GB, post "Equivalence" as often as you want - just don't call it "equivalent exposure" - that's a blasphemy.

As I recall, I've already posted this in response to one of your posts:


(It should be noted that the term "equivalent exposure" may result in some confusion. For example, all else equal, f/2 1/400 has the same exposure as f/4 1/100, which are called "equivalent exposures" since they arrive at the same exposure with a different f-ratio and shutter speed. Thus, it is better to say that the photos have the same brightness, rather than equivalent exposures, even in the context of equivalent photos, to avoid confusion).

So saith you... so saith you...
