1.1 Introduction to the Digital Systems
1.1 Introduction to the digital systems PHO 130 F Digital Photography Prof. Lorenzo Guasti How a DSLR work and why we call a camera “reflex” The heart of all digital cameras is of course the digital imaging sensor. It is the component that converts the light coming from the subject you are photographing into an electronic signal, and ultimately into the digital photograph that you can view or print PHO 130 F Digital Photography Prof. Lorenzo Guasti Although they all perform the same task and operate in broadly the same way, there are in fact th- ree different types of sensor in common use today. The first one is the CCD, or Charge Coupled Device. CCDs have been around since the 1960s, and have become very advanced, however they can be slower to operate than other types of sensor. The main alternative to CCD is the CMOS, or Complimentary Metal-Oxide Semiconductor sen- sor. The main proponent of this technology being Canon, which uses it in its EOS range of digital SLR cameras. CMOS sensors have some of the signal processing transistors mounted alongside the sensor cell, so they operate more quickly and can be cheaper to make. A third but less common type of sensor is the revolutionary Foveon X3, which offers a number of advantages over conventional sensors but is so far only found in Sigma’s range of digital SLRs and its forthcoming DP1 compact camera. I’ll explain the X3 sensor after I’ve explained how the other two types work. PHO 130 F Digital Photography Prof. -
Diy Photography & Jr: Photographic Stickers
1 DIY PHOTOGRAPHY & JR: PHOTOGRAPHIC STICKERS For grade levels 3-12 Developed by: PEITER GRIGA The world now contains more photographs than bricks, and they are, astonishingly, all different. - John Szarkowski Are images the spine and rib cage of our society or are we so saturated in photography that we forget the underlying messages we ‘read’ from images? Are we protected/ supported by images or flooded by them? JR’s work elaborates on the idea of how we value images by demonstrating our likenesses and differences. This dichotomy is so great in his work; JR can eliminate himself as the artist, becoming the egoless ‘guide.’ As part of his Inside Out Project he allows people from all around the world to send him pictures they take of themselves, which he then prints out a poster sized image and returns to the image maker, who then selects a location and hangs the work in a public space. In a traditional sense, he hands the artistic power over to the participant and only controls the printing and specs for the images. The CAC participated in the Inside Out Project as early as 2011, but most recently through installations in Fountain Square, Rabbit Hash, KY, Findlay Market, and inside the CAC Lobby. The power of the image and the location of the image are vital aspects of JR’s site-specific work. Building upon these two factors is the material used to place the image in the public space. His materials usually include wheat paste, paper, and a large scale digitally printed image. -

Digital technology has produced Image Sensor (CCD-CMOS) generations of personal computers, which turned all forms of technology into a digital one. Photography received a large share in this development in the making Image Storage (Digital of cameras, sensitive surfaces, image storage, image transfer, and image quality and Memory) clarity.

The final form of digital technology was not reached all of a Bayer Color Filter sudden; this development – in spite of its fast pace – has been subject to many LCD display pillars, all of which have contributed to reaching the modern traditional digital Digital Viewfinder. shape of the camera and granted the photographer capabilities he can use to produce images that fulfill their task. Reaching this end before digital technology was quite difficult and required several procedures to process sensitive film and paper material and many chemical processes. Nowadays, this process is done by pushing a few buttons. This research sheds light on these main foundations for the stages of digital development according to their chronological order, along with presenting scientists or production companies that have their own research laboratories which develop and enhance their products. -

Deep Learning-Based Color Holographic Microscopy

Abstract We report a framework based on a generative adversarial network (GAN) that performs high-fidelity color image reconstruction using a single hologram of a sample that is illuminated simultaneously by light at three different wavelengths. The trained network learns to eliminate missing-phase-related arti- facts, and generates an accurate color transformation for the reconstructed image. Our framework is ex- perimentally demonstrated using lung and prostate tissue sections that are labeled with different histo- logical stains. This framework is envisaged to be applicable to point-of-care histopathology, and pre- sents a significant improvement in the throughput of coherent microscopy systems given that only a sin- gle hologram of the specimen is required for accurate color imaging. 1. INTRODUCTION Histological staining of fixed, thin tissue sections mounted on glass slides is one of the fundamental steps required for the diagnoses of various medical conditions. Histological stains are used to highlight the constituent tissue parts by enhancing the colorimetric contrast of cells and subcellular components for microscopic inspection. -
Digital Photography Basics for Beginners
DIGITAL PHOTOGRAPHY BASICS FOR BEGINNERS by Robert Berdan [email protected] www.canadiannaturephotographer.com These notes are free to use by anyone learning or teaching photography. 1. Choosing a camera - there are 2 main types of compact cameras A) Point and Shoot Camera (some have interchangeable lenses most don't) - you view the scene on a liquid crystal display (LCD) screen, some cameras also offer viewfinders. B) Single Lens Reflex (SLR) - cameras with interchangeable lenses let you see the image through the lens that is attached to the camera. What you see is what you get - this feature is particularly valuable when you want to use different types of lenses. Digital SLR Camera with Interchangeable zoom lens 1 Point and shoot cameras are small, light weight and can be carried in a pocket. These cameras tend to be cheaper then SLR cameras. Many of these cameras offer a built in macro mode allowing extreme close-up pictures. Generally the quality of the images on compact cameras is not as good as that from SLR cameras, but they are capable of taking professional quality images. SLR cameras are bigger and usually more expensive. SLRs can be used with a wide variety of interchangeable lenses such as telephoto lenses and macro lenses. SLR cameras offer excellent image quality, lots of features and accessories (some might argue too many features). SLR cameras also shoot a higher frame rates then compact cameras making them better for action photography. Their disadvantages include: higher cost, larger size and weight. They are called Single Lens Reflex, because you see through the lens attached to the camera, the light is reflected by a mirror through a prism and then the viewfinder.
