What do we observe in the infrared? Why do we observe in the infrared? Atmospheric transmission. Specifics of the data reduction in the near and mid-infrared and comparison to what we learned in the optical. Examples: two star clusters (NGC 2244 and RCW 38), images taken in the K-band with HAWK-I/VLT; Galactic Center in the L-band (NACO/VLT). Strategies for sky subtraction; chopping and nodding.
