Final answer:
In the scenario described, where a circle (the image) fits completely inside a square (the film surface), the type of framing represented is exact framing. This aligns with key framing techniques used to create balanced and engaging photographs.
Step-by-step explanation:
The concept of photospot framing refers to how the subject matter is captured within the confines of the photograph's edges, which in this case, are represented by a square (the film surface). When the circle (the image of the subject) is entirely within the square and there are no additional elements outside of the circle that are captured on the film, it aligns with the concept of exact framing. This is because the subject fits neatly within the frame with no part of it extending beyond or being cut off by the edges of the film.
Framing techniques such as the Rule of Thirds, Level Horizon, and the practice of Filling the Frame are important for creating balanced and engaging photographs. Understanding these techniques helps photographers decide how to position their subject within the frame to make the final image as compelling as possible.
