The following guest tip on The Beauty Of Large Aperture In Digital Photography was submitted by Amy Renfrey – author of the Digital Photography Success ebook.
In digital photography there is one thing that, for crisp images, you simply must know about. And that’s the proper use of your aperture. When you use your aperture the right way in your digital photography you can really influence a lot of creative factors. What I am about to tell you will help your digital photography a lot, because you’ll be discovering a professional digital photography technique.
In digital photography there are measurements of light control called ISO, Shutter speed, E/V and Aperture. The most important thing to start with in digital photography is to “get your head around” aperture and how ti controls many creative aspects of digital photography.
As you know digital photography images depend on just the right amount of light falling on to the sensor. An aperture, measured in F stops, is a crucial aspect to how much light the camera gets.
A large aperture allows a lot more light to fall onto the sensor, and when this happens you have the freedom of using a faster shutter speed. This is especially handy in situations of low light and fast movement, such as indoor sports or a water fall at the end of the day. That’s why larger apertures and fast action shots indoors need to go hand in hand. By widening your aperture you have a better chance of the movement being “frozen” in time and the camera won’t have time to think about camera shake. If done right, you’ll find good sharp images of freeze frame shots without any blur at all.
In your digital photography you should also know that also a large aperture can give you a crisp depth of field. It gives you the opportunity to have your background out of focus giving you clearer focus for the subject close up. (You should always use macro lenses for very, very short depth of field because you get more clarity and sharpness. You can get in closer too, without the subject blurring as it would have without the macro lens.) Portrait photography works well this way.
On the other hand, a small aperture in your digital photography gives you the opportunity to get a slower shutter speed because once light is reduced onto the sensor, the shutter speed will respond.
A smaller aperture in digital photography increases the depth of field because it influences the focal length. When you have an increased depth of field you will notice much sharper images in long distance shots such as landscapes and cityscapes. So if you are having any challenges with lighting and movement then try this digital photography tip!
