I was at the 2015 WAAAM Traffic Jam, when a car club arrived from out of town (I can’t even remember where.) Among the cars was a 1957 Buick Roadmaster. Right away, I knew this was a very special car and it did end up winning several awards at the show. While I was there I made sure I got a pretty good number of images of this auto.
At that time I was processing most of my automobile and airplane shot through a Lightroom preset that brought the highlights down, the shadows up, and applied a lot of clarity. This preset tended to accentuate reflections and while I was working on these images, I became very disenchanted with how this made the paint job look. It pretty much ruined the color of it. So, I decided to change my method to something more like that taught by Tim Wallace at KelbyOne.
This post method is pretty basic as an overall treatment to the image. Then apply a considerable amount more clarity with the brush, to the grill, headlights, and other like items on the car. Sometimes, I even add some Tonal Contrast from Nik Software, Color Efex Pro4.
I am happier with this method. Not adding clarity to most of the automobile has the paint job looking much nicer. I do add a slight amount of clarity to airplane images overall, but a small amount that I add to most images that I make regardless of the subject.
I suggest you take a look at Tim Wallace’s classes for more information.
