Answer:
Joel should use blurring in order to make a part of the picture stand out.
Explanation:
Joel should use blurring in order to make a part of the picture stand out. Blurring is the effect that makes something unclear, difficult to see or to distinguish. Joel can use this effect to select everything he doesn't want to stand out and apply a blur effect to it, leaving the other part of the picture clear and defined. By doing this, the viewer will focus on the defined part, so it'll catch his eye easily.
