Live View on
The E-510 features the same Live View functionality as the diminutive E-410. To activate live view you simply press the Display button on the rear of the camera. You can change the image overlay in live view mode by pressing the INFO button. Below you can see the four default views followed by the three optional grid overlay views.
Changing settings in Live View
In live view mode pressing the OK button displays a semi-transparent settings overlay as shown on the left below, this not only provides a summary of current camera settings but allows you to navigate and change any setting you wish (as above).
Live View: Auto Focus
The E-510 provides for Auto Focus in Live View, it does so by closing the shutter and dropping the mirror so that the AF sensor can be used. During AF the Live View is darkened and frozen and returns when the camera has achieved a focus lock or has given up trying, this can take between 0.7 seconds (good light easy subject) and 4.0 seconds (to give up when it can't lock). Note that the screenshots below are taken from the E-410.
This example animation is in 'real time', it took approximately 1.6 seconds for the camera to drop the mirror, focus lock and raise it again before returning the live view with the steady green focus indicator.
The sequence you're seeing here is: live view before focus, half-press shutter release, screen darkens and freezes (mirror down, AF), focus complete (mirror up), live view returns.
Live View: Exposure sequence
In Live View mode the shutter release sequence is; mirror down, measure exposure, mirror up, shutter release (open / close), mirror down, live view enabled. This clearly means that there is a short period where the screen blacks out (around two seconds).
This sequence: live view before exposure, depress shutter release button, shot taken (screen blank), record review image appears and returns to live view.
Live View: Manual Focus magnification
The E-510 features magnified Live View feature; simply press the INFO button until the magnify loupe appears. You can reposition the loupe anywhere in the scene then press OK to magnify. Select between 7x and 10x view by turning the main dial.

Live View: Low Light performance and 'Boost'
Live View performance in low light is surprisingly good, though in very dim conditions the picture starts to get a little grainy and eventually gets too dark to see. There is a Live View boost option, which amplifies the screen image as light levels drop (and eventually flips to monochrome, as below), but there are a couple of issues you should be aware of when using this option.
Firstly since the Live View boost attempts to keep a constantly bright preview image you can't preview the effect of exposure compensation or manual exposures (without the boost on the screen image fairly accurately reflects the exposure, getting dark if it's under exposed, bright if it's over exposed). This also causes a problem if you use the live histogram; since this is measured from the preview image it no longer reflects the actual metered exposure if you use the boost (basically manual exposures or exposure compensations are not reflected in the live histogram). Use with caution.

Live View: Depth of Field preview
One advantage of Live View is that you can get an exact representation of focus point and depth of field on the LCD screen. In the example below the image on the left is at F5.6, on the right at F22 with the DOF preview button held (this is a custom option).
