Lunar: Tycho, Plato and Wilhelm

Hi all

I captured these on the 30th December 2007 and only just got around to processing them.

For something different (for Tycho and Wilhelm), I tried a HDR approach - capturing 2 avi's; one which had the highlights overexposed, and one which was slightly underexposed. I processed them both identically, and combined them using layer masks in photoshop - similar to how we do it to reveal the core of M42 with shorter exposures.

It allowed me to get the histogram just right and have a better dynamic range without blowing out the highlights. It seemed to work fairly well and is something i'll do again in future when the subject needs it.

On Wilhelm, I like the banded contrast across the crater floor, due to the rays from Tycho splashing out.

MAP processing, about 200 frames stacked on each alignment point (between 4-8 alignment points).

Thanks for looking.
