Shooting Faults

When observing and shooting luminous objects (lanterns, moon, etc.) through a mosquito net, they can take the form of a cross.

In modern cameras used a method in which produced a few shots that are "mixed" to provide the viewer the most accurate picture. It's called HDR (High Dynamic Range).

This effect is due to the fact that the lenses some digital cameras use plane shutter, which can be roughly represented in the form of slits, moving from one image edge to another.

Aberration of optical system — error or error image in the optical system caused by deviation of the beam from the direction in which he would have to go in a perfect optical system.

When manyred party rewrite on film video can produce the effect similar to double exposure. On nowyou recording superimposed particles neudenau old.

There are different shooting modes for various video cameras. In particular, they may vary the number of frames per second. There may be more than the standard 25 or less.

To receive color photographs should be done for two shots. One black and white, high resolution, and the second lower-resolution, but in color. Further the obtained color image is stretched and applied to the black-and-white as a texture. Such action is necessary because due to the different refraction of light rays of different spectrum when passing through the atmosphere from the color image of high resolution from space do not work. These features form the image are almost not noticeable on stationary objects, but clearly distinguishable when the shot fall fast moving objects such as planes or cars.

Panoramic photography in particular, photography, obtained by the technology of assembling panoramas from individual images (in this case it may have a small angle and a standard aspect ratio).

The graphics artifacts are unwanted features of the image appearing in certain conditions.

The compression artifacts

Digital camera Canon EOS 7D in 2009 was an interesting glitch.

The lens consists of a set of lenses (in some lenses - of mirrors), designed for mutual compensation of aberrations and assembled into a single system.

Full or partial conversion of coloured images result in over-exposed.

A special device, which is that the same frame is exposed ("photographed") several times.

There are a number of defects specific to film images. They are connected with the peculiarities of the film and principle photo.

Often it's a small point on the photos, like hovering metal ball. At least - this is quite a big blur.

When the objects are out of focus, their silhouettes blurred and poorly recognizable. They can look like dark or colored translucent stain.

Most often this artifact is called skayfish if the lens gets a passing bird or insect.

Reflection of the flash on objects and small living creatures that are out of focus at the time of photographing.
