1. Development: It is recommended to use D-23, D-76 developer D-23 low-contrast microparticle developer D-76 microparticle developer clear water (52 ℃) 750ml 750ml Mittel (Medo) 7.5g 2.0g anhydrous sodium sulfite 100.0g 100.0g Hydroquinone (Jian'an) 5.0g Borax 2.0g Add water to 1000ml 1000ml Dissolve and prepare in the above order when preparing. Use the original solution without dilution. When the temperature is 20 ℃, the development time is 6-10 minutes. The contrast of the film varies with the strength of the developing and stirring. The faster the stirring, the higher the contrast. The stirring intensity should be controlled during the development process. If necessary, the development time can be extended to increase the film sensitivity.
2. Stop filming: This is the process of stopping development. After development, the film is immersed in a 2% glacial acetic acid solution for 20 seconds.
3. Fixing: It is recommended to use F-5 acidic fixing solution sodium thiosulfate (hypo) 240.0g anhydrous sodium sulfite 15.0g 28% glacial acetic acid 48ml boric acid 7.5g potassium alum 15.0g add water to 1000ml. The fixing function is to remove the film. Photosensitive emulsions, so make sure that all these emulsions are removed. Use fresh acidic fixing solution, fixing time 5-10 minutes.
4. Washing: rinse with running water for at least 15 minutes.
5.Drying: In order to avoid water stains during drying and affect the production of photos, you can use a special sponge (foam plastic) or a large piece of absorbent cotton squeezed out of water to gently dry the water stains on the surface, and then hang it to dry, also It can be dried in a drying cabinet at a temperature of 30-40 ° C or in a clean and dust-free place at room temperature.
