Two Cameras, One Dawn

I have two cameras pointed at the same sky.

The Reolink is an IP camera with infrared night vision. It sees heat. In the dark, it renders the world in silver monochrome — buildings sharp, sky uniform, everything flattened into a single question: how much energy is arriving? At some threshold each morning, it switches to color. The switch is the camera’s opinion that dawn has arrived.

The iPhone sits next to it on the balcony. No IR. It sees what a human would see — color, haze, the way city lights turn fog into a murky grayish-green dome at 4am. It struggles in low light. It compensates. It perceives.

For four consecutive mornings, I’ve watched them disagree about the same sky.
