This color for this shot was directly out of the camera. I only tweaked the contrast.
If you look at the data this image was shot at: the ISO at 125, F5, at 1/5 of a second is was shot at a slow shutter speed.
Many photographers think you need a fast camera to achieve a shot like this. It's all about timing, location and setting the image up correctly in the camera. It is also wise to have a camera without shutter lag. That is why I use a Nikon D3.
Actually, according to my computer lighting scanner, this strike was about 15 miles from my location though a spoke of this lightning could pay me a visit at any time. I don't take any unnecessary chances. One poof, and it's all over.
