Color Modes

GrayScale

RGB

 This is the grayscale version of my original photo, the size of the image gets cut into a third due to the other two thirds of color being cut out of the image.

Bitmap

Index

This is my original RGB image, it has the most couples in it therefore it is the largest of all the files. This can have up to 16.7million colors in it.

This image only has two colors even though it seems like there is patches of gray it is still just pixels of black clustered together giving the illusion of gray. Due to its small amount of color the file size reduces drastically.

This is the index version of the original photo, it has 74 colors in it and has a very saturated red element to make the storage unit behind me stand out. The file size will depend on how many colors you decide to incorporate.
