Final answer:
Radial composition in Phoebe's photography project likely creates an 'excited, full feeling' due to the dynamic energy and focus that radial balance and movement impart on the viewer.
Step-by-step explanation:
When Phoebe employs radial composition in her photography project, she creates a feeling of dynamic energy and focus. Radial balance suggests movement from the center to the edges or vice versa.
This movement can create a sense of excitement and fullness as the elements radiate outward or inward, drawing the viewer's eye into the composition, akin to the way Buddhist mandala paintings use symmetry and movement.
Specifically, in photography, capturing movement and direction is crucial because it adds life to still images. Thus, the kind of feeling created by using radial composition is best described as an 'excited, full feeling' which would correspond to option 4 in the asked question.
