High Speed Photography

This type of photography is all about taking very fast images at a very fast phenomena. High speed photography is defined by any set of photographs captured by a camera at 128 frames per second or greater, and of at least three consecutive frames. High-speed photography can be considered to be the opposite of time lapse photography. High speed photography is seen to freeze the motion. An photograph will be taken at a high fashion speed rate/ shutter rate. To create this image of freezing a motion. This methods requires a sensor with a good shutter system and strobe lighting. The first practical application of high speed photography was taken by Eadweard Muybridge in 1878 where he carried out an investigation to see if a horses feet ever were all off the ground when the horse ran. There are three types of high speed cameras are: Intermittent motion cameras, which are a speed-up version of the standard motion picture camera using a sewing machine type mechanism to advance the film intermittently to a fixed exposure point behind the objective lens, Rotating prism cameras, which pull a long reel of film continuously past an exposure point and use a rotating prism between the objective lens and the film to impart motion to the image which matches the film motion, thereby canceling it out, and Rotating mirror cameras, which relay the image through a rotating mirror to an arc of film, and can only work in a burst mode.

Scanography

Scanography is also known to scanner photography. This is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed or also known as a` photo scanner with a capturing device. Fine art Scanography differs from traditional scanning this is because it uses atypical objects. The objects used are often 3D. This method of photography is quite new and different from anything else because The process of creating art with a scanner can be as simple as arranging objects on the scanner and capturing the resulting image. The scanner differs significantly from digital cameras in many areas. The optical resolution of a a flatbed scanner can exceed 5000 pixels per inch. Even at a relatively low resolution of 1200 pixels per inch., a letter sized image would be 134 megapixels in size. The depth of field for most scanners is very limited, usually no more than half an inch, but the built-in light source provides excellent sharpness, color saturation, and unique shadow effects. Using a flatbed scanner to scan items other than paper documents exceeds the original purpose of the scanner, so special care must be taken with the process. The bed of the scanner is typically made of glass and care needs to be taken that the glass not be scratched or cracked when placing or removing items on the bed. Since the items to be captured are often placed directly on the bed, dust and other particles will often land on the glass, and care must be taken to keep the glass clean. Scanners will also hold only a limited amount of weight, and items that may damage the scanner, such a liquids or items that might scratch the glass, should be placed on a plastic bar to protect the bed. The simplest use of the scanner, which also most closely matches its use for document capture, is as a specialized tool for
