Open one of your own new and never submitted photos in Lightroom and make vibrance adjustments to this photo.
You should have 4 photos for this assignment.
Each photo will have a caption underneath the photo. (See my examples and do the same thing.)
Photo 1 will be the original photo with no adjustment.
Photo 2 will be with too much adjustment.
Photo 3 will be not enough adjustment.
Photo 4 will be the just right amount of vibrance adjustments.
If you do not know/remember how to do any of these assignments, find someone near you in the class that remembers that can help you. One of the 3 standards in class states that you need to be a problem solver when I am helping another student or not available.
