Outdor lighting

As a photographer, you work with light to produce quality pictures. The color, direction, quantity, and quality of the light you use determines how your subjects appear. In the studio, with artificial light sources, you can precisely control these four effects; however, most of the pictures you make are taken outdoors.

Daylight and sunlight are not a constant source, because they change hourly and with the weather, season, location, and latitude. This changing daylight can alter the apparent shapes, colors, tones, and forms of a scene.

The color of sunlight changes most rapidly at the extreme ends of the day. Strong color changes also occur during storms, haze, or mist and on blue wintery days. The direction of light changes as the sun moves across the sky. The shape and direction of shadows are altered, and the different directions of sunlight greatly affect the appearance of a scene.

The quality of sunlight depends on its strength and direction. Strong, direct sunlight is “hard” because it produces dark, well-defined shadows and brilliant highlights, with strong modeling of form. Sunlight is hardest on clear summer days at noon. Strong sunlight makes strong colors more brilliant, but weak colors pale. Sunlight is diffused by haze, mist, and pollution in the air.

This diffused or reflected light is softer; it produces weak, soft shadows and dull highlights. Directionless, diffused sunlight is often called “flat” lighting because it produces fine detail but subdues or flattens form. Weak, directionless sunlight provides vibrant, well-saturated colors.

Frontlighting

The old adage about keeping the sun at your back is a good place to continue our discussion of outdoor lighting. The type of lighting created when the sun is in back of the photographer is called frontlighting.

This over-the-shoulder lighting was probably the first photographic advice you ever received. This may seem to be a universal recipe for good photography. But it is not. The case against over-the-shoulder lighting is it produces a flattened effect, doing nothing to bring out detail or provide an impression of depth.

The human eye sees in three dimensions and can compensate for poor lighting. A photograph is only two-dimensional; therefore, to give an impression of form, depth, and texture to the subject, you should ideally have the light come from the side or at least at an angle.

Side Lighting

As you gain experience with various types of outdoor lighting, you discover that interesting effects can be achieved by changing the angle of the light falling on your subject. As you turn your subject, change the camera viewpoint, or wait for the sun to move, the light falls more on one side, and more shadows are cast on the opposite side of the subject. For pictures in which rendering texture is important, side lighting is ideal.

Side lighting is particularly important with black-and- white photography that relies on gray tones, rather than color, to record the subject. Shadows caused by side lighting reveal details that can create striking pictures from ordinary objects that are otherwise hardly worth photographing in black and white.

Anything that has a noticeable texture-like the ripples of sand on a beach, for example-gains impact when lit from the side. Landscapes, buildings, people, all look better when sidelighted.

This applies to color photography as well. Color gives the viewer extra information about the subject that may make up for a lack of texture in frontlighting, but often the result is much better when lit from the side.

Pictures made with side lighting usually have harsh shadows and are contrasty. To lighten the shadows and reduce the contrast, you may want to use some type of reflector to direct additional skylight into the shadow areas or use fill-in flash, whichever is more convenient.

Backlighting

When the sun is in front of the photographer, coming directly at the camera, you have what is referred to as backlighting; that is, the subject is backlit. This type of lighting can be very effective for pictures of people outdoors in bright sunlight. In bright sunlight, when subjects are front-lighted or even sidelighted, they may be uncomfortable and squint their eyes.

Backlighting helps to eliminate this problem. Backlighting may also require the use of a reflector or fill-in flash to brighten up the dark shadows and improve subject detail. Backlighting is also used to produce a silhouette effect.

When you use backlighting, avoid having the sun rays fall directly on the lens (except for special effects). A lens hood or some other means of shading the lens should be used to prevent lens flare.

The use of light in a photograph can be the deciding factor of whether that picture will be spectacular or terrible.

When you use your camera to automatically chose aperture and shutter speed, what your camera is actually doing is using the built in light meter and measuring how much light is being reflected to the camera.

But that doesn’t mean that’s all there is to it. You should also think about the angle of the light entering the frame, what kind of shadows you want, and whether you want to use fill-in-flash (using flash to light the subject if you have a really bright background).

If you are shooting at night you can create all sorts of cool effects like lights in motion, pictures with moonlight, or silhouettes like the one shown here. The following are just some examples of all the possibilities.

The angle of light should be taken into careful consideration whenever you feel like you want to create a specific effect. Shadows can be very powerful when cast over half of someone’s face. In this photo on the left the light is striking the statue’s face from the rear right of the camera and this adds more depth to the picture. It also adds more coloring because if front-lighting was used his face would likely be over exposed, and if back-lighting was used his face would just be black like a silhouette.

The effect of rays of light indoors and outdoors. can be very spectacular. A brilliant part of some great photographs is the ability to see actual rays of light. Whether it be in the setting of a brilliant sunset, light pouring through a window or from artificial lights it can look very impressive. Usually the only way to obtain something like this is a narrow aperture (high f/stop) and a very slow shutter speed.

Silhouettes are another interesting example of using light. The way to create a silhouette is to have significantly brighter light coming from behind the subject. In doing this it is important to take your camera light reading off of the background instead of the subject in order for the camera to adjust for an exposure based on the backlight..

If you keep experimenting with different ways of using light you will find that you can get very interesting results.

History of the first Polaroid color photography

Edwin Herbert Land (1909-1991), ForMemRS, FRPS, Hon.MRI was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation.

The Polaroid Land camera is an was produced between 1947 and 1983 and is a self-developing type camera. Polaroid Land Camera Model 95 was the first to be commercially available. It produced prints in about 1 minute. It was first available to the public in 1948.

Land’s new approach was to get the dyes in the film to move from the negative to the positive by way of a reagent by employing diffusion transfer to. A negative sheet inside the camera itself was exposed, then it was lined up with a positive sheet and squeezed through rollers which spread a reagent in between the two layers, creating what could be called a developing film sandwich of sorts. The negative developed quickly and after a minute, the back of the camera could be opened so the negative could be peeled away. What was left was the actual print (picture).

In 1963, the Polacolor pack film was introduced by Land, and this made it possible to take instant color pictures. The process involved was pulling two tabs from the camera, the second of which pulled the “film sandwich” through the rollers to create the picture. Since the camera was now dealing in color, the process was much more difficult, including a film negative which contains 3 layers of emulsion that are sensitive to blue, green, and red. 

Dye developing molecules lived under each layer in their complementary colours of yellow, magenta, and cyan. When an emulsion layer is struck by light, the complementary dye below it is blocked. For instance, when the blue sensitive emulsion layer is struck by blue, the yellow dye is blocked, but allows the magenta and cyan dyes to transfer to the positive, which then combine with each other to create blue. When green and red (yellow) strikes their respective layers, it blocks the complementary dyes of magenta and cyan below them, and only the yellow dye is allowed to strike the positive.

In 1972, Land introduced integral film, which didn’t require the photographer to peel apart the positive/negative to reveal the photograph. This process was like Polacolor film with a bit more timing and layers involved. The film itself integrates all the necessary layers and functionality into the film pack itself. The SX-70 camera was the first camera to use this type of film.
