Hue and Saturation

Original

The purpose of this exercise was to experiment with Hue and Saturation to see how each affects an image. Above is my original image. This is a picture of my younger brother, Colby. As you can see he is wearing a red shirt and a red sweatshirt. The background appears to be a road. First, I opened the image in Photoshop. Then, I adjusted the hue to +81. This caused the road in the background to change to a greenish-blue, Colby's hair to a shade of green, and his jacket and lips to a neon green. This image is shown below.

Hue

After reverting back to the original image, I adjusted the saturation to +67. This caused the sun hitting the left side of Colby's face to become brighter and everything else in the image appears more vibrant. The image showing this is below.

Saturation

It is interesting to see how hue and saturation can affect an image. Krause defines hue as "another name for color" and saturation as "the purity of a hue" (p. 209). This idea is shown in my images. Adjusting the hue caused my image to turn green and adjusting the saturation caused the colors in my image to become more vibrant.
