The Exposure Triangle: aperture, shutter speed and ISO explained | TechRadar
Beginner Photography Master ISO, Aperture, and Shutter Speed. Go from Auto to Manual Settings, Understand Depth of Field, Exposure, Which Lens to Buy. 1) How Do Shutter Speed, Aperture and ISO Work Together to Create an Exposure? To have a . Understand the relationship? Now change. Then you are left to simply determine the DOF and shutter speed you DOF ( larger aperture) would be acceptable (assuming the shutter speed is . light and the SNR ratio is thus lowest), if the scene, or at least the subject, .

Aperture And Shutter Speed: The Art of Imperfection
The only downside is that the higher the ISO, the grainier the picture will be. Aperture If you literally know nothing about how cameras work, this might come as a shock: So the glass piece on the end of your lens is not actually the size of the light-capturing hole; it exists to direct the light towards the aperture.
The affects of adjusting the aperture are self-explanatory: But how does this affect your photograph?
The Focal Ratio Aperture controls depth of field, as well. The smaller the aperture, the wider the depth of field; the larger the aperture, the narrower the depth of field. But all you really need to know is that the smaller the f-stop number, the larger the aperture opening, and vise versa.
So how are these numbers related? Anytime you move down a stop for example, from 1.
Almost needless to say, anytime you move up a stop, such as from 4. Shutter Speed The film of your camera is protected by a window that opens and closes.
This is called the shutter. Shutter speed, then, refers to the length of time the shutter stays open.
These times are expressed in seconds. Interestingly, the same relationship that exists between f-stops exists between shutter speeds. Since this is a matter of doubling or halving time, it is easier to understand than aperture.

But by this time you should be able to see how aperture and shutter speed affect each other. The Art Of Imperfection In the most general sense, the smaller the f-stop i. 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.
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? 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.
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. It's all about balance: Which combination you choose is down to the look you want to achieve: Do you want moving objects to be razor-sharp or have motion blur?
That's a lot to think about If you choose to shoot in one of the semi-automatic modes, the camera does most of the donkey work for you. Once you set an aperture in Aperture Priority mode, for example, the shutter speed will be set automatically. If you decide to change the aperture, the camera will adjust the shutter speed accordingly to maintain the same exposure.
It's a similar story with Shutter Priority mode:
