When developing film, which is better, a hand jar or a stirring rod?

Compared with the stirring rod, the precision of hand-cranked pot is better, and attention must be paid to the treatment of stains when operating.

In the process of film development, it is necessary to pour the developer into the water tank, soak it for 3~5 minutes to cover the film, then pour it out, and then stir it evenly in the water tank 10 second to improve the sensitivity of the film. Film is the carrier of exposure and image acquisition in a camera. Film photography is also a display of physical tones. Many images will be developed during shooting. Hand washing will cause problems such as uncleanness, opacity and uncleanness, which will affect the imaging quality of photos. Washing with a stirring rod will not cause these problems.

What are the tips in the operation?

I want to wash it with a hand jar. If you don't know its usage very well, I suggest you wash it with a steam humidifier. The steam humidifier can fully heat the steam to evaporate the water on the surface of the film, thus ensuring that the developed film will not produce bubbles. There are many types of steam humidifiers commonly used in practical use, such as high temperature steam and high temperature steam. When washing with steam humidifier, pay attention to keep a certain distance between steam humidifier and steam.

What should I pay attention to when washing by hand? Hand jar? And then what? Stirring rod? The application of methods and skills.

In the process of film development, we must grasp patience and accuracy. In daily life, we can improve the quality of photos through repeated practice. Of course, in the process of washing, we should also use soapy water reasonably to enhance the aesthetic feeling of the photos. It is best to choose stainless steel for the hand-cranked water tank, so that the film will not get sticky when cleaning. Moreover, the stainless steel material is not easy to get oil, and the hand-cranked fuel tank is not easy to be damaged. The stirring rod is mainly made of stainless steel. If water vapor leaks during washing, the stirring rod will automatically open the seal. This can completely remove the water vapor, dirt, dust and other dirt on the film without affecting the quality of the photo.
