How are film photos developed?

Film photographs are developed in this way:

After shooting on location, the film is post-processed in the darkroom. Post-processing includes developing the film, printing the photos, and cropping them. Learning photography, you should also understand and master the basic techniques of darkroom operation.

The darkroom, also known as the darkroom, is an opaque, specialized room for film processing and photo production. The darkroom is usually divided into two parts: the dry area and the wet area. The dry area is placed in the printing box, enlarger and other facilities for printing and enlarging

Wet area is mainly for the preparation of potion, developing, fixing and washing and other operations. The basic requirements of the darkroom are impervious to light, orderly arrangement of equipment, convenient water supply and drainage, quiet, no vibration, stable power supply, good ventilation, and it is best to maintain a constant temperature.

Basic equipment for developing color film

1, developing tank. Developing color film can not be developed as black and white film, the use of disk display method, because the color processing temperature requirements are very strict, in the development of the disk is not easy to control the temperature of the development of the film is not easy to oxidize the liquid very quickly, and also easy to bruise the emulsion film.

2, darkroom or darkroom bag. Darkroom or darkroom bag is indispensable equipment for developing photographic materials. Developing color film is best not to develop black-and-white film with the development of a darkroom and other equipment, because the development of black-and-white film used in some of the liquid, will have irreparable consequences on the color film.

3, thermometer. Color film processing process on the temperature have strict requirements, color negative C-41 process and color reversal film E-6 process, are required to process at a high temperature of 38 ℃, and the temperature to be strictly controlled. Therefore, the thermometer is one of the important tools in color processing.

4, timing. Processing color film processing time, can not develop black and white film that has a great deal of scalability, but there are very strict requirements, therefore, the clock is necessary. This clock should have a second hand, it is best to ring the bell at regular intervals. Some can be timed to ring a small calculator, can also be used for color processing clock.

5, constant temperature water bath. The current color film processing are required at high temperatures, C-41 and E-6 process temperature is 38 ℃. Therefore, in the development of color film will need to have thermostatic equipment. Can be used thermostatic water bath box medicine thermostatic vessels.

6, the preparation and preservation of the medicinal fluid appliances. Preparation and processing of liquid first need to have a more sensitive and accurate balance, due to the color development of liquid drug requirements are strict, so the accuracy of the balance can not be low accordingly.

7, other appliances. There are a number of other appliances, should be prepared in advance before rinsing, so as not to cause rinsing due to the appliances are not ready to produce busy or accident. For example, the film clip and scrubbing rags, etc., are essential. When a second exposure is required, a strong light bulb should be prepared in advance.
