884 HANDBOOK OF PROJECTION FOR
A SERIOUS ERROR. — One fundamental error found in most examinations is that the examiners seem to recognize only one danger to the public, and that is the danger of fire. The truth of the matter is that with modern projection room construction, and the fact that the public now very generally understands that it is in no real danger from a projection room fire, the fire danger lacks considerable of being of as much importance as is danger of injury to the eye-sight through eye-strain.
There is no more eye-strain in a properly projected moving picture, projected under proper conditions of auditorium lighting, than there is in reading this printed page in good light, but if the projection be unintelligently done, or if the auditorium lighting be wrong, there may be very serious eyestrain. It is therefore of very great importance that the examination include a really competent investigation of the knowledge of the projectionist as applies to the optics of projection.
It is quite true that fire danger was what first brought about the licensing of projectionists. It is also quite true that at that time danger to the audience from film fire was a real one because projection rooms were not then thoroughly fireproof. Also in that day newspapers went to great length's in what seemed an endeavor to impress the public the danger to audiences from film-fire, which action on their part was very largely responsible for the causing of wild panic the instant a projection room fire became visible to the audience.
Improvement in both projection machinery and projection room construction and the education of the public to the fact that there is little or no danger to them from a projection room fire has changed all this, whereas increased brilliancy of projected light and other things have made the item of eyestrain, set up by improper procedure, of very greatly increased importance. It is therefore rather absurd to hold an examination covering only electrics when optics is in many •ways now the more important.
The licensing power ought also to be deeply interested in the knowledge of the projectionist as to auditorium lighting, since not only may the value of what the audience pays its money to see be greatly lessened by improper lighting of the auditorium, but mistakes in lighting of the auditorium while the picture is on may operate to set up literally tremendous eye-strain to the audience, or to portions of the same.
Only the competent man will be able to keep the projector
