Photography how much is 1 stop

What I want to show you in this article is how the concept of a stop acts as a common currency in exposure, and allows you to take complete control of it. Rather than being confusing, stops are really a simplification tool.

To see what I mean, think about the barter system before we had money. If you sold chickens, I sold apples, and someone else sold bricks, how would we all trade? It was a mess, which is why the concept of money was developed. Now we all value our goods using money and we exchange money with each transaction.

This has proven to be a remarkably useful tool, which is why it has stuck around for a few thousand years. Similarly, in photography we faced trade-offs when it came to exposure. For example, how could we value a change in the size of the aperture versus lengthening the time of shutter speed? And then how would we value the sensitivity of the digital sensor or film in the old days as compared to these other two adjustments?

The concept of stops is how we square everything up. Understanding this is a necessary precondition to mastering your camera and controlling the exposure process. Hopefully this will help you grasp your exposure controls better. Your shutter speed is a measurement of time. As you probably already know, when you open up the shutter, the camera is gathering light. The longer you allow the camera to gather light, the higher the exposure value.

Most shutter speeds you use will be a fraction of a second, but here are the common values for shutter speed you will see when you look through your viewfinder or at your LCD:. The segments in this chart are 1-stop increments. Again, a stop is a doubling of light.

Remember that shutter speed is a measurement of time, so a doubling of the time your shutter is open is the same thing as a doubling of light. You have doubled the time the shutter is open so you have also doubled the exposure value. It will take three clicks to move a full stop.

It looks something like this:. The point is to understand that we are taking a time measurement and converting it into a stop. Each doubling of the amount of time the shutter is open equals a stop. Conversely, you reduce by a stop every time you cut the shutter speed in half. As you probably know, the aperture is the hole in the lens that lets light through into the camera, and it is adjustable. Making it larger lets more light into the camera; making it smaller lets less light in.

To change your exposure value using the aperture control, you are changing the size of the aperture. Best iPhones. Best External Hard Drives.

Depending on the brand and model, you may have ISO ranges outside of this.

Just like before, a full stop in ISO is the doubling or halving of the setting. Luckily ISO is made up of numbers that are extremely easy to work with.

The stop range in ISO goes like this:. Each increment represents one full stop of exposure change. As the number increases, the photo becomes brighter. Just like with aperture, there are additional ISO settings in between these full stops.

Again, these are fine to use in your photography, but they will not change your exposure by a full stop, rather something in between. If you want to take a good quality picture, you must get your exposure right. If your exposure is too bright or dark, you lose detail in parts of your image that can be unrecoverable, even with post-processing. By striving to capture an even exposure in every photo, you are improving the overall quality of your image.

An even exposure will have the most detail and look more accurate to real life. Learning how to use stops in photography is the easiest way to find a balanced exposure. Far too many people rely on fixing the exposure of their photos in post-processing. No photo editing required. Trying to figure out what a stop is in photography can feel pretty confusing at first.

What appears as a complicated way to figure out your exposure becomes an easy way to quickly adjust your camera settings. By remembering to double or half any exposure setting, you can easily find ways to balance out your light meter and find the perfect exposure in any situation.
