This practical guide explains the fundamental laws of geometrical optics and how they shape camera lenses, focusing, and image quality. It shows how light travels, how depth and sharpness are controlled, and why stopping down affects brightness and depth. The book aims to help both amateur and professional photographers understand their instruments and make informed choices in real-world shooting.

Readers will gain clear, hands-on insight into topics like depth of focus, image sharpness on ground glass, and the trade-offs between depth and brightness. The text emphasizes practical applications over theory, with guidance you can apply when selecting lenses, setting exposure, and evaluating image sharpness.

How light rays propagate and form images with modern objectives.
What depth of focus means in practice and how to manage it.
How aperture, focal length, and lens design influence sharpness and brightness.
Practical notes on focusing, stopping down, and evaluating image quality.

Ideal for readers of instructional photography texts and anyone who wants a solid, accessible grounding in optical principles behind everyday photography.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
