The exposure triangle is practically gospel that just about every new photographer needs to master, but there is more to it than simply varying shutter speed, aperture, and ISO to create a balanced exposure. This helpful video tutorial features an experienced landscape photographer discussing how to properly approach the exposure triangle to ensure you can make photos that are both technically and creatively satisfying.
Coming to you from Christian Irmler - Landscape Photography, this great video tutorial discusses the idea of turning the exposure triangle into a “triangle of styles.” The idea is to uncouple style and exposure so your creative vision is not inadvertently cast aside by the goal of getting a technically correct exposure. Creative vision should dictate the technical exposure, as there are many different ways to represent the same scene, and each of those will require a different combination of shutter speed, aperture, and ISO and often, different total exposures. Learning to approach the process in this manner will help you gain far more creative control over images. Check out the video above for the full rundown from Irmler.

Technically, it is not an "exposure triangle" because only shutter speed and aperture actually affect how much light the medium is exposed to. ISO is a matter of sensitivity, not exposure. Just wanted to clear this up in case there are those who haven't hear the term corrected yet. And yes, precise semantics really are of the utmost importance whenever photography is discussed.
Dont be fooled by people trying to tell you otherwise. In the film days, ASA ( American Standards Association) was used to....DISCERN THE SPEED IN WHICH FILM RESPONDS TO LIGHT. When digital popped in, ISO replaced the nomenclature of ASA, but it dod NOT replace its meaning. It, indeed DOES mean exactly what you say it does. Have no idea why some people think otherwise. Thank you sir.
Fair enough but if precise semantics are your objective then your comment linking ISO with sensitivity needs to be corrected. That specific relationship has been debunked on this platform by multiple experts in the past year or so and I believe the collective wisdom these days is that increasing ISO amplifies gain, it does not increase or decrease sensitivity.
