Hello again
What effect if any would IR/UV/other leds have on the NDVI results.
For example; use an (IR?) Led to shine on foliage in cameras field of view. The foliage pictured then recieves the same light as all other pictures.
Would it provide an absolute value considering all pictures recieve same light. Would light need to be brighter than ambient to serve that purpose?
Main question is what leds to use? Can get very bright LEDs of a wide range of wavelenghts
Using a handheld MAPiR with Blue filter
Thanks in advance
