In Digital Photography, Exposure is controlled by Aperture, Shutter Speed, and ISO, often referred to as the Exposure Triangle.
While the Exposure Triangle helps remind us that there are three controls for Exposure, it's not very helpful when working out how each of these controls works together. So instead, I like to describe Exposure as a Pie or Pizza, let me explain!
For a typical landscape photography senario, I try and keep the ISO near the base ISO of the camera. More of the light needed to expose a scene correctly comes from either the Aperture or Shutter Speed. I want everything in the scene in focus for many of my landscape images, so I need a larger Depth of Field. To achieve this, I narrow down the Aperture resulting in less light being allowed to pass through to the sensor.
While this approach doesn't directly improve the images you take, the more comfortable you are with controlling Exposure and the operational side of taking a photograph. The less you'll have to think about it when on location and the more headspace you have to focus on being creative.

#Exposure #Photography #Photographytutorial
This has been the best analogy for the controls I have come across in the past 100hrs of watching tutorials on photography.
Thanks so much for that, really appreciate your feedback and support, cheers!
Excellent analogy and explanation. Thanks!
Great analogy! Seems like a more natural way of visualising it. Thanks for the info. 👌
Excellent tutorial, Andrew! Thanks, Mate.
Great explanation! Thanks for taking the time to record it.
No worries Chuck, I appreciate you leaving your comment mate! 👍
Novel way to see the relationships in exposure., fascinating. Thanks for sharing the concept.
Definately one of the best video’s I have ever seen explaining exposure 👍😃
Wow, thanks for that Henrik! 👍
You're a great teacher👏🏾
Hi Andrew, the pie analogy works well, I think it is easier to manage and to solve challenging light or composition situations.
Thanks for putting this up.
Very good. Much more easy to visualise than the triangle.
Thanks for that Fiona, Diagrams make everything easier to understand, cheers 😀
Really like the pie analogy. As a very visual learner it makes much more sense to me than the triangle - thank you.
Thanks for letting me know Corinne, I like things layout in graphical form as well. Makes it much easier to understand, cheers! 😀
Great discussion piece, well done on putting this together and thank you for sharing
This makes more sense to me than the triangle version. I can literally see the pieces of the pie getting smaller or larger based on my change of an element! thanks! PS: First Man Photo gave you a nice shoutout on this video!
Really Enjoyed your Explanation, Thank you so much - Watching Adam gave me the 'heads up' how good this is ..WELL DONE Andrew......
I've popped over here after watching a First Man Photography video (he said to say LOL). It's interesting to see the three presented in this way. Thanks 🙂
Thank you, good way to think of it. (after shooting for 60 years I can learn new tricks.)
I now realize I always translated the triangle into something like this.
Great job in making this explicit
Wonderful approach, Andrew! This has huge advantages over the traditional triangle.
Thanks Emile, glad you found this more intuitive. 😀
Great improvement to visualise the 3 exposure components. In explaining the increase is contribution from the shutter when minimising ISO and aperture you describe the shutter speed needing to be longer. It feels better to me to say that the shutter opening time needs to be longer (or slower).
Thanks Derek, you bring up an interesting point that I struggled with for several months when I first started creating video. I totally agree with you, it's the shutter is open for longer. Speed can't be longer, but it's often referred to as longer. In my early videos I'd sometime say the shutter speed is longer and then interchange "longer" with "increase", but increasing Shutter Speed means the opposite. I should have either made that point or be more clear. Good pick up mate! 👍😀
Thanks for sharing Andrew. Nice to see your video🤩
Awesome analogy 💪🏻
Superb Explanation... and very innovative.
Great alternative representation of the triangle and when you think about it, a pie does make more sense. Thank you for more great content.
Thanks for that Glenn, I really appreciate you feedback mate. My main issue with the triangle concept is how does it help? 🤔 Thanks again! 👍
Hi Andrew, thats one nice alternative concept for the exposure triangle. Well thought of and well explained 👍 thanks for sharing 🍻🍀🤘
Great video for explaining exposure etc.... thanks for sharing.. very interesting and informative... cheers..😀
Excellent analogy. This makes more sense than the triangle but it has one downside, I now want a piece of pie. 😆
I like the pie analogy as it does a better job of showing the interactive relationship. I think it's a misnomer to describe ISO as sensor sensitivity control, as its really a signal amplification control. People can relation to increasing an amplifier and the music gets louder--and more distorted. Same with ISO: the greater the amplification, the greater the noise.
Really excellent Andrew. The exposure triangle has always been a poor analogy for me. Yours makes perfect sense.
Really enjoyed that explanation. Was sent over to your channel by Firstmanphotography.
Love the pie theory. in my mind its how I think about exsposures. but never could find a way to explain it well.. Sharing this with a few friends.
Thanks Tracy, you must be a visual learner like myself. Thanks for sharing it around 😀
I have been taking photos for a loooooong time, and this is the first time I have seen this approach to explaining exposure. I think it would be easier for new folks to understand. Nice job.
Very good metaphor.
Nice! A really fresh idea!
