How many colors are there?
We see the world in color, hence the special realism and appeal of color photography, especially since modern digital cameras that shoot in color by default make it extremely accessible.…

Dynamic range
Light falling on the photodiodes of the digital camera matrix is converted into an electrical signal. For this to happen, the number of photons that hit each individual photodiode must…
