![]() Once you get away from the capital city of Reykjavík, you’ll notice that there isn’t very much light pollution in Iceland. However, the most important time during which you should use a wide aperture for your landscape photography in Iceland is at night, when the Northern Lights come out to play. For example, if you focus on a puffin in the foreground at a wide aperture of f/2.8, then the puffin will be in focus while the background will be soft and blurred.Ī wide aperture results in a blurred background. Wide or open apertures, described as low f-stop numbers, are typically used to blur backgrounds for a dreamy effect or to create bokeh.

On a 16-35mm f/4 lens, the mid-range sweet spot and sharpest aperture would be between f/8 and f/11. Therefore, if your lens value is 1:2.8, then counting up two or three f-stops from 2.8 will give us a sweet spot of between f/5.6 and f/8. The general rule to determining the mid-range sweet spot of your lens is to count up two or three full f-stops from the widest aperture.į-stops lie on a sort of exponential scale. In this context, the 2.8 refers to the widest (maximum) aperture that your lens can handle. This value will help you to determine the mid-range of your lens, which in turn will help you calculate its sweet spot. On the side or at the end of your zoom lens, you may have noticed some strange values that look a little like this: 1:2.8. ![]() This range is carefully measured and is known universally amongst landscape photographers as the ‘sweet spot’ for your camera lens.

Therefore, one of the most important things to consider about the lens that you’ll be using for landscape photography in Iceland is what its optimal aperture is for front-to-back sharpness.Īn optimal aperture for front-to-back sharpness is between f/7.1 to f/13. This affects the overall sharpness of your image. ![]() That is, even though it’s a tiny number, f/2.8 results in a big aperture, whereas f/22 is regarded as a small aperture.Īside from the amount of light that it lets in, your lens aperture will also help you to control your depth of field. This is otherwise known as the f-stop value, which in reality is inversely proportional to aperture value. The bigger the aperture, the larger the hole and the more light that is able to come in through your lens to reach the sensor of your camera. So, while neither the focal length nor the aperture diameter are affected by the body the camera is on, theį-stop is also affected.First thing’s first – the aperture refers to the size of the opening in your lens which allows the light to enter. This is important, because the density of the light is the exposure. Of the light falling on the sensor, and, in combination, determines the The f-stop, on the other hand, determines the This is of central importance because it is the total light, along with sensor efficiency, that determines the total image noise (not ISO or sensor size, as most people think). The aperture, in combination with shutter speed, determines how much The "f-stop" is the ratio of the focal length and the aperture diameter: f-stop = focal length / aperture diameter. The "aperture" is the diameter of the entrance pupil of the lens, and is measures in mm. While I'm fully aware that people use the terms "aperture" and "f-stop" interchangeably, they are, in fact, two very different, but related, measures. As this is completely a function of the lens, the size of your sensor will not affect it in any way. ![]() A higher f/stop number equates to a smaller opening inside your lens. Aperture (f/stop) is the size of the opening inside your lens through which light passes.
