Flip to the rear glass
The front camera is the studio; the rear cameras are the field kit. One tap flips QCam around, and the lens row puts real glass, ultra-wide to telephoto, under your thumb.
One tap, other side
Tap the flip button and QCam swings to the rear cameras: the big sensors, the sharp glass, the side your b-roll wants. The deck around the preview stays the same, so nothing about the app changes when the camera does.
Pick your lens
Beside the frame chip sits the lens pill: real lens steps, 1× and 2× here, following whatever glass your iPhone's rear kit carries. Tapping between them switches lenses, not stretched pixels, so every step is native quality.
The rear side is the b-roll side: hands, desks, demos. Cut those against your front-camera takes and one phone starts feeling like a two-camera shoot.
One tap, other side
Talk to the front camera, shoot the world with the back ones. Same app, same controls, whole kit.
