	The use of IR for vegetation is one of the scientific uses it is
good for. It will show you healthy plants and plants that are not as healthy
because healthy plants reflect a lot of IR, if diseased or malnourished,
plants reflect less IR and show up darker, or less red if you use EIR. I
like using HIE and EIR from a small airplane to photograph my brothers farm
fields to look for unhealthy/underfertilized areas. If he knows where to
look he might fine that the problem is a bug or a weed or something he can
spray for and he can then cure the right problem and get a larger yield in
the fall harvest. In forestry they can identify tree types by its IR
signature too. I have actually used IR to find the location of underground
field drainage tile, then if we see an area missing we can look right at the
end for a collapse or blockage and repair it. IR is a neat tool for even the
average farmer. I am going to use my Sony with nightshot from the air soon
and see how that works for me. I put my IR filter on and put it in night
shot mode and select B&W mode in the functions and it seem to work real well
on the ground, It sees right through smoke real well too!
