Actually now I am beginning to question if there is a flash mounted on the camera whether or not it behaves differently in Master or Controller mode. In my test shots I can not find a difference in the lighting. It seems like it is always in Master mode. This isn't true if I use the pop up flash. Same for my K20D and K5. The custom option (#21) says "fires the
built-in flash as ...
In your example did you try setting the on camera flash to Master and Controller to see if you experience a difference? (nice examples by the way).
The K20D doesn't increase flash output of the remote wireless slave when I point the on camera flash to point toward it.
I usually use cybersyncs when I use flash anyway but would like to use P-TTL and wireless if it was reliable. Sigh, oh well. Everything can't be perfect.
