Shutter Robot
Shutter Robot helps you with shots that require specific timing or multiple shutter invocations.
To configure and use Shutter Robot, tap the 
button in the toolbar in Cascable’s remote control.
Choosing a Module
Shutter Robot provides several different options for working with the shutter. Each one of these is called a module. To pick a module, tap the name of the current module at the top of the Shutter Robot configuration popup and pick a new one from the list. Cascable provides the following modules:
- Self Timer is a simple timer — it will wait a period of time before triggering the shutter.
- Bulb Timer will hold the shutter open for a period of time when your camera is in Bulb mode. This is useful for taking long exposures at night.
- Intervalometer is a repeating timer, useful when producing timelapses.
- Exposure Bracketing will automatically adjust your camera’s exposure settings to take a series of photos at different exposures. This is useful for producing High Dynamic Range (HDR) photographs.
Configuring a Module
Once chosen, a module’s settings will be displayed in the middle section of the Shutter Robot configuration popup, along with an estimate of how many photos the module will produce.
To adjust a setting, tap it to display a new panel for configuring that setting. Once configured, tap the Robot button at the top of the panel.
The available settings are as follows:
Self-Timer
- Duration — Change this setting to adjust the amount of time between tapping the shutter and the photograph being taken.
- Audible Countdown — if enabled, Cascable will audibly count down the last three seconds before the photograph is taken.
Bulb Timer
Note: If you have Mirror Lockup enabled on your camera, Shutter Robot will flip the mirror up and wait three seconds before opening the shutter for Bulb Timer.
-
Shot Duration — Change this setting to adjust the amount of time the shutter is held open.
-
Stop — Change this setting to adjust how long Shutter Robot keeps taking shots for.
-
Time Between Shots — If the Stop setting allows more than one shot, you can adjust this setting to configure how much time is left in between shots. This setting should allow enough time for your camera to process the shot, perform noise reducion (if enabled), and write the shot to its storage.
Intervalometer
- Interval — Change this setting to adjust the amount of time between each photograph.
- Stop — Change this setting to adjust when Shutter Robot stops the Intervalometer. You can set a time period, a fixed number of shots, or have Shutter Robot continue until you stop it manually.
Exposure Bracketing
- Range — Change this setting to adjust the total range of the exposures to be taken. A range of +-1 stop will take exposures between -1 and +1 stop from the current exposure settings.
- Increment — Change this setting to adjust the difference in exposure between each photograph. A finer increment will result in more photographs.
Engaging Shutter Robot
Once Shutter Robot is configured, you must engage it before it’ll take over. To do this, tap the green Engage button at the bottom of the Shutter Robot popup. Once engaged, the Shutter Robot icon in the toolbar will highlight. Once engaged, you can dismiss the popup and compose your shot.
Shutter Robot will jump into action when you tap the shutter button in Cascable. When running, a progress bar on the shutter button will inform you of Shutter Robot’s progress.
If Shutter Robot can’t engage for some reason (for example, perhaps the Intervalometer configuration will produce more photographs than will fit on your memory card), the Engage button will be replaced with a notice that there are one or more problems. Tap on this notice to see a detailed explanation of the problem(s) and help with fixing them.
