6- Drying:

a- Hang the film in a place where there is no dirt or dust. And the best place in the house is the bathroom above the bathtub. Open the shower for two minutes before hanging the film to get rid of airborne dust, then hang the film with a clip. He placed another clamp with a weight on the lower end of the film to make it straight. In the case of more than one film, make sure that the films do not touch each other. A rope can be made over the bathtub, or suspended

The movie from the shower.

B - Wipe the film from the water droplets stuck to it, and the best way is by using a special film wiper or by using two soft pieces of wet sponge. Or you can use two fingers that we pass a finger on each side of the film, but make sure that your fingers are not rough so as not to scratch the sensitive surface. The scanning direction is from top to bottom

C - Leave the film to dry, then take a look at it after ten minutes. If there are some spots still stuck, dry them - not by wiping - but by absorbing them with the end of a clean tissue. When the film is completely dry, cut the two ends attached to the clips (because these two ends are usually still wet ».

Some photographers prefer to use a hair dryer to dry the film. In this case, make sure that the blowdryer is clean and your hand is dry so as not to get electrocuted, and keep the blowdryer at a distance of more than 30 cm so that the temperature of the film does not rise too much. « It is noted that drying in a hot atmosphere helps to enlarge the size of the granules.
Keep the movie.

A - Some photographers prefer to keep the entire film wrapped together, and this method exposes the film to scratches by friction, and the length of the film disturbs you during the enlargement because its tip falls over the sensitive paper. It is preferable to cut the film into equal parts. For example, a 35 mm film is cut into six equal parts, each part has six shots, and a 120 mm film is cut into three parts, each part four shots.

B- Keep the cut film in special paper or plastic bags sold at large photocopy shops, or place the film roll inside a clean plastic bag to keep it from dust, and always note that the film is only grabbed from its edges. The acids in the skin do not affect the sensitive layer, so it spoils it even.

Acidification of film in vats

Acidification of films in vats:

Some photographers prefer to develop film in vats. In this case, put the basins in a system (display solution, then stop, then fixation, then the washing basin.” The acidification is done by dipping one end of the film in the solution, then lifting this end with lowering the second end so that it is part of the film inside the solution, always moving the film inside the solution by lowering one hand and raising the other, then Reverse with a monotonous mechanical movement until the end of the specified time in each solution, and in the wash basin, and we continue
Hold both ends of the film with two clips and make sure that the parts of the film do not stick to each other. Leave the film in running water in the sink or change the water every five minutes until the wash time is over.
