Aphotographer wants to capture polaris, the north star, and the surrounding stars without capturing any “star trails” caused by the rotation of the earth. he needs to use a long exposure (keep the shutter open for an extended period of time) to ensure that the stars show up bright and clear, but he will need his camera to rotate at the same rate as the earth to prevent the star trails from appearing in the photos. stars appear to rotate about polaris at a rate of 1 4 ° per minute. you can use this rate to write and solve equations. the photographer says that the stars will rotate a total of 15° while his camera shutter is open. the equation 1 4 s=15 , where s is the length of time in minutes the shutter remains open, represents this situation. how long will the photographer’s camera shutter be open?

Can u me on part c? the arcs in the photo at the right appear to be paths of stars rotating about the north star. to produce this effect, the photographer set a camera on a tripod and left the shutter open for an extended time. if the photographer left the shutter open for a full 24 hours, each arc would be a complete circle. you can model a star’s “rotation” in the coordinate plane. place the north star at the origin. let p(1, 0) be the position of the star at the moment the camera’s shutter opens. suppose the shutter is left open for 2 h 40 min, with the arc ending at p`. a. what angle of rotation maps p onto p`? b. what are the x- and y-coordinates of p` to the nearest thousandth? c. what translation rule maps p onto p`? i have the other two questions answered but i included the rest for context. i only need c.

What does the exposure compensation function of a digital slr camera do? a it allows the user to make adjustments before pressing the shutter to make the resulting photo lighter or darker. b it allows the user to choose the aperture, while the shutter speed is set by the camera. c it allows the user to choose the shutter speed, while the aperture is set by the camera. d it allows the user to keep the shutter opened manually, allowing for a long exposure.

Basics of photography if you are interested in learning the art of photography, you'll want to use a 35-mm camera with no automatic aids. that way you have complete control over how your photos will look. much of the art of photography is about capturing light. to get a good photo, you need to know how much light to let into the camera. too much, and your photo will be a pale image of what you wanted. too little, and it will be overly dark. getting just the right amount of light for your photo depends on three factors. first, there is the type of film. films come in different "speeds," which refers to how quickly the film reacts to light. the usual film speeds are 60, 100, 200 or 400. the slow films, such as 60 and 100, require more light and are used when shooting outdoors in bright conditions. when taking pictures in dimly lit areas, such as indoors, a fast film is the appropriate choice. these films don't need much light. you should use a fast film for moving objects, as well. fast film will produce a crisper image. the second and third factors are shutter speed and the size of the lens aperture. think of a camera as a box that protects the film from light. the more light that hits the film, the lighter your photograph will be. light comes into the camera through a round opening, called the aperture, that can be made bigger or smaller. the aperture is covered by the shutter. when you press the button to take your photo, the shutter uncovers and then covers the aperture, letting in the light. when you change the speed of the shutter, you change the amount of time that light comes into the camera. to expose your film to the right amount of light, you need to adjust the shutter speed and the size of the aperture. for indoor shots where you need a lot of light, you can use either a larger aperture or a slower shutter speed. for daytime shots outside in bright sunlight, you can use a smaller aperture or a faster shutter speed to reduce the amount of light entering the camera. in addition, if you want to take a picture of moving objects, you'll need to use a faster shutter speed - otherwise the image will blur. question 2 of 40 suppose you want to take pictures of your friend's soccer game. how should you prepare your camera? set the aperture to the largest opening. set it at a low shutter speed. load it with a fast film. nextreset
