Technical Modeling Photography

photography was originally monochrome, most of these photographs were black and white modeling photography. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its “classic” photographic look. It is important to note that some monochromatic pictures are not always pure blacks and whites, but also contain other hues depending on the process. The Cyanotype process produces an image of blue and white for example. The albumen process, first used more than 150 years ago, produces brown tones,  some full color digital images are processed using a variety of techniques to create black and whites, and some manufacturers produce digital cameras that exclusively shoot monochrome.

Optical aberrations occur when points of the image do not translate back onto single points after passing through the lens, causing image blurring, reduced contrast or misalignment of colors (chromatic aberration).  Lenses may also suffer from uneven, radially decreasing image brightness (vignetting) or distortion.  Try moving your mouse over each of the options below to see how these can impact image quality for extreme cases, Many will say that focal length also determines the perspective of an image, but strictly speaking, perspective only changes with one’s location relative to their subject.  If one tries to achieve the same subjects filling the frame with both a wide angle and telephoto lens, then perspective does indeed change because one is forced to move closer or further from their subject.  For these scenarios only, the wide angle lens exaggerates or stretches perspective, whereas the telephoto lens compresses or flattens perspective, The following table provides a overview of what focal lengths are required to be considered a wide angle or telephoto lens, in addition to their typical uses.  Please note that focal lengths listed are just rough ranges, and actual uses may vary considerably; many use telephoto lenses in distant landscapes to compress perspective, for example.
