If you're photographing a car race or kids playing in the park, your number one issue is going to be motion and you're going to pick a higher shutter speed to arrest the motion, and then you're going to choose f-stop and ISO that allow you to use that shutter speed. When adjusting the f-stop setting on your camera when you turn the dial (or button) one click you are only going of a stop which is what most cameras are set to (or. Now, if you have your camera in front of you this will help make more sense. The way you choose which one to favor kind of depends on what you're doing. F-1.4 is one full stop brighter than f-2.8, f-2.8 is one full stop brighter than f-5.6 and so on. And that eliminates the overall ability of your camera to capture and hold fine detail. The higher your ISO, the more little random flecks of color are generated in your image that really shouldn't be there, that don't have anything in common with the tones around it and that has a tendency to make your image appear grainier and grainier and grainier, or fuzzier and fuzzier and fuzzier. That means that when one of these settings is changed, one or both of the. This image above was taken on a rainy day with an ISO set to 100. Aperture, shutter speed, and ISO make up the three corners of the Exposure Triangle. You can think of ISO as an artificial way of. The reason why I can’t give you an exact correct ISO setting is because no two light situations are exactly the same. Basically, the higher your ISO, the less light you need (allowing for faster shutter speeds and smaller apertures). Aperture settings are stated as f-stop numbers, or simply f-stops, and are expressed with the letter f followed by a number: f/2, f/5.6, f/16, and so on. A larger aperture allows more light to hit the sensor and. ISO controlled sharpness is a function of something called resolving power through signal noise or graininess. Note when recommending the correct ISO setting for shady conditions or rainy days, I’m also presuming your Aperture f-stop is set to around f/4 or there about. Using different combinations of aperture, shutter speed and ISO can achieve the same exposure. My question now is what impact would there be on the pic if I changed one or the other of ISO or F Stop. You also have to pick a shutter speed that's going to eliminate the motion of your own hands and your breathing and your heartbeat from your pictures, and usually the longer the focal length of your lens, the more telephoto it is, the higher the shutter speed you need to use to eliminate your own hand motion from your own picture. ISO and F Stop Settings - posted in Beginning Deep Sky Imaging: I took this pic last night and as discussed in another thread its mostly stars rather than camera noise which is good.
