sample 37
brick (brown, regular, kalkzandsteen, that's the Dutch word for 
this kind of brick)

aperture 1 tick before 8 (quite open, it's a dark brick)

zooming in slightly to exactly between 90 and 60
doing also the calibration at zoom!

parameters z=360 p=18 l=172
photometer calibration at 2 times 5 sec.

the pictures don't look very sharp but i focussed and this is 
the best i can get. on the tv monitor the pictures look much 
sharper. i noticed earlier (last year) that this is always the 
case with bricks
