"I've never used a Clear filter, as it doesn't sound like it would be useful for me in the environements I'm in. Can such a filter darken washed-out desert skies?"
Here are a couple of before and after shots. One is straight of the camera, with only WB and Lens correction. The second has 20-30 seconds of editing, which can then be applied to an entire series of shots with a couple of clicks.
I was looking at a storm cloud today, with the sun just out of the frame to the right.
This has the "dehaze" filter applied at +30.
