Terms – Exposure 2

So what is the difference in exposure between photography fields? The answer may be more fascinating than you realize.

Without an in-depth knowledge of a science it seems basic and small. Thus it would seem incapable of containing enough product for very many markets. However they more the science is studied and further discoveries are taken the science’s markets begin exploding with possibilities. Within each market is a specialized way of dealing with the product for that market. Allow me to explain:

A coin to the founder is equal to his time, resources and product used in minting it. To a collector (still in the market of the numismatist) this coin no longer holds only the value of the coin upon its date of minting, but now any more historical and geographical significance, making its value increase (besides the rising value of precious metals).

To photograph such an item as marketed to a collector, he will be interested in seeing the coin’s condition, its inscriptions, distinguishing marks and a clear representation of the metal color. This suggests to the photographer a specific method of lighting, absence of artistic embellishment and being close up for the best view of the coin’s condition. Can we safely say this requires skill and vocational specialization? Yes, without a doubt.

Take the same coin but in a different market. This coin is not being photographed to a market focus on collectors but sold to a precious metals store who pays out cash to the seller. Photography in this market (if used) would most probably focus on damage detail, over-all likeness and any metallic tarnishing. While these shots are close enough in description, the execution and lighting set-up of the shots are quite different.

While the subject is lit just as well in both shots, the lighting is different because of the market’s push for equal, over or under exposure of the background in reference to the subject. The details of how this is accomplished is still a new topic of discussion.

Portraits – Soft light

Softening light is a process in which light is made to evenly fill the viewing area. This can be done in many ways but often the simplest methods are the best. Soft-light is not only about adding light, it also involves making sure that the natural light in your shot is not too concentrated in one place.

Basics: When lighting a surface it is important to light the surface evenly to prevent overlapping coverage. Light is a key element to showing the rise and fall of a surface. So as you can imagine, if a person’s face has areas of their face better lit than others it can give them a very strange appearance.

Softening the light can be done basically two ways by either diffusing the light or reflecting it. Diffusing the light uses a direct light on the subject with a partly transparent piece of material between it and your subject. Lighting companies sell “soft boxes” which fit over the light making it easier to soften the light than holding a diffuser in-front of it for every shot.

Reflecting the light is indirectly lighting your subject by bouncing the light coming from your light source (sun, porch light, strobe, flash, etc) directly on your subject. Indirect or reflected light will not be as “harsh” as it would be from the light source but can still be too harsh if physically placed too close to your subject. So use distance (close or far) to your advantage here as well!

Listed below are some examples of diffusers and reflectors. Have fun and use your imagination! This is the stuff of artistic shooting!

Diffuser:

• Umbrella (Great for artistic element in a shot too!)
• Translucent fabric (not darkening fabric)
• Plexiglas (colored Plexiglas)

Reflector:

• Water
• Disk (sold at any videography and photography lighting store)
• Fill card (Light or dark-colored – darker colors absorbing more light)
