Not something you see every day
Graffiti? In Singapore? Never…
But it’s true; spotted this in the underpass under North Bridge Road. (Not sure where the greenish cast came from, though… possibly it’s an artifact of the iPhone’s total lack of white balance control.)
Edit: Found the answer! Sixth comment in this photo.net thread: fluorescent light has a varying colour cast at different points in the AC power cycle. If you shoot under fluorescent light at faster than 1/60th, you’ll get a random colour cast.
