Architectural Photography

In 1970, my dad gave a lecture on Architectural Photography. We don't know where or why. We know he was involved in Montréal photo clubs at the time and was making a few extra dollars on the side with his photography, so he may have given a lecture at a club meeting. We also know that he went to Charlottetown in the winter of 1970, although no one in the family knows exactly why. It may have been work-related, or he may have been looking for work. The family wanted to moved from Montréal and we know he went on job-scouting expeditions to Calgary and Victoria later in 1970. Perhaps he spoke to a camera club in one of these cities. 
Anyway, at some point he gave this lecture. Or, at least wrote it up. 
I've given his lecture a quick edit. Apparently, there was a great comma shortage in 1970, and Dad was willing to sacrifice their use. But this is pretty much as he wrote it. 
Dad makes reference to a bridge photo. We don't know which photo he intended to use, but a good bet is the one I've included: a 1962 photo of the Jacques Cartier Bridge in Montréal. It certainly fits the period, location and subject matter. And it's a darn fine photo.
He makes further reference to a diagram. Sadly, that is lost to the sands of history.

ARCHITECTURAL PHOTOGRAPHY

Before discussing this subject, let’s look at architecture to see what it is.  To me, architecture is the art of producing a building on paper and the science of building. Buildings have interiors and exteriors. Interiors have various components such as wall finishes, floor covering, ornaments, etc.  Architectural photography is the science of producing an image on paper of the physical result of the science of building.

The usual three basic requirements are needed to produce a picture of a building, namely – (1) Light - artificial or natural, (2) Camera and (3) film. I will come back to this later on.

Architectural photography can be frustrating, hard work and annoying. An example of frustration was a job I had to do which required a visit early in the morning to get the illumination on the right facade. One Saturday morning, bright and early, I left home for this location, the sun shining brightly only to arrive at the scene to have a cloudy dense sky. For three more weeks this happened. It was four weeks later that I managed to get this picture. This points out one very important factor required in this type of photography - PATIENCE - if you don't have lots of it, forget architectural photography.

I remember I had a building to photograph on the South Shore. Again off I go bright and early. This building was in an open area and I had lots of room. Having set up my equipment, I started to survey the scene, getting my locations picked I took my first photo when a car pulled up behind me, I didn't pay much attention and proceeded to another spot for a second picture only to be stopped by the police. If you don't think being followed by police while trying to concentrate on taking pictures isn't annoying then I don't know what is.

Persons interested in architectural photography should carry more equipment other than photographic equipment. Two of the most useful  items are a flashlight and a magnifying glass. I always carry these when I try this type of photography as they are very useful as will be seen later. Another useful item is a good level. The slightest off-level position of the camera back may show up in the final print as a small distortion of a line especially when a wide angle is used.

In architectural photography the photographer has specific problems of approach namely:  

  1.   Three dimensional aspects.  

  2.   Lighting          

  3.   Rendering of substance.  

  4.   Architectural aspect.  

  5.   Environment of subject.  

1. The Three Dimensional Aspect:

A building is a design of volume, solid forms of simple or intricate structure. The volume must then be preserved in the photograph except for flat elevations. The illusion of -volume implies perspective and scale ,·which the photographer controls by selecting the point of view, scope of lens image to size of negative. Perspective is controlled by the distance of the lens from the subject regardless of the focal length or size of negative. However, normal association of objects gives a more literal impression of scale and perspective.

(NOTE: Pass out bridge photo at this point).

Angle shots may be used but only with great taste and discrimination. The only natural source of illumination I know of is the sun, and there are many variations of sunlight, some useful and some of it of no use as far as architectural photography is concerned. To make full use of them, the photographer must know what he wants to do before he does it. In general, never take an exterior shot with the sun directly overhead or on a very cloudy day when there is little or no shadow. Generally, the best time for architectural photography of exteriors is either early in the morning or late afternoon when the sun casts long shadows. This tends to give the subject depth and third dimension quality.

2. Lighting:

Good architectural design incorporates the factor of illumination, natural or artificial and the photographer must respect this at all times. As the photographer cannot move the sun, he should study the problem, determine the most favourable light and proceed accordingly. The photographer can more easily control his lighting on interiors but he must not impose a false quality, quantity or direction of light. Remember the elements of architectural photography are light and shade, walls and space.

3. Rendering of Substance:

If a wall is plaster or brick, a table of polished hardwood, a floor of stone etc. the photographer must convey these facts without confusion. The rendering of textures, tonal values are of great importance throughout. It is possible to subdue or exaggerate but we must no omit the impression of recognizable materials and surfaces.

4. Relationship to Architect:

Photographing for ourselves we have no obligation except to ourselves but if photographing for a builder or architect, his requirements must be considered. We must consider his concept of his work, his design of subject and record what it is.

