GIF animation of an Apollonian sphere packing with transparent background. Transparency in computer graphics is possible in a number of file formats. The term "transparency" is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be ...
E-4 processed film is color stable for about 30 years. [ 6 ] The process largely was phased out in 1976 with the introduction of the E-6 process , which is more environmentally friendly due to its lack of toxic chemicals.

The special effects of the 1991 American science fiction action film Terminator 2: Judgment Day were developed by four core groups: Industrial Light & Magic (ILM), Stan Winston Studio, Fantasy II Film Effects, and 4-Ward Productions. Pacific Data Images and Video Images provided some additional effects.
The Pulfrich effect is the effect that covering one eye with transparent but darkened glass can cause purely lateral motion to appear to have a depth component even though in reality it doesn't; even a completely flat scene such as one shown on a television screen can appear to exhibit some three-dimensional motion, but this is an illusion ...
Hitchcock used the Schüfftan process for scenes that took place in the British Museum in his film Blackmail. In the same film, Schüfftan used a variation of this process so that the miniature set (or drawing) was shown on the reflective part of the mirror and the actors were filmed through the transparent part.

A cel, short for celluloid, is a transparent sheet on which objects are drawn or painted for traditional, hand-drawn animation. Actual celluloid (consisting of cellulose nitrate and camphor) was used during the first half of the 20th century. Since it was flammable and dimensionally unstable, celluloid was largely replaced by cellulose acetate.
The moiré effect also occurs between overlapping transparent objects. [5] For example, an invisible phase mask is made of a transparent polymer with a wavy thickness profile. As light shines through two overlaid masks of similar phase patterns, a broad moiré pattern occurs on a screen some distance away.
