Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image. 8. You should be able to change to the next objective lenses with only slight focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place.
Photography had been existing for many years, in which various photographers discovered / invented many types of different movements with their ability of being artistic, one such example is straight photography. Pure photography is another word for straight photography, and refers to photography that attempts to depict a scene or subject in sharp focus and detail, in accordance with the qualities that distinguish photography from other visual media, particularly painting. Pure and straight photography was a style in the 1900's to the 1930's that overlapped Pictorlialsm moving away from the pictorialism style. The pure and straight photography was basically that the photograph should look like a photograph and have the characteristics of a photograph. For example it needs to include, all the visual elements of Depth of Field, details in contrast, and no hand manipulations.
She is also wearing bracelets and a matching ring interconnecting bands in different tones of gold, and onyx and pear shaped diamond drops earrings. The photo was shot using natural lighting from a window or a door. As the light is illuminating one side of the face, and the other wise of the face has some shadows. The image is retouched by using sepia toning, this is when you mix certain chemicals that convert metallic silver in the print to a sulfide compound which is a yellowish color. Composition wise, he is using rule of thirds as the main subject which is the broche is on the point of the top line.
The main part of the FT-IR spectrometer is a Michelson interferometer composed of a beam-splitter and two mirrors: one is fixed- and other is moving which produce the interference pattern. 2.2.4. Transmission electron microscope (TEM) TEM is a technique which operates on the same basic principles as that of a light microscope, but uses electrons instead of light. The lower wavelength of electrons compared to that of light, results in better resolution of the TEM image compared to a light microscope image. TEM uses electromagnetic lenses rather than glass lenses to focus the electrons into a very thin beam.
235 (E size) P&P Photographer George Barnar captured some of the earliest panoramic images ever recorded. According to (The Library of Congress, 2015) “Barnard's panoramas were printed from two or more wet-plate glass negatives that were exposed in a conventional camera. The "wet-plates" had to be coated with an emulsion, sensitized, exposed, and developed in the field while the plates were still wet. After each exposure, the camera was rotated to the next section of the panorama to make a new negative”. In the late nineteenth century, cameras began to be produced specifically for panoramic photography.
It was necessary for the light to fall normally onto the plano-convex lens, this meant that a glass plate needed to be oriented at 45° to the incoming light. This glass plate reflected the light downwards and allowed the image to be viewed through it using the travelling microscope. The travelling microscope was focused onto the upper surface of the optical flat. This was done as the produced interference fringes are localised to one plane. It is possible to focus the microscope on this upper surface by focusing on a piece of dust on the lens.
Portraits through photography has changed throughout history from an indoor studio to the great outdoors. In portrait photography, David Bate considers four major visual conventions that includes the face, pose, clothing, and location to rely ideas about the self that communicates the character, personality, and social standing (Bate 73). Portraits from George Nadar’s Sand and Emmet Gowin’s Ruth and Mae are examples of experimentations through tools and decisions that has lead to represent a social identity and innovation in portrait photography. The portrait, Sand, is George Sand with a focused look, head tilted slightly back looking over to her left shoulder. A strong light exposes her right side of her face, leaving shadows on her other
(Hub, 2017) I wanted to investigate reflections further so I know the different kinds of reflections. The materials that I will be using for this experiment is the light box which will be provided in the science laboratory. I chose to use the light box for this experiment because it’s the materials that are best to use in this experiment. (YouTube, 2017) The five different angles of incidence that will be changed is ( 20°, 30°, 40°, 50°, 60°). The angle of incidence = angle of reflection is called the law of reflection.
Afterwards, I conducted a visual analysis for each of the ten Super Normal types, mainly in their Roman and Regular proportions. Using a four-point framework that was inspired by Robert Slimbach’s4 idea of designing a timeless typeface, the chosen types were deconstructed and reduced to abstract forms to measure their legibility, readability, aesthetics and evolution. Figures and proportions were calculated and collected in this part in order to provide practical references for my latter type design of ‘Normal Sans’. Secondly, in the Design Project, the ‘Normal Sans’ was emphasized to further practice the comprehensions and findings that were developed from the Literature Review and Case Study. The outcome of my project takes the form of a humanist sans-serif typeface entitled ‘Normal Sans’.
Consider some of the ways that it can be manipulated during production are Types of shots, types of angles, lens choice, movement and lighting. There are four basic shot types that are based on the apparent proximity of the subject that is Long shot ,Full Shot ,Medium shot and Close up shot. There are three basic types of angles which refer to the position of the frame with respect to the subject within the frame. High Angle ,Low Angle ,Straight-On Angle are the three basic type of angles. As by lens, the only function of a lens is to focus the light that is either projected or reflected from the surrounding environment onto the focal plane of the film.
