I've played around with taking water drop pics before and I guess the first time I did it, I just happened to get lucky right from the start. I've re-visited this over the last few days and just can't re-create it. I'm shooting now with a Sigma 70mm Macro at 1/180 and f/8 to f/16 with an alien bee strobe at about 1/32 power. For focus, I have the water bag hanging above so that it hits in a constant location then put a pen or something in the same spot, focus on it then set to MF so it doesn't hunt. My problem is that I just can't get the sharpness that I would like and something similar to what I had in this picture. When you guys are shooting these, what lens and settings do you use? Did I just get lucky in the first round and it's really just a crap shoot and you pray and spray and keep shooting until you get a sharp one?