Glad you think so Robert, thanks for you comment mate! 👍
Great video. First Man sent me over
Thankyou for your all your tips and teachings Andrew, we never stop learning out here.
Great video Andrew - love the graphics over the content specific video - nice. I remember the days of slide film and more than one time removing a 64 ISO roll (being careful not to wind the tail in and remember how many shots I'd taken) and replacing it with a 400 ISO roll. The fun of film - I take digital only these days. Saw a quick grab of Horseshoe Falls in the video - I recognised it as I was there yesterday. Just watched that Tassie video again now, and you captured some great images. A tree has fallen down on the right of the falls to the displeasure of a few photographers walking away saying "the shot was ruined". I took another tack as I am always looking for a different shot. Just put it up on Instagram if anyone is interested. Look forward to your next video Andrew.
Very informative!
I really like your slices of pie analogy for understanding the interaction of exposure time, aperture, and ISO, but wince a bit at ISO described as changing the sensitivity of the sensor, which is a fixed property of the sensor, rather than amplification applied as information is read out of the sensor. This distinction might seem to be an irrelevant nit until one turns to explaining a strategy such as taking advantage of ISO invariance. Come to think of it, I’d love to see your talents as and educator applied to that one.
Thanks Michael, you are absolutely right, the readout is amplified, rather than the sensor itself being more sensitive. I was thinking about grappling that aspect this video, but decided to take it out (along with a few other bits) to keep the concept simple. I may well take on your challenge and explore this aspect in a future video. As always, I appreciate the value you add to the discussion mate! 👍😀
Well said. iSO can be much higher before digital noise can become dusturbing. My experience is that with Fuji x series like the XT-3 you can set the ISO to 1600 ISO without real noise issues.
Great video and interesting take on the subject :)
A good alternative model to demonstrate the 3 aspects of exposure Andrew. Im sure it will be of help to those who are trying to grasp the concept or as you said those seeking to make that jump to a manual based workflow
Very clear and logical. I like it a lot!
This is really helpful, thanks Andrew.
Thank u
excellent vid Andrew 👍🏻🍷❤️🇦🇺
Thanks Bruce! 👍🇦🇺
Thanks for the great video Andrew! This is very helpful for me 👍🏼
I find the use of a triangle or pie confusing. I have heard some cinematographers use the idea of a pipeline rather than a triangle. For me, this aligns more with how I think my camera works and allows for inclusion of elements such as [CP,ND,UV] filters (which you show yourself using in your video, but you don't mention as they don't show up in the triangle metaphor). I like to think of it as a series where the light first passes through filters, then aperture, then shutter speed, and finally the sensor applies some iso. I could see using the pie metaphor, but I think you may need a slice for filters. Thanks for posting.
This is an interesting point JP. I see filters are in someways slightly different an in others ways similar to the other controls. Some filters are used to control the light (rather than controlling the exposure). You could argue that's the same thing, but there are differences, like a graduated filter let light on to part of sensor/image. Where the other exposure controls effect the entire image. Some filter reduce the light across the sensor, I see that more similar to waiting for the light to fade in the evening, it more an environmental thing...before it enters the lens. Either way, the pie analogy can be extended with another slice, as you mentioned, to accommodate for filters. I really appreciate you share you thoughts and adding value to this discuss mate, thanks! 👍😀
@@Andrew_marr I really find these videos and the discussion useful. As a total beginner/amateur with all of three months experience under my belt shooting a manual camera, I yearn to make something amazing come out of my camera. I have already experienced several moments when I feel like I need another slice of the pie to achieve what I see online (and this is where your metaphor really shines) for my current lack of any ND or CP filters. Keep up the great work.
Really nice way of teaching the exposure triangle, I definitely find it visually pleasing and logical. Great stuff Andrew.
Big thanks Rauri, glad you enjoyed this one mate!
This is an excellent way to explain exposure, Andrew. Very clever!
Really great explanation of the different aspects of exposure in photography Andrew. Quite helpful indeed mate.
Interesting view Andrew. Thinking of it as a whole rather than three different points is a great way to look at it. More intuitive I think. I wonder what other type of image representations are out there that also help to visualize this concept? You've already trademarked the "pie." Hope all is well.
I like it
Great idea Andrew, and an easy to follow explanation. Having that in a visual phone app would be great for beginners or workshop participants.
Superb video 👍🏼
Thanks a ton 👍🏼
Thank you Andrew - excellent way to look at the exposure triangle, I'm going to the pizza shop.
great explanation for us visual learners Andrew ... more importantly how come I didn't make the cut for the video at Mt Field waterfalls ? :)
So the topping on the pie could be an ND filter. That adds another layer of complexity (cheeky hint from another old teacher).
Great video, but I couldn’t find the link to the diagram?
Hi David, click the link, enter your email address click the button and the download link should appear on the page.
Mmmm pie..... I'm hungry
First Man sent me.
Overexposed is like all the pizza slices won't fit in the pizza pan.
Exactly, and underexposed is when the pizza doesn’t fill the pan.
This is a really good analogy, it even makes more sense than the triangle. I'm sure it will be very useful for dole people.
Thanks for sharing your thoughts Maxence, I'm glad it made sense.
