Experimenting with "lesson of the month" tips on fireworks after a baseball game. Changing ISO to 50, manual focus and white balance to daylight as advised improved the color result enormously. Smallest ap. for camera - f/8 (for 3 secs) so a bit too much light. Greater lesson learned: A REAL photographer takes a tripod everywhere... I used my knees for stability, crossed my toes and held my breath.
