How to Get a Correct F-Stop

Have you ever wanted to learn how to get a correct f-stop for your photographs? All cameras may have different f-stop ranges, but it doesn't matter unless you know how to use it. This page will guide you through learning how to get a correct f-stop.

The history of photography dates back to the 4th and 5th centuries. Chinese and Greek philosophers pondered the ideas of optics and soon were able to describe the basic principles of such a concept. That led to understanding the basic principles of how a camera could exist and work, even though it was not invented at the time. Time progressed and more people learned about the ideas of optics and expanded them. By 1814, Joseph Niepce was able to capture the first photographic image with a camera obscura--an old-fashioned camera used in dark rooms.http://inventors.about.com/od/pstartinventions/a/Photography.htm http://brightbytes.com/cosite/what.html Alexander Wolcott, in 1840, was issued the first American patent for photography. Although Wolcott is credited for the first camera, numerous others were able to develop photographic images including Niepce and Louis Daguerre. Since then, photography has developed considerably with cameras such as the digital camera (invented in 1951).http://inventors.about.com/library/inventors/bldigitalcamera.htm

Setting the f-stop correctly is important in creating the perfect photograph. Decide on how much light you want in a particular shot before changing the f-stop setting. This page will guide you through three simple steps in understanding the f-stop feature and getting a correct f-stop setting.

Before you can use an f-stop, you must understand it. An f-stop is usually combined with shutter speed to create the exposure you want for a particular photograph. The f-stop regulates how much light gets into the lens by changing the area of how much light can enter. This changeable area is called the aperture which is much like the iris of an eye. It shrinks or enlarges, depending how much light it wants to let in. For instance, our irises get smaller when we look at brightly-lit objects like lamps or even the sun. Our iris then becomes larger when there is less light in a room, allowing us better vision in darkly-set areas.

The f-stop settings are measured by numbers. This number is best understood as a ratio: between the diameter of the aperture and the focal length of the lens. Some people get confused with the numbers: the higher the f-stop number, the less light that comes into the lens.http://www.uscoles.com/fstop.htm

Now that you understand the basic principles of the f-stop feature, it is time to consider them with different lighting you may want. Like said in Step 1, the higher the number, the less light that is allowed in the lens and the lower the number, the more light that goes into the lens. That number indicates if the aperture is open (low number) or if it is more closed (high number). F-stop allows you to control how much light you want in a particular photo you are trying to shoot.

Before you change the settings of the f-stop, make sure to envision what kind of photo you want to shoot. Do you want a lot of light or do you prefer a darker photograph? These questions are important for determining what number to set the f-stop to.

All cameras have different f-stop settings. For example, one could have a low f-stop of 3.5 and a high of 22. Remember that the lower the number, the more light that is allowed in the lens. Find the f-stop setting on your camera and change it according to the light you want in the photograph.
