← HistoryWithin Alhazen's camera obscura, which outcome resulted from restricting aperture size?
A)Sharper image, dimmer overall illuminance✓
B)Brighter image, increased chromatic aberration
C)Reduced image size, greater distortion
D)Greater depth of focus, higher contrast
💡 Explanation
Reducing aperture size in Alhazen’s camera obscura leads to increased image sharpness and decreased illuminance because diffraction limits light rays reaching the projection. Therefore, the image is sharper, however at the cost of lower brightness rather than increased aberration.
