NOTES:

Each test performed with all other DV500 settings at default

Analog capture to DPS Perception VR via S-VHS after color-bar calibration

Measured in Photoshop (0 IRE = 0% / 7.5 IRE = 11% / White = 100%)

Kodak Chip chart provided a 4-stop latitude

Illumination - Mole 407, 1K, 320 F.C.

Spot meter - 800ASA & 60/sec  = 11.0 F-stop

DV500 F-stop - 8+2/3

White balance to Kodak White chip

The first graph of each measurement is a linear reading of pixel luminance

The second graph is the first converted to a log2 and normalized to 0-10

No attempt was made to smooth the data.
