kinds of artificial light sources for photography Light‚ is the main ingredient in a photograph. There are of course other ingredients: time‚ composition‚ subject matter‚ emotion and your unique style‚ but light is the thing that makes photography work. Light is the thing that early inventors had to hold or fix‚ in order to make a photograph stick around. We call nature’s light‚ natural or available. Think of sunlight or moonlight. There are four common types of artificial light sources used in photography

Hybrid Electric Vehicles The Dark Side John Orttenburger Lake Superior State University April 10‚ 2011 Abstract In the past decade‚ hybrid electric vehicles (HEV) have been making a big commotion with the innovative‚ gas saving technologies that accompany them. The illusion that HEVs are 100 percent environmentally friendly in all aspects also follows the HEV wave. Sadly the illusion often wins over unsuspecting customers the instant better gas mileage is offered. This review on the environmental

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

The absence of light There is no darkness‚ only the absence of light. You cannot measure the dark; it is a measure of illumination‚ or in some cases‚ a lack of it. This point stands in both a physical and metaphorical state. Imagine a pitch-black room‚ if I were to ask you “what do you see?” would you say “the dark”? How can you see darkness? You can’t. You notice that there is an absence of light. In the same way‚ when we judge someone to be‚ in essence‚ evil‚ that is just how we perceive it

LIGHT PEN A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer’s display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen detects a change of brightness of nearby screen pixels when scanned by cathode ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at

different types and point out the advantages and disadvantages of drum and disc brakes. Before we make a distinction between discs and drums‚ let me explain the basic working principle of any braking system installed in cars. When brakes are applied‚ vehicles come to a halt through application of friction against the wheels. Heat is generated in the process. The conversion of kinetic energy of the rotating wheels into heat slows down the wheel. Early automotive brake systems used a drum design at

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

Purpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method:
