Re: Photographing Rain
Hi, you could follow the way of the Japanese master Hiroshige. http://www.bbc.co.uk/paintingtheweather/csv/painting/shower.shtml He scratched the printing block. You could scratch your negatives. -- Cheers, Bob > On Thu, 2004-01-08 at 16:22, Shel Belinkoff wrote: > I want to catch the rain falling in a photograph. My attempts at this > have all been failures.

Re: Photographing Rain
The first thing to do now that it stopped raining: wait untill it starts to rain again, else you might be dissapointed about the results On Thu, 2004-01-08 at 16:22, Shel Belinkoff wrote: > I want to catch the rain falling in a photograph.

Not sure whether that was the question, or whether he meant to ask about the speed of raindrops in different storms. The size of the raindrop will affect its terminal velocity (shape too, but in the case of raindrops that's determined by the size anyhow), so small raindrops will fall at a different speed than large ones. An example of the extreme case of this: if the drops get small enough, they barely fall at all, and you get mist instead of really rainy rain. As BR pointed out, all of this goes out the window in a vacuum (yeah, yeah, imagery inadvertent but cute enough to leave in anyhow), where size and shape no loner matter and there's no terminal velocity so things keep accellerating until they hit. Completely off-topic trivia: terminal velocity for a human (in air, in Earth gravity) in spread-eagle position is somewhere around 70 MPH. I'm not sure, but I think I heard it's about double that for a streamlined headfirst dive. (And a Hell of a lot slower after pulling the doohickey that lets the parachute open, of course.) -- Glenn

The best (most expressive) pictures I've seen have been taken on sunny days (!) with the rain backlit to show up as light streaks against a dark background. Speeds of 125 down to vary the length of the streaks. If you can't get it backlit against a dark background (or even if you can) adding a little milk to the rain increases its visibility, according to Gene Kelly. mike -- Founder member, The Secret Pentax Society of twited pigs
Re: Photographing Rain
Rain, down where you would be photographing it, will be pretty much falling at a constant velocity. Gravity (constant acceleration) is only for the case of objects falling in a vacuum. In a fluid (air) an equilibrium is reached between the force of gravity and drag. The velocity the object reaches is know as terminal velocity. To get the rain drops to show up well you have to light them. You dont need flash, but you do need light. Have the light come from the side so it doesnt reflect straight back, or light up the foreground. A high powered flash light might even do.

Something like if you have "Scratched out". Is a effect provided by the movement os the drops while the shutter is open... []'s, CN > What's a "risky" rain?
