I have my Mark IV set up as follows:
2. Mirror Lockup
3. 2 Second self-timer
My problem is this: when I click on Start/Stop to show Live View, I see a simulation of what the shutter speed/aperture are set to.
As a result, when shooting flash, for example, and leaving the shutter speed at 1/125, the screen is virtually dark!
How can I set the camera to override the exposure settings and show me a Live View that is as bright as the scene?
