Patricia Fay Morgan asked the Naked Scientists:
I am currently working on a cross disciplinary PhD in fine arts and environmental issues and what I have been interested in doing in the fine arts part of my research and something that I have been interested in my own art work for many years is the idea of 'visualising' unseen forces in nature. I have for example placed an ultra sonic recording devise next to a tree and was interested to hear the sounds that were there.
I have also used heat emission video in an ‘art experiment’ with myself and tree, though that wasn’t very successful because trees and humans are such different heats. I then heard that all living things emit emf’s and I wondered if you could visualise emf’s from trees and humans? I have recently been to speak to a physicist at UNSW the University that I am currently working at and I was really interested to find out that while there were many sophisticated machines to detect electromagnetic waves there wasn't any way to 'see' them. (I am not a scientist and new to this field so I could be wrong here).
One of the reasons that I am interested in this and in the context of my PhD, which intersects fine arts and environmental issues - was that I was thinking if you could 'visualise' some of these unseen forces - like weak emf's for example or magnetic fields or vector fields (sorry I know very little about what is out there in the unseen world), that you might be able to show some form of communication between humans and for example trees?
I would be interested to hear your answer - it might be that it crosses biology, physics and electrical engineering?
Kind Regards, Patricia

Kirlian photography can produce striking images of plant leafs (see links below).
However do not be misled: the aura is made by the high voltage used to create the image, it is not innate energy within the leaf.
A Kirlian photograph can be made of anything living or dead, the effect depends on electrical conductivity, (e.g. dry leaves produce poor auras).
A kirlian photograph (a form of contact print photography involving high voltage) shows a corona effect around the perimeter of a leaf.

Kirlian photograph of a leaf of the Kangaroo Vine (Cissus antarctica), showing the electromagnetic discharge around the edges.
This luminous discharge is the result of high-energy interactions between the subject and a powerful applied electric field
(in this case 32,000 Volts).

Healthy vegetation strongly reflects infrared (IR) radiation.
IR photographs of trees are eye-catching ...
