The exposure meter stops the exposure values and stops evaluating until the end of the shot. If you want to use the AE block with the example above, you should point the center of the frame on the face of our subject, press the asterisk key to block the exposure, put it on fire.
With the selected AF point, recompose and shoot. In this way we would obtain a result very similar to that obtained using the evaluative measurement. It ‘s true that it is a more complex way but remember that the evaluation would give a big importance to the face but would take a little’ account of the rest of the scene and if we were exclusively interested in the face the spot measurement would be more accurate thanks to Editorial Retouching Los Angeles.
AE lock can be used regardless of the shooting mode.
