and women can just as easily send a 5.13 as men. Granted, perhaps the style of 5.13 may be different, but it is a fact that some of the best climbers in the world are women. Lynn Hill, Katie Brown, Steph Davis… just to name a few.

As a climbing photographer, and a female climber, it has been my personal mission as of late to take more photos of women climbing hard. Despite the 10:1 male to female ratio in the climbing community, I’ve been able to shoot some photos of some very inspiring ladies. Below are a few from my recent trip to Indian Creek, Utah.

Rachel Greenburg on "Scarface" (5.11-)

Megan Polk on "Family Home Night" (5.12)

Megan Polk on Pitch 2 of "Heat Searcher" (5.11+)

It was a pleasure both to shoot photos of these ladies, and to get to know them. Since my personal resolve for climbing has faltered in the past 2 years, it’s refreshing to meet other women who have overcome hardships while climbing, and have returned to the sport. For the first time in a long time, climbing has not only inspired me artistically, but physically and mentally as well. I look forward to returning to Utah next week.
