I know very little about Dale Martin – except for his work. I constantly follow his work on 500px, and click over to his Flickr photostream every couple of weeks as well.
He shoots professionally, and focuses on cars. Most of his photos are individual shoots, rather than event coverage.
His post-processing work is better than a lot of other photographers and looks like it came straight out of a magazine page. If you shoot cars, you should review his 500px portfolio and see how he makes his photos top quality.
Focus On is an showcase where I spotlight other photographers/artists/forums/individuals that I follow and learn from, as well as companies, tools, and applications that I use.
