It is also possible to add up to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds. Do you want moving objects to be razor-sharp or have motion blur?Don't panic!

Although exposure can be shifted in full stops, you get much finer control by adjusting the exposure in these smaller increments.Sign up to get breaking news, reviews, opinion, analysis and more, plus the hottest tech deals!Thank you for signing up to TechRadar.

However, increasing the ISO also reduces the quality of your images.Use the exposure triangle to decide how to adjust the exposure: the key is that when you increase the exposure for one element (a yellow arrow), you need to reduce it for one or both of the other elements (the grey arrows) in order to maintain the same 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.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. The longer your shutter speed, the more blur and motion you’ll be able to capture. For instance, a shutter speed of 1/50 sec is one stop slower than 1/100 sec, which means the sensor is exposed for twice as long. Motion blur: The key to creating motion blur in your photos is shutter speed. 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. To help people wrap their heads around the concept, photographer Drag the sliders to see how the resulting photo changes. As soon as you make a decision about one element, you'll need to compromise with another.The trick to balancing The Exposure Triangle is to get all three elements working together so you get the results you want ,and not what the camera tells you you can have.Because of that, it's really worth putting in the groundwork and getting to grips with the basics of shutter speed (how long the camera's sensor is exposed to the light), what an aperture is (how much light the lens lets in, which also affects depth of field) and ISO (the sensitivity level of the sensor). Low-end Android devices and the Exposure Triangle. 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 set the shutter speed, and the camera attempts to match this with an appropriate aperture. Now, let's take a look at some of the common questions new photographers have about exposure...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. NY 10036.

These represent half-stops or third-stops, depending on how your camera is set up. Now that we know the concept of the exposure triangle, how does it all translate to mobile devices?

The relationship between the range of apertures available on a lens is similar, but the numerical sequence is more confusing: the fact that f/5.6 is one stop smaller than f/4 but one stop larger than f/8 takes a bit of getting used to.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. Once you set an aperture in Aperture Priority mode, for example, the shutter speed will be set automatically. The exposure triangle can be manipulated to create different effects in your photos. Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated. This is usually expressed in the order of a shutter speed value at a given aperture and ISO - say 1/60 sec at f/8, ISO 200.In the camera's automatic and scene modes, that's about as far as it goes. Shutter speed also affects image sharpness, with slower shutter speeds leading to blurred images - whether that's caused by the subject moving or the camera not being held still.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. It's all about balance: if you increase one of the three settings that control the exposure (aperture, shutter speed or ISO) then one or both of the other settings have to decrease by an equivalent total to maintain the same overall level of exposure.For example, an exposure of 1/25 sec at f/16, ISO 100 is equivalent to an exposure of 1/400 sec at f/2.8, ISO 100. It's also measured in stops: the exposure indicator scale you see in the viewfinder or on your camera's rear display has stops clearly marked on it. © This is where exposure compensation plays a part.Exposure compensation can be applied in Aperture Priority, Shutter Priority or Program mode. Creating a harmonious exposure using the aperture, shutter speed and ISO is a juggling act. You can usually increase or decrease the exposure by up to five stops.You'll see that there are smaller marks on the scale, too. You can even use the Auto ISO option to let the camera handle that choice of sensitivity too.