5. Environment:

This presents quite a problem and that is in the control of objects unrelated to the principal subject.  Few building exist in detached simplicity of plans and renderings, for there are trees, wires, poles, moving objects, etc. As only a few of these items can be removed, the photographer must select the most favourable point of view and use the elements in the scene in the structure of his composition. If their appearance is detrimental to the picture another viewpoint must be sought. If this cannot be done, the only other solution is to remove them from the negative. This is an absolute last resort. It must be remembered whatever is included in the photograph must have importance. (NOTE: Relate to bridge picture).

Cameras:

Architectural photography is best accomplished using a camera having certain movements which will be mentioned later on. Small hand-held cameras without adjustments are not recommended for this type of work. Let’s take a look at photographing a tall building with a ordinary camera.

In order to photograph a tall building with an ordinary camera the camera has to be tilted. This produces a print of a building falling backwards, in other words the vertical lines converge at the top producing an unnatural image (Show diagram). The reason for this is due to the fact that the top of the building is further from the camera than the bottom, which means the top of the building is smaller than the bottom. This can be avoided by keeping the camera  horizontal , which means the film plane must be kept parallel to the building. This eliminates converging lines but part of the building is lost (Show Diagram). This can be avoided if we have space enough to move far enough away to get all, the building in, but at most times this is impossible, and may also lead to an undesirably small image on the negative.

Architectural photography is best accomplished using a camera having a sliding lens panel. This is a lens board having a rising front with a horizontal movement. The function of these movements is to permit the image to be centered on the film without tilting the camera. The rising front is an indispensable movement in this type of photography. If a photograph is taken looking down from a high point, the falling front movement can be used to prevent diverging verticals.

A further development in this type of camera was the addition of a swinging and tilting back. This permits (1) control of parallel or converging lines of the image, which means they control the shape of the image - (2) Again this type of back can be used to control the region of sharp focus of an object in depth over the entire negative. One interesting point is that centering of the image is not usually seriously affected by the back.

As with the movements provided by the sliding front, the movement of the back tilting in particular is especially valuable in architectural work. The tilting back may be used to provide in effect an additional rising front, for when the rising front movement does not provide sufficient for a given subject, the camera may be tilted upward and the back tilted forward  to bring the film into vertical plane. This permits you to break the rule which says that the camera must never be tilted.

Again, these fronts and backs can be used to create distortion for whatever purpose is needed. Just one note here, that when the swing or tilt back is used, both the shape and the focus of the image are affected together. It must be remembered that all camera adjustments have little meaning unless the camera is first set up in the ideal position which is level in both horizontal and vertical directions with the axis of the lens centered on the negative and all adjustments set at zero.

Wide Angle Lens:

These should be restricted in use as far as possible, and should be used for work under cramped positions or to emphasize certain aspects such as when wanting to create a false impression as to make a small room seem lofty, long lines, high buildings etc.

FILMS:

Because of the contrast in this type of work a film must have considerable foot to its character and because of textures must have good separation qualities. Panatomic-X and Ansco Versapan are good films for this type of work.

NEGATIVE DEVELOPMENT:

This is a most important phase as good architectural work implies the recording of accurate values of tone and texture. It is important that strong highlights are not blocked up and that shadow detail be retained. A good architectural photograph will be best revealed by a fine brilliant print which must come from the negative.

Architectural Interiors:

This type of photography requires considerable care and a camera which permits arrangement of the picture and focusing on a ground glass. Many interiors require the use of a wide-angle lens to include as much of the subject as possible; however, if it can be done with another lens, avoid the wide angle as much as possible because of the distortion of the foreground being prominent and pillars or columns in the margin of the picture spreading in width and becoming ovals. A lot of this can be avoided by camera position.

One good example is in churches. Having the camera to one side of the nave or transept will bring one of two rows nearer to the middle of the picture, and the other row of columns will be shown one behind the other and as counterparts of the columns on the other side. A central point in a church having columns is the worst position.

In small interiors avoid the presence of having furniture at the edges of the picture especially the corners. Keep the foreground free from prominent objects because these would tend to dwarf other objects or parts of the subject.

Again, if at all possible, avoid the wide angle lens, but if used, try to place the camera so that as much as possible of the subject is flat to the lens.

Sunshine may often be used with good effect on interiors, but best results can be obtained when the outside lighting is from a lightly clouded sky. This means the brightness range is within the capacity of the film emulsion. In small interiors where there are deep shadows use a flash bulb a few yards from these areas keeping the flash out of the field of view.

In focusing an interior subject on ground glass always focus wide open and then stop down for maximum depth of field sharpness. As a rule a magnifier is always necessary for examining the ground glass image in dim light to check focus. Another useful item for this purpose is to carry a small flashlight.

One problem with photographing interiors is Halation, therefore use backed films. In large interiors avoid sunlit 1vindows as much as possible to help prevent this problem. Exposure for interiors can be from a few seconds to hours because of the differences in illumination levels. However, always be overexposed rather than- underexposed.

Filters:

One important feature of architectural exterior photography is controlling the sky. Most exterior subjects require a medium yellow. This will make for some separation between the building and the sky and will be much better than not using a filter.

