I would like to share some setting which i use in my Olympus E-510 to take those fireworks shot.. 1. iso 100 2. manual focus set to infinity (my fren using canon s3 set to autofocus ruin all his shot!) 3. 4s to 8s (dont be mistakenly set to 1/4 if u r using nikon d40x as what happen to my fren) 4. F8-F11 5. Noise Reduction must be on for olympus camera (i learn this the hard way) 6. Tripod 7. Remote Control ..if dont have also nevermind just be smooth when u press the shuttle Those are the main things to look out for..With those setting you can definitely get 1 or 2 usable shot.. good luck..
