Understanding Your Camera's Exposure Settings

The process of removing yourself from the dependence on automatic settings isn’t as difficult as it may initially seem. The most important thing to do to begin an understanding of how to create better photos in the manual setting is to know how to control the settings for exposure in your camera. When you understand how shutter speed, aperture, and ISO settings interact, then you’ll well soon be able to shoot all the time using manual modes.

Shutter Speed

The shutter speed you set on your camera determines the amount of detail that you’re capable of recording in a single image. The shutter speed ranges between 30 seconds and fractions of seconds up to 1000th of a sec. It is essential to use a high shutter speed when you are taking photos of moving objects like race cars or aircraft. A photograph taken at 1/2500th of a second will clearly capture the rotor of a helicopter in mid-flight. You can, however, take the identical helicopter at a slower speed, say 1/250th of a second, and all you’ll get is a blur. A lot of SLR cameras come with an additional setting called “bulb,” which is identified by the word “B” when you select the shutter speed. Bulb mode allows photographers to open the shutter as long as the shutter release lever is held (unless the batteries go out first). This mode allows photographers to utilize shutter release remotes or cables to take long exposures, like star trails or streaks of light from cars that pass by.

The shutter speed is not just what affects the clarity of moving objects. However, it can also have an effect on the amount of light that is exposed. When the shutter speed increases, it is the quantity of light allowed to pass through the sensor or film is diminished. In times of greater lighting, this typically causes no problem for photographers. As the amount of light is reduced, the duration required to properly expose the image is increased. In most cases, a flash will compensate by increasing the amount of light, while the strobe mimics an abrupt stop in the motion. Naturally, as we’re working in manual mode, there are several options open to us, including altering the aperture or in the ISO setting.


The aperture setting of an SLR camera controls how much light is allowed into the camera. Technically speaking, the aperture settings of film cameras and aperture settings of digital cameras function in the same way. However, there are a few variations. The aperture setting on film cameras is an actual device that functions in a similar way to how an iris regulates how much light is allowed to enter the eye. When the aperture (or the iris) is open and more light is permitted to pass through the lens’s back (pupil) and hit the camera (optic nerve). But the digital camera does not possess a physical device that functions in this way; however, the aperture’s settings can be controlled by a combination of features of the lens and the camera’s capability to process light.

These apertures are identified with numbers that represent the amount of light that enters a camera. These numbers are also referred to by the name “f-stops.” In general, the aperture is determined on the basis of quality and quality. For instance, when looking at the best SLR lens, one might have two lenses with an identical focal length. However, they have different F-stops. The lens with the lower f stop is usually higher priced due to the higher luminosity.

The aperture settings permit more light to pass through the camera as the f-stop numbers decrease. On the other hand, the amount of light that enters the camera decreases as the f-stop number increases. It is possible to use the aperture to compensate for any changes made in the speed of the shutter. In the event that the shutter speed has been set too high and we want to raise the aperture so that more light can go into the camera. In the same way, we can reduce lighting entering by closing the aperture and decreasing your shutter speed.


Before the advent of digital photography,” film speed” or “film speed” was often used to refer to”film speed” to refer to the ISO rating of the film. When the ISO grade raised, so did its sensitivity to light. The capability to increase the film’s sensitivity enabled photographers to shoot in low light conditions without dependence on axillary lighting sources, like a flash. Of course, there’s always a trade-off to compensate for a loss. The light sensitivity trade-off was made at the cost of an effect referred to as film grain. It is commonly called “noise” when it comes to the online realm. Film noise, also known as grain, can be easily recognized by the appearance of light or red and blue dots that are scattered throughout the image.

Because digital cameras do not utilize film, ISO is the sensor’s sensitivity level. If we increase the quantity of ISO that the camera will require less light. That is why it has the ability to adjust the shutter speed and aperture. If, for instance, you’re planning to shoot an action photo in the midst of a rainstorm without setting the aperture wide open, you can boost the ISO setting and still maintain an extremely fast shutter speed. The majority of digital SLR cameras feature advanced technology to compensate for noise, which was an issue with older models.

The fine distinction between what shutter speed and aperture setting are related to, as well as ISO sensitivity. But, with time and experience using your camera, you’ll discover how to utilize the light you have to get professional images every time. Although no camera functions exactly the same way, knowing the basic connections will have you being a professional photographer within a matter of minutes.
