Unable to get even borders on a scanned 35mm neg
matting a digital photo. opening in mat is 5.5 x 8.5. trying to get a 1/2" border evenly on all 4 sides between image and edge of mat window. able to get 2 sides same dimension and top and bottom be the same but cannot get all 4 sides the same.
wondering if it's because the image is from a scanned 35 mm neg.
thanks.
Harvey
