Final answer:
Raphael's 'The School of Athens' and Durand's 'Kindred Spirits' differ in their use of perspective - Raphael uses linear perspective, while Durand uses atmospheric perspective.
Step-by-step explanation:
Raphael's "The School of Athens" and Durand's "Kindred Spirits" differ in their use of perspective. In "The School of Athens," Raphael uses linear perspective to create depth and create a realistic representation of the space. On the other hand, Durand's "Kindred Spirits" uses atmospheric perspective to create a sense of depth and distance through the use of lighter colors and less detailed rendering in the background.
