It’s neat how the IR lake-photo is much clearer and much more readable in terms of tree differentiation. I can 100% see how this can be useful in agriculture/forest management and heath monitoring. I wonder what other wavelength(s) would be interesting here.

You can in the second set of photos also clearly see how dead the leaves are, the more IR they reflect, the more pink they are, the more healthy they should still be. The bottom ones on the tree are much more pink than the upper leaves
