Hi
I am doing a similar project to yours but instead of using NDVI as an index of photosynthetic biomass I intend to use it to detect drought stress in vegetation that has been photographed over three years being subjected to different levels of water stress.

I am very new to imageJ so I was wondering if you had any advice?

The images were captured by two cameras mounted on a structure above the plots. One camera having a visible light filter so that it captures only infrared light, and the other capturing visible light. I have registered and georeferenced etc, the images on ENVI but haven't been able to get much further. The NDVI values I have calculated have all been negative...

Cheers
