What photography app has a black background with a red circle in the middle with a little white arrow thing on it?

The Photography app you're describing is likely the default camera app found on many smartphones, particularly on Android devices. The black background with a red circle is a common design for camera shutter buttons. The little white arrow could indicate additional features or settings within the app. If you meant a specific third-party app, it could be "Camera FV-5" or a similar photography app, but the description fits the native camera interface well.
