Photography Basics Aperture, Shutter speed, and ISO | Improve Photography
Aperture and Shutter speed are undoubtedly the two most important technical ( check out this post for 10 tips on improving your photography). In order to do this, it's essential to understand the 3 components of what we call “ The Exposure Triangle”. These are: aperture, shutter speed.

This is a very shallow depth of field and was taken with an aperture of f2.
- Understanding the Relationship between Aperture and Shutter Speed
Image by Trevor Cole. Aperture has a big impact upon depth of field.
Another example of large and small aperture Let me illustrate this with two pictures I took earlier this week in my garden of two flowers. The difference is quite obvious. The best way to understand this topic is to get your camera out and do some experimenting. This ensures that from the foreground to the horizon is relatively in focus. On the other hand in portrait photography it can be very handy to have your subject perfectly in focus but to have a nice blurry background in order to ensure that your subject is the main focal point and that other elements in the shot are not distracting.
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.
Introduction to Aperture in Photography
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.
Increase the exposure by one stop, and the camera sensor receives twice the level of exposure.Photography Tutorial: ISO, Aperture, Shutter Speed
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? Once you activate the camera meter by half-pressing the shutter release, the camera will suggest an exposure based on the brightness of the area being metered.
Understanding the Relationship between Aperture and Shutter Speed
In the camera's automatic and scene modes, that's about as far as it goes. The semi-automatic exposure modes - Aperture Priority, Shutter Priority and Program - give you more control over how you expose the shot, each in a different way; while Manual mode gives you full responsibility over aperture, shutter speed and ISO.
Although there might be a preferable exposure, there are a number of ways in which to achieve it. 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. 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?
