The OECF is the relationship between theoptical input and the image file code value outputs of an electronic camera. The property allows OECF valuesdefined in ISO 14524 [17] to be stored as a table of values. The following table shows a simple example of measuredOECF data.Table B-5: An example of measured OECF dataLog exposure Red output level Green output level Blue output level-3.0 10.2 12.5 8.9-2.0 48.1 47.5 48.3-1.0 150.2 152.0 149.8Minimum F-Number: This field specifies the minimum lens f-number of the camera or image capture device.Example:Trilinear1600120040400.11.01.00.20.90.950.30.80.85GreenRedBlueGreenVersion 1.0 © 2000 Digital Imaging Group, Inc. 33
