You probably have a camera with a menu system with 101 modes that you never use, and wonder why they are there. I'm the same. Over the years I've used an endless number of cameras and generally end up setting aperture priority mode, and using exposure compensation to tweak the camera's suggested exposure.
But from time to time a camera appears with something new and an interesting take on an existing feature.
Today I discovered a brilliant new feature on my recently purchased Olympus OM-D camera - LiveBulb mode.
This feature is set in the menu and then activated from the manual exposure mode. Your dial passed the usual manual shutter speeds (60 seconds being the longest on this Olympus) And then you reach the LIVEBULB and LIVETIME modes. These modes refresh the LCD with a live preview as the exposure is being made so you can stop when there's enough light in the shot. It's a fantastic feature for those who use long exposure filters such as the Lee Filter Big Stopper where exposures can stretch into several minutes.
To use the feature you first need to turn it on in the custom menu and select the frame refresh rate. The screen will refresh up to 24 times at ISO200 and 9 times at ISO1600 and you can have refresh intervals of between 0.5sec and 60sec.
So if you think your exposure is going to be about one minute and you're shooting on ISO 400 (19 times refresh) You could set 4sec on the display count and that would mean you would get 15 previews as the exposure builds up to one minute. Press the shutter release and hold it down in LIVEBULB and watch the exposure build, then let go when it looks correctly exposed. In LIVETIME mode the shutter stays open without you having to hold down on the shutter button. A second press closes the shutter.
