Semi-Stand with sheet film

[Aaron van de Sande]

What are you guys doing when you do sheet film with semi stand development? I was thinking of getting film tanks....

[Ron Marshall]

I use a Combi-Plan for semi-stand. It works well and the volume is appropriate. I have had good success with both HC-110 and Pyrocat-HD.

I`ve done semi-stand in a regular plastic 35mm tank, one 4x5 sheet at a time. Works great.

I should of specified that this would be 8x10... thanks for the replies though.

You could make your own tank for 8x10:

Aha, would be hard to squeeze a 8x10 into a 35mm tank.
Sandy King is using several open ended PVC tubes put into a larger tank with developer for semi-stand if I recall correctly, maybe you`ll find some info on it with a search.

I tried a Beseler 8x10 paper drum for stand development. It holds approximately 1500ml of developer and works well. If I want some form of agitation, I pour out approximately 3/4 of the developer and then pour it back it.

What is "semi-stand?"

Hi Aaron,

I use a 3" black ABS tube for the film. A 4 inch ABS tube for the developer. The 3" tube will float, so I use a 3" threaded cap (inside threads) with holes drilled in the top, and gently let it lower the tube for total immersion and cap the 4" tube. Lights on. To agitate I pull the 4" cap and the 3" cap then the tube floats up making it easy to grab and agitate (up and down 3 times and invert). 70ozs total solution and quite economical.

What is "semi-stand?"

Stand is no agitation during the time the film is in contact with the developer. Semi-stand is minimal agitation, say 10 seconds every three minutes, as opposed to normal regime of 10 seconds every 30 seconds.

With stand or semi-stand agitate continuously for the first minute to prevent uneven development.

With semi-stand and dilute developer, the developer will exhaust in the highlights during the stand phase, leading to a compensating effect that can be used to help control a large contrast range and prevent highlights from blocking. The effects achived depend on the length of the stand phase and the dilution of the developer. Development times must be extended approximately 50% and testing should be done to determine optimal times and dilutions.
