Times for shooting in Manual exposure mode: doing panoramas or other multi-shot sequences when you want identical exposures across a sequence. Times when using spot metering or very narrow, highly center-weighted metering patterns, so that the subject can be metered and the PROPER exposure set, and then photography can be done, safe in the knowledge that oddball background or foreground objects will no improperly influence the meter readings. In situations where the camera will be following a moving subject that will pass in front of backgrounds of widely varying lighting, such as at racetracks and stadiums, where the BACKGROUND will often be very dark in the middle of the field/pitch/track due to a covered stadium, but where the background will be quite bright at the ends of the field/pitch/track. This is pretty common at track and field stadiums and American football stadiums at many high schools and smaller colleges, where a grandstand with a covered roof extends from the 20 to 20 yard line, but the end zone areas are open. Same thing at smaller horse tracks and rodeo grounds, country fair arenas,etc,etc. When photographing very light-colored subjects or very dark-colored subjects in front of predominantly opposite-toned backgrounds, using Manual exposure mode is actually quite easy. Using manual mode makes sense when you absolutely MUST HAVE a fairly narrow range of speed and aperture settings in order to stop motion and or to make the exposure: with a 300/2.8 late in the afternoon, as the light drops you might be at 1/640 second, which will be "marginal" for motion-stopping with such a long lens, on many action events. At those times, the only thing you can do is KEEP the shutter speed at 1/640 and start raising the ISO setting on the camera as the light gets worse and worse and worse. Minor league baseball and high school track and field in the months of March and April come to mind...lighting for both is often rather marginal, moving to sucky as the day wears on. There are many other scenarios where a manually-set exposure is preferable to one that the camera's light meter determines.
