Big Four Bridge
Click on the image to open it at a larger size in another window.
Yesterday morning I was given the opportunity to ride in the man lift to the top of the Big Four Bridge. Even though I am very scared of heights I jumped at the chance. It wasn’t nearly as frightening as I thought it would be. The guys on the job gave me a safety harness to wear that would keep me from falling off the bridge and away we went. Tim, the guy operating the lift, was very comfortable and his calmness made the trip easy. At first I was content to just be even with the top of the bridge but after a few shots there I asked Tim to lift me higher so I could shoot down on the bridge. We spent 10 minutes or so while I looked for my compositions and shot a few quick studies of the scene from there.
I’m heading back there this morning and I may even get the courage to walk out on the bridge itself. As I write this I wonder if I’ll be able to step out of the basket on the lift or if I’ll have to content myself with shooting from the safety of the lift.
Isaac Was Coming to Visit

Today’s image is another shot from Waterfront Park looking east. As I mentioned in my earlier posts this week I expected some dramatic skies with the approach of Hurricane Isaac into the Ohio River Valley. I wasn’t disappointed and my early arrival in Waterfront Park revealed this scene as it unfolded before me. It was around 7:00 AM and the sun had not quite risen over the horizon, the clouds were layered across the sky and the sunlight was just starting to filter up through them. The colors and texture of the sky were exactly what I had hoped for as drove into the city to shoot from the eastern end of Waterfront Park. The building on the left is the University of Louisville Boathouse and the building in the center is a new condo complex being built adjacent to the new Louisville Marina.
I decided to process this image from a single file, from my bracket set, to see how well NIK HDR Efex Pro 2 would handle it. The more I use NIK HDR Efex Pro 2 the more impressed I am with it’s ability to render the image in a way that suits my vision for it. More and more I am able to use NIK HDR Efex Pro 2 on single frames and achieve realistic HDR images that rival those, that in the past, required a large bracket set to produce. I’m not interested in seeing how many images I can merge just for the sake of saying that I did it. As I see HDR processing it is simply an extension of the Dodging and Burning that I was doing years ago in the darkroom when I wanted to tone down the highlights or open up the shadows.
My goal as a photographic artist is to produce an image that captures my personal feeling and vision for the scene and if I can do that with one or two images I’m quite satisfied. This does not mean that I am giving up on using multiple images over a broad exposure range when I need them in order to capture the entire tonal range of a scene that is beyond the capability of my camera’s sensor. It simply means that I have more options at my disposal. NIK HDR Efex Pro 2 is a super program and I recommend that you try it for yourself.
After processing the image in NIK HDR Efex Pro 2 I returned it to Aperture 3 where I adjusted the vibrance slider, retouched a few sensor spots, cropped out a billboard on the right side of the frame and finally added some sharpening before saving it as a jpeg for the web.
Sunrise in Waterfront Park

As Hurricane Isaac moved north on Saturday I headed for Waterfront Park to capture what I hoped would be a dramatic sunrise. Isaac came past Louisville Saturday from the southwest. As a result most of the clouds were still off to the west of Louisville and the edge of the storm was just coming into Louisville early Saturday. This gave me an opportunity to photograph a rather dramatic sky before the body of the storm settled in north of Kentucky across central Indiana.
Instead of using my entire bracket set for this image I decided to try using the +2, 0, and -3 Exposure Values, three exposures instead of the six I shot, to see if I could produce a realistic HDR image. I found that doing this really lightened the load on my iMac processor and markedly speeded up the merging process in NIK HDR Efex Pro 2. My iMac is at a disadvantage when using the latest software because the GPU is too weak for some software to use so all processing must be done by the CPU. It doesn’t affect the final images but it does slow down my processing time considerably if I must use all images in a bracket set.
I noticed some Chromatic Aberration in the trees so I employed the Chromatic Aberration feature in NIK HDR Efex Pro 2 and removed a purple fringing that was occurring in the image. I used the Deep 2 preset in NIK HDR Efex Pro 2 to tone map and adjust the tonality before returning the image to Aperture 3 for final processing. The rental Nikon D90 I’m using has a lot of spots on the sensor but since it isn’t mine I’m not taking any chances of damaging it by attempting to clean it. Instead I must go over each image with a fine tooth comb looking for sensor spots. Aperture 3 does good job of removing these spots when I use the Retouch tool Spot and Patch feature. It is tedious work and I’ll be happy when my camera is back from repair, fresh and clean, and in proper working order. I also adjusted the Vibrancy and Sharpened the image before exporting it for the web.
A Postcard From Louisville
Click on the image to open it at a larger size in another window.
I took this photo this morning from the Big Four Bridge looking southwest into Louisville. After cropping and adjusting the image in Aperture 3 I took it into NIK HDR Efex Pro 2 where I applied one of the Realistic presets, Deep 2. I adjusted the tonality as well as the black and white points before applying the Graduated Neutral Density filters. I dropped the sky approximately 1 stop and opened up the lower part of the image approximately 1/3 stop before adding the vignette to the final image.
