Content & Presentation
The next chapter deals with the aperture and how you can exploit aperture values for better exposure and compositional advantage. I love the rationale that Bryan provides for selecting various apertures for various shots like the “Who Cares" apertures. He also explains the depth of field considerations that come into play once the aperture values have been altered.
The second part of the exposure triangle is the shutter speed. Though most consider the aperture to be the numero uno exposure controlling factor, the shutter speed can as well be a very critical factor in determining exposure for creative shots. Using techniques like panning, implying motion, and freezing motion makes extensive use of shutter speed which also determines the exposure values of the image. Although Bryan has a separate book on the topic of creative shutter speeds, the chapter in this book serves as a primer for interested audience.
Light, the most significant component of any image is definitely a factor that any photographer should learn to manipulate for creative exposures. Bryan takes the reader through the various types of light and how to identify them. He explains what backlighting can do, how sidelight enhances subjects, etc. There are also inputs on night and low light photography.
The final sections on filters and discussion on Film vs Digital are addons to the fundamentals discussed in the previous chapters. Discussions on using Skylight filters, ND filters, polarizers etc. add to the knowledge gained from reading the section on light.
