Room with the view
Lots of bin bags for the windows, a +0.25 converging lens from my optician allows light to hit the wall focused at 4m (to form a camera obsura) but at the same time providing a larger aperture for more light. I blocked off all the light hitting the ceiling & floor to provide the most contrasty image possible. Nevertheless it’s hard to see much colour when your are actually there.
The sunlight was best in the late morning when it catches the windowsills of the pink building. In all the exposures were shorter than I expected, the cameras histograms help determine the perfect exposure time.
Additional details can be found at:

The definitive photographer:
Camera Obscura - Abelardo Morell
ISBN: 0821277510
I would be interested to know, if anyone has found a supply of +0.1 & +0.2 diopter lens?
