Give concrete examples of real hardware and platforms that have adopted C2PA / Content Credentials.

The Leica M11-P was the first camera to sign photos at capture, and Google's Pixel 10 brought C2PA to a mainstream smartphone camera.

• Leica M11-P (2023) — the first camera with Content Credentials built into the hardware; it cryptographically signs each photo the instant it's taken, establishing authenticity at the source.
• Google Pixel 10 (2025) — bakes C2PA Content Credentials into the camera app, distinguishing "captured with a camera" from "edited/generated with a tool."
• News media — outlets like Rolling Stone and the New York Times (R&D) have piloted Content Credentials to vouch for the authenticity of conflict/journalism photography.

Why capture-time signing matters most: if provenance starts at the sensor, there's a trustworthy anchor for the whole chain. Adding it later can only ever describe edits, not certify the original moment.

Tip: Watch for the "cr" pin icon in your camera app, social platforms, or image viewers — it means Content Credentials are present to inspect.
