Assignment $3$B:

Image Color Depth: In Assignment $1,$ we learned that each pixel of a computer image is

represented with three values, RGB$.$ If we add transparency, we would have RGBA $($A$$ for

alpha channel$).$ Traditionally one byte is used for each color, meaning that each pixel takes up $4$

bytes of space. These are known as $8$ bits per color channel encoding, or $8$ BPC for short. More

recently, encodings with larger ranges of color have become popular with artists and

photographers. Programs like Photoshop now support $16$ BPC and $32$ BPC encoding
