I enjoyed reading this book on cinematography, which was largely accessible to someone with no formal training in film/video production.
Chapters 1-5 in particular were a nice overview of the purpose and artistry of cinematography which talk at a theoretical level about what cinematographers do, with numerous still image examples from real world movies, covering: Storytelling, framing, the illusion of depth, and basic building blocks of filmmaking like continuity and shot types.
Chapters 6-11 provide, what it appears to me to be a survey level of a variety of technical topics: Cameras, the physics of digital recordings, digital encoding techniques, common tools for quantifying the elements of a frame (histograms, waveforms, vectorscope views), and a light introduction to color theory and how it interacts especially with digital camera sensors, file formats, and displays.
Chapters 12-14 are concerned with lighting
Chapters 15-21 cover a variety of topics such as: Grips and grip equipment, camera movement, optics and focus, set operations, digital imaging, power and distribution, and miscellaneous topics.
As a practical guide to cinematography, I suspect the content is too light - being more an overview of the topics and (largely) absent practical advice.
A lot of topics are covered with a mix of some high level theory, and then some expressions of the desired effect, but without sufficient detail to instruct someone how to bring about the effect. I think the Optics and Focus chapter is likely the worst example of this, which begins talking like a physics textbook speaking about refraction indices and describing how photon paths bend in different mediums, before switching altitude abruptly to a laundry list of optical and focus concerns, and largely devoid of any descriptions of technique or methods.
For a textbook it notably is lacking any exercises and has few in-depth examples.
The book also needs a lot of editing - there are numerous errors - most of which do not detract much from comprehensibility, but the volume makes you question in some cases whether they are just goofs or if the author actually knows what they are talking about. Examples include: several figures whose descriptions do not match the visual image they are describing, referring to camera tape as a "paper tape" (camera tape is a cloth tape, paper tape is also pervasively used in filmmaking), and a table listing what framerates would be safe to shoot when lights are driven by various frequency AC power sources that mislabels an axis with FPS instead of Hz.
I can highly recommend the first 5 chapters of this book for someone who is curious about what cinematography is, and broadly how it is conceived.
