perhaps I oversee something. But I have problems with my Canon 5D MkII in live view. I would like to use the histogram overlay in live view to see whether my exposure setting is good.
My general setting is "Stills+movie" and "Movie display". This works fine most of the time. But if I need longer exposure times than 1/30th of a second I change to "Stills+movie" and "Exposure simulation". I then have the following effect if I change nothing than the live view setting: The exposure meter reading stays the same but the histogram is shifted about 2 gridlines to the left and the live image in the display gets a lot darker. If I expose the image it is well exposed as the exposure meter indicates.
This is pretty annoying, because I can't use the histogram to see in LV whether I'm ETTR enough before the exposure as it works smoothly with the "Movie display" setting.
To say it again differently: I would like that for exposure times longer than 1/30th of a second I can use the histogram overlay in live view in the same way it works with "Movie display" for times shorter than 1/30th of a second.
What do I (or my camera) wrong?
