Exposure is fundamental to the process of creating a good quality image. The reason for this is quite simple, as I’m sure many digital SLR camera users are aware. If you underexpose the image you lose shadow detail and raise noise levels, and on the other hand, if you overexpose the image you burn out the highlights. This makes exposure a delicate balancing act. The reward, if you can master exposure, is that you’ve mastered one of the building blocks of photographic technique and one of the keys to creating images of high quality.
One of the things that separates professional photographers from hobbyists is that exposure holds no fear for the pros. They’re aware of the limitations of their equipment, how to work within those limitations and how to cope with whatever lighting situations they are faced with. And, to be honest, there’s no reason why you can’t too. It’s not that difficult, once you understand the basic principles of exposure and how the CMOS sensor in your EOS digital SLR reacts to light.
That’s where Understanding Exposure, my latest eBook comes in. I’ve written this one specifically for Canon EOS digital SLR users, and that has let me go deep and explain in detail how the exposure related tools on EOS cameras work.
Understanding Exposure goes back to basics and explains the principles behind good exposure plus some advanced techniques that will help you calculate the optimum exposure for just about any scene. If you’ve ever wondered exactly what your camera’s histogram is telling you, or what exposing to the right is, or what the relationship between exposure and noise are, the answers are here. By the time you’ve finished reading this eBook you’ll understand how your camera’s exposure sensor works, why you often need to override your camera’s suggested exposure settings and how to do it.
Note: Understanding Exposure is written specifically for the owners of Canon EOS digital SLRS.
