FOREGROUND/BACKGROUND
THE BIG AND SMALL OF
PERSPECTIVE MODEL PHOTOGRAPHY
AKA “YES, VIRGINIA, SIZE REALLY DOES MATTER!”

T
his entry in my blog is an attempt to explain what I’ve learnt about an aspect of model photography that is absolutely crucial in achieving that sought-after realism that modellers strive for after completing their miniature masterpieces. I’ll be the first to admit that I’m no expert on the matter and that there are people out there who have had infinitely more success than my meagre efforts, however I have gained a bit of knowledge on the subject and would like to pass on any relevant titbits to those of you who may be interested in improving your photographic efforts.
Forced Perspective viewing, essentially the art of using larger scale props, models, etc. in the foreground and smaller scale items in the background to enhance the apparent distance between the two was probably first employed in stage shows and plays hundreds of years ago. A small stage in front of the audience, however the illusion of much greater distances could be achieved using perspective in front of a painted backdrop. Viewed from a specific position (ie. the audience) the illusion of great depth and distance could be inferred with a minimum of effort and stage area. The same was still very much true with the introduction of still cameras, followed by movie film and finally the advanced video cameras of today – viewed from essentially one angle, straight on, the audience is controlled and limited into seeing only what the photographer wants them to see, that of a realistic horizon and great depth of view, just like in real life. Of course, in a stage setting with live actors performing a play, a “willing suspension of disbelief” is employed by the audience so their enjoyment of the performance is not hampered by the instinctive knowledge that what can be seen is not necessarily the whole truth.

 For model makers, working in a variety of scales comes as second nature; 1:144, 1:72, 1:32 and 1:24 for aircraft, 1:72, 1:35 and 1:16 for tanks and AFVs, 1:24 for cars and trucks, etc.... Combining these varying scales into one still photograph can be extremely rewarding when viewing the finished result. I’m reminded of a visit to the Australian War Memorial in Canberra many years ago where I saw, firsthand, the amazing realism and simulated “depth of viewing” that some of the battle dioramas managed to accomplish. I vividly remember seeing larger (1:20 or even 1:12 scale?) soldiers in the foreground, with diminishing scales of other figures and vehicles filling in the background areas, along with a painted cyclorama at the rear, creating scenes that possessed such an incredible realism that one had to look twice to ensure that an actual war scene hadn’t been photographed. In effect, these dioramas are “shadow boxes”, model scenes that can only be viewed from a particular angle, with careful lighting used to help sustain the illusion of depth and distance. Use your search engine to locate the boxed dioramas of Shep Paine, one of the masters of this forced perspective technique in model making. His work is absolutely stunning to say the least. In the past I have had plans to create some shadow box dioramas, however they failed to see the light of day. 
One of the best movie examples of the use of forced perspective to create the illusion of size disparity is Disney’s “Darby O’Gill and the Little People”. Released in 1959, the film is chock full of Special Effects, with special mention being made of the forced perspective shots that occur when Darby (Albert Sharpe) visits the leprechauns in their underground kingdom. To call these shots intriguing, even amazing, is an understatement. They are intricate and undetectable, combining live actors in two separate planes to create the illusion that Darby is walking amongst tiny people. No CGI, no blue screen used at all, a few foreground puppets and just the placement of a normal sized actor in the foreground, with other actors in the far background to show the apparent size difference between the two. The shots are still mind boggling today.

From "2001: A Space Odyssey"(1968), these are
a combination of photographic cutouts and
 miniature landscapes, built in forced perspective
 style (ie. larger in the foreground and much smaller
in the background) and positioned in  front of the
camera so as to appear far more distant and
vast than they actually are. The live action
segments, the Earth and stars are all separate
exposures and matted in afterwards. The total
depth of the miniature sets was apparently only
about six feet (2 metres).


A further use of perspective photography occurs in Stanley Kubrick’s “2001: A Space Odyssey” during the Moon Bus sequence on the lunar surface. Apparently, to create the effect that the landscapes were of a much larger size than they really were, photographic cutouts of the rolling plains and mountain ranges were lined up, one in front of the next in front of the cameras and carefully modelled and dressed to appear to cover thousands of square kilometres of the lunar surface. To the camera the illusion was complete, however when viewed from above the miniature landscapes appeared too narrow and squeezed.

A recent example of perspective in film occurs in “Lord of the Rings: The Fellowship of the Ring” in Hobbitown when Gandalph is sitting at the table with Frodo.

perspective photography being
effectively used.
Two different sized tables were employed, along with food, decorations and cutlery, to show the diminutive stature of the Hobbits compared to normal human beings. Along with tracking shots by the camera and very careful lineups, the effect is simple and startling. Forced perspective setups are used extensively throughout the “Lord of the Rings” trilogy.
These examples are just three mentions of a technique that is employed in many motion pictures, even in this day and age of computer generated backgrounds, action scenes and complex special effects.


