Following are examples of unprocessed photographs comparing a stock Canon ELPH300 camera to our NDVI version.  

Keep in mind that for the ELPH300NDVI camera, the color channels are mapped where

bulletRed = Near Infared
bulletGreen = Visible Green Light
bulletBlue = Visible Blue Light

Processed images were created with ImageJ and our custom aNDVI7_MKII macro which maps NDVI values to various colors where

bulletGreen is highest NDVI value
bulletYellow is under green
bulletRed is under yelllow
bulletPurple is under red
bulletBlack is under purple

NDVI calculation is a modified version of the traditional NDVI calculation which we call Enhanced NDVI or ENDVI.  For this example, we used:

ENDVI = (Red + Green) - (2 * Blue )) / ((Red + Green) + (2*Blue))

The reason for this is that both the Red (Infrared light) and Green (Visible Green) should reflect light for a healthy plant.  Blue is normally absorbed by a healthy plant.  By summing the Red (Infrared) and Green channels together, we get a better signal than when just using the infrared signal alone.
