Characterize the limits of your system response.

Our dynamic range charts are designed to verify what luminance range your camera can perform with adequate contrast and signal-to-noise ratio. When analyzed with the Imatest Color/Tone module, dynamic range chart images can show the limits of your camera’s perception.
