Hi, I am using a Canon EOS400D , I would like to know the best settings to use for taking photos of water drops/raindrops, I have read so many articles,but I am still really confused.
This is pretty much a trade-off. Because raindrops are small I'd say it's optimal to
If you have a light source illuminating the raindrops while they're in front of a darker background, they will surely be more visible. An external flash from a different angle than you lens, only hitting the raindrops and not your background, could work.
Settings mostly depend upon the environment. For example was taken at ISO 100, F2.8 @ 1/400second. That was just a shot out of my window, after it had stopped raining and the sky was returning to a blue-colour.
If you want to use a strobe to highlight falling water, or falling rain, you'll want a similar shutter speed but you might find the aperture has to be smaller to avoid over-exposure.
