Focus on Fireworks

This year for the Fourth of July fireworks I tried a new technique that I read about in several various posts around the web. The basic premise is to use focus to create blur around a fireworks explosion. I set my focus at just short of infinity and then refocused after tripping the shutter. I used shutter speeds of 1 and 2 seconds at f5.6 and f8 to experiment with this technique.

I finished all the images in Aperture 3 and really cranked up the sharpening both in the RAW file and in the finished image. I also played around a lot with the Saturation, Luminance and Range sliders in the individual color channels to intensify the colors.

All in all I am better satisfied with these fireworks images than any I have attempted in the past. I think I’ll work on refining the technique the next time a fireworks opportunity presents itself.

Remember to Look Behind You

Big Four Bridge at Waterfront Park, Louisville, Kentucky

When I was down at Waterfront Park, the night before last, I was there because I expected some dramatic clouds and colors at sunset due to the thunderstorm that had passed through Louisville an hour or so before sunset. I had consulted my cloud map and it looked promising, based on the wind speeds and direction, for some dramatic skies. I set up my tripod facing west and captured some incredible images of the downtown bridges. The wind was kicking up and the remnants of the storm were scudding across the sky. I happened to turn around to look at the Big Four Bridge where I saw this scene unfolding.

Because the clouds were moving so fast I knew it was futile to try to bracket the shot so I looked at my histogram and started firing test shots. Once I had dialed in a setting that gave me a slightly underexposed histogram I just started firing the camera. I know from experience with scenes such as this that the biggest pitfall I face is too much light in the highlight areas which is why I chose a slight underexposure setting. I shoot almost exclusively in Aperture Priority mode in order to be able to predict and control my depth of field and this evening was no exception. I was using f9.5 and letting the camera choose the shutter speed based on the exposure value I was using. The clouds were moving very fast and I shot around 20-25 frames before they were no longer in a position that I liked.

Once I was back at the studio I started going through the images from this scene and chose this one for the position of the clouds and the way the golden hour light was shining on the bridge. I opened it in Aperture 3 and straightened the horizon before sending it into NIK HDR Efex Pro 2. Once inside NIK HDR Efex Pro 2 I started looking at the various presets and tried the Realistic Deep preset that I like to begin with for most landscape shots. I didn’t particularly like the effect it was having on the clouds so I switched to the Landscape presets where I discovered the preset I felt gave the best results. I then started adjusting the tonal range and structure until I had brought out the detail in both the clouds and the bridge. Once I was satisfied with the basic image I returned it to Aperture 3 where I further enhanced the color using the Vibrancy adjustment, along with the Exposure panel controls, to fine tune the image. Finally I adjusted the sharpness slightly and saved the image.

My point with the title of this post is that too often we photographers are focused on getting a particular image that we have in mind and fail to see the other great opportunities that are around us. As photographers we need to be “present in the moment” in order to capture the mystery and beauty that surrounds us. This whole scene came and went in a matter of minutes and there is no way that I could have foreseen this situation. If I hadn’t taken the time to look back behind myself I would have missed what I think is a dynamic and powerful image.

 

 

Vendome Copper and Brass Works, Louisville, KY

Yesterday I downloaded the newest version of NIK HDR Efex Pro 2 which just came out this week. I had seen a webinar by NIK that showed the newest features of the app and I wanted to try it out. I am very impressed with the upgrade; the new version is much more refined than it’s predecessor which I already thought was the best HDR app I had used.

Today’s image was taken at Vendome Copper and Brass works here in Louisville. Vendome Copper and Brass Works is the main manufacturer of distilling equipment in the USA and the opportunity to photograph there was wonderful. They use a lot of copper to build these stills and distilling columns which made the place a fantastic place to photograph. I have several more images that I took while there and will be sharing them over the next few days.

This photo was processed from 5 frames taken at +2, +1, 0, -1, -2, Exposure Values. I could have just as easily used shutter speed to bracket the shots but my method is to adjust EV when shooting HDR brackets. I then took the images into NIK HDR Efex Pro 2 where I merged them and then applied the Realistic (Deep) preset and did some minor tweaking of the settings. After that I returned the image to Aperture 3 for sharpening and final output. If you are looking for an app for HDR processing I highly recommend NIK’s app, like everything else from NIK it is loaded with features and performs flawlessly.
