Many people choose photography as a career because photos can amaze, shock, or inform if presented in the right manner. Photography is a good career if you enjoy presenting visually, and commutative. The salary range of a photographer can be from $10,000 to $30,000 a year. There are a number of universities that offer diplomas in photography. Some offer it as a three year integrated course and subsidiary subject. A list of colleges that offer this are: ● Utkal University ● OrissaPune University

The first lens creates the image and the second enlarges the object. Tripod Having a tripod is important in macro photography because it helps keep the camera stable while being so close. This helps prevent the picture turning out blurry or unfocused. 7 steps

They say that there’s a right tool for every job. In the case of spotting scopes, their job is to provide close-up visual access to anything on land while staying a safe distance away. Something of a cross between binoculars and a telescope, spotting scopes have uses from nature photography, bird watching, and even hunting. While a telescope is usually used at night to observe the stars, a spotting scope is meant only to be used during the day. When comparing a spotting scope to a telescope or a

one of the world's greatest inventions. It made people learn about the creatures that are too small for the human eye to see normally. But sometimes, the image given by magnification is unclear. And here is a solution: colored magnifying lens. Colored glasses lens change the way people see, so why not improvise and add that feature to magnifying glasses? (not saying to create prescription magnifying glasses) One of the most basic tools for magnification is the magnifying glass, invented by Alhazen

the best results when using a microscope and using the metric system to convert actual measurements of different activities. The reason why objects appear upside down and backwards is because the light rays from the ocular lense into the objective lens cross. If a scientist wants the object to appear right side up through the lense than the object would have to be placed upside down and backwards on the stage to begin with. When there is too much light coming from the diaphragm, the object can get

Seeing Through the Lens Physics Around Campus Haley Sieverding Physics 102 Spring 2016 To the right is a photograph looking through one of my contact lenses. Since it is hard to depict what I see without them in, this photo goes to show what it looks like through the lens compared to what my camera sees with “perfect vision.” Through the lens you can see a tree clearly in the distance which is normally a blurry green and brown tree like shape through my bare eyes. This photo was

are refracted more than the shorter wavelengths. Aperture A device that controls the amount of light admitted through an opening. In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop. Aspherical Aspherical lenses are lenses with complex curved surfaces, such as where the radius of curvature changes

Background knowledge: The topic of this investigation is to compare and contrast three different optical telescope systems that are used in modern day times. The three main telescope systems that will be focused on in this report will be reflecting, refracting and cassegrain which is a combination of both and how different types of error such as aberration effect the telescopes ability to capture an image and the quality of the image it produces. Reflecting telescopes use mirrors to reflect incoming

Real Field of View) and angular degrees (or Apparent Field of View). Real field of view is the angle of the visible field, seen without moving the lens, measured from the central point of the objective lens. The larger the value is, the wider the view-field available. Apparent field of view is the angle of the magnified field when you look through lens. The larger the apparent field of view is, the wider the field of view you can see even at high magnifications. With the conventional method used
