In The Public Media
Design of fullface masks (underwater, land, gasmasks) in movies is sometimes constrained by desire to show the actor's face to the camera. There have been cases of fullface masks used in movie filming having a light inside shining on the actor's face so the face shows on camera better: a feature that is no use whatever in practical breathing mask use.
In Fantastic Voyage the diving sequences were filmed using Italian ARO oxygen rebreathers with the mouthpiece (and diving mask) replaced by a pseudo fullface mask not intended to be dived in, because the diving actors were out of water suspended from thin wires.

Famous quotes containing the words public and/or media:
“The study of tools as well as of books should have a place in the public schools. Tools, machinery, and the implements of the farm should be made familiar to every boy, and suitable industrial education should be furnished for every girl.”
—Rutherford Birchard Hayes (1822–1893)
“The media have just buried the last yuppie, a pathetic creature who had not heard the news that the great pendulum of public conciousness has just swung from Greed to Compassion and from Tex-Mex to meatballs.”
—Barbara Ehrenreich (b. 1941)
