I have been wondering lately about a pretty common tip in various photo-situations. Namely to turn down exposure compensation. What, if any, is the difference / benefit in doing that instead of just choosing a shorter shutter-time or narrower aperture?

Hi Meh,

In situations where the camera is deciding the total amount of light that reaches the sensor and/or the ISO number then setting EC is just a way of telling the metering system it's got it wrong. Maybe you need to bring out detail in the shadows and you aren't worried about clipping the highlights or maybe you need to avoid any clipping even if it means the rest of the picture is potentially under-exposed. Obviously in situations where you have taken full control of shutter speed, aperture and ISO then EC has to be applied by you by adjusting one of those parameters.

Bob.

ah. So EC is meant for when you shoot in, for example Apperture or shutterspeed priority?
Thanks for the clarification.

I've gone fundamentalist so I only use the M-mode. The result varies a LOT but I assume it will get better. :lol:

Aye, in M the metering is up to you
in Av for instance stopping the aperture would just make the velocity go down since the target exposure was still the same and the camera would need to compensate, the EC just changes this target exposure
