An easy way to develop sheet film
Alan Clark
Alan Clark
28th December 2009
The simplest and cheapest method of developing 5 x 4 sheet film is in an open dish using the "shuffle" method. Its drawback is that it is not easy to load the sheets of film, with wet hands, one at a time, into a pre-bath of water. It also requires some skill to avoid damaging the film...

Here is how to make the Paterson Orbital bombproof!

I think his method of lifting the edges an inch is asking for trouble and can lead to uneven development round the edges caused by developer bouncing off the sides of the tray.
This is something I should have emphasised more in my original article, though I did say the agitation should be gentle.
To be clear about this, when I use a tray as described in the article, and when I use a Paterson Orbital, I lift the corners by the absolute minimum amount I can manage, i.e. no more than a few millimetres. After gently lifting one corner like this I move straight to another corner, lifting sucessive corners in a random fashion. The objective is to get the developer to move very gently. That way you get even development.

Hmmm... It hasn't happened to me yet Alan, but I do use 1:100 and 1:500 working solutions of my favourite developers. I also pre-soak for 5 minutes in water before going on to developing. The lift and put down isn't violent or quick, so maybe that is why I get no uneven development?

Richard,as you are getting even development you will no doubt stick to what you are doing as it is obviously working for you. But if anyone is getting uneven development along an edge of the sheet of film adjacent to the outside of the container, then very gentle agitation is worth a try.

Richard, I notice you list angling as your main interest. I used to live not too far from you and used to fish the Dove a lot. Happy days!

I moved here from Sheffield to be on the waterside... The Dove can be a lovely river, it is only twenty minutes away over in the next valley from my "mother" river, the Derbyshire Wye.

Thanks for the link Richard. What an interesting site; complete with black and white photographs too. I take it you are "Regular Rod". It's the ideal thing to read through as I await the start of the trout season. (All those non-fishing types on FADU don't know what they're missing!)

Richard - This isn't the only thread that refers to the Orbital: there are a couple that started more recently and you can easily Search for them.
