cliché or cliche (UK /ˈklʃ/ or US /klɪˈʃ/) is an expression, idea, or element of an artistic work which has become overused to the point of losing its original meaning, or effect, and even, to the point of being trite or irritating, especially when at some earlier time it was considered meaningful or novel.[1] (source Wikipedia)

Too often we photographers fall into the trap of shooting the same type of images that we have seen for years. With automobiles and car shows we will often shoot the entire car or some detail like a hood ornament, etc. I suggest you try moving beyond those cliched shots and approach the subject with an abstract approach that still speaks to the essence of the subject but isn’t so obvious.

In this image I fell in love with the bright yellow paint and the complimentary red and blue accents. I chose to use them as leading lines that reinforced the diagonal pattern of the clouds above the car. The blue sky is a direct compliment to the yellow color and also picks up on the blue pinstripes on the red louvers as it also provides background interest to the composition . While there is no question that the subject is an automobile the overall effect is to emphasize color and composition instead of being just another photo of a car.

I used my regular HDR brackets +2, 0 and -2 EV and processing with NIK HDR Efex Pro 2 which allowed me to capture and emphasize things such as the texture in the clouds and the reflections in the the door. I finished the image in Aperture 3 using some minor adjustments to the blue and yellow color channels, cropping and sharpening.

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.

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.

This is a three exposure HDR using NIK HDR Efex Pro 2 for the merger and tonemapping as well as some exposure and structure adjustment. The three kayaks in the scene are from the middle value exposure which is the default frame for NIK HDR Efex Pro 2 when anti-ghosting is applied; I used a 60% setting which seems to work very well for preventing ghosts when objects in the scene are moving in one direction. The anti-ghosting also worked very well for the women walking along the landing at this 60% setting. After completing my NIK HDR Efex Pro 2 adjustments I returned the image to Aperture 3 where I adjusted the separate color channels to get the image I wanted.
