I have been playing with light lately, both off camera flash and ambient lighting only . Here are two recent shots I have been playing with.
1/30 at f3.5
Only one light in the room, a table lamp about ten feet to the left of the piano.
1/60 @ f3.5
One off camera flash at 90 degrees to the left of the bulb. Three ambient lights one to the left, one to the right and one behind.
