Dramatic Clouds in HDR

Last Saturday morning I went down to Waterfront Park for an event on the river. The sky was full of dramatic clouds that really captured my imagination. The weather was rather raw and the turnout was low so I decided to take advantage of the ominous looking clouds instead. I thought the clouds would be good candidates for HDR images so I shot three frame bracket sets of each scene.

I decided to process the bracket sets in NIK HDR Efex Pro 2 first and then returned them to Aperture 3 for some contrast, straightening and color channel adjustments. I then took them into NIK Viveza and played around with some very minor tweaks to them. I liked the results and the way even minor adjustments in Viveza had great impact on the resulting images. I even took one version into Topaz B&W Effects where I applied an antique style effect that I created a few weeks ago for another series of images.

Back to the Sprayground.

Yesterday’s post about the Louisville Waterfront Park Sprayground was very popular so I decided to add another shot from that shoot today. Using HDR techniques I was able to expose for the bright sky and clouds as well as the people sitting in the shade watching the kids at play. I especially like how the water fountains were rendered showing the water splashing on the pavement and glistening in the sun.

I shot a three frame bracket set -2, 0 and +2 EV. Even though the kids were running around NIK HDR Efex Pro 2 and it’s anti-ghosting feature kept the ghost artifacts to a minimum. I especially like how the water fountains were rendered showing the water splashing on the pavement and glistening in the sun.

This is another case of shooting during a part of the day that is usually advised against, though by breaking that convention I was able to get a very realistic shot that has a feeling of playfulness and spontaneity that is in keeping with the subject matter. Through use of repetition of shapes and color I was able to come up with a very active composition. While framing the shot I included the blue sky and clouds with the green trees to emphasize the texture in both areas. In the foreground the blue astro turf and the natural grasses and wild flowers serve to reinforce the upper part of the frame. The diagonal sections also contribute to the active space and serve as reinforcement of the kids and fountains as the sprayground recedes into the background in a dynamic diagonal swoosh full of action.

With all the blues and greens that dominate the pallet the brilliant reds that appear throughout the middle of the frame serve as counterpoints and add interest to the cental area of the image. I included the figure in the right foreground to suggest that even outside the frame there is action going on that warrants attention yet she is still connected with all the other folks in the scene.

Today I am going to share several versions of one image to further illustrate the HDR process. In the image above I combined 5 exposures using NIK HDR Efex PRO 2. I then started with one of the realistic presets in NIK HDR Efex PRO 2 which I adjusted to my vision for the image. After getting it where I wanted it I created a custom preset that recorded all the adjustments I made to the image. I named the custom preset Pine Mountain #2 and saved it in the custom preset panel in NIK HDR Efex PRO 2 so that I could use it with any image I chose. I then started applying it to some of the single frames from this scene.

I’ll start with this frame which is the -1 EV underexposed frame. As you can see it is very dark and lacks detail in the shadows.

Below is the same image with the Pine Mountain #2 preset applied. It opened up the shadows and brought out a greater color range as well as some shadow detail.

I followed the same process for the 0 EV exposure below. This exposure has better shadow detail than the underexposed frame but it is beginning to show some blown highlights in the upper area, notably the small amount of sky and the mountain laurel leaves.

Once again I applied the Pine Mountain #2 preset I had created earlier to this single frame which produced the image below. There is now more detail in the shadows, the colors are richer but the sky is starting to gray slightly.

Lastly I used the overexposed image with the +1 EV and followed the same procedure with it. Once again the highlights are blown in the sky and on the leaves as well as on the rocks themselves.

This is the overexposed image after applying the Pine Mountain #2 preset.

Once again there is marked improvement both in the highlights and in the shadows but it still isn’t as rich as the first image in this post that was created by merging multiple exposures in NIK HDR Efex PRO 2.

My conclusion from this experiment is that; while there is increased detail in the shadows, better highlights and increased tonal range available when using NIK HDR Efex PRO 2 on a single image; the use of multiple exposures produces a richer more detailed image. I stand corrected regarding my earlier post about the differences in single vs multiple image HDR processing and the results that are attainable.

I hope this helps my readers and that they benefit from my exploration and experimentation with the NIK HDR Efex PRO 2 software. I feel certain that these results are repeatable regardless of which software is used be it Photoshop, NIK, Photomatix or any of the myriad of other HDR programs out there.
