I tried some photography the other day of dripping water drops into calm water as well as "firing" it out of a syringe. I took over 100 photos and trashed the whole lot. I dumped because they are all out of focus. The only reason I can see for them to be out of focus is that I'm using macro. The lens I'm using is a Nikkor 35-70mm f2.8 that has built in macro. My problems are: How do I get good depth of field; and: What can I use to trip the camera because they way I'm doing it will take 1000's of shots to get what I want.

Thanks in advance.
