Can you guess what this is..... Yes, the title gives it away.
I was on my 'ventalin' machine this morning, and noticed the wonderful light patterns on my wall and ceiling.
The lights patterns are actually coming through my timber blinds, over a window of another wall, at the front of the house, onto part of the side wall, as well as part of the ceiling.
I played with this quite a lot, with burning and selective color, to whiten the whites, and to darken the blacks, to get this effect.
A strong geometric 'light and shade' abstract image here, just from the wonderful light patterns on my wall.
