In photography, light is controlled by the “exposure triangle": ISO, aperture, and shutter speed. Understanding how they work will help take your photography to. is the relationship between ISO, aperture and shutter speed. This handy chart below would have saved me much time and tears if it were. 1) How Do Shutter Speed, Aperture and ISO Work Together to Create an Exposure? To have a . Understand the relationship? Now change.

The drawback to increasing the ISO is that it makes the picture noisier. Digital noise is apparent when a photo looks grainy. Have you ever taken a picture at night with your cell phone or your pocket camera, and noticed that it looks really grainy?

That is because the camera tried to compensate for the dark scene by choosing a high ISO, which causes more grain. Camera companies are constantly improving the ability of cameras to use high ISOs without as much grain. Since each camera is different, you would do well to do a few tests with your camera to see how high of an ISO you can shoot at without making the image overly grainy.

Photography Tutorial: ISO, Aperture, Shutter Speed

In JanuaryI took a trip to my favorite place on the planet to take pictures—Yellowstone National Park. My guide informed us that the bighorn sheep in the park were dying off very quickly due to whooping cough, so I worked hard that week to capture pictures of the last few sheep in that area of the park.

Around 9AM on a cloudy day, I found a small group of bighorn sheep and started photographing them with a long mm lens. The early hour and clouded sky made the situation quite dark for shooting.

This also impacted the depth-of field to blur out the rocks behind the bighorn sheep. 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: You can even use the Auto ISO option to let the camera handle that choice of sensitivity too. In Program mode, you can simply shift the combination of aperture and shutter speed with a spin of the camera's control dial.
