Separate tank for each bath

Hello
Anyone use this method?:

That is basically the classic principle of dip and dunk processing, in its automated version still employed by many commercial labs.

The idea behind the closed tanks we typically use is that one can process in light and keep things simple and spare on room.
In contrast to large open tanks intended for use with most diverse film formats, those tanks made from pipes are quite economical on processing bath volumes. But still are beaten by daylight tanks when used rotating.

Amazing how lazyness has taken over!

The only way to come to good results is—work. Labour. Human effort. That LEGO play is so far from what I can achieve by hand. I can shake off liquid and take the reel to the next bath in two seconds. I, not a device, have total control over what goes on in a bath, I have the feeling for it. No robot can duplicate that. I want to feel the film under water. Like riding a bicycle, nothing replaces the forces I sense.

I manually treat films in spirals in open containers on a commercial base. Closely nesting tanks are not a good idea. The only advantage of them is that you need least bath volumes. Okay for a single film but quite apart from the evenness I produce. One more time: stepping from one bath to another takes one to five seconds in my darkroom. Pouring one bath out and the next in simply lasts too long with daylight tanks.

Rubber gloves, lights off, film out the container, one hand on the timer button, the other dips.

One more time: stepping from one bath to another takes one to five seconds in my darkroom. Pouring one bath out and the next in simply lasts too long with daylight tanks.

But the time needed for exchanging baths in a daylight tank can be subtracted from the processing time of the preceeding bath.
