Describe how diffraction affects the s6h w8:1b wfseh oq1e:gtatement that 7+rhwxxf izmd,)4x.m the depth of field is greater and the . 4w7mz fh +mrixxdx),image sharper when a camera lens is “stopped down” to a larger f-number.
参考答案:
If a lens is stopped down
too much (too big of an f-number), then diffraction will occur as light passes
through the extremely small lens opening (the light will begin to “bend around”
the edges of the stop). This diffraction
will blur the image, especially around the edges of the film, and will lead to
an image that is less sharp.
