Trees, Infrared HDR Test #1

While I had the camera out this morning, I thought to make a quick set of brackets to test infrared HDR.  This is the final shot, using Lightroom to make the monochrome conversion from last picture in this post, with an aqua/sepia split tone and film grain like Ilford HP5.

This is how the base exposure looks.  The Nikon D700 is not very sensitive to IR light, so I use a +1 stop exposure adjustment for the two over, two under brackets.  The first step is to combine the brackets using Photoshop HDR Pro.   

The next step is to apply a custom white balance and adjust tone of the HDR image, both of which I did in Lightroom 3.  The new Lightroom 3 develop preset "General - Auto Tone" works very well for the tone adjustment.

Then it is back into Photoshop CS5 to swap the red and blue color channels.  This picture now looks very much like it was shot with KODAK AEROCHROME III Infrared Film 1443.
