This is a fantastic video essay! I'm also a big fan of the "Production Triangle", so I appreciate that they made a "Exposure Triangle" to help relate ISO with Aperture and Shutter Speed.
Did you learn anything new? Is there anything you'd add? What is your favorite low-light camera to work with? What low-light camera have you not yet played with but it's on your bucket list?

At best this info is really sketchy very very basic stuff. In the video there is a suggestion of capturing light to dark within a scene. This is not ISO, but in fact latitude. Different aspects of exposure. The statement that one sets the iris and then sets the ISO is certainly an inventive method of working, not anything that anyone shooting moving images or a series of shots that will be cut together in a scene would do as the individual shots may not match. Ignoring so many other half-truths, there is no mention of what correct exposure is. Without a concept of what is correct, this video makes no sense, other than having been posted online.
ISO, in this context, has nothing to do with Greek words, it is the second competing statement in the video that it is the initials of the International Standards Organization, just as the ASA version that is interchangeably used in some places is the American Standards Association. to go into an explanation of something and present two entirely different versions when only one is correct is just a waste of time
This video is a fine example of “internet wisdom”.
I see what you're saying, Andrew Sobkovich. Is there a YouTube video you would recommend? Or a video series? I'm quite fond of Anthony Q. Artis who does a few series on Lynda.com, but I use his videos on lighting, not camera techniques (or in this case, the camera's interpretation of light).
Definitely drop a few links if you've got 'em!
Kay, sorry but I have no links as I rarely watch such videos. I commented upon the above video because an acquaintance specifically asked me about it and what I watched was woefully lacking in what it was trying to explain. Just because someone posts a video on a subject, says nothing about the content or veracity of said video. Watch the videos all you wish, but reach out to people who actually know before acting on the content. The positive intent in posting a video does not mean the poster fully understands the content. They had the necessary skills to be able to post a video but that doesn’t mean they fully understand the subject.
I met my acquaintance for coffee and soon had them pointed in the right direction about exposure and ISO rating as part of the question of what is correct exposure.
