Nikon D40 (color sensor)
- Type
- Sensor
Response
Sensor spectrum; camera filters and windows can change the response.
- red (R)
- green (G)
- blue (B)
Astro mode
Emission-line overlay on the active single-profile plot. Values are the source's own native samples (or a labelled linear interpolation).
