I am considering altering the back of my 8x10 Ansco so that it can take a full rectangle of ground glass, rather than needing a glass with all 4 corners clipped back about 1". Many big cameras seem to accept a full sheet of glass, without the need for clipped corners. I am guessing that the Ansco clipped its glass corners to prevent blowing out the bellows, lens, or ground glass itself upon rapid compression of the bellows. I would rather look at a full screen of glass, unless I am overlooking some potential problems I would be creating. Thank you in advance for your comments.
