The Power Of Lenses

The Language of the Lens explores the expressive power of the camera lens and the storytelling contributions that this critical tool can make to a film project. This book offers a unique approach to learning how lenses can produce aesthetically and narratively compelling images in movies, through a close examination of the various ways lens techniques control the look of space, movement, focus, flares, distortion, and the "optical personality" of your story’s visual landscape. Loaded with vivid examples from commercial, independent, and world cinema, The Language of the Lens presents dozens of insightful case studies examining their conceptual, narrative, and technical approaches to reveal how master filmmakers have harnessed the power of lenses to express the entire range of emotions, themes, tone, atmosphere, subtexts, moods, and abstract concepts. The Language of the Lens provides filmmakers, at any level or experience, with a wealth of knowledge to unleash the full expressive power of any lens at their disposal, whether they are shooting with state-of-the-art cinema lenses or a smartphone, and everything in between.

Project Report from the year 2011 in the subject Physics - Optics, grade: 1.0, Lancing College, language: English, abstract: This practical report outlines procedures for measuring the power of convex lenses and improvements to standard methods. I have been given a box of 54 lenses with different powers, marked with different colours. My aim was to verify these given values, to find an improvement of my measurements and then to use this method to find the power of the lenses with unknown powers in the box and assemble them to the colour groups. The power has been calculated from measured values of u (distance from object to lens) and v (distance from focussed image to lens) by using the lens equation.

This classic series by Dr. Kraskin, originally published by OEP in 2 volumes from 1981 to 1983, has been revised and reformatted into a single volume. The behavioral concept of vision recognizes that the critical element involved in the control and altering of behavior is a lens, wrote Kraskin in the original Introduction to Lens Power in Action. Lenses are the basic tool for the optometrist who practices behavioral vision care. Kraskin gives the reader a thorough overview of how optometrists uselenses to treat and prevent vision problems.

Designed to be used as a quick reference, this fourth edition of the Clinical Manual of Contact Lenses allows readers to easily find the topic and information they need without having to search through an entire chapter to find it. Rigid gas permeable lens design and fitting, soft lens problem-solving, astigmatic management, and bifocal correction are just a few of the subjects covered in this manual. Each chapter includes sample cases to reinforce and demonstrate the practical nature of the topic, with nomograms and proficiency checklists summarizing and emphasizing the important points. With this guide, students and practitioners will have a dependable resource to help fit, evaluate, and troubleshoot any contact lenses, especially specialty designs for years to come.

The Basic Bookshelf for Eyecare Professionals is a series that provides fundamental and advanced material with a clinical approach to clinicians and students. A special effort was made to include information needed for the certification exams in ophthalmic and optometric assisting, low vision, surgical assisting, opticianry, and contact lens examiners. This book was written by a licensed dispensing optician for the express purpose of teaching optometric and ophthalmic assistants everything they need to know about frames and lenses. Ophthalmic frames are discussed in great detail, including basic principles, materials, special adaptations, and selection. Fitting and dispensing instructions are also included to help you satisfy your patients and customers.

Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology and optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with "hands-on" experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensable resource.

This is the only book that combines conceptual and practical instruction on creating polished and eloquent images for film and video with the technical know-how to achieve them. Loaded with hundreds of full-color examples, The Filmmaker's Eye is a focused, easy-to-reference guide that shows you how to become a strong visual storyteller through smart, effective choices for your shots. This book has struck a chord worldwide and is being translated into several languages After a short introduction to basic principles, a variety of shots are deconstructed in the following format: - Why It Works: an introduction to a particular type of shot - How It Works: callouts point out exactly how the shot works the way it does--the visual rules and technical aspects in action - Technical Considerations: the equipment and techniques needed to get the shot. - Breaking the Rules: examples where the "rules" are brilliant subverted
