I noticed two things right away: the glass with the droplets needed to be super clean and smudge free, and it was tough to get droplets of equal size and shape. I was getting a lot of blur and haze and runny drops. Naptime was over so I packed it up and loaded my shots to see what I had.
I shot this in full mid-day sun and was able to use a fast shutter speed, so I did not set up my tripod. I probably should have, but I'm often just plain lazy and nap time is way too short at my house. I used my 50 mm lens at f/9, ISO 50 and 1/200 sec and hand held my camera toggling my focus point.
I like the effect I got from the second set up much better. Had I had more time I probably would have tried to make the drops more round and evenly spaced. In editing I added a little clarity and selectively sharpened the spheres before resizing for the web. Here's another shot:
This was pretty easy and inexpensive to set up. I had fun playing with this shoot and will definitely revisit this idea, perhaps trying different backgrounds for different effects. Give this a try and link up your shots here. I'd love to see them and hear about your experience!
