If you are using the Capture Pilot app on an iOS device in combination with running Capture One Enterprise, you have the option to display the Guides on top of the image viewed on the iOS app screen. The Guides can be toggled on and off in the Capture Pilot app by tapping on the Guides icon at the bottom of the app screen. It is worth to point out that the visibility in the app is controlled independently of whether the Guides are enabled or not in Capture One Enterprise. This means that the same Guides can be hidden in Capture One Enterprise but visible in the Capture Pilot app, or vice versa.
You will need to update the Capture Pilot app (version 2.2.x or later) to enable the Guides functionality. Also, note that Capture One Enterprise controls the layout of the Guides used. You cannot change the Guides on the connected device, you can only toggle their visibility on and off.
