Have you ever stood at the beginning of a very long room or hallway? If you have, then you probably noticed that everything gradually gets smaller in the distance. This is called linear perspective and it is defined by creating an illusion of depth on a flat surface through a series of lines that converge in a single vanishing point. Many architects use linear perspective in there work to this day, but Filippo Brunelleschi was the one who started it long ago in the design and construction of…

Crane’s description of the bar where Pete works subtly highlights the deceptiveness of this bar’s appearance. The words “imitation leather” depict the fake or misleading qualities of the bar. The “massiveness” of the “shining bar” is another deception of appearance as the “mirrors set in the face of the sideboard” make it look larger than actuality. The mirror also “multiplied” the number of “shimmering glasses” giving the feeling of elegance and high quality. However, the glasses were never…

Richard Misrach is an American contemporary photographer that focused mostly on landscape photography. One of his main goals was to capture the effects of the society on nature. (Artnet) Misrach’s work consists mostly of nature and landscapes. His photo I have selected is of the aftermaths of a forest fire at Yosemite. It is unknown weather the fire was man made or from natural causes but it does make one think of the effects they might be having on this gorgeous earth. Misrach’s Yosemite (Burnt…

II INTRODUCTION The purpose of this lab was to demonstrate and observe the effect a large focal spot and a small focal spot will have on the resolution of the image. Chapter 3 of Practical Radiographic Imaging states that resolution is “the ability to distinguish two adjacent details as being separate and distinct from each other” (Carrol, 2007, p. 48). This definition of resolution helps to explain what will be looking for to retrieve the data for this lab. As stated in Chapter 16 of…

Experiment #6: Polarimetry Resolution of (∓)-Racemate: (∓)-ɑ-Phenylethylamine OBJECTIVE All chiral molecules have a mirror image of themselves. While they have the same physical properties, they interact with other chiral molecules completely different. Since there are many chiral molecules in organics, this can lead to the need to make optically pure products. If the chemist does not, it can lead to many problems including death. In this experiment, the separation of two enantiomers was…

Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

SHAH How to do HDR photography (lions) HDR Photography HDR (High Dynamic Range) photography is a form of image processing that uses a series of images captured at different exposures to produce one, amazing photo. The dynamic range is a term used to infer to the ratio of darkness to the light. The idea is usually to compress the compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital…

2.10.1 Fuzzy Inference System (FIS) Fuzzy set theory explain this technique to enhance an image of handwritten scripts and for an edge detection of wrist X-ray images. In the case of the contrast enhancement process of an image, the Fuzzy set also seen as a collection of membership functions, where each represents how much degree of corresponding grayscale pixels is possible to be “bright”. In other words, a Fuzzy membership value of the image Fuzzy set can be understood as the degree of…

1 Introduction Interferometry is a measurement technique which utilizes the interference of waves in a medium to cre-ate interference patterns [5]. In general, the waves can be light, sound or radio waves. The interference pattern is detected by a photodetector and it provides some useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important…

Lesson Plan Teach 1 Name: Spectra and Stars Standard: Identify and compare characteristics of the electromagnetic spectrum such as wavelength, frequency, use, and hazards and recognize its application to an understanding of planter images and satellite photographs. Objective: The students will be able to – 1. Recognize that white light is made up of a spectrum of many different colors. 2. Explain how different colors of light can be absorbed by colored filters. Engage 1. Remembering- How…
