Marz - Lighting and Composition Questions    What is important about focus? How do you get good focus in a digital slr photograph?   Focus is an important aspect of photography because it will determine how sharp, blurry, clear, or grainy the photo will turn out to be. Focus can be altered by other aspects, like the depth of field, the aperture, and the shutter speed. To get good focus in a digital slr photograph, you will need to select autofocus points that you want the camera to focus on whatever points you desire, and pressing the shutter button half-way down to focus on those points. This will ensure that the photo is sharp rather than grainy.   Explain in your own words what depth of field is and why it's important to understand when shooting photos.   Depth of field is, essentially, how much of your photograph will be in focus after you shoot it. It is important to understand that the depth of field will impact the way that the shot turns out, because there are different types of depth of field to consider. A large depth of field will result in a large amount of the photo to be in focus, while small/shallow depth of field will cause only certain parts of the shot to be in focus, while the rest is out of focus. If you were trying to take a shot of a landscape as a whole, then a large depth of field should be used, but if you wanted to focus on one specific thing, like a flower petal, then a shallow depth of field should be considered.   What is the exposure triangle and why is it important to making quality photos?   The exposure triangle consists of three aspects—ISO, aperture, and shutter speed—which all impact the quality of a photograph. ISO is the measurement of the camera’s light sensitivity, and the lower this measurement is, the less sensitive the image is to light, and the sharper the image will be. When shooting in bright conditions, a low ISO setting will help to enhance the quality of the photo by making it more clear, but a high ISO could be considered when shooting a sporting event so that the action can be more clearly seen. The next part of the triangle, aperture is the measurement of the size of the opening of the lens. Much like the iris around the pupil, aperture controls how much light gets into the lens when taking a photo, and affects the depth of field as well as the focus of the image. A higher setting of aperture will decrease the depth of field, causing only certain parts of the image to be in focus, while a low aperture will increase the depth of field, causing more of the image to be in focus. The final part, shutter speed, is the amount of time that the camera is exposed to the scene as the photo is taken. To shoot a quality still image, a faster shutter speed should be used. To capture the motion of objects or people, a slower shutter speed should be considered to capture the blur of this motion. Together, these things all impact the quality of the image, which is why they are all important to keep in mind. <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="color: #801000; font-family: 'Trebuchet MS',sans-serif;">What are the 5 compositional techniques we use in photography? <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> The compositional techniques used in photography are rule of thirds, framing, filling the frame, level horizon, and leading lines, as well as considering an interesting point of view, and the focus and depth of view. The rule of thirds asymmetrically cuts the image into thirds horizontally/vertically, and these intersecting points are considered to be the points of the most interest. Framing utilizes aspects of the shot to frame the points of emphasis in the shot, like if a person stood in a doorway. For filling the frame, the subject/object of interest should fill up the majority of the shot, putting more emphasis on this compared to other aspects in the shot. When creating a level horizon, the camera should line up horizontally along with the horizon line. Leading lines also add dynamic by leading viewers into certain parts of the frame, drawing attention to these points using these lines. An interesting point of view should also be considered, because by viewing the scene from a unique perspective, photographers can draw attention to specific things. Focus and depth of view are also important when trying to clearly highlight the scene as a whole, or only making certain parts of the shot clear. <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="color: #801000; font-family: 'Trebuchet MS',sans-serif;">Which lighting techniques come from natural sources and which come from artificial? When would you use one vs another? <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> Lighting techniques that come from natural sources are sights illuminated by naturally occurring lights like the sun, the moon, or the light from a campfire. This can also occur inside, when the scene is illuminated by available light from the outside, or by candlelight. Natural light can be used to capture nature landscapes, or to allow for a more natural setting. Artificial lights are sights illuminated by created lighting sources, like the flash of a camera, a studio light, or light from a lamp. Artificial light can be better manipulated than natural light, and can therefore be used to form dramatic lighting to add emphasis to one specific aspect of the photo, which natural light would not be able to do, or when trying to fill all of the light spaces so that the subject is illuminated from all sides. <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="color: #801000; font-family: 'Trebuchet MS',sans-serif;">In terms of lighting what kinds of light sources do you already have experience shooting photos with? Explain. <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> I am familiar with natural lighting, because I have taken many outdoor photographs where the sun, or part of the sun, illuminates the trees or the road or the landscape as a whole. When inside, I have used available natural light to take pictures of myself or of others, and have found that this displays the subjects a little more naturally and less dramatically. I have also taken photos filled by artificial light from my lamps, which I find that I have to manipulate at times to display my subject more clearly. <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;"> <span style="background-color: #ffffff; color: #801000; font-family: 'Trebuchet MS',Helvetica,sans-serif;">
