Computational photography

Computational photography refers to using advanced image processing techniques to improve the images captured by cameras. Instead of focusing on optical processes and image capture methods, computational photography uses software to manipulate visual data. Applications include high dynamic range imaging, panoramic images, image relighting, and light field cameras.

Let's look at the following image:

Look at those vivid colors! This is an example of a high dynamic range image, and it wouldn't be possible to get this using conventional image capture techniques. To do this, we have to capture the same scene at multiple ...
