I've been busy this week, updating some digital images that I made of the planet Mercury a few years ago. In this series, I used original captures made by the Mariner 10 robotic space probe in the 1970s, and did a lot of heavy post-production work in Photoshop.
There's more information about Mariner 10 -- and several original images! -- at Wikipedia:
