New in this release: • Demo Mode: no camera handy? Tap Try Demo Mode on the Camera Connection screen to explore the app with sample 360° brackets. Capture, Live View, Pictures and sharing all work. It ends when you connect a THETA. • Manual: a guide to every screen, in Settings. • Fixed: brackets more than 1 stop apart are now centered on the Center Shutter Speed. Before, they came out darker than intended. • Shot counter: the Capture button counts the photos as they're taken, with a tap and a flash for each exposure. • View Photos: after a bracket, opens just the photos it took. • Color temperature: each bracket is tinted with its color temperature, orange for warm light and blue for cool, in the list and the editor. • Liquid Glass Capture, Cancel and View Photos buttons that no longer cover the bracket's settings. • New camera status icon on the main screen, and a new app icon. • A standard Close button on every sheet, and a clearer highlight for the selected bracket on iPad and iPhone Duo. • VoiceOver and spelling fixes. • Requires iOS 17 or later.
