I share a tour of the Air Line Trail, present a gallery of (mostly) trail photos, and discuss camera equipment, shooting conditions, composition, some basic technical issues, macro work, editing, and advanced techniques.
The document discusses the exposure triangle in photography, which consists of ISO, aperture, and shutter speed. ISO refers to the camera's light sensitivity, with higher ISO numbers allowing for faster shutter speeds but increasing image noise. Aperture refers to the size of the lens opening, with wider apertures allowing for more light but less depth of field. Shutter speed determines how long the camera's shutter is open, with faster speeds freezing motion but requiring more light. The document provides examples of typical ISO, aperture, and shutter speed combinations for different lighting conditions.
This document provides an overview of the basics of digital photography for a Boy Scout merit badge. It covers key photography terms, digital camera technology, understanding camera settings and features, taking photographs, downloading and editing images, and displaying and printing photos. It also discusses important concepts like exposure, aperture, shutter speed, ISO, and how they work together to create a proper exposure. Additional topics include composition techniques, lighting, file types, and practicing with your camera.
The document discusses various camera types and equipment including studio cameras, field cameras, and DSLR cameras. It then covers concepts related to depth of field including aperture, f-stop, focal length and distance. Additional topics covered include the rule of thirds composition technique, different vector types, and camera terms such as field of view, exposure, resolution, focus, gain, aspect ratio, light sensitivity, white balance, and ND filters.
This document provides an agenda and overview for a camera/sound bootcamp covering topics such as insurance, how the human eye and camera lenses work, exposure, focus, and depth of field. The bootcamp aims to explain the differences between eyes and cameras, clarify sensor types, and identify factors that affect exposure and depth of field. Key points include how aperture, shutter speed, and ISO impact exposure, as well as how aperture, distance, and focal length determine depth of field.
The document discusses various photography techniques and terms including shallow and deep depth of field, fast and slow shutter speeds, film grain, and digital noise. Shallow depth of field focuses on a subject while blurring the background, while deep depth of field keeps more of the scene in focus. Fast shutter speeds freeze motion but provide less detail, while slow shutter speeds can capture motion but with blur. Film grain and digital noise refer to the texture and speckles that can degrade image quality in film and digital photos respectively.
Sound waves are produced by vibrating objects and their characteristics include pitch, which can be manipulated through illusions like Shepard tones, and speed which varies by medium and can exceed the speed of sound producing a sonic boom. The intensity of sound decreases with the inverse square of distance from the source and is perceived logarithmically in decibels with higher decibel levels associated with louder sounds.
This document summarizes key aspects of cameras discussed in a Digital Visual Effects class. It covers the history of cameras from pinhole cameras to modern digital cameras. It discusses components like lenses, apertures, sensors, and image processing techniques like white balancing, demosaicking, and high dynamic range imaging. The class schedule and assignments are also outlined.
Video technology originated with cathode ray tube television systems but has since expanded. Standards for TVs and computer monitors evolved independently but advances in digital technology are converging them.
The basic principles of image reproduction through still and motion cameras are similar - light is focused onto a photosensitive material to record images that are then developed and printed or projected. In video cameras, light is converted to electrical signals that are scanned and recorded onto magnetic tape then reconverted to images for viewing.
Common video recording standards include NTSC, PAL and SECAM which differ in aspects like lines of resolution and frame rates. Film and video outputs take narrative, experimental, animated and documentary forms and have expanded to include music videos, commercials

A computational camera attempts to digitally capture the essence of visual information by exploiting the synergistic combination of task-specific optics, illumination, sensors and processing. We will discuss and play with thermal cameras, multi-spectral cameras, high-speed, and 3D range-sensing cameras and camera arrays. We will learn about opportunities in scientific and medical imaging, mobile-phone based photography, camera for HCI and sensors mimicking animal eyes.
We will learn about the complete camera pipeline. In several hands-on projects we will build several physical imaging prototypes and understand how each stage of the imaging process can be manipulated.
We will learn about modern methods for capturing and sharing visual information. If novel cameras can be designed to sample light in radically new ways, then rich and useful forms of visual information may be recorded -- beyond those present in traditional protographs. Furthermore, if computational process can be made aware of these novel imaging models, them the scene can be analyzed in higher dimensions and novel aesthetic renderings of the visual information can be synthesized.
In this couse we will study this emerging multi-disciplinary field -- one which is at the intersection of signal processing, applied optics, computer graphics and vision, electronics, art, and online sharing through social networks. We will examine whether such innovative camera-like sensors can overcome the tough problems in scene understanding and generate insightful awareness. In addition, we will develop new algorithms to exploit unusual optics, programmable wavelength control, and femto-second accurate photon counting to decompose the sensed values into perceptually critical elements.
Ramesh Raskar is an associate professor at the MIT Media Lab who researches computational photography. Some of his work includes using varying exposures in video to preserve high frequencies and combat motion blur. He has also developed techniques like image destabilization that use lens and sensor motion to programmably control defocus blur. Raskar aims to advance computational photography to enable high-level scene understanding through techniques like capturing depth from arrays of virtual cameras in LCD screens.
Michael Clawson is a creative railroad photographer. He takes photos from trains as they climb mountains and come back down into towns, finding inspiration in the sounds of the train whistle. Kodak's Steve Sasson invented the first digital camera prototype in 1975 using a 100 x 100 pixel sensor. Planning is important for train photography, considering factors like time of day, schedules, and lighting. DSLR and mobile cameras both have advantages, and using both allows enjoying benefits of both worlds.

