How Do You Photograph Rain?
So how do you make rain appear in pictures? The solution couldn't be any simpler - backlight. And that simply means any light source positioned at the back of raindrops. It doesn't matter what angle. Take a look at the following picture showing how water from a garden hose (to simulate rain. Natural rain fall is very rare in Doha.) is backlit by one Canon Speedlite.
I've included some setup and test shots here for your reference. Some of the results we liked, apart from the one featured above, may be viewed at Lighting Adventures.
Some addiditional advise if you are planning on doing a similar kind of shoot.
1. Be considerate. Plan well ahead of time how you intend to execute your photoshoot.
2. Turn off the water tap each time you pause to review your shots and re-think of your strategy.
3. If possible, do your photoshoot in the softscaped part of your garden so the plants and lawn may benefit from the water you are throwing away. Keep shooting on hardscape to a minimum.
