It is known to use 'bag-in-box' arrangements both for supplying photographic processing solutions to a photographic process and for collecting effluent therefrom. However, a supply 'bag-in-box' arrangement may not be completely emptied and when it is transferred to collect effluent, and it may become full before the new supply 'bag-in-box' arrangement has been emptied. This is a problem if there are no empty 'bag-in-box' arrangement to replace the full one collecting effluent. Described herein is a 'bag-in-box' arrangement (10) having a variable effective volume. The arrangement (10) comprises an outer box (12) in which is housed an inner bag (20). Connection to the process is achieved by means of connector (22). A spacer element (28) is located in the top of the outer box (12) which limits the effective volume thereof for transportation. The element (28) is removed when the 'bag-in-box' arrangement (10) is connected to the process to supply solution thereto. Once the inner bag (20) is emptied, it is transferred to collect effluent from the process. The inner bag (20) can now expand in the outer box (12) to substantially fill it thereby providing a larger volume for collection of effluent. In this way, a supply 'bag-in-box' arrangement will always be empty before an effluent 'bag-in-box' arrangement becomes full.
