Black and white photography has become an art genre in recent years. After a wide range of users became available first "soap boxes", shooting mainly on color film, and then digital cameras, many predicted the death of classic black and white photography. However, this did not happen. There are still many lovers who appreciate her dignity. Anyone who would like to tackle this independent genre of photography needs to learn how to develop film.
It is necessary
- - captured film;
- - photo tank;
- - glassware;
- - pharmaceutical or laboratory scales with weights;
- - volumetric dishes for liquids;
- - boiled or distilled water;
- - filter paper or cotton wool;
- - hair shampoo without conditioner;
- - reagents: metol, anhydrous sodium sulfite, anhydrous soda, potassium bromide, sodium thiosulfate.
Instructions
Step 1
If you are not going to make your own chemical solutions for development, order online or buy ready-made formulations from a specialized store. Before use, it is enough just to dilute them with water. The dosage is indicated in the instructions or on the package.
Step 2
Make your own stop bath solution. Dilute 20 ml of vinegar essence with water to a volume of 0.5 liters. The development time is indicated on the film box. It is set for a solution temperature of 18-20 ° C. If the temperature of the solution is different, refrigerate it on the bottom shelf of the refrigerator.
Step 3
If you wish, you can make the reagents yourself. Use a standard developer. Its composition is as follows: metol - 8 g, sodium sulfite anhydrous - 125 g, anhydrous soda - 5, 75 g, potassium bromide -2, 5 g, water - 1 liter. In 0.5 liters of water at room temperature, dissolve about 1/3 of sodium sulfite. After completely dissolving, add the entire metol. You can stir with a glass or plastic stick. Dissolve the rest of the sodium sulfite, all the soda and potassium bromide. Add water to a solution volume of 1 liter.
Step 4
Filter the solution. It is best to use it immediately after preparation, but it can be stored in a dark plastic bottle that must be tightly closed. The developer should be stored away from heat sources for no more than three days.
Step 5
Prepare the fixer. Dissolve 250 g of sodium thiosulfate in 0.5 liters of water. Add water gradually to a volume of 1 liter, stirring constantly. The solution is highly cooled. It can only be used when the fixer and developer temperatures are equalized.
Step 6
In complete darkness, rewind the captured film from the cassette onto the spool of the tank. Place the coil in the tank and close it. The tank must not be opened until the end of the photographic process.
Step 7
Pour in the developer and develop the film as indicated on the package. At the beginning of the process, turn the handle of the tank several times. During development, it is necessary to periodically rotate it slightly.
Step 8
Drain the developer back into the container and pour the stop bath solution into the reservoir. Its action lasts 10-20 seconds with vigorous stirring. This solution is prepared one time.
Step 9
Rinse the film with running water without opening the tank. This procedure takes 3-5 minutes. Pour water through the hole near the handle. Stir the contents constantly.
Step 10
Remove the water and pour in the fixer. Fastening takes 18-20 minutes. Drain the fixer back into the vessel. Rinse the film under running water for 20-25 minutes. The tank can then be opened.
Step 11
Prepare a wetting compound. Add 1 drop of simple shampoo to the amount of water equal to the volume of the tank. Immerse the roll of film in the solution for a couple of seconds.
Step 12
Hang the film vertically from a rope or bracket. Secure it with clean plastic clothespins. Dry away from light and heat sources, in a place protected from dust.
