There's a series of articles beginning from Izumi Taniguchi on how to use the Pentax Photo Browser and Pentax Photo Laboratory.
The manual that ships with the camera is rather skimpy and does not explain a lot of things like:
1. random noise reduction
2. spurious color signal noise reduction
3. tone curve
etc
Besides elaborating about the softwares' features, Izumi also offers tips on better digital photography with special tips for Pentax camera owners.
Izumi's posts are bound to enlighten all new Pentax users.
