#Iso f stop shutter speed chart iso
Like in actual photos, let's look at apertures, shutter speeds, and ISO settings.
Now that you have a handle on thinking in terms of stops, and an idea what stops look Knowing how and when to vary from the camera meter's recommendations is the difference between average exposures and great exposures! As you will learn in another article in this series, many subjects look best when they areĮxposed at a different exposure setting than the one the camera meter recommends. As an example, all the photos in the left handĬolumn were exposed at two stops less than what the camera meter suggested. The photos in the other columns were exposed at one or two stops more or less than what the camera meter recommended. The zero over the center column means the photo in that column were exposed according to the camera's meter reading The numbers in the top row of photos indicate whether the photos in that column wereĮxposed using the camera meter's recommendation. The photos in the far right columnĪre four stops lighter than the photos in the far left column. As you move from left to right in each row of photos, each photo has one stop more exposure than the one to it's immediate left. You will see this illustration again in a metering article.Įxposure Tonality Chart in One Stop Incrementsġ8% Gray Card (top row), red cloth, clear blue sky,įive different subjects were photographed using five different exposure settings on theĬamera. This illustration will give you an idea what exposure looks like in one stop increments. The human eye is not a good judge of exactly how much light there is, which is why we have light meters. Like stops, each "step" refers to the doubling or halving of the amount of light. Than in the shade of that building." Or to how much light you allow through the camera, as in "I reduced the exposure by one stop of light."įYI: In some photo books and articles you will find the terms "steps" used instead of Stops can refer to how much light is available, as in "It is four stops brighter in the sun With most recent camera meters, the light can be measured in 1/2 and/or 1/3 stop increments.

If the light has changed, but not in even full stop increments, the increase is measured Light means there is only 1/4 as much light, three stops less means 1/8 as much light and so on. "One stop less light" means the amount of light has been cut in half. Three stops more light means _ (fill in the blank)? The answer is 8 times more light (doubled three times).
There is four times as much light (the light has been doubled twice). "One stop more light" means the light has been doubled. Just what is a "STOP"? A "stop" means the amount of light has been doubled or cut in half. Speed, and ISO settings on the camera are all indicated in stops and fractions of stops. If you want to speak your camera's language and make it do it's tricks for you, you need to understand the language of exposure.īefore we look at the big 3 individually, you need to think in stops. They are the threeĬamera settings that determine the exposure for every photo you take. Speaking Your Camera's Exposure Language:Īpertures, Shutter Speeds, and ISO Settings are Exposure's Big 3.
