To achieve photos without noise, you can usually choose the lowest ISO setting on your camera, which is in most cases 100 (although some newer cameras allow ISO as low as 50). You generally want to avoid this as much as possible unless you are aiming for an artistic shot and purposely want more grain. Understanding ISO is important because with an increase in ISO comes an increase in noise, or grain, in your photos. However, if it is dark and your subject is moving, you will need to tweak the ISO settings a bit more. With backlighting you might want to decrease the aperture size by a few stops to compensate for the light coming in and keep the ISO setting low. If you are working with backlighting, your settings will differ from if you are in a dark room with little light. Just like outdoors, in indoor photography you will also need to determine the source of light. As the surrounding light gets darker, keep adding more stops to the aperture. For a heavy overcast sky add 3 stops, and so on. For an overcast sky add 2 stops to f/16, making the aperture opening to f/8. To do this, just add 1 stop to f/16 which should give you, f/11. So in a partially overcast situation you would need to make the aperture bigger than in bright sunlight. Remember the key principle is to let more light in through the aperture as the surrounding light decreases. Let’s look at another example where this rule can be applied: This will give you a shutter speed of 1/200 or 1/180 which is the closest setting to 1/200 on your camera. Your best aperture setting will be f/16 and your shutter speed will be the reciprocal (the reciprocal of a number is 1 divided by that number) of 200 as your ISO is set to 200. This simple rule will help you determine the exposure easily just by examining the type of setting you are in. This rule basically states: Set the Aperture to f/16 in bright sunlight and the shutter speed to the reciprocal of the ISO setting. One of the rules that you will hear photographers often refer to is the Sunny 16 Rule. For now, let’s focus on how exposure relates to the amount of light present in a given situation. #F stop cheat sheet how to#I will be giving an easy to remember example of how to understand these three components at the end of this article. They are also directly connected to the outside setting and the amount of light naturally present in the environment, whether it is the sun, backlighting, or an overcast sky. While these three settings can sometimes be daunting to understand, knowing them properly can help you create some amazing effects. This delicate balance is handled by three main components: ISO, shutter speed, and aperture. A properly exposed photograph will have a perfect balance between light and dark, or in other words, between the amount of light entering the camera and what the camera chooses to block. Too little, and it will be dark and under-exposed. Too much light, and the picture will be over-exposed. Just like our eyes see things in light, a camera captures a photograph as a result of the amount of light that enters it.

Mount St.The Essential Connection Between Light and Photography The sunny 16 rule is one possible starting point, but it's still up to you to do the thinking. With practice, you will think less of lists, more of getting the shot. So, you want to learn how to ask yourself what shutter speed do you need for what you are shooting (action? wildlife? landscape?) then decide what aperture will get the depth of field you want or allow, say, a faster shutter speed, then adjust your ISO to obtain the right exposure. Think #possible_shutter_speeds * #Possible_apertures * #possible_ISOs and you come up with a large number that represents the many varied possibility of scene/subject matter/conditions. The problem with doing something more comprehensive is that there are too many variables. I should say that the above list applies mainly to still/scene/landscape types of shots - no moving subject and a tripod when the shutter speeds get slow (it assumes f/8 at ISO 400).
