"The Color of Truth"
Season 1, Episode 6
From all season 1 episodes, this is the least visually generous as Sam is wearing the same rather dull brown suit for its entire run. Additionally, the DVD transfer of the episode isn't particularly good either. I did manage to catch some nice shots, nevertheless. Here goes part 1 (click images to see full size).
For the second part, check out The Color of Truth Part II
