5 x 7 developing tank?
Having just renovated an old mahogany and brass half frame camera I 've started developing 5 x 7 sheet film in a Paterson rotary processor. The problem is that the plastic blades under the lid are leaving marks on the film. I have read about this problem but not encountered it when developing 5 x 4 film. Maybe I could cut the blades off but the processor only takes two sheets at a time and I wonder if anyone can recommend an alternate daylight tank that takes more sheets?

I think Jobo made on but I cannot remember the model number.

You could look to one of their print tanks - I've used one for processing two sheets of 8x10 film.

Thanks guys.
Trevor, have you removed the plastic fins from your Paterson? I agree it is very convenient to use and if I can get mine to work properly may get another, to speed up the job a bit. I also use open trays but my darkroom is cold at this time of year and it is convenient to use the Paterson at the kitchen sink. Alan |

Thanks Trevor.
Not sure if the volume of developer has anything to do with the problem. I always use 300mls, and rock gently by hand. As I said earlier I've never had a problem with 5 x 4 film. alan |

Alan, I use 250ml developer, just slightly less than you. I must confess I've probably processed more film in the 'finless' tank as it was nice and new when I bought it and just seems easier to keep clean.

I decided on 300 mls because experiments with surplus film and the lid off the processor showed that this much was needed to cover the curving tray bottom - and the film - at the outer edges. I thought that I was playing it safe. But it seems to me now that the more liquid in the processor the higher the film can potentially float up towards the fins, which it may well do with over-enthusiastic rocking.
I will try 250 mls, and very gentle rocking. Alan |

I'd be lost without my Jobo Expert Drum 3010 (for 4x5) I have 2 and each holds 10 sheets. They're not cheap but are excellent.
Here's the link to the different models; http://www.jobo.com/web/Expert-Drums.855.0.html

Trevor - An unused Jobo 3005? The are going for a King's ransom these days. Every time I process 8x10 sheet film in trays, one... sheet... at... a... time..., I am oh so tempted to take out that second mortgage.
