Which outcome arose in early camera obscura devices when the aperture increased without shortening focal length significantly?

💡 Explanation

Image sharpness decreased as aperture increased because the pinhole imaging acts worse; the Circle of Confusion increases with aperture growth, therefore sharpness suffered, rather than depth of field which is less sensitive.
