This is due mostly to the fold of the cloth over the seam allowances. Thicker piecing thread can give you a thicker "fold over" allowance when pressing. To get the "scant" part, actually sew a couple threads narrower than a true quarter inch if needed. The general rule is to never sew over an unpressed seam. You may find finger-pressing faster and safer than conventional pressing.

A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film , for either stills or filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape. In the case of motion picture film, the format may also include audio parameters though often not. Other characteristics usually include the film gauge , pulldown method, lens anamorphosis or lack thereof , and film gate or projector aperture dimensions, all of which need to be defined for photography as well as projection, as they may differ.
