Three Basics Elements of Photography
Today, modern DSLR cameras come with many features some of which are accessible via a complex menu system. While all these features are designed to enhance the camera’s functionality, when it comes to photography, three basic elements apply.
This refers to the amount of time a camera allows light to come in and stay exposed. As you already know, to capture a photo, a camera’s sensor must be exposed to light for a certain period of time. For this to be possible, camera’s are fitted with a “door” which allows in light into a light-proof box. This is where the sensor is located.
In this case, shutter speed is the duration the shutter remains open which means the longer it does, the more light is allowed in.
For instance, if the shutter remains open for 2 or 3 seconds, twice or thrice the amount of light is allowed in. Modern DSLR cameras have a huge range of shutter speeds for photographers to work with. This enables photographers to take short or long exposures which are perfect for landscapes or light photo sessions.
Shutter speeds can also help photographers achieve motion blur. This can be done by panning the camera and following the subject.
Just like shutter speed, Aperture is a common setting on modern DSLR and one of the most important photography skills. Basically, it is a setting that controls the size of the shutter which allows light to come in via the lens. For this to happen, the aperture blades change. When the size is smaller, less light is allowed and when the size is larger, more light is allowed.
What you need to know is that aperture is measured in f stops. That is f/2.0 or f/4.0. If the value of the f-stop is small, it means the opening is larger. This translates to more light and also explains why lenses with lower f-stops are usually expensive.
What you need to know is that aperture changes how the final photo looks like. It also controls focus – in front and behind the image you are focusing on.
For instance, if your focus is on a person or statue, you may identify other objects in the background. For instance buildings, trees, other people, cars and others.
If you choose to capture the image using the lens with the smallest aperture, objects in the background will appear sharp in focus. Alternatively, you may choose to take the photo using a lens with the largest aperture, the objects in the background will appear out of focus.
Modern DSLR cameras are designed with an ISO setting of 100 but the value can be adjusted from 100 to 6400 to 25600 or higher. By making such adjustments, you give the camera the ability to capture photos in low light.
When you choose a higher ISO setting, your photo is captured but background noise from the camera’s electronics will leave the image looking grainy with a low detail resolution. This problem is called digital noise.
To prevent such problems, you have to combine the three elements as mentioned above. For instance, smaller f-stop value for aperture, a lower value for ISO and higher value for shutter speed (1/1000) results in a sharper image with no blur and very little digital noise.
