The aperture was varied (f4 on the 1/200 shot to F/32 on the 1/6 shot), the ISO was constant 1600, to keep the exposure constant. They were all shot @ 200mm on a 1.6 crop camera (the final images were also cropped)
I agree you are going to run into real problems for short streaks (high shutter speed) along with a lot of DOF (small aperture) as there is not a lot of light when it it is raining.
Shooting wider would help.
Possibly using a P&S would do also the trick if high ISO noise is not a problem. I amy run more experiments, depending on the weather.
