The formula for picture size and projection distance

L1 (ft)

=(0.062081X – 0.038676) / 0.3048

L2 (ft)

=(0.051456X – 0.038901) / 0.3048

H (in) = – 0.0848X

X: Picture size (diag.) (in)

L:Projection distance (m)

L1: Maximum projection distance (ft)

L2: Minimum projection distance (ft)

H:Distance from the lens center to the bottom of the image (in)

The formula for picture size and projection distance

L1 (ft)

=(0.067635X – 0.038676) / 0.3048

L2 (ft)

=(0.056060X – 0.038901) / 0.3048 H (in) = – 0.1741X

The formula for picture size and projection distance

L1 (ft)

=(0.082775X – 0.038676) / 0.3048

L2 (ft)

=(0.068608X – 0.038901) / 0.3048 H (in) = – 0.213072X

Note

•There is an error of ± 3% in the formula above.

•Values with a minus (–) sign indicate the distance of the lens center below the bottom of the image.
