Interesting, you do get even more contrast. Not a lot of clouds in the sky right this moment.
Also, with the polarizer on the autofocus stopped working. I switched to manual, and this one photo turned out super sharp. I wonder if the autofocus is a bit off with the IR. Experiments needed.

thats what they are (mostley) used for in photography
I can confirm this behaviour for my IR-modified Exilim. not always but most of the time (I think the Contrast-detection autofocus doesnt work well with the slightly "blurry" IR)

720nm. I need to get a higher wavelength filter.
Just ordered this set. Only $40!

I got my longer filters today. There's a strong difference between the 720nm and the 950nm, which lets through less light (obviously).
The 950 gives more contrast between sky and vegetation, but less contrast within vegetation, so the trees look more white and washed out.
720 left, 950 right, drag to compare.

950nm really needs a tripod. It gets a slightly higher contrast sky, but often ends up a bit blurry.
I switched to 760nm, which seems like a reasonable compromise.
Really though, I've not sure seen a huge improved in close-ups of planes leaving contrails. Maybe a bit clearer, but it's hard to get an exact comparison.
