Step 4: How to Use ML
I would recommend using Zebras, Audio Meters (For Video) and Auto Restart (Also Video (this is on the 60D as it can only record for 10-15 mins at a time before stopping, other camera may have this problem but I'm not sure) Other great features include: Motion Trigger, Audio Trigger, and Bulb Timer. The bulb timer mode requires you to use the audio trigger to activate the shot.
Now that you know how to use it, go have some fun! Try the bulb timer on a starry night :)
