What is Shutter Speed? The higher the number, the fast the shutter will open and close. Each lens has its own aperture range. Fundamentals of Photography — Understanding Aperture Putting ISO, Shutter Speed and Aperture Together The easiest way to think of how all three work together to give an exposure is to keep one of the three components constant. The next step is to choose your f-stop or aperture. Therefore, if using a wider aperture lower f-stop number you are letting in more light and therefore your shutter speed should be faster compared to when using a narrower aperture higher f-stop number for the same given exposure.
An example for you: To see why I love shooting in aperture priority mode over manual sometimes check out this read. We can control how much light hits the sensor by: With the lid on you can leave the bucket for longer time in the rain.
However changing the size of the buckets all the time is unpractical.
Understanding aperture and shutter speed
You should always keep the ISO lowest your camera allows. This way you ensure the best possible image quality. How long it will take to fill the bucket depends on: Everything except the light, right? In landscape photography, you have very few possibilities to control the light yourself. On each of the tree sides of the Exposure Triangle, the numbers on the scales are equally distributed with one f-stop between each.
If you change one the sides up or down, you will have to compensate the same on any of the two other sides. The grid indicates all the possibilities you have to combine aperture, shutter speed and ISO for the desired exposure.
Changing the ISO itself will not give you any creative options. The only exceptions are if you by purpose want noise or grain in you photos. But if you want to simulate old film grain I suggest you shoot a regular photo and add the grain in Lightroom or another imaging software later.

Basically, this will be in low er light situations. How wide the ISO scale is, is limited by your camera. Creative use of aperture - not so much in landscape photography In landscape photography aperture is important for one purpose, getting as much of the scene in focus as possible. This is a challenge landscape photographers meet most of the time. Aperture is closely related to Depth of Field. Read more about other lens features here. If you purposely want some of the scene out of focus, you choose a wide aperture like f2.
At a given distance to the subject at constant focal length, the smaller aperture you choose bigger f-numberthe more of the scene will be in focus.
If you need to stop the lens all the way down to f22 for sufficient Depth of Field, do it. Some photographers avoid using the smallest and biggest possible aperture of the lens because the image sharpness is not optimal. On the Exposure Triangle, the aperture scale is limited by the lens you use.
The Exposure Triangle can make you a better photographer
I use and play with shutter settings a lot, longer shutter times. Creative use of shutter speed is the easiest one to recognize in a photo. When clouds are blurry, waterfalls are white and silky, star are moving on the sky you know this is the use of long shutter speed.
For landscape photographers, long exposure photography is important, and you will see a lot of images shot at long shutter speeds. On the other end of the shutter scale is the extreme short shutter speeds. Short shutter speed is used when you want to freeze motions. In landscape photography, extreme shutter speed is not required very often.
How the Exposure Triangle makes you a better photographer
The fastest moving objects in landscape photography is probably moving water fall. On the Exposure Triangle as I already mentioned, both the aperture and ISO have a fixed scale depending on the camera and lens you use.Pick the Best Aperture, Shutter Speed and ISO Settings
It is probably reasonable to expect a digital camera with a maximum ISO of to produce very noisy images at ISO while a camera with a maximum ISO of k will tend to produce less noisy images at ISO due to better electronics and better signal processing. Humans have finer control over digital devices than photosensitive chemical processes. You need to balance the depth of field that the aperture settings give with the amount of movement that the shutter speed provides with the amount of noise the ISO setting provides.
If you're concerned about one of these factors more than the others for a particular shot you should try choose that setting you want and adjust the other two settings to get the correct exposure.
In your particular case you're interested in reducing the amount of noise, so you should select the highest ISO that provides an acceptable amount of noise and then us your camera's meter to select aperture and shutter speed settings for the correct exposure. In general most people try and keep the ISO setting as low as they can, for example my camera goes down to Most modern cameras I have used have acceptably low noise up to about At that point it becomes too noticeable for me taste, but that's really a judgment call that only you can make for your photos.
