@scottbb I've always been a tower mechanic, really, so I didn't get much of the view. :)

It's a reprint of my "exposure triangle" rant.

>Please repeat with me:
>ISO is not SENSITIVITY
>>Uh, yes, yes it is. That's the definition.
>Sensitivity of a digital camera is determined by its quantum efficiency, ISO is an amplification of the signal.

I really expected him to say about International Standards Organisation.

>The only thing that defines a triangle as a shape is "threeness" (3 sides, 3 angles). It's not intended to be a math problem, it's intended to be an analogy.

Oh I wonder what is the basis for associating exposure triplets with triangles.
>This has to be the most egregious example I've seen of over-thinking and -complicating a really simple, really useful tool for reminding folks that all three of these factors need to be considered in conjunction with one another. In fact, the "threeness" is the whole point.

Yeah, exactly, threeness is the whole point, you nailed it, it is written right there in the article.
@mattdm They are wrong about making it a standalone article, this drives false implications of the readers. Like, "look this user decided to teach us about what we know ourselves with some serious 9th grade maths which we do not remember and made a whole article from it".

They do not have a clue about this is what we are generally doing at SE.
photo.stackexchange.com/questions/80285/… - maybe he could try using full auto if the photo from a smartphone looks that much better than a photo from a magnitudes better camera.

I love how modern technology highlights all strange tastes of people making photos. Imagine that there were no HDR, satration bump, manual white balance and all that garbage which people overuse: how would you know how, ahem, SPECIFIC their approach is?

photo.stackexchange.com/questions/6598 - really amused by the quantity of different triangles present. None of them illustrates the profit of using triangle to explain exposure.
