Kodak DCS 760 vs Kodak DCS Pro SLRn: read noise comparison
Kodak DCS 760
The Kodak DCS 760 was measured at 8 ISO settings from ISO 80 to ISO 400. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
Kodak DCS Pro SLRn
The Kodak DCS Pro SLRn was measured at 15 ISO settings from ISO 6 to ISO 1600. Values are Bill Claff's (Photons to Photos) direct measurements from raw files.
At base ISO (160) read noise is 3.05 DN, or 33.4 electrons at the sensor. Read noise keeps falling across the measured range, so the camera isn't fully ISO-invariant there. Full well at base ISO is about 44,804 electrons; unity gain is around ISO 1740.
