And not the final word!
If you haven't read this month's (October 2004) Outdoor Photographer, then pick it up. In it, there is an explanation about the different CCD sensors used in DSLR vs. Advanced Compact Digital cameras (specifically, the new 8 megapixel ones). The advanced compacts have a CCD sensor that's about 9mm across. The DSLR's have sensors that are about 24mm across. The main point of the column was the size difference in the sensors. But they also made the point that "the larger sensors are better at gathering light"!
To illustrate this, I took a series of shots last night. All shots were taken at 280mm (35mm equivalent) and f7.4 (the smallest f stop at that focal length.
The sunny f16 rules says that 1/250th of a second should be over-exposed by at least one stop. Hmmm. Maybe not.
First shot is 1/250th of a second (roughly sunny f16). Second shot is 1/125th of a second. Third shot is 1/60th of a second. Fourth shot is 1/30th of a second.
Brackett, brackett, brackett. Once you learn what works for your setup, then you can refine your exposers to a narrower range.
