ShortCourses-Using Shutter Speed and Aperture Together

shutter and aperture relationship

Those tools are shutter speed, aperture, and ISO. After I explain what each one does, I'll explain why we need three separate tools to control the brightness or. Jun 25, These are: aperture, shutter speed and ISO. By the end of this tutorial, you should understand what these 3 components are and how they affect. Feb 27, Two controls affect the amount of light that comes into the camera and strikes the image sensor - aperture and shutter speed. The ISO affects.

Next, I set my shutter speed.

I knew that this fast of a shutter speed would prevent any motion blur from the sheep running on the mountain side. Then, I took a picture.

Understanding the Relationship between Aperture and Shutter Speed

I couldn't compromise my shutter speed or aperture, so I knew I needed to use the third player in the exposure triangle—the ISO. I played around with my ISO and found that if I increased it to ISOit made the picture bright enough to take the picture without making it overly grainy.

This combination of shutter speed, aperture, and ISO worked out perfectly. Now can you see why you need to know how to shutter, aperture, AND ISO, and know how to set them independently on your camera?

The stops are arranged so that a change of 1 stop lets in half or twice the light of the next setting. If you make the shutter speed 1 stop slower letting in 1 stop more lightand an aperture 1 full stop smaller letting in 1 stop less lightthe exposure doesn't change.

In all modes other than manual this happens automatically. However, you increase the depth of field slightly and also the possibility of blur from camera or subject movement.

For fast-moving subjects you need a fast shutter speed although the focal length of the lens you are using, the closeness of the subject, and the direction in which it's moving also affect how motion is portrayed.

When photographing moving subjects shutter-priority mode is favored because it gives you direct control over the shutter speed.

The choice of ISO enables you to use the optimum combination of aperture and shutter speed when the amount of light would normally prevent you from doing so. However, increasing the ISO also reduces the quality of your images. Use the exposure triangle to decide how to adjust the exposure: The camera can do this for you in Program, Aperture Priority or Shutter Priority, but it's something you'll need to consider when shooting in Manual mode.

Pick the Best Aperture, Shutter Speed and ISO Settings

Get the hang of this relationship, and you'll gain much more control over the look and feel of every image you capture. It's also worth remembering that at one time, shutter speed and aperture were the only exposure variables you could change from one shot to the next as the ISO was set by the type of film you were using, but the introduction of digital cameras has made it possible to change ISO on the fly rather than unloading film or switching bodies.

Photographers now have more control over exposure than ever before. Now, let's take a look at some of the common questions new photographers have about exposure Understanding exposure in photography Exposure - allowing light to hit the camera sensor to record an image - is measured in what's commonly referred to as 'stops', with each stop representing either double or half the level of exposure of the adjacent stop.

Understanding the Relationship between Aperture and Shutter Speed

Increase the exposure by one stop, and the camera sensor receives twice the level of exposure. Decrease it by one stop, and the exposure level is halved. The three camera settings that give you control over the exposure - aperture, shutter speed and ISO - can each be measured in stops.

The relationship between the range of apertures available on a lens is similar, but the numerical sequence is more confusing: What's a correct exposure?
