Understanding Exposure, by Brian Peterson

I spend a lot of time reading. At times, I come across a book that is really well written, as well as informative and useful.

Bryan Peterson’s book – Understanding Exposure, (3rd Edition) is a testament to this ethos, and is simply genius in its descriptive ability to draw the reader in.

As a photographer of a few years now, I have been to evening classes, and spent a lot of time on photographic forums, picking up bits and pieces here and there, but nowhere have I found a book that so simply breaks down the photographic process as this. Even taking an A-Level didn’t educate me as well!

The author somehow takes the most simple of sentences and continues to draw the reader in. It’s almost as if you’re understanding it as you read it without actually knowing that you get it. It’s like a fine ale (if you’re a beer drinker) or good quality chocolate (if you’re a woman), or the Book Of Answers if you’re a photographer.Understanding Exposure at Amazon

I’ve been sat here a while now, thinking of ways to describe just how useful this book is, but sitting back and looking at realms of (now deleted) text, I wondered how useful that is to you, as a potential buyer.

I thought I knew it all, and to be honest, in my cluttered mind, I did know a fair bit. But this book sets everything into a logical order, and explains it with such childlike simplicity and clarity, that I found myself re-learning everything again, only this time, in the proper order. And to an engineer like myself, I was being told why I was doing it that way. Sometimes, once you grasp the concept of “why”, the rest all falls into place. A bit like the magic of hyperfocal distance…

Photography is all about exposure. The amount of light hitting your sensor/film. That’s it. It’s about obtaining that balance. It’s about how to manage/juggle shutter speed, ISO and Aperture to get the right exposure for you. And the emphasis is always on the last two words there. For You. And that’s another great thing about this book. It isn’t about telling you what to do to make a great photograph. This is about equipping you with basic fundamentals to allow you to make a great photograph. There is a huge difference.

As an example, I always used spot metering to evaluate the exposure in a scene. I didn’t really know why, I just did. I pointed the spot at my subject, took a reading, recomposed, then took the shot. That’s fine in most circumstances, but there are forms of photography where it’s not so clear. A sunset for example, or a long range shot of the moon. Within these pages, the explanation is so clear that it’s obvious where you need to meter from in order to take such a shot.

I read this on holiday. And spent a lot of time shaking my head in wonderment as things were explained to me that I really hadn’t bothered with before. But these things were explained with such simplicity, it was more a wonder of how I managed not to “get it” before.

If you have a few quid in your wallet, spend it on the shopping and order this on your card. No matter what level you’re at (professional photographers excluded!) you’ll find this book brilliant.

The book itself is a big glossy softback with some lovely images inside. It’s also got some bad ones too that illustrate how not to do it. The first few chapters are devoted to absolute basics and defining the “Exposure Triangle” of Aperture, Shutter Speed and ISO. These three ingredients are key to understanding different aspects of an image. Peterson tackles each of these three subjects in depth and explains what happens when you have high or low variations of the three options. By understanding what to expect with an Aperture of (for example) 2.8 or a low shutter speed of 1/20 second, or a high ISO of 1600, you as a photographer can elect to make these changes secure in the knowledge of what the effect will be on the final image.

The last major section of the book talks about light itself. This is an unusual chapter and really opens ones eyes to the way light falls on subjects, and how important it is to be able to recognise this. Different types of day and different types of weather can drastically affect how light falls on a subject. My 52 challenge this year is an exercise in learning about light. The same subjects all year round, but images taken in different lighting conditions and at different times of the day can dramatically effect the outcome. The most important aspect of this book is its ability to break down what might first appear quite complicated and make it seem simple. Even now, it still makes me smile when I read it.

Last of all, there is a section about special techniques. The use of filters, multiple exposures, HDR and flash are all discussed within the premise of the previous content. It’s a nice ending to a book that should be on every amateur photographer’s shelf. Well worth the investment!

Thanks for reading!
