Self-study
Camera manufacturers typically advertise their products by citing the resolution of their cameras' lenses, the resolution of a lens being the degree of detail the lens is capable of reproducing in the image it projects onto the film. ███████████ ███████ ███████ ██ ████ ███████ ███ ██████████ ███ █████████ ████████████ ████████ █████ ███ ██████ ██████ ███ ██ █████████ ████ ████ ███████ ███ ████ ██████ ████ ███ ████ ████ ███ ████████████ ████ ██ ███████ ██ ███████████ ██ █ █████████ ██████
Summary
The author concludes that differences in camera lens resolution are irrelevant for practical photography. Why? Because all modern lenses project far more detail onto film than any photographic film can reproduce in a developed image.
Notable Assumptions
What if differences in resolution could be important to some aspect of practical photography besides the amount of detail projected onto film? The author assumes that there’s no other way in which differences in resolution could be relevant to practical photography.
This isn’t a question where I’d go in with a specific prediction about what the author assumes. Let’s keep an open mind.
