All CCD cameras collect one thing: Photons. The result is a matrix containing a number of photon counts per pixel. As a result, a CCD camera is neither black and white, or color. It is simply a “photon recorder”. To get information from our target, and to make color pictures, we use Filters. These block certain EM Wavelength passbands, and allow others through depending on your specific need. We will introduce Filters that help us achieve our goals, here.
Here we introduce one of the two standardized set of filters you will use on projects with BRIEF: SLOAN ugriz.
