Profundidade de campo.
Calcule a hiperfocal e as distâncias próxima e distante pela objetiva e pela abertura.
H = f² / (N × c) + f. Preset circles of confusion are conventional. Distances follow the optical axis. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.

Calculate hyperfocal, near and far distances from focal length, aperture, distance and circle of confusion. H = f² / (N × c) + f. Preset circles of confusion are conventional. Distances follow the optical axis. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
