My parents were married in the forties. Their wedding took place at 0700 hrs. This was followed by a wedding breakfast and the whole shebang was finished before lunch time.
They were catching a train in the evening for their honeymoon and the photographer had 6x9 contact sheets of the four rolls of film used that they took away with them.
So obviously even then with fibre based paper, photographers were battling a time limit.
I have one of those proof sheets and my other siblings have most of the others. What I find quite incredible is that these proof sheets wouldn't have been subjected to archival methods, they were just rushed through.
Yet they have survived a long time being kept in the worst type of situations.
I think one of the keys for fast darkroom work, is consistency in the way you expose and develop your film. I myself have printed for many years using f stops for printing, this speeded up my printing quite considerably, as well as saving on materials.
I have checked out the RH designs equipment and I think I will gain more speed and even less waste than now, by purchasing one. All I have to do is work out how to afford one. I will get one, before the year is out though.
Be warned though, purchasing their equipment doesn't mean that you will be faster and/or better, unless you incorporate a good basic printing strategy.
I'm not saying that the equipment is dodgy, just talking from personal experience from my early days in colour printing.
It was accepted by me and my friends that purchasing a colour analyser would fix all of our printing problems, it didn't and it will not unless you accept that you have to know how to use the equipment as it's designed.
If you do a search on the forum you will find some excellent advice from people who have asked the same question and gotten some great information, which in fact was the reason I decided to by one of their enlarger timers.
