One Way to Get Spot-One Exposure for Your Shots

The shot taken with  spotmeter exposure and +3 EV in-camera correction, opened and adjusted in FastRawViewer

Every day one can see threads on photographic forums where members discuss the various different modes of automatic exposure, trying to find the perfect one. As a rule, these discussions result in the same question – what compensation to automatic metering ought one set to get consistently good exposure? It turns out that no autoexposure mode universally guarantees good out-of-box results.

We are planning to demonstrate that one of the ways of getting good exposure is metering while using the in-camera spotmeter on the lightest part of the scene that needs to maintain full detail (white clouds, snow, etc.) and applying the appropriate compensation to the exposure recommended by the spotmeter.

Can you Evaluate Exposure Using the In-camera Histogram?

They say that "a histogram is a graphical representation of the pixels exposed in your image" or "when judging exposure, the primary areas of the histogram to be concerned with are the right and left edges".

We are going to demonstrate the following:

  • In-camera histograms don't really allow one to analyze the shadows and highlights zones of an image.
  • An in-camera histogram changes significantly with changes in the camera settings such as contrast, picture style, brightness, etc.

So, no. By no means can the in-camera histogram be used by a RAW shooter to evaluate exposure.
