 After a couple meetings with Walsh Construction I have been granted access to the construction sites after I complete the required safety training.  This week I will be going through safety training with Walsh Construction to familiarize myself with the safety procedures that I will need to follow while shooting the Ohio River Bridges Project.

I am excited and honored that they are allowing me to shoot onsite and really looking forward to getting started. It is a huge project and has over 50 individual spans that I will be following for the next three years as the project proceeds. I will be able to document the progress and the men and women who are building the bridges from now until the completion of the project.

I hope you will stick around as I record the day to day work that goes into a project of this scale and the men and women who will be doing the work. I intend to show as many facets of the job as possible from the construction workers to the engineering support teams and the folks who run the office side too. I’ll be shooting most of the work in HDR and I’m sure that there will be many discoveries as I try new software and new camera techniques throughout the next three years.

Using OnOne Perfect Photo Suite 7.5 with HDR Images

I took an HDR image that I created in NIK HDR Efex Pro and started experimenting with it in OnOne Perfect B&W to see what I could get from it. The OnOne Perfect Photo Suite is very powerful. It allows me to work in layers so that I can turn on and off each individual layer to see whether I like what it does in conjunction with other layers. For the first image here I applied the Ambrotype preset and then made several adjustments to the paper tone and silver tone, added an Emulsion border and adjusted the contrast and sharpening. Using the HDR image as a starting point helped render the interior details while still maintaining the surface textures on the car.

This is the HDR image I started with. As you can see there is a lot of color in the image due to the patina of age. Most of the color in the glass and the wooden steering wheel was too muted for my taste until I adjusted the separate color channels in Aperture 3 after merging my bracket set in NIK HDR Efex Pro 2.

For this last image I used the Perfect Effects application and applied a preset that changed the overall color of the image yet allowed me to emphasize the yellow and red in the window sticker. I can’t recall which preset I started with but I’m sure that I adjusted it’s effect to get the result I was looking for. I seldom stop with the base settings in these presets as I consider them to be starting points rather than end results.

The point of this post is to show that digital image processing opens the door to many options when creating art photography. It’s no longer necessary to spend hours in Photoshop building an image only to discover that it doesn’t convey your vision for the piece. By applying plug-in presets the artist is able to look at variations rapidly and decide what they want final result to be. Once a preset has been selected the artist can then make their own changes to it and emphasize the aspects of the image that are important for their vision of the image.

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. 

 

Louisville’s Downtown Bridge Is Underway

This is another HDR image of  Waterfront Park looking west toward the crane that will be part of the skyline for the next couple of years. I shot this from the ramp to the Big Four Bridge overlooking the Swing Garden. I shot a handheld bracket set of three frames +2, 0 and -2 EV. I was able to hand hold the shots because it was mid morning and the light was high which resulted in relatively short exposures.

I first took the three RAW frames into NIK Sharpener Pro and applied adaptive sharpening to all of them. I then opened them in NIK HDR Efex Pro 2 where I merged them and applied  the Deep 2 preset which I tweaked a bit to reduce some of the luminance and saturation. I then returned the merged image to Aperture 3 for final adjustment, sharpening and added a small vignette. In Aperture 3 I also adjusted the exposure and contrast as well as tweaking the individual color channels in the green, yellow and blue areas.
