This is the Opportunity "Sol 1 Postcard" by Pancam.

This is a color composite from Pancam's blue (480 nm), green (530 nm) and near-IR (750 nm) filters.
Because the near-IR filter was used as the red channel, the image had to be color balanced to
yield a rendering of approximate true color as would be seen by a person at the Opportunity
landing site.  It's not a mistake that the scene is noticeably dark--this is the darkest landing
site ever visited by spacecraft on Mars! (reflectivity only around 10 to 15%)

Local Solar Time = 16:00 to 16:20 on Sol 1.

View is looking to the west-southwest.
