Dialectical Anthropology, 2009
It is, of course, well known that if we focus a camera on an object at some definite distance from the camera lens, there will be a finite range of distances in front of and beyond the focused object in which everything appears acceptably in focus, while outside that range everything becomes progressively more blurred at increasing distances from the ...

This chapter investigates the field of contemporary French documentary as a source for cultural representations of farmland and farm life, a segment of the national territory that has undergone profound change in the past half-century. Farmland, which represents over half of the surface area of metropolitan France, provides employment to an ever ...

IEEE Symposium on Information Visualization, 2001. INFOVIS 2001., 2005
We present a new technique called Semantic Depth of Field (SDOF) as an alternative approach to focus-and-context displays of information. We utilize a well-known method from photography and cinematography (depth-of-field effect) for information visualization, which is to blur different parts of the depicted scene in dependence of their relevance ...

Beams with large depth of field
The Journal of the Acoustical Society of America, 2000Acoustic bullets, also known as limited diffraction beams, are solutions of the scalar wave equation with the property of maintaining their shape upon propagation, without spreading in space and in time. A necessary and sufficient condition for the generation of acoustic bullets is presented.

Depth of Field for the Presbyope
Optometry and Vision Science, 1981As a general rule the near addition (add) for a presbyope is selected so that the range of clear vision is dioptrically and not linearly balanced. Implicit in such thinking is the assumption that the dioptric and linear range of clear vision cannot be simultaneously balanced.
