This graphic should print out correctly using your normal print settings for a 4X6 print.

Print out on plain paper first to check scaling. The correct size places
the center of the infinity symbol just below the f/16 line on the right and on
the left the f/16 line should be in the center of the "0" of the "10" on the foot scale.
Resize in your photo editor if printing is not the correct size.
The graphic can also be reversed and printed on clear acetate, then spray the back white and you now have white letters on the reverse side with the acetate on the top for protection. Use double stick tape to adhere to the lens
