How much do you shake your card?
if i shake my card in minimal up-down movements near the horizon, my building above the horizon becomes dark while the part below the horizon is exposed ok.
I try to shake the card with respect to the height of the building in such cases, but there's no fixed method of shaking. It's something you discover as you go along, haha! Quite a lot of trial and error, actually. Most of my shots needs a few attempts to get the exposure that I'm looking for.
Love your pics and the expert use of the black card technique. Were u at Labrador Park over the weekend? May have unknowingly met u.![]()
Thanks.

I figured December/February period would be much better though, the sun will be somewhere at the right. Then I thought about Bishan and totally forgot about this place. Probably because I live much nearer to Bishan and sometimes lazy to get up early. hahaha.
Ah, that would be nice. The buildings would then be pointing towards the sun!
