I have a Canon S3 IS--which as I understand-I am not supposed to be able to do this with but....... I did. My set up is my kitchen sink, my camera and my choice of colored vessel, plastic etc. I have seen people use a colored towell for a background and a soda bottle with a hole punched in it -strung from a ladder, tripods, remote fire buttons, soft boxes and lamps--very ellaborate, but for me--sometimes I use supermacro--sometimes I set the ISO to High --successive shots -- find a good depth and start firing away-I use my strap and pull down on the camera to steady it. Nothing fancy --you do need large cards to do this---lots of shots--few are keepers--
This shot was done with an antique gold glass candy dish which is a foot high and the bottom of a tupperware cake tote (yes --primitive but it works!) I filled the dish with water then set the fawcett to drip--slightly fast but not a continuous stream. It's taken me several sessions but each time I try--it gets easier and the shots are better.....I just enjoy the challenge!
