Today I just played with my lights in our garden. It was shortly after rain, so it was very wet and air humidity was high. But light color seemd too bluish to me than before.

So I took my camera and made some beamshots and compared them with some older ones. I used exactly the same exposure settings(2.5s, iso 80, f 2.8) and white balance. Both lights have normally warm or yellow tint. But in wet conditions they look more like blue or purple tint.

Has anyone noticed the same thing? Do you have some explanation:confused:

think of water droplets to work like prisms....
I have yet to figure out how to leave water droplets at maximum surface tension oval enough for me to use it as an impromptu aspherical lens:grin2:
