xx). A small or shallow depth of field is when the range of focus narrow which may be a few inches to several feet (Ramos, XX). There are three main factors that contribute to the depth of field – aperture size, distance from the lens, and the focal length of the lens (Ramos, XX). The aperture which adjusts the opening of your came... ... middle of paper ... ...cliff with the waves crashing up, should the image portray the power of the surf?

Missing figures PROPERTIES OF LENSES, OPTICAL GLASS Composition Glass is a solid, structureless and amorphous. There are two main group classification of optical glass: 1. Crown, and 2. Flint (has a high content of lead oxide) Chemicals are combined to produce new glass types. These new glass types are used to benefit other different types of cameras (such as high-speed minature cameras, black/white cameras, etc). Properties The most important optical characteristics of a glass
lens and is refracted through the focal point on the opposite side, lastly there is the focal ray, which shines through the focal point that is on the same side of the lens as the object and at the middle of the lens is refracted parallel to the lens. At the point where two or more reflections of the rays meet is where the image is created. A real image is one that is
Photography What is photography and how has it evolved? Photography has been around since 1000 A.D. The first camera was called a Pinhole Camera, invented by Alhazen in the 1500’s. “The exposure time on taking the photo was fifteen to twenty seconds in a sunny scene.” (Hawshaw 1) Photography was and is used to take family portraits and even for studies. Today with the power of digital photography any one can take one picture or one hundred. It’s only a click of a button away with today's cameras
back of the photograph. Emphasis can be placed on a certain subject by obscuring the foreground or background. There are three main features that can affect depth of field. Lens aperture (f-stop), distance from the camera to the subject, and the focal length of the lens (Heart 100). In order to understand depth of field one must first understand how light works. We can view objects because of light rays reflecting off their surfaces. These light rays are reflected in innumerable directions. In order
uphold, easy to use, and is capable of global observing as well as stargazing. One problem with refracting telescopes is that there is a frequency requirement for refraction, so the amount of refraction at each surface of the lens depends on the wave length. So, different wavelengths focus at slightly different points. It causes objects like stars to be surround... ... middle of paper ... ...ope, and use the telescope simulator.

During a movie, many actions go unnoticed by the typical viewer. However, while watching a movie, many terms emerge that can label each dynamic aspect of a movie. Knowing and looking for these names can change a viewers experience into a form of acknowledging and appreciating the cinematic arts. Following terms such as panning, mise en scene, and zoom are some examples of these labels. These are just a few of many terms can be seen throughout one movie. One very powerful component of film is panning
After experiencing a traumatic car crash, Michelle, the protagonist of director Dan Trachtenberg’s film 10 Cloverfield Lane, wakes up in an underground bunker owned by a man named Howard. Howard claims to have saved her from a widespread chemical attack that has contaminated the air, with his bunker being the only place to take refuge for the next couple of years. Yet as the film progresses, Howard’s controlling and threatening demeanor eventually brings Michelle to escape, allowing her to come across
message is clear—buy these shoes. Whether or not that message is being conveyed in the most appropriate or effective ways is less to be desired for. The shoes are not even in the center of the picture, and in my opinion, the shoes are not the main focal point in the ad. Instead, the focus is on a woman leaning backwards on some sort of board with a very skimpy bikini bottom and loose top. She is holding a purse and has on several large bracelets, and is spraying a hose of some sort. But even all of

Goya kept from using light colors expect for the focal points. In my opinion, there is more than one focal point or that the focal point is large, from Saturn’s face to the lifeless body. The corpse is hanging in Saturn’s tight grip is deathly white and has bright blood red where the head and arm had been. I think that is a symbol, the body
Although the modern McDonald’s ad and the vintage McDonalds ad are both superior advertisements for McDonald’s, the vintage ad is better because it has a better focal point, theme, prominent element, artistic choices, and feeling or mood. In comparison to the new ad, the focal point is much better in the 1965 ad because it shows a clearer focal point. The first thing the viewers see in the old ad is the large McDonald’s sign and the classic car sitting in the parking lot. This could bring back memories
Investigating How Length and Width of Copper Wire Affect the Current of a Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some
Living with curly hair can be, shall we say…challenging. Most curly girls know what it’s like to spend hours crafting the perfect hairstyle, only to go outside, and have the humidity totally ruin it. It’s super frustrating. But even with all of its challenges, curly hair really is a blessing, and the more knowledgeable you become about managing it, mane, the more fun it becomes. Many tools can help aid you on the successfully managing your do. Here are the top 5 tools that every curly girl needs

First, he should place the necktie around his collar with the seam of the tie facing him. He should note the lengths of the wide and narrow sides of the tie and how low...
From wind-swept seeds to efficient flight mechanism, all animals and plants have evolved a variety of dispersal abilities and have an important role in understanding species survival and evolution. Dispersal is largely driven by needs for resource acquisition particularly to seek suitable breeding habitats. Individuals dispersing between populations aid in gene spread and as such dispersal is subject to natural selection. Three main evolutionary drivers are thought to result in dispersal - habitat

measurements needed to exist. Many short distance measurements were based on the lengths of the human body. The width of a thumb was used to resemble the inch, which we used today in the English System of Measurements. The foot, which is twelve inches, was compared to the length of the human foot; however, today it is derived to be longer than most people’s feet. The yard, which is equal to three feet, was inferred to be the length from the tip of the nose, to the end of the middle finger when the arm and
Adding decorative elements to a home can be done in many ways. One interesting option is to create a cover for any dull looking tissue box in a living room, kitchen, or other room. The cover for a standard tissue box can be made from many types of materials. One option is to use construction paper or fabric which needs to be sewn. However, the cover will need to fold up on each side of the box which is then fastened at the top. Review a few steps to make a simple tissue box cover. Fabric Tissue
Orly Katz Mrs.White IB Pre-Calculus SL 18 November 2013 Softball vs. Math The sport of softball has been played since the 1800’s, when it was first invented by George Hancock. As the game developed through the years, it became evident to not only the players, but the spectators as well, that mathematics was a crucial aspect of the beloved sport. As a softball player for many years, one begins to see the connections between the two very clearly. When investigating the degree of importance math has
