I hope you find this free workbook useful. You may give a copy to any other photographer that might be interested. However, if you bundle this workbook with any other materials, charge for it or change it in any way, it'll tick me off plenty! Don't do it!

I don't guarantee everything included to be correct and it was virus free when I uploaded it to my web host.

If you have comments, problems, or want to report a bug or mistake feel free to email me.

*The Digital Camera option assumes a Lens Maginifaction Factor in the neighborhood of 1.5 to 1.6. For example, a 50mm lens for a 35mm camera would provide be approximately equlivalent to a 75mm lens on a 35mm camera. Consider it a rough estimate for Digital SLRs.

Hyperfocal distance is the nearest point to the camera in acceptable focus if the lens is focused at infinity (i.e, the near limit). If you focus at the hyperfocal distance, everything from one-half the hyperfocal distance to infinity will be in acceptable focus.

CALCULATE MAT BORDERS

INPUT: MAT AND WINDOW DIMENSIONS

Enter the Outer Dimensions of the Mat:

Height: 16.00Width: 16.00

Enter the Dimensions of the Window

Height: 12.00Width: 10.00

OUTPUT: MAT BORDERS

To Place Window at Absolute Center the Borders Are:Fractions

Decimals (nearest 1/16)Top & Bottom: 2.00 2

Sides: 3.00 3

To Place Window at Optical Center* the Borders Are:Fractions

Decimals (nearest 1/16)Top: 1.63 1 5/8

Bottom: 2.38 2 3/8 Sides: 3.00 3

Measurements can be entered as decimals or fractions. When using fractions insert a space between the whole number and the fraction. For example: 7 1/2

Your imput will be converted to decimals, but output is available in fractions.

*ABOUT OPTICAL CENTER: This will move the image closer to the top than the bottom. The formulas I used are based on a diagram I once ran across for placing the image at optical center. Unfortunately, I can't remember the source. You might want to sketch the results to see if you like the result before cutting a mat.
