Sparks Were Flying

I love it when sparks are flying! Whenever I see someone using a torch or a grinder I try to capture the spark patterns that are formed. It is as if the worker is putting on a miniature fireworks display and the kid in me cannot resist watching.

This HDR image was created from a three frame bracket set of +2, 0 and -2 EV exposures using NIK HDR Efex Pro 2 to merge them. After merging the three images I applied a custom preset I have built and saved in NIK HDR Efex Pro 2. I then returned the HDR file to Aperture 3 for final adjustment and sharpening.

One thing I discovered in merging these images was how through use of the anti-ghosting feature I was able to show how the gases used in the cutting torch could be isolated and show where they are pushing the sparks away from the torch.
