Man with the camera

filmtips:

A snapshot is popularly defined as a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent. Snapshots are commonly considered to be technically "imperfect" or amateurish--out of focus or poorly framed or composed. The term derives from the snap shot of hunting. Common snapshot subjects include the events of everyday life, such as birthday parties and other celebrations; sunsets; children playing; group photos; pets; and the like.

The "snapshot camera" tradition continues with inexpensive point-and-shoot digital cameras that fully automate flash, ISO, focus, shutter speed, and other functions, making the shooting of a good-quality image simple. Such cameras are typically programed to achieve a deep depth of field and high shutter speed so that as much of the image is in focus as possible. For expert photographers, who are better able to control the focus point, the use of shallow depth of field often achieves more pleasing images by blurring the background and making the subject stand out.

Dubbing is the post-production process of recording and replacing voices on a motion picture or television soundtrack subsequent to the original shooting schedule. The term most commonly refers to the substitution of the voices of the actors shown on the screen by those of different performers, who may be speaking a different language. The procedure was sometimes practised in musicals when the actor had an unsatisfactory singing voice, and remains in use to enable the screening of audio-visual material to a mass audience in countries where viewers do not speak the same language as the original performers. "Dubbing" also describes the process of an actor's re-recording lines spoken during filming and which must be replaced to improve audio quality or reflect dialog changes. This process is called additional dialogue recording, or ADR for short. Music is also dubbed onto a film after editing is completed.

Interlacing

Video can be interlaced or progressive. Interlacing was invented as a way to achieve good visual quality within the limitations of a narrow bandwidth. The horizontal scan lines of each interlaced frame are numbered consecutively and partitioned into two fields: the odd field consisting of the odd-numbered lines and the even field consisting of the even-numbered lines.
Abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is often specified as 576i50, where 576 indicates the vertical line resolution, i indicates interlacing, and 50 indicates 50 fields (half-frames) per second.

In progressive scan systems, each refresh period updates all of the scan lines. The result is a higher spatial resolution and a lack of various artifacts that can make parts of a stationary picture appear to be moving or flashing.

A procedure known as deinterlacing can be used for converting an interlaced stream, such as analog, DVD, or satellite, Deinterlacing cannot, however, produce a video quality that is equivalent to true progressive scan source material.

• Video quality is measured in lines of resolution, the number of tiny horizontal stripes of color the playback uses to fill your TV screen. As you can see by this table, digital camcorders blow every previous tape format out of the water.
  All camcorders, TVs, and VCRs have the same vertical resolution; this table measures horizontal resolution.)
