For this assignment I took several pictures at varying levels of exposure. The short exposures have more detail in the brigther regions, but are underexposed in the darker ones. The longer exposures have more detail in the dark regions, but are overexposed in the bright ones. So, I combined the images into one in which all details are visible.
Sometimes, its hard to get everything in focus. Objects nearby may be in focus, while objects at a distance are blurry, or vice a versa. In this assignment, I take several images of the same scence with a variable plane of focus, and produce as a result an image where all the features are in focus.
Here, we have pictures of several objects where we change only the position of the light source. This lets us do several things. Firstly, we can create images with minimal shadows using only one light. Secondly, we can combine the images after changing their colors, to get images with whacky lighting effects. Lastly, we can use the movement of shadows to find the edges of objects. All this and more in this weeks exciting installment of Computational Photography Assignments!
In karate, and many other sports, form (the correct position of the body and angles of the joints) is very important. For my final project, I was interested in seeing if I could help correct my form in karate, and do so in a way more useful than a simple video. So, I've produced an overlay of all the frames of a video to show movement in one image.
