I have to very strongly agree with that concept John. A diorama must tell a story to make it interesting and the 'fine detail', and dare I say total accuracy, are secondary. However, a diorama just by existing surely does tell a story. from a modellers perspective, there are three basic ways of presenting a model.
One is the model on a shelf. OK, it can tell a story or provoke questions such as 'What must it have been like to have been in one of those?' but generally, that is as far as it goes.
Secondly, what I call a 'scenic base' where the model is displayed on some form of flat terrain or even a photographic terrain, to put the model into some kind of real world context. This can often impart enough detail for the viewer still to wonder about the subject but now tempered with a concept of scale and environment.
Thirdly, what I call a diorama. This will consist of one or more models in a realistic 3D environmental model, the base itself. This should not only show the model but the very conditions, and in some cases accurate depictions of an event, in which it served. In effect it becomes a miniature representation of history itself. The questions that such a diorama can induce are almost endless from wanting information on the vehicle, the secondary equipment, the people represented by figures, the terrain and conditions right up to the political 'Why?' 'When?' and 'Where?'
Any diorama of the third kind must tell a story, even if that story is fictitious as in Sci Fi and Fantasy. Using models based upon real objects, times and political doctrine, a diorama can miss inform as readily as it can inform. Either way, true or false, it is by it's very being, telling a story.
To create a diorama to accurately show a real event is no more complex than a fictitious one. Obviously the detail has to be as accurate as scaling down will allow to really well represent an actual event but, given that most of these events are traditionally based on historical information, it really only represents the truth as known from the source material available and as such has to be a compromising representation of what is thought to have happened.
I think you are working on a fascinating subject that could be of great interest to many modellers, please keep us informed of your progress.
