Can I develop my own film photos? How to wash it? Are there any specific conditions?

1. Tools needed: developing powder, washing tank, stationary liquid, paper treating agent and stabilizer.

2. Find out the developing powder used to develop the film, mix the developing powder with a cup of hot water and stir it in a container, but be careful that the temperature of the water is not too high, 50 degrees, but not lower than the body temperature. The developed powder needs to be completely dissolved in water.

3. Prepare another glass, pour distilled water into 1500 ml, take out the bleaching fixative, open it and pour it into water, constantly stirring, constantly adding water, and adding 2000ml. It should be noted that do not use metal cups.

Compared with the first two steps, the third step is very simple. Find a set of stabilizer powder and melt it with 2000 ml of water.

Find the developing sink in the washing machine, divide the sink into different parts according to the instructions, and rinse it with hot water.

6. Adjust the reel on the film so that the reel can be loaded into the card slot for development. When the film was opened, there was an extra card in the card slot.

7. Don't expose your film after you roll it into the darkroom, otherwise everything will be in vain. The light here comes not only from outdoor sunlight, but also from indoors.

8. Next, put the film into the card slot and pour the developer into the pool to soak for three to four minutes. Pay attention to completely cover the film with developer, and then pour fixing solution and stabilizer for cleaning.

9. The last step is to dry the paper.

Imaging principle

The image is projected onto the film along this optical path.

Camera imaging schematic diagram

The focus adjustment system and shutter system in this module are connected by lens 1 and electronic shutter. Driven by the motor, the lens is set to 1, the shutter moves back and forth, and the focal length is adjusted to get the clearest image. The exposure time is controlled by the shutter.

Image collection

Film camera uses silver salt (mainly silver bromide AgBr) photosensitive material attached to plastic film as carrier. After the film is shot, it needs to be developed to take pictures. In the process of shooting, you can't know whether the shooting effect is good or not, and you can't delete the photos.

Film cameras are divided into monocular cameras and binocular cameras, and cameras are negative, so in terms of cost, consumers need to recalculate the cost of buying film, developing a painting, developing film and photographic paper, and the cost of each negative film is about 60 yuan, while that of positive film is about 40 yuan.

There is no difference between digital camera and film camera in principle, because they both transmit or reflect the light of the object through the lens and image on the focal plane.
