B&W Infrared HDR

As I talked about in my last post, I've been experimenting with Nik Software's HDR Efex Pro.  Today I used it with some images taken with my IR converted Canon 20D.  When using the 20D I'll use AEB (Auto Exposure Bracketing) anyways, usually +1/-1 stop, because you're never quite sure what will come out when shooting in IR.  I ready like the way it brought out the texture in these high puffy clouds and IR is somewhat surreal to begin with (just not too much) ;-).
