'''"Fuzzy Edges" and [[Masking]]:''' Even the most perfectly cut aperture plate will not have a perfectly sharp edge. Because the film and the edge of the plate are not on the same focal plane, there will be a slight shadow on all edges of the image.

It is common practice to over-cut aperture plates very slightly so that the shadow spills onto the masking. | '''"Fuzzy Edges" and [[Masking]]:''' Even the most perfectly cut aperture plate will not have a perfectly sharp edge.
