In this week's Design Blog I wanted to share what I learned this week. I feel that I’ve learned an abundance of things just in the first week of class. Just a brief reminder coming into this class, I knew little to nothing about photography let alone how a camera actually works on capturing an image. For example, light entry, aperture, and shutter speed. I chose these three examples because they are very crucial to taking a photo.
Light Entry
Light entry is when you press the shutter button and light from the scene enters the camera through the lens. Light entry is very important when taking a picture because it directly influences the exposure, clarity, and overall quality of the image. The exposure is the amount of light that enters the camera and affects how bright or dark. The final image will be for example too much light will cause over exposure where little light or darkness will be under exposed.
Aperture
The aperture controls how much light passes through the lens. A wider aperture lets in more light. While narrower, aperture lets in less light. Aperture is one of the other main reasons photographers use different lenses on their cameras. Aperture also affects depth of field, which is the range of distance in a photo that appears sharp,for example, a wide aperture creates a shallow depth of field, while isolating the subject from the background mainly used for portraits. A narrow aperture increases depth of field, keeping more of the scene and focus, which would be more ideal for a landscape photo which would be more ideal for a landscape photo.
Shutter Speed
The shutter opens for a specific amount of time that allows light to hit the sensor or film. A faster, shutter speed freeze motion while a slower shot of speed can capture motion blur. Shutter speed can be manipulated for artistic effects such as light trails in a long exposure photograph where moving lights are captured overtime or sports events where fast pace movements are being photographed.
