# Intervalometer
The intervalometer can be used to take automated picture series at a regular time interval. One of the uses of the intervalometer is to create timelapses, but it has other users as well.
# Configuration
To configure the intervalometer, tap on the configuration button:
The intervalometer can operate in different shooting modes. You can select which one you want to use by tapping on the button and choosing one of the following:
- Interval + total shots. In this mode, the interval (in seconds between photos) and the total number of photos can be set. As reference, the finalization time will be shown, as well as the playback time in case the photos are compiled into a clip.
- Interval + shooting duration. In this mode, the interval (in seconds between photos) and the total shooting time (in hours, minutes and seconds) can be set. As reference, the total number of shots required to meet these criteria will be calculated, as well as the playback time in case the photos are compiled into a clip.
- Interval + playback duration. In this mode, the interval (in seconds between photos) and the total playback time if the photos are meant to be compiled into a video clip (in hours, minutes and seconds) can be set. As refence, the total number of shots required to meet these criteria will be calculated, as well as the finalization time.
- Shooting + playback duration. In this mode, the total shooting time (in hours, minutes and seconds) and the total playback time if the photos are meant to be compiled into a video clip (in hours, minutes and seconds) can be set. As reference, the interval (in seconds) and the total number of photos required to meet these criteria will be calculated.
- Shooting duration + total shots. In this mode, the shooting time and the total number of photos can be set. As reference, the interval (in seconds) and the playback time (in hours, minutes and seconds) —if the photos are meant to be compiled into a video clip— can be set.
Note
The frames per second needed to calculate this can be set by pressing the three vertical dots icon, and selecting Define playback frames per second....
Regardless of the shooting mode chosen, there will be two parameters to set. In order to set them, tap on the corresponding button to set the desired value.
After setting the desired configuration, you can see a summary of the chosen settings on the main screen:
# Usage
To start the intervalometer, tap Start now, on the top right corner of the screen. Then, the intervalometer dialog will disappear, and a toolbar will be shown with information about the progress (current shot/total shots) and the expected remaining time based on the specified time interval. Two buttons let you pause/resume the intervalometer, and stop it.
All settings are available when taking photos with the intervalometer. Even more, if exposure bracketing is enabled when starting the intervalometer, all the bracketed exposures will be taken and they will count as one shot for the intervalometer. You can use this feature to create HDR timelapses by grouping bracketed exposures taken during an intervalometer session.
Important
If the time interval between shots is shorter than the time needed to create the shot(s), one or more picture slots will be omitted, effectively lowering the number of pictures finally taken. Take care to properly measure/calculate the time needed to create the shot(s), specifically when exposure bracketing is enabled.
There is the option to refocus before every shot taken as part of the series. You can find that option in the three vertical dots button in the top right corner of the screen (a menu will be displayed). That option is disabled by default, and that is the recommended setting. In order to achieve consistent focus between shots, set the focus before entering the intervalometer to lock it. If for any reason the focus cannot be locked, or refocusing before each shot is required, enable that option.
Note
Settings desired for the picture series, specifically picture focus, must be set prior starting the intervalometer. When the intervalometer starts, the AF is not triggered. However, you can still tap on the viewfinder to manually trigger the AF system while the intervalometer is running. Focus misadjustments can affect the subsequent pictures. To avoid accidental focus changes during intervalometer operation, activate the focus lock (AF-L).
