have heard no objection from teams pleying in Cleveland under this much light. In
addition to good photographic illuminstion, the spectators can see the game much
better.

Where the cost of vat anton replacement may be prbhibitive, very satis factory
film results are possible if the ordinary gymnasium bulbs are replaced by the #2
rh-toflood bulbs. Each lamp gives about 1500 Watts of light, and if there are fif+
teen or more fixtures over the floor, 16 frame /second movies may be taken with a
fast lens. Since these bulbs have a life of about 6 hours, a transformer system
to burn them at 60 volts when camera light is not necessary, will add to their life.
In this way, two full games may be played safely without danger of bulbs burning out.
Thi: suggestion may enable the athletic department with a very modest budget to have
coaching films for little cost.

Camera technique is importmt. The best motion pictures of any kind are those
shat have a steady background and the minimum of camera movenent--even in sports
filming. To achieve this result, a steedy tripod with a smoothly acting panorama
head is necessary forcsmera support. DO NOT USE THE CAMERA “FREE HAND".

A distomce from the floor that will allow the lens to include just about
haif of the floor area is very cesirable. This position should be in the balcony
or froma high place to prevent & jumble of players from obscuring the play. Shoot
down on the game. The distance necessary to include half the floor will call for
a lens setting at the INFINITY or the 50° mark,--or half way betwem the two. When
filming at an aperture of f1.9, the depth of field at the INFINITY setting will
give good focus from 44 to INFINITY and at the 50° mark, good focus from 23* to
INFINITY. The f 1.5 lens will have similar depths of field.

We found the best position for the camera to be just about opposite one or
the other foul or "free throw” ‘ines. This will minimize the camera swing neces-
sary to follow the plays from onc basket to the other, since the lens takes in half
the floor area, The camera will have to move in an arc of from 30 to 45 degrees,
whereas a center cameras position would mean 4 swing of close to 90 degrees from bas-

ket te basket. It is not necessary to move the camera for every pass or movement
