Is it actually paranoia if they really are out to get you?
The Illuminati, that shadowy secret society that is said to control the world, may have been behind the invention of modern photography. After all, the pyramid, a symbol that is often associated with the Illuminati can, from the right angle, look like a triangle.
Because the triangle is often used to represent the three elements of photography: light, time, and aperture, maybe the Illuminati really did invent photography?
Or, maybe they simply saw the potential of a future technology to control people's minds and manipulate society? Only time will tell.
Personally, I believe this notion is just click bait because I needed a catchy title and intro for this article.
Light Drawing – phos graphe!
Back in 1839 Sir John Herschel needed a word to describe a new process of capturing images using photosensitive surfaces / chemicals. Hence the word photography. While the vast majority of photographs taken today are imaged on electronic sensors and converted to digital images by computational devices, the 3 basic elements of exposure have not changed. These elements are:
Sensitivity of the surface / sensor (ISO)
The time light has to expose the photosensitive surface (shutter speed)
The aperture / opening of the lens that’s funneling light to the sensor (F-stop)
A Love Light (Exposure) Triangle
These three elements are often described using the concept of a triangle. The exposure triangle to be exact. It is a very popular way to show the interplay between ISO, Time and Aperture. For me the concept is easier to present using a pie chart because the interplay becomes immediately obvious.
In any given situation we have a quantity of light. Consider a properly exposed image as having 100% of the light the sensor needs to create the effect we want. If we look at this as a pie chart it might look something like this, A perfect blend of our 3 elements.
It’s hard for me to imagine such a scenario and technically it makes no sense at all. But, as a metaphor for understanding exposure it’s pretty cool.
Let’s say you are shooting in the evening and have much less light to work with. If you are hand holding the camera, or if the subject is likely to move, you need to keep the amount of time the shutter is open as short as possible to achieve your desired effect.
How do you do this while making sure you have enough light to achieve the desired exposure? You have to:
a) open the aperture wider,
b) or, push the sensitivity of the sensor by increasing the ISO.
c) or, a little of both. The new relationship between might look something like the left image where both ISO and aperture size have increased.
Perhaps you need to maintain the aperture size for artistic effect. In that case you would get a relationship like the one shown in the second graph. In the second example, the ISO is dominant contributing factor.
Finally, maybe the aperture doesn’t matter for artistic reasons. In that case you might open the aperture to its widest possible setting (f1.2, 2.8, or whatever). Now, you would have a relationship like the one shown in the bottom left graph.
Obviously, the actual percentages of importance for each of the elements are nonsense. The purpose of the charts is to show how the 3 elements of exposure interact to obtain desired exposure.
But wait there’s more!
This is the first of a series of articles I am putting together on photography and the lessons I have learned that have enabled me to quickly adapt to existing conditions while maintaining my particular artistic intent.
