Depth of field
There is a certain way that experienced photographers take such stunning pictures, portraits and photographs where the subject being shot is focused in a clear and perfect manner while the background is sort of a blur.
The following are the steps to take those amazing picture-perfect shots.
The technical
First things first, it is best that the camera being used has a plate for imaging that is large. Also, a lens that is considered fast should also be used. “Fast” in photography language means a lens that has an aperture that is larger than f2.8.
When the aperture of a camera is large, the image or picture that will be produced has a depth of field that is shallow. In photography language, this basically means that the area that is behind as well as front of the subject being taken is a blur.
As much as possible, the shoulder and the head of the subject should fill the whole frame. Also, if the subject is a person, don't forget to focus on the subject’s eyes.
The technique
Practice really does make perfect. There is no such thing as a perfect job done only once. It takes perseverance as well as patience. When shooting pictures, try to take a series of shots using a lens that has a wide opening and a stop on at least one or two.
Focus on various areas such as the ear, nose, hair using varying apertures for such. When the pictures come out, you then have many different options to choose from.
To be able to create a depth of field that is shallow, the best thing you should do is use a long lens – preferably a telephoto – and have it set on the zoom that at its maximum. Then, try to stand as close to the subject as possible.
However, for subjects that are in motion, for example a car. The camera must then be moved the same way the subject is moving. Or simply put, the subject must be followed. The best film to be used for such a shot are ISO 400 films. Also, don't forget to set the camera at an ISO setting that is similarly fast.
The body of the camera, especially when taking such moving picture shots, must be steady. Make sure to focus on the subject as you see it through the lens of the viewfinder. Using such a technique ensures that the subject being focused on is clear and crisp while the background is a beautiful blur. Such a picture helps highlight the movement being done by the subject therefore making it seemingly jump from the picture.
Photo effects
Believe it or not, there is also an easy and stress free way to create a similar photo effect without doing the techniques mentioned. This has become possible through the magic of software. Photoshop has a “blur” function, which blurs the picture’s background in a uniform manner independently as well as authentically the way an actual photograph may be done by a technically-savvy photographer. The software blur is and looks artificial while the real blur is more organic in feel.
Fortunately or unfortunately, the technology of software is advancing so that there is a CS2 version of Photoshop that enables anyone to create a blur that is considered as “smart.” This function takes into consideration the picture’s depth of field. This basically means that the function applies a lot of blurring effects to the pixels that appears more distant and applies a lot less blurring to the pixels that appear nearer. Believe it or not, such a function is adjustable that anyone could achieve any effect desired.
All in all, depth of field is a fairly easy concept to understand especially to those serious in learning the art and craft of photography. All it takes is a lot of patience, perseverance and a heart that is willing to learn as well as a mind that is open to making mistakes and gradually correcting them along the way towards creating a picture perfect shot.
