Exempel på hur du använder F-NUMBER i en mening

• The f-number is also known as the focal ratio, f-ratio, or f-stop, and it is key in determining the depth of field, diffraction, and exposure of a photograph.
• As with other light readings, shutter speed can be changed as long as the f-number is altered to compensate, e.
• In photography, an exposure meter is a light meter coupled to either a digital or analog calculator which displays the correct shutter speed and f-number for optimum exposure, given a certain lighting situation and film speed.
• In photography, exposure value (EV) is a number that represents a combination of a camera's shutter speed and f-number, such that all combinations that yield the same exposure have the same EV (for any fixed scene luminance).
• If the PoF is to pass through more than one arbitrary point, the tilt and focus are fixed, and the lens f-number is the only available control for adjusting sharpness.
• A camera with a smaller sensor can be preferable to using a teleconverter, because the latter affects the f-number of the lens, and can therefore degrade the performance of the autofocus.
• Equivalently, for the same DoF, the full-frame format will require a larger f-number (that is, a smaller aperture diameter).
• For distances substantially less than the hyperfocal distance, the DoF is given by , where N is the lens f-number, c is the circle of confusion, and m is the magnification (Ray 2000, 56).
• In both the 'same photometric exposure' and 'same lens' conditions, the f-number is not changed, and thus the spatial cutoff and resultant MTF on the sensor is unchanged, leaving the MTF in the viewed image to be scaled as the magnification, or inversely as the crop factor.
• Due to the smaller image sensor size of the MFT system the depth of field is larger compared to full-frame sensor cameras if the lenses are operated at the same f-number.
