Thanks for the comment Prin.
I should say one thing though about the tip on using windowlight. It's OKAY if direct sunlight is coming in from the window. It makes for a dramatic shot.
It's just that it's HARDER to control the exposure, and the colours may washed out because the film or digital sensor can't handle the brightness.
All that to say - it's easier and more predictable to use softer diffused window light.
