The Exposure Triangle: Something Every New Photographer Should Master

The exposure triangle is probably the most crucial concept every new photographer should learn and master as soon as possible. This excellent video will introduce you to the exposure triangle, how it affects your images, and how to use it to your advantage.

Coming to you from Sareesh Sudhakaran of wolfcrow, this great video will show you how the exposure triangle works and how to use it in practice. The exposure triangle refers to shutter speed, aperture, and ISO and how the combination of the three combine to make a balanced exposure in an image. It is about more than simply getting the exposure right, however. The three exposure parameters allow you to make various creative decisions, often with a tradeoff in other areas, such as sharpness, noise, or motion blur, and deciding how to balance these creative and technical decisions in the moment is one of the most fundamental skills of a professional photographer. Check out the video above for the full rundown from Sudhakaran.

We all know it's not a triangle, right?

Agree with your point, very 20th century. Fstoppers, assuming articles like this are meant to educate, should be editing dated material to reflect proper terminology.

I didn;t know that. Please give a search or link. Is it like the color space, which is somewhat triangular? What other "dimensions" are there in exposure beside iso, aperture, and shutter speed. I suppose reciprocity has some effect, and this is particularly important with high speed flash at one end, or long exposures on the other end, Of course, effects on :slit shutters above sync speed might be a factor, but that is exposure related, but only a side effect.

Not applicable to digital photography IMO...

Huh? Exposure is a combination of shutter speed, aperture and ISO number. Care to enlighten us which of those are not applicable to digital?

ISO is not applicable for digital.

It's too long a topic for a comment, but, try it sometime practically. As long as the light is good enough, you can move the ISO to extremes with no impact on IQ.

I'm new to photography and confused about ISO. So if I change my ISO but I leave my Aperture and Shutter exactly where they are, will I affect the exposure? (Not asking about image quality. Asking about image exposure).

Seems my comment caused some confusion. Stick to the "triangle", but, also keep in mind that depending on your gear, you can change the "exposure" in post to some amount w/o any loss. Also, film was a totally different medium where the physical chemicals and material changed which was ASA (ISO). Your digital sensor remains the same.

In short, stick to the "triangle" and experiment and see...
