This HDR image is a three frame bracket set +2,0 and -2 EV. I merged it in NIK HDR Efex Pro 2 and finished it in Aperture 3. The flares around the lights are from the f8 aperture which adds a star burst to almost all artificial lights; the way around it is to shoot with as wide an aperture as possible which will reduce it greatly.

This HDR image was created using the same procedure as the first. I was shooting from the Big Four Bridge looking  south west from a vantage point close to the Indiana side of the Ohio River.

More Handheld HDR

Yesterday I talked about shooting HDR brackets handheld; today’s image is another example of that technique. There are many occasions or situations where a tripod is out of the question. Often those same situations present difficulties due to the extremely broad dynamic range of the subject; that is when a bracket set can assure that the entire dynamic range is covered.

In this image the light on the polished metal was extreme and a single exposure would have left the sky overexposed while the shadows would have been underexposed. By shooting a three frame bracket at +2, 0 and -2 EV I was able to capture the clouds in the sky, the details under the carburetors, the reflected light on the black drive belt in the lower right of the frame and the reflections in the windshield. By combining the three exposures in NIK HDR Efex Pro 2 I was able to bring the broad dynamic range under control.

One of the features of NIK HDR Efex Pro 2 that really helps with handheld images is the Align Images feature that can be applied at the initial merging of the brackets before any other processing takes place. I keep this feature checked for all my HDR work because even on a tripod there can be slight movement between frames; of course when shooting handheld there is bound to be some movement and this feature along with a 20% Ghost Reduction application usually solves that issue.

Finally I used the Balanced preset in NIK HDR Efex Pro 2 as my starting point to tone map the image. A little tweaking there opened up the shadows and tamed the highlights while bringing the clouds out in the sky. I then returned the image to Aperture 3 for final adjustments to exposure and some enhancement of the red and yellow color channels to saturate the brown on the car. A little adjustment to the blue channel saturation and luminance further strengthened the contrast between the clouds and sky. Lastly I sharpened the image and then took it into Photoshop CS5 and used Content Aware fill to remove a small patch of white at the edge of the photo that was there from the corner of the event sticker in the windshield.

Using Handheld Bracket Sets for HDR Images

I found another good use for HDR processing last week while photographing at the NSRA Streetrod Nationals here in Louisville. It’s always difficult to capture the details inside the cabins of these cars in a single exposure. By shooting a three frame bracket set of +2, 0 and -2 EV I was able to tame the highlights and reach into the shadows. I shoot handheld whenever I can to allow myself the luxury of being able to frame my images without the hinderance that a tripod creates. I have found that applying 20% Ghost Reduction and checking Align Images in NIK HDR Efex Pro 2 compensates nicely for any camera movement that a handheld bracket set creates. In this image you can see the texture in the carpet as clearly as if it had been shot from a tripod.

I used the Balanced Preset in NIK HDR Efex Pro 2 as my starting point for merging the three frames before tone mapping the image. I then returned the image to Aperture 3 where I completed my adjustments to exposure and contrast before applying sharpening.

For this monotone image I took the color HDR image into OnOne Perfect Photo 7.5 and used the Perfect B&W application. I started with the Ambrotype preset and then made several changes to it’s default setting. I used a cream color for the paper tone and a deep blue for the silver tones. The ambrotype preset includes a border bit I didn’t care for it so I also changed it with the border adjustment tab. I chose the Emulsion #003 and added it and I also changed the width of the edge to something I felt better fit the image. By beginning with my HDR image I was able to show the same detail in the shadow areas as I had in the color image and also control the contrast and highlights.

This is a three frame bracket set HDR image processed in NIK HDR Efex Pro 2 with 60% anti-ghosting applied. It was very breezy when I shot the bracket set but the anti-ghosting did a respectable job of merging the three exposures. As is my usual work flow I finished the image in Aperture 3.

This was a three frame bracket set -2, 0, +2 EV merged and tone mapped in NIK HDR Efex Pro 2 starting with the Deep 1 Preset. I made some minor changes to the amount and method strength. I also dropped a control point on the sky in the background where I adjusted the exposure and contrast. I then returned the image to Aperture 3 and adjusted the overall exposure, cleaned up some dust spots, and enhanced the vibrance slightly.
