Saturation

Saturation can be defined as the degree of purity and brightness within a color. Using photo-editing software, such as Photoshop, you may adjust an image to increase or decrease the saturation level.

Adjusting the saturation of an image using Photoshop.

  1. Open Photoshop (or any photo editor).
  2. Open terminology/Demos/colorPicture.jpg.
  3. On the Layers panel, choose to create a new Hue/Saturation Hue/Saturation Icon adjustment layer.Hue/Saturation on Layers Panel
  4. Take a moment and try out a few alterations and note the changes in the image. Always use caution as we are trusting our human eyes and the monitor to make adjustments. This image may look very different to another person on another monitor.

  6. Adjust for more saturation.Saturation Adjustment
  7. To make sure we are not altering the image too much, I like to use a tool that adjusts based on the math, instead of my eyes. For example, you may use image variations if you have the Windows version of Photoshop (if you are using the Mac version, please skip this section as there is not an equivalent option in your version. You may have the option if you are able to launch Photoshop in 32-bit mode on your Mac OS):
    1. Select the background layer in the layers panel and hide the Hue/Saturation layer.
    2. Click Image > Adjustments > Variations.Image Adjustments Variations
    3. Click the Saturation radio button.Saturation Radio Button
    4. Notice the More Saturation preview has many blue areas. These show too much saturation and the implied suggestion is to click the opposite, Less Saturation to even out the image and make the best print possible.More Saturation
    5. Click the Less Saturation and then click OK.Less Saturation
    6. Save the image as "PicnicIslandForPrint.psd" and close the image.
