I want to submit the idea that the EXIF data, which is good for a photographer to keep records of his or her own work, is meaningless to anyone else.
Photography is about light and being there at the right time to capture that light. Ansel Adams was always asked what settings he used for a particular shot and he would answer something off the top of his head, like, "2 minutes at f/64!" The point was that the settings didn't matter nearly as much as the lighting and the being there. To bounce off of that idea, I love the thought of just going out and trying the different settings and finding out what works. One person's settings will be meaningless to another person who is using different equipment in different light. Each photographer is trying to create his own art with his own vision, so others' info and data would be meaningless in helping someone create their own vision.
It's all about the light. As for rain drops, I still like the photos where rain drops are frozen with 1/2000ths shutter speeds with flash or sunlight, and also love the 1/15th speeds for long rain drop streaks.
