I spent last week in the Shenandoah Valley of VA. It was a very early cold spell. My 1Ds II could not handle the cold. Luckily my converted 20D kept right on going. These are from the McCormick Farm. -Tom
I'm a little torn between leaving the IRs in the red channel or converting to the blue channel. Here's one I switched. It seems like a tug of war between drama and prettiness. I guess they both work okay.
