a numerical measurement that represents the size of the lens aperture and determines the amount of light that enters the camera

"F-number indicates aperture size."

"The f number represents the ratio of lens focal length to aperture diameter where smaller numbers mean larger openings."

a visual artifact that occurs in digital photography when a fine, repetitive pattern in the subject, such as a fabric or a grill, interacts with the camera's sensor and produces an unintended, wavy pattern in the final image

"Moire pattern creates weird wavy lines."

"Moire patterns appear when a scene contains fine repetitive details that interfere with the camera sensor's pixel grid."

a common optical aberration that occurs in photography when different colors of light are refracted differently through a lens and fail to converge at the same point
