In order for a, b and c to form a triangle, two conditions must be satisfied. First, all side lengths must be positive: Second, the sum of any two side lengths must be greater than the third side length: Write a program to read in three real values and use a function for testing the conditions and another function for computing the area.
Each of the three aspects of the triangle relate to light and how it enters and interacts with the camera. The three elements are: Most importantly — a change in one of the elements will impact the others. This means that you can never really isolate just one of the elements alone but always need to have the others in the back of your mind.
Many people describe the relationship between ISO, Aperture and Shutter Speed using different metaphors to help us get our heads around it. Let me share three. A quick word of warning first though — like most metaphors — these are far from perfect and are just for illustrative purposes: The Window Imagine your camera is like a window with shutters that open and close.
Aperture is the size of the window. Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more that comes in. There are a number of ways of increasing the amount of light in the room or at least how much it seems that there is.
You could increase the time that the shutters are open decrease shutter speedyou could increase the size of the window increase aperture or you could take off your sunglasses make the ISO larger.
Sunbaking Another way that a friend recently shared with me is to think about digital camera exposure as being like getting a sun tan. Now getting a suntan is something I always wanted growing up — but unfortunately being very fair skinned it was something that I never really achieved.
All I did was get burnt when I went out into the sun. In a sense your skin type is like an ISO rating. Some people are more sensitive to the sun than others.
Shutter speed in this metaphor is like the length of time you spend out in the sun. The longer you spend in the sun the increased chances of you getting a tan of course spending too long in the sun can mean being over exposed.
Aperture is like sunscreen which you apply to your skin. Bringing It All Together Mastering the art of exposure is something that takes a lot of practice.
Keep in mind that changing each element not only impacts the exposure of the image but each one also has an impact upon other aspects of it ie changing aperture changes depth of field, changing ISO changes the graininess of a shot and changing shutter speed impacts how motion is captured.
The great thing about digital cameras is that they are the ideal testing bed for learning about exposure. You can take as many shots as you like at no cost and they not only allow you to shoot in Auto mode and Manual mode — but also generally have semi-automatic modes like aperture priority and shutter priority modes which allow you to make decisions about one or two elements of the triangle and let the camera handle the other elements.
