Photographing buildings under diffuse and non-frontal lighting conditions
The purpose of this assignment is to photograph four buildings while the sun is located either to the side or to the rear of the buildings. They are the MBNA Career Center, Eisenhower Parking Garage, Steidle Building, and the north addition to Sackett Building.
The primary technical consideration is measuring the exposure properly so that the details of the facades are clear, the color balance is realistic, and undesirable effects such as excessive contrast and lens flare are avoided.
In addition, in this assignment, you can gain further experience (1) avoiding converging vertical lines, (2) becoming aware of other aspects of perspective such as the camera-to-subject distance and the height of the camera relative to the subject, (3) achieving aesthetic composition by selection of the vantage point on-site and by editing the images, and (4) either adjusting color balance in color photographs or adjusting contrast in black-and-white photos.
On-site considerations
To photograph all of these buildings, select a day on which the weather is either sunny or partly cloudy. and select a time of day before 3 PM. Do not take the photographs, when the sky is overcast. In addition, for each building view specified below, you should record a variety of pictures, each from somewhat different vantage points. Afterwards, out of several views, you can select the best view for each case, which you will subsequently enlarge and edit.
For the MBNA Career Center and for Steidle Building, select a vantage point such that you are viewing the building from an oblique angle. Specifically, you will be looking at the northwest façade and northeast-facing side of the building. Your back will face roughly northward. Record an oblique view of the MBNA Career Center that has two-point parallel perspective, i. e., the film plane make approximately a 45° -angle with the wall of the building. Record an oblique view of Steidle building that has two-point perspective, in which the film plane makes a small angle with the façade of the building. For the 35-mm format, a lens with a focal length of 28-mm or less will provide a sufficient angle-of-view, so that part of the façade is not cut off in the photograph.
For the Eisenhower Parking Deck, select a vantage point where you are viewing the northwest corner of the building. Record an oblique view of the building that has two-point parallel perspective, i. e., the film plane makes approximately a 45° -angle with the wall of the building. You should take advantage of the nearby, small ridge. By using it to elevate the camera, you can improve the perspective reducing distortions that arise from the height of the building.
For the north addition to Sackett Building, select a vantage point, where you are looking southward. From two different camera-to-subject distances, record an oblique view of the building that has two-point perspective, in which the film plane lies almost parallel to the stone, northward-facing wall of the building. In this view, you can see the eastward facing wall, which consists of pink aluminum panels. To select the first camera-to-subject distance, stand as close as possible to the building without cutting off part of the eastward-facing wall in the picture and without causing the vertical lines to begin to converge in the picture. You may find that, by using the vertical format, you can stand closer to the building and meet these conditions. To select the second camera-to-subject distance, stand about two or three times the distance that you used for the first photograph.
Some additional technical considerations are the following.
For this assignment, the choice of color or black-and-white is open. If you are using film, you should use a slow film speed, e. g., ISO 100. If you are using a digital camera, you should select the slowest "film speed."
For this assignment, the quality of your results will depend strongly on accurately measuring the exposure. You may need to review the lecture on measuring exposure and the Reading Assignment, "Determining Exposure." Additionally I encourage you to discuss any questions with me.
You should crop the original photographs appropriately to remove excessive amounts of foreground and extraneous information.
If you record the images using a 35-mm SLR, make sure that the final photographs do not show excessive graininess.
If you record photographs in color, make sure that the color balance is aesthetically acceptible.
If you record the images using a digital camera or if you scan conventional photographs to produce a final digital image, make sure that the final photographs do not show the effects of degraded sharpness that the lack of resolution, i. e., the lack of pixels, can cause.
If you record the images using a digital camera or a 35-mm SLR, make sure that the final photographs do not show degradation of image sharpness caused by poor optics or poor focus.
One approach to reduce costs associated with completing the assignment is to request from the photofinisher "Develop Only" service and to specify that the negative should not be cut into short strips. (This service is relatively inexpensive.) Then you can use a negative scanner to make high-resolution digital images from each frame. You can view the (reversed) images and edit them without incurring any costs. Then you can print the final versions onto photographic-quality paper using a high-quality ink-jet printer. For this approach to be effective, you must obtain negative scans at very high resolution, typically 4000 dpi. A good practice is to use compressed gas to blow dust off of the negatives before scanning them. This practice reduces the tedious task of removing dust spots from the final image.
To complete the assignment, submit five nominally 8- x 10-inch or 8- x 12-inch enlargements that correspond to the aforementioned buildings. If the final photographs are digital representations, print them onto photograph-quality paper using a high-quality ink-jet printer.
With the photographs, submit a brief statement in which you present the technical details.
Make and model of camera and lens.
Recording medium either film and film speed or CCD resolution in pixels.
Approximate time of day when you recorded the photographs
