Infrared photography uses films that are sensitive to both the light we can see and some of the longer length (above 700 nm) infra-red radiation. The film is also sensitive in the UV region (below 400 nm). In the case of the Kodak HIE film it is sensitive to near-infrared radiation out to approximately 1000 nm wavelength (1 micron). There are scientific uses for such films which include forensic applications and aerial crop and forest surveys. The film is also used in the restoration and investigation of paintings.The olive is native to the Mediterranean region, tropical and central Asia and various parts of Africa. The olive has a history almost as long as that of Western civilization, it's development being one of civilized man's first accomplishments. At a site in Spain, carbon-dating has shown olive seed found there to be eight thousand years old. O. europaea may have been cultivated independently in two places, Crete and Syria. Archeological evidence suggest that olives were being grown in Crete as long ago as 2,500 B.C. From Crete and Syria olives spread to Greece, Rome and other parts of the Mediterranean area. Olives are also grown commercially in California, Australia and South Africa. There is some disagreement over when the trees first appeared in California. Some say they were introduced in 1769 when seeds brought from Mexico were planted. Others site the date 1785 when trees were brought in to make olive oil.
