However, the photographs he produced no longer exist and therefore the earliest surviving aerial photograph is titled 'Boston, as the Eagle and the Wild Goose See It.' Regardless of controlled or uncontrolled and no matter which software used, a good mosaic requires some sort of color matching between the stitched images in order to conceal the seams. Thus, IR-sensitive film operates beyond the confines of the visible spectrum and can be used to detect information that is unavailable for human vision. This range encompasses the near-IR band in addition to the near-UV and visible wavelengths. The hillslopes at the top and bottom are dotted with small terraces recently installed for a reforestation project; two patches with pine trees left of the image center are the remains of an earlier, failed reforestation attempt. It provides a tonal rendition that closely approximates the brightness of the scene being photographed and can be used to distinguish between objects of truly different color. It is a means of fixing time within the framework of space. Normal color films are sensitive primarily to wavelengths of the visible spectrum and provide a color rendition that approximates the original scene as it would be viewed by the human eye. 2 Items that are about the Topic Aerial photography in geology. 2).
