Today was a bit tough on ideas. But I am not giving up easily. 5 images alltogether go in here.
What I’ve learned today is that flash is a kind of hot after it flashes. Interesting effects can be obtained by closing the flash with different things (paper, hand, etc) in a small room (like bathroom). Also, a polarizing filter can be used without bright sun and reflections – it does decrease the amount of light passing through the lens producing interesting results. This calls for more experimentation though.
