Start from this original circular-window illustration. Hold a locked front view with the same selected outer circular opening centered in the frame. Preserve the rigid wall, opening boundary and quiet scene through the window. Keep movement minimal; a very small ambient light change may occur without moving the camera or changing the circular shape. Do not zoom, reshape the opening, introduce text, transform the wall into an object or cut to another scene. End on a stable readable circle. This is one source shot for a later manually edited hard cut.
