Re: Everyone is overlooking the obvious


In rapidly changing light where the subect may be in very different light than the rest of the scene spot metering is defintitely your friend. You set your exposure based on the subject. Say for a a caucasian face dial in +1/2 or +2/3 exposure compensation and choose either AV or TV and let the camera do the rest of the calculation. No matter how the light changes or how rapidly your subject will be properly exposed. A 9% is just not capaable of this accuracy as it will include to much of the background thus affecting the exposure for the subject too much. This is how the pros do it - the experience is applied to knowing far away from 18% grey a they want to place a subject, not what the overall exposure should be - especially true for rapidly moving lights ina club or concert setting. (This is another great advantage of the 3, 1V & 1d - spotmeter linked to focus point - givig proper control over exposure focus and composition). If you rely on autobracketing is situations like this you may very well be off exposure on the shot you really wanted so that is definitely not an option.


Sorry, but you are not going to convince me a spot meter is the
salvation of any situation where lighting is changing once a
second. This makes no sense.

In low light or rapidly changing light, once you establish your
baseline exposure, any pro shooter I know would make any "once a
second" changes based on their experience (IOW a damn good guess)
and maybe auto bracketing if available and applicable.

There is not time to calculate exposure once a second. With any
meter, spot or not.
