Q005: Why are my colors different in RAW converted files compared to camera JPEGs?

A:The full answer is beyond this FAQ but here your are: 3rd party RAW converters (eg. ACR) provide their own color processing which are independed and different form the in-camera color processing. For better understanding see Q001.


Q006: How much can I overexpose a raw file without any harm for the result?

A: Camera models vary in the tradeoff they make between highlight headroom and shadow noise. Some leave a significant amount of highlight headroom during a normal exposure. This allows significant negative exposure compensation to be applied during raw conversion, but also means normal exposures will contain more shadow noise. Other models leave less headroom during normal exposures. This allows for less negative exposure compensation, but results in lower shadow noise for normal exposures.

We advise to be careful with any overexposusre. But if you know your camera and histogram you can improve the noise in your image by using controlled overexposure.


Q007:How do I interpret a histogram?

A: Read "Watch your Histogram"
