Still learning the processing tools. This was part of a series of flames I'd taken February 3rd, but one that was not previously posted. Today, I processed it with Nik Color Efex Pro 4, within Aperture. Then re-processed in Aperture working with color levels and black point. I don't think I could replicate it but I'm starting to get a feel for the possibilities.
This is a different one taken the same night and not processed: http://365project.org/taffy/365/2013-02-03
@danielwsc Thanks! Processing is mostly my focus this week and I'm having a lot of fun with it. There are so many different looks to create from a single photo.
