We're trying something different this time in hopes of gathering more interest and participants. The previous rules mostly still apply with the exception of two things. 1, a Jeep is not required in this photo and 2, the submission timeline will extend to 9am on the 18th instead of just 7 days. Seeing how time of day dictates this one more opportunities may be needed. That being said...
A photo taken within 30 minutes of sunrise or sunset with the emerging or dwindling light being the contributing factor in the photo. Use this light to you advantage, rely upon shadows that appear only at that time, and try to seek out colors that you'd not normally see any other time of day.
Here are a few examples to get the ideas rolling...
