A filter is a lens accessory. You add it over your lens’ end. You would use one for many reasons. With a lens filter you could correct the colors in a photo, protect your lens, change the contrast, reduce glare, polarize, and much more, depending on the type of filter. There are also color, macro and UV filters. For example, if you are taking a black and white photograph you can add a red filter to increase the contrast.
1. What is a polarizing filter? What benefits does one have for photographs?
A polarizing filter is a type of filter. It has many effects on photos. You can improve your saturation, and reduce reflected light. Depending on the position of the sun, camera and the filter, the effect can be greater or lower. Circular polarizing filters still allow the meter and

What is one piece of equipment that should be used, if possible, for panoramic photography (in addition to the camera)? Why?
One piece of equipment that should be used with the camera in panoramic photos is a tripod that can still rotate the camera. In panoramic photos you want the picture to stay level but you also need the camera to rotate. A tripod can help you take the picture.
3. What is contrast?
Contrast is the difference from dark and light or white and black in photos. In tonal contrast, the difference is between highlights, light, and dark tones.
4. What are color filters used for? What effects might different colors have?
Color filters are usually used to enhance a specific color in a picture. If lighting changed certain colors, you can use a color filter to enhance the color. For example a green filter can help contrast shades of green allowing you to differentiate them. If you use red in a black and white photo the contrast will be more noticeable.
5. Which file format is recommended for black and white photographs? Why?
It is recommended to shoot in RAW. It helps you while in the editing process. It allows you to edit better which allows you to increase or decrease the
Photographs are able to give many points of view as well but by changing the lighting it could seem to have been shot at a different time of day; change the angle and it could look like a completely different thing. Although these two combined would make a great story, photographs alone aren’t always enough or reliable; they could be taken out of context and misinterpreted by the public. Because the fact that photographs are easier and have many ways of being manipulated, they don’t really apply to the ethos, pathos and logos of a narrative, which is why a narrative is more important to a story.
Color can be viewed based on three different dimensions. The Munsell color system classifies colors based on hue, value, and chroma. Hue describes the color family or underlying tone (e.g., green, blue, red). Value describes the brightness or darkness on the scale on zero to ten, zero being white and ten being black. Chroma describes the saturation or vividness of a color. The appearance of teeth is affected in three ways by whitening. First, whitening reduces the amount of chroma in the tooth—the pigment or intensity of color is reduced. Second, whitening changes the hue, or color, or the teeth. Thirdly, whitening changed the value of the teeth.

Before delving into the philosophy of color and the questions posed by different pieces of art, the biological basis process of HOW color is seen should be explained. The retina is a neural sheet, containing the photoreceptors called rods and cones that is located at the back of the eye. Between the retina and the optic nerves leading to the brain are a series of cells that create a lateral inhibition network of the light/dark signals from the photoreceptors (1). This throws away a lot of the information generated by the photocells and gives the brain a "picture" of the edges of light and dark. The contrasts are created, leaving the brain to fill in the rest. Color vision is even more complex. Cones (the light adapted photoreceptor) contain three different photopigments, red, green, and blue, each corresponding to a particular wavelength of light (2). Color is a property of three things: the ratio of red/green activation, blue response, and value or lightness (3). The brain utilizes visual inputs to determine each of these, thus generating the characteristic color.
Gaussian filter is exclusively used for this purpose as the mask is simple. The standard convolution method is performed once the mask is calculated. Since the convolution mask is usually much smaller than the actual image, the mask slides over the image , manipulating the pixels in the image. The large width Gaussian masks are not preferred as detector's sensitivity to noise is low and moreover, the localization error in the detected edges also increases with increase in Gaussian mask width.
Before you can make a picture, you have to have a camera. Some of you already have a camera, in which case I will be showing you ways to use your camera more effectively. Others may want a new camera, or you may not have a camera at all. Before you can truly shop for a camera, you need to know what you need.
According to Elizabeth Walling (January 8, 2011), colors can be used to influence emotions and the feelings around us. That’s why something so simple like the color of a room affects people in several ways including the way they feel. The color red may trigger passionate feelings of anger of exposed to the color in a long period of time. The color green may calms others as it reminds them of nature. In conclusion, Elizabeth Walling says that it impacts our lives whether if it's a negative or a positive result.
There is an abundance of ways light and color can play tricks with how your body thinks. Color has an impact on everything. When you walk into a restaurant and instantly become hungry is one way that color has an influence. When you feel antsy in one room and calm in the other is another way that color has an effect, this is all because of the atmosphere of that room, which is altered by color.
Light is what lets you experience colour. The pigment of the retina in your eyes is sensitive to different lengths of light waves which allows you to see different colours. The wavelengths of light that humans can see are called the visible colour spectrum.
Colors. Colors are grouped according to their wavelengths. Colors with longer wavelengths such as red, orange and yellow are perceived as warm colors. Colors with shorter wavelengths such as blue, purple and green colors are perceived as cool colors. White, grey and black colors as perceived as neutral colors.
Now that we have established color as a storytelling tool, we can begin to talk about color for aesthetic reasons. The following information on color palettes comes from the article How To Use Color In Film: 50+ Examples of Movie Color Palettes by Mary Risk. Color palettes are the major colors used in a film. There are five main color palettes; monochromatic, complementary, analogous, triadic, and discordant. Also, although these color palettes are used mainly for aesthetic purposes, that does not mean that there are no psychological elements.

What do you consider art? Paintings, sculptures, drawings, or maybe something else. I know, when I think of art, I think of photography. Photography Is used for business, science, manufacturing, art, recreational purposes, mass communication, and more. Photography is using light to do amazing things, and some people think of photography as a story that just needs to be told. Ansel Adams probably believed this. He said, “You don’t take a photograph, you make it.” Photography has a long interesting history, like the fact that the word photography is made up of two greek words, photos meaning ‘light’ and graphein which is ‘to draw’ ! Photography also has some complicated techniques to get a hang of taking good photos. Have you heard of the rule of thirds? Or do you know how a camera works? Well, that will all be explained. Maybe, by the end you will take up photography too. This essay will explore the history and types of cameras and the basic rules for taking photographs.
In the world of fascinating sights, colors are all are found everywhere in all sorts of ways. Colors are put into categories and types depending on what one is looking at. Some categories of colors may include: value-tints/shades, complementary colors, analogous colors, cool colors, warm colors, and neutral colors. The types of colors within these categories include: primary, secondary, tertiary, complementary, analogous, active and passive colors. These types and categorizes can be seen in a circular diagram that is divided by hue, saturation, and value called, the color wheel. The color wheel consists of all colors that are within the visible spectrum. The electromagnetic spectrum A basic color wheel includes: red, orange, yellow, green, indigo, and violet. As one looks cl...
Photography is a word derived from the Greek words “photos” meaning light and “graphein” meaning draw. The word was first used by John F.W Herschel in 1839. It is a method of recording images by the action of light, or related radiation, on a sensitive material (Bellis, N.D).
