A practical effect is a special effect produced physically, without computer-generated imagery or other post production techniques. "Special effect" is often synonymous with "practical effect." In contrast, visual effects are created in post-production through photographic manipulation or computer generation. Many of the staples of action movies are practical effects. Gunfire, bullet wounds, rain, wind, fire, and explosions can all be produced on a movie set by someone skilled in practical effects. ==Practical effect techniques== * The use of prosthetic makeup, animatronics, puppetry or suitmation to create the appearance of living creatures. * Miniature effects, which is the use of scale models which are photographed in a way that they appear full sized. * Mechanical Effects, such as aerial rigging to simulate flight, stage mounted gimbals to make the ground move, or other mechanical devices to physically manipulate the environment. * Pyrotechnics for the appearance of fire and explosions. * Weather effects such as sprinkler systems to create rain and fog machines to create smoke. * Squibs to create the illusion of gunshot wounds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Practical effect」の詳細全文を読む スポンサード リンク