However, it must be remembered that if there is no blue sky the filter will have little effect. If the building is white or light coloured, we use a darker filter such as a yellow orange to darken the sky and show the building more. A deep yellow or yellow-orange filter will lighten yellow or red brick buildings and enable texture to show up more clearly. However, be careful for danger of lightening brick too much. If there is this possibility, use a polarizing to darken sky only.

Certain types of architectural photography require a polarizing filter particularly when reflections tend to obscure details of roofs, walls and windows. In photographing floors, generally the use of a polarizing filter will permit the grain of the wood and pattern of the floor to show much better than without a filter. Should no polarizer be available, use a medium yellow for light floors such as oak and yellow-orange or light red for darker floors.

An interior, by daylight, to give normal correction a medium yellow filter should be used. Under artificial light a light yellow may be used or even dispensed with if any rugs or furniture are prominent in the picture.

An interior containing upholstered furniture of different kinds of wood is very difficult to give normal rendering to, but a yellow-orange will do a reasonable job. In some cases that are extremely fussy, find the filter to match the type of wood which is most predominant.

As far as woods are concerned, the following  would be recommended:

-- For walnut or mahogany a medium-red filter will render beautiful grain and minimize scratches.

-- On dark mahogany use a deep red filter,

-- on satinwood or oak the use of a yellow-orange is a must to render the grain correctly

-- a medium red will do a nice job on the grain of rosewood.

In photographing interiors the choice of filters is very important to subdue certain colours and bring out certain colours - which means - certain colours being rendered in tones to similar, or having the colours blending with the background. Experiment by looking at the scene through a viewing filter to determine whether or not one of the correction type or contrast type of filters is required.

A correction filter for red sensitive panchromatic film: (1) Medium yellow in daylight. (2) Medium green in artificial light.

A contrast filter for red sensitive panchromatic film: (1) Yellow-orange in daylight. (2) Medium red in artificial light.

Tips on Technique:

(1) Generally, the best time for architectural photography is either early morning or late afternoon vmen the sun casts long shadows. This tends to give the subject depth and third dimensional quality.

(2) Stop down lens as far as possible.

(3) Unless angle shot is required, keep camera level to keep lines vertical and maintain true perspective.

Photographs of architecture are rarely worth looking at when the aim has been only to get a picture of a building.

Bee Careful

Dad did love to take insect shots. Here, he's captured a great image of a bee.

Wall

Yes, it's a wall. But check out all those cool old cars!

Plane

Don't know what's going on with this picture....except it's, you know, a plane.

Then and Now: Christmas at The Ledge

There are few things that liven up the holidays more than seeing the The Legislature building in Victoria lit up in Christmas colours. Dad took this shot in 1974.

Here's a Christmas shot of The Ledge I took in 2012.

Tracks

Don't know where, can't say when. It's a mystery.
 

Expo 67 - Closed

50 years ago today, Expo 67 closed. The site continued on for a few more years as the Man and His World exhibition, but by the mid-seventies portions of the site were falling into ruin and were being dismantled.

The  American pavilion is one of the few structures left, but it almost didn't survive. In 1976, it was almost destroyed by fire. Today, it's now known as the Montreal Biosphere, and has been turned into an environmental museum. I visited the Expo site in 1979. Here's my two shots of the burnt-out buckyball, before it was repaired.
In late 1978 or early 1979, a small second unit crew went to Montréal and filmed some scenes for the episode "Greetings From Earth" of the original Battlestar Galactica series. While many of the scenes were just establishing shots of a decayed futuristic landscape, series star Dirk Benedict and guest star Bobby Van did travel to Montréal to film a couple of scenes near the ruins of various pavilions. You can see the Man the Provider Pavilion in the background of this scene. By the time of my visit in 1979, Île Notre Dame was closed, and we could see the pavilions across the river being dismantled. I took two last pictures....

Expo 67 - Dad

Dad didn't take all the family pictures at Expo 67. Here's a shot of him on the site probably taken by mom.

Expo 67 - American Pavilion

The iconic American Pavilion, Buckminster Fuller's geodesic dome. Or a Buckyball, if you prefer. This seems to be the only picture dad took of it.

Expo 67 - La Ronde 5

I might be cheating a bit here. These undated photos are the only colour photos of me that Dad took on the Expo grounds -- the La Ronde amusement park area, to be precise -- but I'm wondering if they really were taken during 1967. The grounds and pavilions at Expo 67 continued for a number of years after 1967 as an exhibition entitled Man and His World. I seem to be a year or two older than in the other Expo pictures I've found, so I suspect that these are technically not Expo 67 pictures, but perhaps taken in 1968 or 1969. Of course, the clincher is the hats -- the Montréal Expos didn't start playing until 1969. The franchise was not even awarded until 1968, so this picture must be from 1969, maybe even 1970. Interestingly, these were the only Expo (or Man and His World) pictures on the roll of film. My Dad took his camera, with colour(!) film in it on this particular trip, all the way to the Expo site and only took these two shots.
