I subsequently used this technique for developing out of date and colour film (such as with found films) with success, but using it on medium format film showed up some limitations. In the image below, there was a notable increase in the density of the negative towards the bottom of all the frames on the film, with some unevenness too. This may be due to the fact that when I first began using stand development, I mixed the developer at 20ºC; over the course of an hour's development the developer must cool towards ambient temperature, and perhaps, with convection currents, warmer developer rises in the tank and develops here more quickly.

Finally, as I referred to in my post about Kodak Technical Pan, when using Rodinal at high dilutions, there is a minimum amount of developer per film. Agfa recommended a minimum of 10ml Rodinal per film, no matter the dilution used. At 1:100 this would mean a litre of working solution. In practice smaller amounts of Rodinal work well enough (although I've had uneven development when using 5ml); I tend to use 8-9ml of developer to 800-900ml of water in a 3-reel Paterson tank, and when developing 35mm film, I place an empty spool at the bottom of the tank to raise the film being developed to its middle.

Since writing this post two years ago, I have also been using Ilfotec LC29 for stand development, as well as developing with its recommended dilutions and agitation regime. Although of different composition, Ilfotec LC29 is, like Rodinal/RO9 One Shot, a highly concentrated liquid film developer. Standard dilutions for Ilfotec LC29 are 1:9, 1:19, and 1:29; the first two dilutions can be used for a number of films in one developing session, while at 1:29 Ilford state that it should be treated as a one shot developer. For stand development with Ilfotec LC29, I have been using the same dilutions as with Rodinal: diluting it 1:100 for most films with a normal contrast curve, and developing for one hour; for higher contrast emulsions I have been using 1:120, 1:150 or 1:200 with the Kodak High Resolution Aerial Duplicating film. The results using Ilfotec LC29 for stand development are comparable with Rodinal and the negatives exhibit similar qualities.
