Dear DX, I would like to ask how to manually develop, bleach and fix solution.

I have developed black-and-white photos, but the color ones have not been tested successfully. The reason is that the temperature is difficult to master, and the temperature and time required for different dosage forms of liquid medicine are different. Film development should use liquid medicine with finer developing particles.

First, take four containers, the height of which is about one and a half times the width of the film. Two of them should be added with clear water, one should be prepared with developer and the other with fixer according to the instructions. Be sure to remember what the liquid is, and never mix it up.

If you develop in black and white, take the temperature of the liquid medicine as an example. First of all, you should soak the film with clear water and immerse the film evenly in the liquid medicine. Be careful not to expose the film. If it is too dark, you can light a green light bulb below 40W, and the liquid medicine is preferably flowing. You can also immerse the membrane and shake the medicine container. After about a minute, you can take it out, rinse it with the first pot of clear water and put it in the fixing solution. In the same way as above.

After the above treatment, the film can be hung up to dry and can be used to develop photos. Note that the drying temperature of the film should not be too high. If it is too high, it is easy to shrink the membrane, and all previous efforts will be wasted. Usually it should be dried at room temperature.
