Enceladus: A problem of contrast

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.
