What is the difference between PDR and DR?

Clipping point. DR uses the noise floor, IIRC. Bill uses a higher point. The is a difference of opinion within the community regarding which is more useful, and which is more objective.

Also. Please watch this video and let me know your opinion.


My opinion is that he's talking about "usable dynamic range", which is something where he sets an arbitrary clipping point. In this, he's more like Bill Claff than DxOMark, and therefore less like actual dynamic range. Use a different clipping point and you will get a different result.


I call dynamic range based on read noise Engineering Dynamic Range (EDR).

So by "actual dynamic range" you mean EDR.

EDR is not the only dynamic range possible; dynamic range (lower case) is a generic concept.
