Infrared Trees, Tower Grove Park

A high contrast version of this picture posted earlier as Infrared Tree Abstract #1. In the post, I mentioned a Photoshop tutorial on the Life Pixel web site that explains how to process digital infrared captures.  The picture I posted, however, ultimately had very little to do with the tutorial.  I also had a few questions about the infrared processing, so I thought I'd post the intermediate steps.  This picture is a more conventional monochrome conversion with a sepia highlight/blue shadow split tone, much like a print on Ilford Multigrade FB that has been bleached in Farmer's Reducer then toned with Selenium.     

Above left is the straight color shot.  Center was shot using a Cokin P007 infrared filter.  On the right is the output of the center image in Photoshop after applying a custom white balance and swapping the red and blue color channels. 

Here is a runner up version I like quite a bit.  It is based on the color corrected output, processed as a Polaroid transfer in Nik Color Efex Pro, then a split tone applied in Lightroom.
