Craig:Subject eminates form stray light bouncing off lens
thru bellows, etc. It's an equipment issue. See Davis" text for discussions. The program has a .02 flare density
as a default, but one can change it in the Winplotter (WP) prgm. I believe it's only used in the incident system.
Zone shooters ignore it. It may be taken into account by the initial Zone system film speed calibration. In Davis' earlier work, all BTZS density data included B+F density. As his ideas progressed, he made compromises and the WP no longer uses B+F. In part it may be the result of current films which show higher B+F than earlier versions. Send me an Email if you have any ?'s regarding testing, EFS, etc. Ben Wilbur
