TwinPics is a script suite for Capture One that automates variant creation when capturing photos. It consists of two scripts:
TwinPics: Configuration interfaceTwinPicsOnBackground: Background automation handle
- macOS 10.10 (Yosemite) or later
- Capture One
- PrefsStorageLib v1.1.0
- Dialog Toolkit Plus v1.1.3
-
Download the laste realease zip archive here or the applescript files.
-
Place TwinPics in your capture one scripts folder.
-
(optionel) Install required libraries only if you choose to install the raw applescript :
- PrefsStorageLib
- Dialog Toolkit Plus
-
I strongly recommend configuring a keyboard shortcut for TwinPics:
- Open System Preferences and go to Keyboard.
- Select the Shortcuts tab, then click on App Shortcuts in the sidebar.
- Click the + button to add a new shortcut.
- In the Application dropdown, select Capture One.
- In the Menu Title field, type the exact name of the menu command you want to assign a shortcut to (e.g., "TwinPics").
- In the Keyboard Shortcut field, press the key combination you’d like to use.
- Click Add to save the shortcut.
