Quack Summer 2016
Summer 2016 - Vol. 15, Issue 3 All contents © 2016 E.J. Peiker Welcome to the quarterly newsletter from E.J. Peiker, Nature Photographer and www.EJPhoto.com . In this quarterly publication, I share with fellow photographers my photographic experiences, photo equipment reviews, photo and processing tips, and industry news. I also inform subscribers about upcoming workshops and products that I offer. Please feel free to forward this to other photographers and interested parties but please do so only by forwarding this newsletter in its entirety. All content is copyrighted by E.J. Peiker and may not be reproduced. If you would like to be added to the mailing list, unsubscribe, or access back issues, please visit: www.ejphoto.com/newsletter.htm Playa de Gueirua - Asturias, Spain (Sony a7R II, 35mm) Three Kits for Three Types of Photography One of the most common questions that people ask me is what gear I shoot with or for recommendations on what gear to take on different photographic expeditions. While the answer to this is very individual and the right set—up varies from person to person, I can tell you what I have chosen for the time being. Wildlife and Birds: I continue to use the Nikon crop sensor DX bodies for this type of photography coupled with either the Sigma 150-600mm Sport lens, the Nikon 500mm f/4VR lens or the Nikon 80-400 lens. The 500mm lens is often coupled with the latest Nikon 1.4x teleconverter to achieve a focal length of 700mm. When combining this with the 1.5x crop of the D7200 or the new D500 camera, the effective reach is sufficient for almost any subject. -
Radiant Heating with Infrared
W A T L O W RADIANT HEATING WITH INFRARED A TECHNICAL GUIDE TO UNDERSTANDING AND APPLYING INFRARED HEATERS Bleed Contents Topic Page The Advantages of Radiant Heat . 1 The Theory of Radiant Heat Transfer . 2 Problem Solving . 14 Controlling Radiant Heaters . 25 Tips On Oven Design . 29 Watlow RAYMAX® Heater Specifications . 34 The purpose of this technical guide is to assist customers in their oven design process, not to put Watlow in the position of designing (and guaranteeing) radiant ovens. The final responsibility for an oven design must remain with the equipment builder. This technical guide will provide you with an understanding of infrared radiant heating theory and application principles. It also contains examples and formulas used in determining specifications for a radiant heating application. To further understand electric heating principles, thermal system dynamics, infrared temperature sensing, temperature control and power control, the following information is also available from Watlow: • Watlow Product Catalog • Watlow Application Guide • Watlow Infrared Technical Guide to Understanding and Applying Infrared Temperature Sensors • Infrared Technical Letter #5-Emissivity Table • Radiant Technical Letter #11-Energy Uniformity of a Radiant Panel © Watlow Electric Manufacturing Company, 1997 The Advantages of Radiant Heat Electric radiant heat has many benefits over the alternative heating methods of conduction and convection: • Non-Contact Heating Radiant heaters have the ability to heat a product without physically contacting it. This can be advantageous when the product must be heated while in motion or when physical contact would contaminate or mar the product’s surface finish. • Fast Response Low thermal inertia of an infrared radiation heating system eliminates the need for long pre-heat cycles. -
Understanding Infrared Light
TEACHER/PARENT ACTIVITY MANUAL Joint Polar Satellite System Understanding Infrared Light This activity educates students about the electromagnetic spectrum, or different forms of light detected by Earth observing satellites. The Joint Polar Satellite System (JPSS), a collaborative effort between NOAA and NASA, detects various wavelengths of the electromagnetic spectrum including infrared light to measure the temperature of Earth’s surface, oceans, and atmosphere. The data from these measurements provide the nation with accurate weather forecasts, hurricane warnings, wildfire locations, and much more! Provided is a list of materials that can be purchased to complete several learning activities, including simulating infrared light by constructing homemade infrared goggles. Learning Objectives Next Generation Science Standards (Grades 5–8) Performance Disciplinary Description Expectation Core Ideas 4-PS4-1 PS4.A: • Waves, which are regular patterns of motion, can be made in water Waves and Their Wave Properties by disturbing the surface.

