On a camera, what is the long piece that lets you zoom in a lot?

For my birthday I want to buy a digital camera but I don’t know what the long zoom piece is. It is like a big cylinder that you turn to zoom in more. Can someone please tell me! Thanks!

That’s a zoom lens.
You get short zooms and, if you want to zoom in on distant objects, long zooms.
On the little point and shoots it’s done by pressing buttons and the ones where you twist the lens are found on SLRs (that use film) and DSLRs (that save to a card and can be easily uploaded on to the internet).

Projecting a Camera $25.95 In Projecting a Camera, film theorist Edward Branigan offers a groundbreaking approach to understanding film theory. Why, for example, does a camera move? What does a camera “know”? (And when does it know it?) What is the camera’s relation to the subject during long static shots? What happens when the screen is blank? Through a wide-ranging engagement with Wittgenstein and theorists of film, he offers one of the most fully developed understandings of the ways in which the camera operates in film. With its thorough grounding in the philosophy of spectatorship and narrative, Projecting a Camera takes the study of film to a new level. With the care and precision that he brought to Narrative Comprehension and Film, Edward Branigan maps the ways in which we must understand the role of the camera, the meaning of the frame, the role of the spectator, and other key components of film-viewing. By analyzing how we think, discuss, and marvel about the films we see, Projecting a Camera, offers insights rich in implications for our understanding of film and film studies.

Camera Networks $40 As networks of video cameras are installed in many applications like security and surveillance, environmental monitoring, disaster response, and assisted living facilities, among others, image understanding in camera networks is becoming an important area of research and technology development. There are many challenges that need to be addressed in the process. Some of them are listed below: – Traditional computer vision challenges in tracking and recognition, robustness to pose, illumination, occlusion, clutter, recognition of objects, and activities; – Aggregating local information for wide area scene understanding, like obtaining stable, long-term tracks of objects; – Positioning of the cameras and dynamic control of pan-tilt-zoom (PTZ) cameras for optimal sensing; – Distributed processing and scene analysis algorithms; – Resource constraints imposed by different applications like security and surveillance, environmental monitoring, disaster response, assisted living facilities, etc. In this book, we focus on the basic research problems in camera networks, review the current state-of-the-art and present a detailed description of some of the recently developed methodologies.The major underlying theme in all the work presented is to take a network-centric view whereby the overall decisions are made at the network level. This is sometimes achieved by accumulating all the data at a central server, while at other times by exchanging decisions made by individual cameras based on their locally sensed data. Chapter One starts with an overview of the problems in camera networks and the major research directions. Some of the currently available experimental testbeds are also discussed here. One of the fundamental tasks in the analysis of dynamic scenes is to track objects. Since camera networks cover a large area, the systems need to be able to track over such wide areas where there could be both overlapping and non-overlapping fields of view of the cameras, as addressed in Chapter Two: Distributed processing is another challenge in camera networks and recent methods have shown how to do tracking, pose estimation and calibration in a distributed environment. Consensus algorithms that enable these tasks are described in Chapter Three.Chapter Four summarizes a few approaches on object and activity recognition in both distributed and centralized camera network environments. All these methods have focused primarily on the analysis side given that images are being obtained by the cameras. Efficient utilization of such networks often calls for active sensing, whereby the acquisition and analysis phases are closely linked. We discuss this issue in detail in Chapter Five and show how collaborative and opportunistic sensing in a camera network can be achieved. Finally, Chapter Six concludes the book by highlighting the major directions for future research.
