Thunderboomer

I shot this image last night just as a storm front was passing through Louisville. I shot seven brackets E.V. +2, +1, 0, -1, -2, -3, -4 in order to capture the full range of tonality in the scene. As I have said before I watch my histogram closely to be sure that I have no blown out highlights which for this scene required four stops underexposure.

I processed these frames in both NIK HDR Efex Pro and NIK HDR Efex Pro 2 and discovered that the later version, NIK HDR Efex Pro 2, is superior in it’s anti-ghosting capabilities as well as it’s tone mapping. I used the Realistic (Deep) preset and adjusted the tonality slider slightly while in NIK HDR Efex Pro 2. I then returned the image to Aperture 3 where I tweaked the vibrancy slider and then sharpened the image. After this morning’s experiment I am sold on the upgrade to NIK HDR Efex Pro 2 and recommend it for anyone wanting to process bracketed HDR images.

Another Louisville Sunset

Sunset on the Ohio River at Louisville, KY

Here’s another image taken at sunset from the Clark memorial Bridge. I can’t stop going downtown and shooting from the bridge. This particular evening the sun was just dropping below the horizon and the colors were amazing. I especially like the way the sunset is reflected in the Yum Center windows.

The composition relies on the balance of the building and roadway with the texture of the clouds. There is also a complimentary color harmony going on with the blues of the sky and the oranges in the sunset.

I processed this image using NIK HDR Efex Pro using the “Realistic Strong” preset and Aperture 3 for final sharpening.

Golden Hour on the Clark Memorial Bridge

This image is on the Clark Memorial Bridge approach from Louisville looking north into Indiana. I chose this composition because I like the way the bridge railing and sidewalk lead the viewer’s eye into the image. The afternoon glow of the “Golden Hour” on the bridge and in the sky is a nice contrast to the coolness of the shadows in the lower third of the image.

I processed this image in NIK HDR Efex pro using the Realistic (Strong) preset as my base point. After the six images were merged I applied the anti-ghosting at the high setting which cleaned up the cars on the bridge and reduced the ghosting they were exhibiting. I then slightly adjusted the shadows and highlights sliders before saving the image back into Aperture 3. I then reopened the photo in Aperture 3 where I did some further enhancement to the colors and vibrancy before the final sharpening.

Louisville Waterfront Sunset

Louisville Waterfront Sunset

I took this image last week from the Clark Memorial Bridge. I used five exposure values +2, +1, 0, -1, -2 to capture the scene. I then processed them in NIK HDR Efex Pro to merge and tonemap the image. I also reprocessed the merged image with the anti-ghosting feature set at medium to clean up the vehicles on the highway and any ghosting in the clouds.  I chose the Realistic Strong preset as my starting point and then tweaked the sliders until I had the colors and details where I wanted them. After that I returned the image to Aperture 3 for a little boost to the color temperature and sharpening.

I am especially pleased with the way the sky is reflected in the YUM Center in this image. I had been trying for several weeks to catch a sunset that was dramatic enough and high enough in the sky to reflect in the building’s convex glass. I checked cloud maps every evening for almost a month in hopes of being able to capture a dramatic sky such as this one. Many times the clouds would be where I wanted them 30 minutes before sunset only to fade away just as the sun set. On this particular evening the cloud map showed a  lot of clouds out to the west so I set up my camera and tripod on the Clark Memorial Bridge and waited for their arrival. I was rewarded by these clouds moving in at just the moment  the sun was setting.

Studying your location and accessing relevant sources, such as the cloud map, can really help when seeking to capture an image that you see in your mind’s eye. Keep this in mind the next time you wonder why you can’t seem to catch the scene you are seeking, patience and planning will eventually pay off if you do your part too.

Louisville Waterfront at Night

Posted on by Nick Roberts

One of the difficulties inherent in shooting night scenes is the large dynamic range needed to capture the scene. The artificial light in the image is usually much brighter than the surrounding areas. When this occurs the highlights are blown out which is almost always in the street lights. This image is one such situation. I shot this image using a five shot bracket series from +2 through -2 stops. Even at that range the centers of the lights are blown out in this image.

My studies of my images at night have led me to adopt a wider range of exposures to offset this undesired effect. My current practice is to go as many as five stops underexposed if I encounter scenes that have large ares of manmade lighting such as this one. I watch my histogram very closely and underexpose until I see the right hand side move completely away from the end of the histogram. I have discovered that by doing that I can subdue the blow outs that occur in the lights themselves.

I merged the five exposures in NIK HDR Efex Pro and then used the default setting as my base to tone map it. I then tweaked the sliders until it was where I liked it and finally returned it to Photoshop CS5 to sharpen it using the unsharp mask tool.

Compositionally I framed the shot with the sunset in the right hand third of the frame in order to balance it with the waterfront on the left. The sky counterbalances the architecture and the complimentary colors of the deep blue sky and the orange waterfront create a harmonious whole.

My point in sharing this image is to show you that the conventional practice of using an automatic bracket set to shoot the scene is not always going to give you control of the entire dynamic range. By using the histogram as a tool to analyze the images in your HDR shoots you can take control and prevent blown highlights such as the street lights in this image.