Infrared photography offers many unique creative choices you can explore in image making • Excellent monochrome images • Sunlit foliage turns white • Blue skies appear very dark • False color can be applied for dream like scenes • Skin tones are ghostly white • Can be shot in the harsh light in the middle of the day A human eye can see light from 400nm to 700nm on the electromagnetic spectrum. This range is called ‘visible light’. IR photography uses “near infrared light” which is in the range of 700nm-1400nm. These wavelengths are longer than visible light and can’t be seen by humans. How IR filters work There are two types of infrared filters, ones that block IR light while passing visible light and ones that block visible light while passing infrared light. The IR blocking filters are used in stock digital cameras to prevent unwanted IR light from reaching the sensor, which is sensitive to near infrared. In infrared photography we want the opposite, to block most or all visible light and only pass infrared light. Two ways to do IR photography – Stock vs IR-Converted Cameras Stock Camera with Converted Camera with Screw-on external IR filter Internal IR filter • Dim or no preview image • No screw on filter required • No autofocus • Normally bright preview image • Exposure metering can be difficult • Autofocus using live view • High ISOs & long exposures • Exposure metering can be difficult • Requires tripod • Low ISOs • Tripod not always required Camera conversions • Life Pixel https://www.lifepixel.com • Kolari Vision https://kolarivision.com Using Stock Cameras for IR Photography Stock digital cameras have a limited range of sensitivity to infrared light. -
Digital Infrared Photography by Vega Buchbinder
Digital Infrared Photography By Vega Buchbinder The advent of digital cameras has made infrared photography relatively easily accessible. No longer does one need to handle and process infrared film in the dark under stringent conditions. In the days of film photography Kodak’s film HIE High Speed Infrared Film was the première infrared film, noted for its extensive range. Kodak has stopped making this film in 2007. Today, with a digital camera, an infrared filter, and a tripod, anyone can explore the near infrared spectrum photographically with ease and repeatable results. Using digital infrared (IR) photography one can produce fascinating images that can look surreal, or of an alternate reality. In addition one can use many variations in image rendering, ranging from black and white, to false colors, in order to create artistic images. What is infrared photography? What makes digital infrared photography possible is that the silicon sensors used in digital cameras can “see” into the infrared range of the electromagnetic spectrum. From short wavelengths to longer wavelengths, the electromagnetic spectrum is made of gamma rays, X- rays, ultraviolet rays, visible light, infrared rays, radar, FM radio, TV, and AM radio. The human eye is sensitive to wavelengths from approximately 400 to 700 nanometers (nm), which is the wavelength range for visible light. The CCD and CMOS sensors in digital cameras can easily “see” further into the infrared region to about 1050 nm, which makes IR photography with a digital camera possible today. Note that this part of the IR range is called the near infrared. Thermal infrared rays are much longer, and are not detectible by the CCD or CMOS sensors in our digital cameras. -

Live Streaming with Your Nikon Camera
Live Streaming with your Nikon Camera PUBLISHED - 11 JUN 2020 Ultimate Guide to Live Streaming with your Nikon Camera If you want to achieve outstanding image quality when live streaming during a video conference call, follow the steps outlined below to achieve a more professional look to your video image quality and audio. Let’s take a look at the equipment required: Nikon DSLR or Z series camera with Clean HDMI output Nikkor Lens Tripod Capture Card or Device Live Streaming Software Lighting Microphone Computer Optional: EH-5B & EH-5P Power Adaptor and dummy battery Achieving a professional quality broadcast look is not as difficult as you think, and there are many different ways to configure and setup the components to enable you to ‘Go Live’. I will take you through the setup I have in place that meets my requirements, but they are 1 of 11 alternative ways to do this depending on the quality and complexity of the streaming solution you require. Camera Setup Lens Choice The lens you use will be determined by the space you have available and the look you want in your stream. A zoom lens such as a 24-70mm f/2.8 or f/4 will give you flexibility with your composition and framing. You could also consider a 35mm or 50mm f1.8 prime lens, which will both give a really good look to your stream, but are less flexible when it comes to framing your shot. A f/1.8 lens is a good choice if you want to hide a distracting background by setting your aperture to f/1.8. -

Undersea Warfare
THE EMERGING ERA IN UNDERSEA WARFARE BRYAN CLARK www.csbaonline.org 1 The Emerging Era in Undersea Warfare Introduction U.S. defense strategy depends in large part on America’s advantage in undersea warfare. Quiet submarines are one of the U.S. military’s most viable means of gathering intelligence and pro- jecting power in the face of mounting anti-access/area-denial (A2/AD) threats being fielded by a growing number of countries. As a result, undersea warfare is an important, if not essential, element of current and future U.S. operational plans. America’s rivals worry in particular about the access submarines provide for U.S. power-projection operations, which can help offset an enemy’s numerical or geographic advantages.1 Broadly speaking, undersea warfare is the employment of submarines and other undersea sys- tems in military operations within and from the underwater domain. These missions may be both offensive and defensive and include surveillance, insertion of Special Forces, and destroy- ing or neutralizing enemy military forces and undersea infrastructure. America’s superiority in undersea warfare is the product of decades of research and develop- ment (R&D), a sophisticated defense industrial base, operational experience, and high-fidelity training. This superiority, however, is far from assured. U.S. submarines are the world’s qui- etest, but new detection techniques are emerging that do not rely on the noise a submarine makes, and that may render traditional manned submarine operations far riskier in the future. America’s competitors are likely pursuing these technologies while also expanding their own undersea forces. -
