What is important about focus? How do you get good focus in a digital slr photograph? Focus is important because it affects the quality and depth of your photograph. A picture that's not in focus will look more grainy and, depending on if the background is in focus or not, will affect the depth of field. Larger-numbered f-stops, or smaller openings of the lens will create more focused images. Lower ISO will also keep that photo from looking less 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 how far back you can see in an image; depending on the focus, a viewer might see a larger depth of field or a smaller depth of field. With a larger depth of field, the viewer would be able to clearly identify the foreground, middleground, and background, while an image with a smaller depth of field might only have a clear foreground with a blurred background. This is important to keep in mind when taking photographs because depending on what your focal point is, you may want to see further back into the image or focus on what's in front.

What is the exposure triangle and why is it important to making quality photos? (HINT...there are 3 parts to the Triangle make sure you explain all three and how they relate to each other and making a good photo.)  The Exposure Triangle is composed of aperture, ISO, and shutter speed. Aperture is the size opening of the lens when the photo is taken, ISO is the camera sensor's sensitivity to light, and the shutter speed is the amount of time that the shutter is open. These elements all relate to each other in the exposure triangle because each element affects the others; Aperture affects the amount of light and the depth of field, which in turn amounts the ISO and focus of the photo. The shutter speed can affect the clarity of the photo when photographing objects in motion, also affecting the focus of the image. This is important to remember when making quality photos because the clarity and lighting of your photo can be drastically different depending on when aperture, ISO, and shutter speed settings your camera is set at.


 * What are the 5 compositional techniques we use in photography? EXPLAIN don't just list.**

The five compositional techniques include the Rule of Thirds, Framing, Filling the Frame, Level Horizon, Leading Lines, and Point of View. The Rule of Thirds is created with a grid of three columns and three rows, creating nine blocks. The intersections of the lines should be used as the focal points for interesting and complex compositions. By doing this, the subject is not in the middle of frame, allowing for informal balance within the photo. Framing is when the elements within the shot are used to frame the subject. This can include using tree branches, doorways, or whatever it may be. By doing so, depth and context can be given. This framing will also draw the eyes of the viewer to the focal point. Another compositional technique is filling the frame. This can include zooming in for a close up shot. By doing this, the frame of the photo will be filled (hence the name of the technique), allowing for a more intriguing composition. The zoom creates interesting lines and view points within the frame and subject. By using a level horizon, be it straight or even a slanting line, a unique composition is created. By positioning the horizon, a foreground, middle ground, and background can be created. This technique goes hand in hand with the rule of thirds, because the frame can be split evenly into rows using a horizon line. Through leading lines, the focal point can be emphasized. Whether it be straight or diagonal, the lines draw the eyes of the viewer in different directions, creating movement within the frame. Finally, through different points of view (ex. bird's eye view, one point perspective, worm's eye, etc), a unique composition can be created. Instead of looking at the subject head on, a different viewpoint creates intrigue and a whole new way of looking at a shot.


 * Which lighting techniques come from natural sources and which come from artificial? When would you use one vs another?**

Natural sources of light can include firelight, sunlight, moonlight, candlelight, and starlight. As said in the name, these light sources come naturally from the earth. On the other hand, artificial light can include flash from a camera, ring light, studio light, spotlights, bounce light, fill light, and even a flashlight from a phone. When dramatic lighting or extra lighting is needed, artificial light can be used. Artificial light is also used for professional indoor photography (be it still life, modeling, etc). Natural light is used outdoors mostly, however candlelight can be used both indoor and outdoor. Sometimes, natural light may not be enough, so artificial light is used along with it.


 * In terms of lighting what kinds of light sources do you already have experience shooting photos with? Explain.**

I (Kavitha) have had experience with the flash on a camera, flashlight from my phone, and most natural sources (sunlight, candlelight, firelight). When I got my senior pictures taken the photographer used bounce light, fill light, and studio light. So I guess I've had more second hand experience than with firsthand in terms of most artificial light sources. Sarah would say the same. Although, both of us have not had much experience with photography in general.
