Morning On The Ohio River #2

I have been trying to catch the sunrise each morning from the Big Four Bridge. Yesterday I arrived at the bridge at the same time that a cold front was moving in from the southwest. The weather forecast was for rain to start by 10:00 am and the sky was very active as the front progressed.  I decided that it might be interesting to shoot the river and the Kennedy Bridge as I watched the clouds build up.

I set up my tripod looking west from the ramp going up to the Big Four Bridge and captured several five exposure bracket sets of the Kennedy Bridge. Back in the studio I opened the morning’s shoot and found this image. I usually try to get several variations of my subject when I shoot as I have learned over time that the best way for me to evaluate a composition is in the studio on the monitor. I chose this image because I liked the way the handrail swept into the frame.

I used all five exposures +2, +1, 0, -1, and -2, which I merged in NIK HDR Efex Pro 2. I used the default preset in NIK HDR Efex Pro 2 as my starting point as I started my tone mapping. I liked the way the sky and bridge had turned out but the lawn had acquired an over saturated green tone that was in conflict with the blues and grays of the rest of the image. I dropped a control point into the grass and desaturated it slightly to get it back to what I saw as I shot the scene. I find that these control point adjustments work well when there is a marked difference in the colors in the image where they are applied. In this case the green was so distinct in the image that it worked like a charm.

I returned the merged TIFF image to Aperture 3 where I adjusted the vibrance very slightly and applied some sharpening before exporting it as a jpeg for the web.

Back to the Distillery Again

I got up this morning and all I could think about was going back to the abandoned distillery I found last week. I had some ideas I wanted to try out using my 12-24 mm lens to shoot a panorama of this structure. I think I’m beginning to become obsessed with this place and the other unique buildings on the property but that may be coming to an end. Today I was discovered by one of the caretakers of the property who asked me to leave. Since I was trespassing I didn’t argue with him and to be fair he was very polite about the situation. He explained that a couple of weeks ago some vandals had set a fire in the road outside the property and the owners had instructed him to call the police and have anyone found there arrested. He said he wouldn’t do that today but he did let me know that I had been warned about trespassing and that he might not be so understanding if he found me in there again.

I shot this panorama as a four shot bracket set at five different camera angles horizontally. The 12-24 mm lens has a little too much distortion for this technique so if I ever get back in there again I think I’ll shoot it at 50 mm. I merged the five frames in Photoshop CS5 and then cropped the final image before taking it into NIK HDR Efex Pro 2 for tone mapping. I then took it back into Aperture 3 when I slightly reduced the saturation and boosted the vibrancy and structure before sharpening the final image.

I also rendered a copy in Black and White using an orange filter in aperture 3. Please take the time to comment and let me know which version you like best and why.

Exploring an Abandoned Distillery (Part 4)

I thought I would end the week with a couple more shots of the distillery I was exploring. This first image was processed in NIK HDR Efex Pro 2 using the Realistic 2 setting from a five shot bracket set. After merging the five shots and adjusting the Tone-Mapping and Tonality sliders I returned the image to Aperture 3 for some minor straightening and cropping as well as sharpening it for output.

I cropped into the image slightly to make the column on the right a stronger foreground element and to direct the eye into the frame. The repitition of the columns unifies the scene and also creates movement within the frame.

I decided to do a Black and White version as well which is the image below. I used NIK Silver Efex Pro to convert the photo to B&W and applied an orange filter to punch up the contrast slightly. I chose the Kodak Panatomic X ISO 32 film setting to get the dramatic blacks that I used to get from the same film in the darkroom.

Resting Spirits

Resting Spirits

Yesterday morning I joined 25 or 30 fellow Louisville Photographic Society members for a tour and photo walk at the oldest continuously operating distillery in the United States, Buffalo Trace Distillery, located in Frankfort, Kentucky. The tour included a great deal of the lore and history of bourbon making and it’s deep roots in the central Kentucky region. We were very fortunate to have as our guide a third generation employee of the distillery Freddie who gave us a behind the scenes look at the distillery and the history of whiskey in Kentucky. Freddie took us into the warehouses and explained the way that the whisky ages in the barrels and why they are placed where they are in the warehouse. The barrels placed at the lowest levels are there for a long slow aging process that imparts the characteristic flavors of the charred oak barrel and the tannins in the oak to the bourbon inside.

I shot this image as a bracketed set of exposures for HDR processing. I first processed it as a color HDR image in NIK HDR Efex Pro 2 where I tone mapped it using the realistic preset before returning it to Aperture 3 for final adjustment of the vibrancy, clarity and sharpening. Once I had completed that I created a duplicate image and reopened the duplicate in NIK HDR Efex Pro 2 where I used the Black and White preset to convert it. I then applied a yellow filter which enhanced the highlights and deepened the shadows.

The image below is the color version that I started with to create the Black and White photo. With this image I am showing you that there are sometimes several ways to create a memorable image by taking advantage of the tone mapping ability of NIK HDR Efex Pro 2 and then applying different presets to the final image.

I think the composition is strong in both the images due to the perspective and the leading lines taking the viewer’s eye down the corridor to the lights in the background. The HDR process allowed me to capture the detail in the structure and the barrels which would not have been possible in a single exposure.

Keeneland Concours de’Elegance

HDR Efex Pro 2 Packard image
Blue Packard

I took a trip down to Lexington, Kentucky this past weekend to the Keeneland Concours de’Elegance auto show. I have always been interested in automotive design and an event such as this one allows me to see firsthand the craftsmanship and beauty of our automotive heritage.

This Packard caught my eye with it’s massive headlights and brilliant grillwork. I decided to shoot this image as a bracketed series of images in order to overcome the wide range of light that the dark car and the brilliant chrome created. I knew that I was going to finish this image as an HDR image when I shot it. I monitored my histogram which showed me that I had the full range of tones in four exposures which would result in a good HDR image once merged and tone mapped.

Back home in the studio I merged the four exposures in NIK HDR Efex Pro 2 and applied the Structurized 2 preset as my base image. I adjusted the structure, black point and white point sliders very slightly before saving the image back into Aperture 3. I had to place a control point on the building in the lower right side of the frame and increase the exposure on the stonework to keep it from being a dark distraction in the composition. Once the image was back in Aperture 3 I cleaned up some sensor spots that had been emphasized by the tone mapping and hdr conversion before adjusting the vibrancy and sharpening the image for final output.

The composition is a pretty straight forward rule of thirds and uses the repetition of form to unify it. That along with the complimentary color scheme of blue and gold makes this image work for me.
