I have been interested in photography since the
1950s. In the 1960s and early 70s (working with fully
manual cameras) I enjoyed capturing night scenes, one of
which won a national competition. The prize was an
auto-exposure SLR, a technology that was not overly
helpful for long exposures due to reciprocity failure. Wet
streets following rainfall were often a key ingredient of
the nightscapes, a consideration that would reappear for
thermal imaging over 40 years later.
My training and profession have involved a range of image gathering techniques ( X-ray crystallography, photomicroscopy, corona discharge photography and autoradiography etc). Geophysical methods of investigation often involve logging soil resistance or magnetic data points, one at a time, which are used to form an array of 'pixels', which is then refined through appropriate processing to form an image. Both within and outwith the visible spectrum, imaging is mass data point collection and should be performed under optimal conditions (for the technique of choice) and the resulting images processed to extract the maximum amount of inherent information. Standard photographic visualisation is only a starting point.