For Derek Meddings and his talented team of model builders and technicians working on the puppet shows of Gerry and Sylvia Anderson in the 1960’s, forced perspective photography was an absolute necessity. Filming on model stages no bigger than a few metres in length and width required the use of many varying scales of miniatures to enhance the illusion that a far larger area was being photographed in 35mm film. With a huge sky cyclorama in place along the back wall of the stage, moveable tables were set up in the foreground and the landscape sets were built according to what could be seen through the lens of the camera. What the landscape looked like to the naked eye was relatively unimportant – the essential viewing was done through the lens to achieve a sense of depth to the scene. Various model buildings and vehicles would be placed on the landscape according to their scales and to what they looked like through the camera. In early shows such as “Fireball XL5”, “Stingray” and “Thunderbirds”, car and vehicle scale was generally about 1/24 in order to use existing model kits. In later shows like “Captain Scarlet” and “Joe 90”, vehicles of up to 1/12 scale were used for greater realism and more added detail.


All of these shots from various Gerry Anderson shows
have one thing in common. They all utilise forced
perspective to achieve their look of realism - larger scaled
vehicles in the foreground and smaller scaled examples
in the background.




Buildings were constructed, mainly from plywood and other timber, in these scales to accommodate the vehicles, while other structures were produced at a much smaller scale to fill in background areas. In the near foreground, closest to the camera lens, might be placed a couple of larger scale tree branches or some additional structures. Built in horizontal levels, the miniature set may consist of anywhere up to five or six differing scales of models – from the extreme rear - the sky cyclorama, painted horizon, sloping background or mountain range, midground level areas, foreground sections and closeup foreground pieces – total depth, about five to six metres. The apparent depth would essentially be infinity, ie. as far as the eye (camera lens) could see.
To illustrate this use of forced perspective in a model situation that can be achieved in a garage or large garden shed, I offer the following photographs of a setup I constructed for my latest video venture called “Dogfight!” To emulate the setups of Derek Meddings and his team, I had to construct the following necessary items – a large sky cyclorama, six metres long and three metres high; a distant horizon cutout made from plywood sheet; sloping hills for the background, two table tennis tables converted to shooting platforms with the addition of rolling castors; and a sloping foreground of 2mm styrene sheet. All this was done over a period of a year and a half, along with the construction of vehicles, aircraft and buildings in varying scales – 1/72, 1/35 and 1/144 being the most common used. As well as all those, larger scale wing and weapons pod sections were constructed for two of the aircraft featured, at around 1/16 scale.
The basic framework consists of 25mm PVC piping.



It took a lot of blue paint to cover the 18 square metres.

The sky background, as stated, is about six metres in length, which just fits into the allotted space in my shed! The horizon is 2.8m long and about 16cm tall at its highest point. It consists of a long piece of hardwood, with the plywood cutout screwed to the facing edge. The sloping hills are 2.5m long, consisting of plaster-soaked cloth over a chicken wire and timber framework, with sifted soil and sand added with white glue. To further the effect of distance, I have laid a long strip of wedding veil (thule) over both the horizon and rolling hills. This tends to create an atmospheric haze which is apparent in real life. The table tennis tables, two of them on castors, are 2.8m by 1.5m, although one of them is a welded creation to match the size of the original table. The 16mm thick piece of MDF in the centre of the two tables is about 1.8m by 900mm and was created some time ago, nearly two years in fact, when I first thought up the idea for the film. As can be seen from the photos, the horizon and rolling hills are placed as far into the background as possible, in front of the sky cyclorama, but not close enough to cause unwanted shadows on the blue. Because I had envisioned a launch ramp facility to rise up from its underground hangar, the launch area itself, the light grey section, is positioned between the two larger tables, with just enough room for a model mover to crawl underneath and operate the sliding doors to the underground hangar. The front table, nearest to the camera, has a sheet of 2mm styrene sheet firmly attached to the leading table to facilitate the lowering of the camera to the apparent “ground level”. Total length and width – 4.5m in depth and nearly 3m in length – a very small set, but reasonably effective in conveying far greater distances through the use of varying scales of vehicles and buildings as these photos show. Toy cars have been collected for a number of years – Matchbox/Hotwheels sizes for the foreground and midground, “N” gauge scale (1/144) for the background areas. Scratchbuilt or converted vehicles are generally 1/72 or 1/35 in scale, although I do plan to use larger ones for the foreground in future photographs. Here are a number of shots taken on this particular set, as well as others taken on a slightly smaller set, minus the light grey launch area section, to illustrate the effectiveness of forced perspective photography.

    1. Thanks Richard. Glad you enjoyed the article. I'll have to write Part 2 soon. Check out a film from the 1990s(?) called "Attack of the 50 Foot Woman", with Daryl Hannah and Alec(?) Baldwin - absolutely stunning forced perspective setups. I think "Cinefex" magazine did an article on the FX for the film. Worth checking out. Thanks again.
      Cheers