This document summarizes Ramesh Raskar's work on coded computational photography. It describes using coded exposure to enable motion deblurring from a single photo in 2006. It also describes using a coded aperture to enable full resolution digital refocusing from a single photo in 2007 and using it for glare reduction in 2008. Additionally, it discusses using optical heterodyning to capture a 4D light field from a 2D sensor and single photo in 2007, as well as coding illumination and spectrum for applications like motion capture and acquiring an agile wavelength profile. The document outlines a progression from epsilon to coded to essence photography.
The document discusses various concepts related to capturing digital media, including:
1) Digital sampling breaks sounds and images into discrete data points that can be stored and reconstructed, with higher sampling rates providing more detail.
2) Video is created by lenses focusing light through an aperture onto a CCD sensor, which converts the light information into digital signals for color and brightness.
3) Color is represented digitally through combinations of red, green, and blue values, while print uses cyan, magenta, yellow, and black inks.
4) Microphones convert sound wave vibrations into electrical signals using transducers, and can have different pickup patterns and connection types.

1. Getting the image right during shooting is important, including composition, use of a polarizer, and properly exposing for highlights.
2. Shooting in RAW format allows more flexibility during post-processing.
3. Minor adjustments during post-processing like levels, exposure, and sharpening can improve the image without making it look manipulated. Practice and experimentation is important.
Mass communication involves specialized groups using technological devices like press, radio, and TV to disseminate content to a large, heterogeneous audience. There are two major components of production - editorial aspects like script-keeping that consider ideology, and technological aspects that use techniques to make communication effective. Television production involves basic systems that convert images and sounds to electrical signals, and expanded studio systems that allow selection, recording, playback, and integration of additional video and audio sources using more complex procedures.
Computed radiography uses a photostimulable plate instead of film that is scanned with a laser to produce a digital radiographic image. The plate contains a phosphor layer that stores radiation energy and emits light when stimulated by the laser, which is then detected and the image digitized. Digital radiography uses a solid-state detector like amorphous selenium that directly converts x-rays to a digital signal in real-time. Both computed radiography and digital radiography allow images to be viewed digitally and integrated into a picture archiving and communication system (PACS) using the DICOM standard.

Key factors in image quality include spatial and contrast resolution. CT has advanced from single detector to multi-detector systems, allowing faster scanning over larger areas.
The document discusses various topics related to photography including the growth of images uploaded daily, reasons for learning photography, types of photography genres, necessary equipment, fundamentals of exposure and composition, extremes in different photography techniques, and the importance of learning to truly see.
Though revolutionary in many ways, digital photography is essentially electronically implemented film photography. By contrast, computational photography exploits plentiful low-cost computing and memory, new kinds of digitally enabled sensors, optics, probes, smart lighting, and communication to capture information far beyond just a simple set of pixels. It promises a richer, even a multilayered, visual experience that may include depth, fused photo-video representations, or multispectral imagery. Professor Raskar will discuss and demonstrate advances he is working on in the areas of generalized optics, sensors, illumination methods, processing, and display, and describe how computational photography will enable us to create images that break from traditional constraints to retain more fully our fondest and most important memories, to keep personalized records of our lives, and to extend both the archival and the artistic possibilities of photography.
The document discusses the history and evolution of radiography technology from analog film-based systems to current digital systems. It provides details on the key steps in computed radiography (CR) where imaging plates capture x-ray data which is then digitally processed to create images. CR involves separate image capture and readout processes. The document also describes direct digital radiography (DR) systems which integrate image capture and readout using flat panel detectors, thereby providing a cassette-less workflow. Overall, the document provides an overview of modern digital radiography techniques and their advantages over conventional film-based systems.
Video technology was first developed for cathode ray tube television systems. As technology advanced, new display technologies emerged such as LCD, plasma, and OLED displays. The basic principles of image reproduction in film and video have their roots in still photography, where light sensitive materials capture images. Film formats have evolved from larger and more expensive professional formats like 70mm to smaller consumer formats like 8mm and digital formats. Video cameras convert light into electrical signals to create and transmit moving images through scanning processes. Standards like NTSC, PAL, and SECAM were developed for color television broadcasts.

Volleyball, born in 1895 through the inventive mind of William G. Morgan, originated as "Mintonette" within YMCA circles in Holyoke, Massachusetts, USA. Quickly evolving from its humble beginnings, it underwent a significant name change to "volleyball" as Alfred Halstead aptly captured its essence during an early exhibition. With standardized rules established, the sport spread rapidly, finding fertile ground within YMCA organizations and beyond. The formation of the Fédération Internationale de Volleyball (FIVB) in 1947 marked a pivotal moment, ushering in a new era of international recognition and growth. Volleyball made its Olympic debut in 1964, captivating audiences worldwide with its fast-paced action and competitive spirit. Over the years, beach volleyball emerged as a popular variant, further diversifying the sport's appeal. Today, volleyball stands as a global phenomenon, celebrated for its athleticism, teamwork, and universal accessibility, embodying the enduring spirit of camaraderie and competition.

2. Eastern Connecticut photographer Stan
Malcolm focuses on the natural world. He finds
the extraordinary in objects and places we often
overlook. An entomologist by training, Stan's
photos have earned many juried awards and
been published in newspapers, textbooks, and
scientific publications.
5. The Air Line was once a railroad renowned for its relatively
straight course from Boston to New York - "as if by a line
drawn through the air." You can still find lumps of coal left
over from the steam era. Today the rail bed has been
converted to a Connecticut linear park and hiking trail.
