Olympus Live Time mode

introduction

another long exposure mode pioneered by Olympus in their Micro Four Thirds system
essentially allows one to press the shutter release to start the exposure then WATCH the image build up on the LCD screen, then when you think it has had enough exposure, you simply press the shutter release again
note: Olympus Live Composite mode may be even more useful for you!

in the Menu, set:
- Cogs E. Exp/ISO: BULB/TIME Timer to your maximum desired exposure duration (1-30 minutes)
- Cogs E. Exp/ISO: Live TIME to the live view refresh interval (0.5-60sec)
  - NB. max. number of refresh displays are dependent upon ISO (9 for ISO 1600 to 24 for ISO 100)
  - if you are wanting around 30secs exposure, choose 4 secs refresh interval as this will allow 4-96sec exposure duration with visual updates
set IS to OFF (assuming you are using a tripod)
select Manual exposure mode on the PASM dial
select ISO and aperture
set shutter to Live Time
press the shutter release to start the exposure
watch the screen
press the shutter release to end the exposure
