Attach one end of the apron to " C " by means of the metal hooks which are to be engaged with the lugs on the axle (Fig. 2 ) . The corrugated side of the rubber bands are to be beneath the apron when it is attached. Turn to left on axle " C " and wind entire apron onto axle, maintaining a slight ten sion on apron in so doing by resting one hand on it.
Insert film cartridge in spool carrier (Fig. 3), close up the movable arm tight against end of spool. Have the black paper ( "B" in Fig. 1) lead from the top.
Break the sticker that holds down the end of black paper, thread the paper underneath wire guard on axle " D " (Fig. 4) and turn slowly to right until the word " stop " appears on black paper.
Now hook apron to lugs on axle " D " in precisely the same manner that you hooked the opposite end to axle " C " except that axle " D " turns to the right (Fig. 5).
Turn handle half a revolution, so that apron becomes firmly attached, and put on cover of box. Turn axle " D " slowly and steadily until black paper of cartridge, film and apron are rolled up together on axle " D ". As soon as this is completed the handle will turn very freely.
The developer should now be prepared and placed in the solution cup. (See page 76.) Now remove cover from box and draw out axle " D " ( Fig. 6 ), holding apron and black paper with other hand to keep end of apron from loosening.
Remove entire transferring reel (which now contains apron and black paper) which is freed by pulling out axle " D and insert immediately in the previously prepared developer.
Having filled the solution cup as directed, lower Transferring Reel into cup, either end first (Fig. 7). Let reel slide down slowly. The operation of removing reel from box can be done in the light of an ordinary room, but, of course, for safety it is well that the light should not be too bright. The total length of time for development is twenty min utes. Allow development to proceed for about
too minutes with cover of solution cup on ; then place the cover on the cup (Fig. S), putting lugs on cover into grooves and tighten cover down by turning it to right.
Now turn the entire cup end for end and place in a tray or saucer to catch any slight leak from the cup. After seven minutes reverse it so cover will be up. At fifteen min utes again invert the cup. Turning the solution cup allows the developer to act evenly and adds brilliancy and snap to the negatives.
The wire lifting rod is to be used for lifting the reel out of the cup, Hook on to the cross bar in one end of reel. When the end of reel containing cross bar is at the bottom of cup, the lifting rod is just long enough to catch the cross bar.
The fixing solution should be prepared while the film is developing.
When development is completed pour out developer and fill cup with clear cold water and pour off, repeating this operation three times to wash the film. Then remove reel, separate film from black paper and place immediately in the previously prepared Fixing Bath.
The film may be separated from black paper in light of an ordinary room, if the developer is thoroughly washed out.
The operation of separating film and black paper should be done over a bowl or bath tub or sink.
When the black paper does not free itself readily from back of film, split the paper where possible ; this will remove the hard outer surface of the paper, the remaining portion will soon become soaked and can then be removed easily by rubbing gently, while immersed, with the ball of the finger. This adhering of the black paper to the film is almost invariably caused by the use of a too warm developer.
The operations of fixing, washing and drying are precisely the same as with dark room developed negatives. See pages 79 and So.
