Light Meters- Use It or Lose It

[ravncat]

if you know transmissivity of your lens/sensor combination and filter factors (if using filters) Incident light metering can still be very useful and very simple to set up - getting things right the first time instead of tweaking in camera. Light falling on the subject is light falling on the subject (- this is how to make an exposure for the moon. -) Incident can help to have a more ambient exposure than a subject exposure - which may be more desirable in some situations - camera meters generally cannot give incident readings.

- I still carry a light meter, precisely for incident readings - (that and my old luna-pro is analog and meters down to an 8 hour exposure - which is far longer than my camera meter can read.) It`s also interesting not to have to deal with reciprocity failure - with digital exposure being linear.
