An intervalometer is a device which counts intervals of time. (Other names include interval meter and interval timer). Such devices commonly are used to signal, in accurate time intervals, the operation of some other device. For instance, an intervalometer might activate something every 30 seconds.

With Magic Lantern, there is no need for an external device, we have an intervalometer built right in.

You will find it in the Shoot menu.

The Options

Take a pic every:
  • This is the core intervalometer function.  Here you set the interval between pictures.
  • Note:  The green text at the very bottom of the display shows how long the sequence will take to shoot, based on the Canon report of how many shots are left on the card, or based on the Stop after setting.  It also shows how long the timelapse will display for at 24fps.

Start trigger:
  • Leave Menu:  Start the intervalometer after leaving the Magic Lantern menu.
  • Half Shutter:  Start the intervalometer after half pressing the shutter button.
  • Take a Pic:  Start the intervalometer after taking a picture.

Start after:
  • Set a delay between the trigger action, and the actual starting of the intervalometer.

Stop after:
  • How many pictures to take.

Manual FocusRamp:
  • Ramp the focus in steps per shot.

  • You can stop the intervalometer by rotating the mode dial, by pressing MENU or PLAY, or by turning off the camera.
  • The intervalometer times from itself.  In other words, as soon as it triggers, the timer counts down from that trigger event.  If you have some other processing being enabled, say AETTR, you need to make allowances for this processing, combined with your slowest shutter speed, to ensure the previous processing has been completed, before the intervalometer reaches the next trigger event.
  • To avoid flicker, shoot in manual mode, use manual white balance, avoid short exposure times and use a manual lens (if you use an EF lens, lock the aperture and unscrew it).
  • Adjust your auto-off setting to longer than your timelapse interval the camera will turn off before the second shot.

Power Saving:
  • When not in LiveView, press DISP or INFO to turn the display off.
  • In LiveView, ML will turn the display and the sensor off during idle times if you enable this option from Powersave menu.
  • While the intervalometer is running, the card led will blink once per second to let you know it's alive and kicking.

AETTR discussion moved here:

This will do ramping.

I'm looking to shoot a multi-day time-lapse and only record during the daytime (for plant growth).  Any chance ML will ad a start/end time or even just a go for X hours then pause for X hours cycle duration?

As written before: I cannot recommend to rely on ML (or any software at all) for long term use. Think about some device using a watchdog timer taking care things running as planned. ML may or maybe not take part in this operation.
