I'm sure the curators would disagree, but I think quite a few museums have lost their way when it comes to displaying their contents. Increasingly I find buildings where the displays are pared down in a minimalist way, the "educational" is promoted very heavily, and there seems to be an emphasis on style rather than exhibits.
The Victorians got a lot right with their approach: pile in as much as you can, label everything, add a few panels to give background information and an overview, and leave the rest to the visitor. One of my favourite London collections is the Sir John Soane Museum. It holds the artefacts amassed by the neo-classical architect, and though it was put together just before the Victorian period, it follows their approach to display.
In my youth I visited York reasonably regularly, and in that city the Yorkshire Museum was a magnet for me because of its collection of stuffed birds. Courtesy of Victorian "collectors" (whose methods of shoot and stuff I deplored) I got to see many species that I would otherwise never have set eyes on. Not only extinct birds such as the Great Auk, but also the extreme rarities that pass your way only occasionally or never. These were usually presented singly or in groups in glass cases. There seemed to be room after room of such exhibits, broken up with the odd diorama showing a bird, such as the black grouse, against a painted backdrop of its habitat, with a few plants and rocks scattered about. In fact, that was my introduction to the word "diorama", and its a word I only occasionally came across in subsequent years. Today, in museums, the diorama as a method of presentation seems to be viewed as old hat.
However, the word has made a comeback courtesy of photography. By a trick of lenses and software, people have devised a way of giving a real scene the appearance of a diorama. By adding foreground and background blur the impression of a shallow depth of field such as is found in close-up photography is achieved. This tricks the brain into, on first viewing, seeing the photograph as a set with models: see examples here and here. I understand that the Olympus PEN range of cameras have the facility to create these built into them as an effect. The only question I have is, "Why?" I can see that it's a trick that is easily done, but what is its purpose? I can't think of a use to which I would put it, so its reason is lost on me.
What has my photograph of the top of a yew hedge* against a blue sky with white clouds got to do with dioramas? Well, it occurred to me that the photograph could be mistaken for a view of the jungle-covered hills of somewhere such as New Guinea. Which would make the image something akin to a "reverse photographic diorama"!
