The actual situation depends on the fluorescence intensity. Take it out as soon as you see anything, or the film will be too dark.
After adding fluorescent agent, the reaction takes about one to four minutes. Carefully put the film into the cassette. Never move the film after it is put away, or the fluorescence will disappear. Cover the film with plastic wrap and lay it carefully. Put the prepared film on the film and don't move after sticking it. And then tabletting.
The tabletting time can be roughly determined according to the initial fluorescence brightness. Generally, obvious fluorescence bands can be seen. Press for 30 seconds first.
When developing, the film should be completely immersed in the developer. You can use a transparent or white box to observe the development. When you see a black belt on film, development is basically ok. In a few seconds, it can be fished out. Just wash it with clean water and put it in fixing solution.
