Re: Photographing trees in autumn with Konica IR

[Chris Eastwood <c.eastwood@xxxxxxxxxxxxx>]

HiYa

One of my lecturers at Uni was doing IR's of foilage (colour and B&W) for
the CSIRO in the attempt to detect differences of foilage caused by pest
attact on the plant.

He reckoned that even with carefull bracketing and differing development
(trying to get a gradient) that there was not much to be had ... even with a
densitometer.

bummer

So any tonal variation in leaves within one species of tree is likely to be
as much due to surfance reflectance changes as anything else (like dust,
angle, surface sheen blah blah blah)

2 cents worth
