The One with the Bag of Pixels

Hello all,

Instead of modifying just particular pixels, now we have learned to modify all of the pixels in an image by changing the values of the colors associated with each pixel.

I decided to take a rather bright water color painting I made of my grandma and tone it down to a nice cool color. I did this by taking the average of all three color values (red, green, and blue) and set the original "blue" value to this new average. After that, I divided the value of red by a factor of 1.2 and multiplied the green values by a factor of 0.8.

Here is the before and after:

And to show this modification with another picture, here is a passion flower example:

 

See you in class!
