John, I might interpret these points incorrectly. I am however, not sure if I can fully agree with all of the points made.
Point #1: Flash is not used to increase shutter speed in low light. Flash is indeed the “shutter speed” when you use flash. Flash can be used at any shutter speed below maximum sync speed and it will freeze action. That is the reason the technique of “dragging the shutter” is so effective.
Point#2: Not really a reason for using flash in low light. If shooting in low light with only static subjects you can increase DOF without using flash.
Point #3: Flash WILL FREEZE ALL subject movement. It will not merely help freeze movement.
I do not understand #4 either. How can flash reduce the time between successive shots. With or without flash my D200 can run bursts of 5FPS. Depending on the strength of light needed by the flash, to properly expose the subject, either only one shot will be properly exposed of all five shots will be properly exposed. Flash does indeed slow down the time between successive shots.
Reasons against:
Point #1: When tripod and a slow shutter speed can be used you can get amazing shots by “dragging the shutter”.
Point#2: That is common sense.
Point#3: If flash changes the atmosphere of ambient light you simply do not know how to use flash.
Point#4 is the only point I can wholeheartedly agree with for the same reasons you mentioned.
Please help me out here, am I missing the Flash Bus?
