Diffraction ratio legend
	No visible diffraction (less than 3)
	Visible diffraction may slightly impact image sharpness (3 to 4.5)
	Visible diffraction will impact image sharpness (4.5 or greater)

Camera select a camera. If your camera is not listed, request to add it here.
Filter select a filter. If a column is gray, that wavelength of light will not be transmitted by the selected filter.
- Select Full spectrum when using a full spectrum converted camera with no additional filter. If you use a full spectrum camera with an additional filter, then select the filter used.
- Select Hot mirror or UV/IR cut for an unconverted camera, as these contain a hot mirror filter, or when using a full spectrum camera with an added UV/IR cut filter.
- If you add a filter to an unconverted camera, select that filter. This should be a 720 nm or higher filter.
ƒ-stops switch between (whole) and (third) values.
- Safe shows the highest ƒ-number that you can use to completely avoid diffraction. This ƒ-number has a Diffraction ratio of 3 or lower at all wavelengths.
- Caution shows the ƒ-number that you can use with mild visible diffraction. This ƒ-number has a Diffraction ratio of 3.75 or lower at all wavelengths.
- Avoid shows the ƒ-number that will produce visible diffraction. This ƒ-number has a Diffraction ratio of 4.5 or higher at some wavelengths.
- Safe, Caution, and Avoid ƒ-stops are calculated to the one-third ƒ-stop regardless of whether you are viewing the whole stop or one-third ƒ-stop table.
- Optionally, select the row of the ƒ-stop you wish to shoot at.
