Downtown St. Petersburg can be surprisingly good for spotting super cars and other exotics. For example last night parked right on Beach Drive NE was this blue Ferrari California. I was actually teaching a DSLR Photography Lesson at the time and used the car as a practice subject. Even if I was on my own and had all the photographer gear with me I would want, it would have been difficult to produce a shot any better than this due to the neighboring cars and the busy background.
So in making this quick car photograph I concentrated on the best detail clearly visible, in this case the front wheel and huge ceramic brake rotor and bright yellow brake calliper. There was still the problem of the street it was parked on being in the foreground (see below image).
After doing my usual editing workflow first in Aperture 3, then Color Efex Pro 3, I sent the photograph into Photoshop CS5 and did some selective edits (sharpening, contrast) before simply removing the car and wheel from the image and putting only that on a new layer. Then I added yet another new layer under the car layer, painted it white, and boom, produced the best image I could of a car in a very non-ideal location.
