PHOTO background blur Tricks


Pictures of the main target is strong, weak or out of focus while the background always attracted attention. Especially if you focus on a particular object images. An example of an image with objects such as types of portraits, flowers, animals or other objects to determine how do the image side.

Such images that have a so-called "shallow depth of field." Depth of field (DOF) is itself a core depth of the camera, the more narrow DoF (shallow dof), less sharp.
Pictures of "shallow dof" can be created either by the type of SLR cameras (eg Nikon D70, Canon EOS 350D, Konica Minolta Dynax 7D, etc.) .. In the meantime, if you have a background image for a blurred image with "Pocket Camera" (like the Canon PowerShot A400, Sony DSC 600, etc.) can be taken with digital tools such as "Photo Shop" or "Corel Photo Paint." Steps are explained in the process later in the second part of this work. This type of pocket cameras have limitations in terms of "Legth center" it is difficult to create images that with a blurred background.
Here are some steps to consider to add the background image has been damaged (shallow dof) the techniques of photography:
1. Put the main theme, with a background as possible. It is possible if we take the object from the type of photographic portraits of models. An example like this picture, a greater distance of the object with the background blurred background image produced best. Set against the background of the image is a wall that is close to the model, the attention of the model and the wall.
A little hard to do if the image of an object can not move, as an example the picture above is the light bulb, but the technology can be used in paragraphs 2 and 3.
2. Set the aperture or opening (opening more understanding from previous posts) camera with a wide aperture (small number of selected) My proposal below 5.6. Figure F-6 was still possible, especially if the distance in the background, but below it was the best result. Number of objects in the vicinity with his background, the aperture (aperture), as small as possible under existing lighting conditions. My advice is still good to different combinations of light from f / 2.8 to 5.6 of course, try the outcome will be different, and sometimes take pictures even more impressive.
3. Use a telephoto lens. Is a telephoto lens with focal length range. The lens is easily recognized by its length. Telephoto lens has the effect of the closure can produce very narrow DoF. I've never seen pictures of the players in the middle with a blurry background photo? Or has photo Hollywood stars, the paparazzi, there are millions of dollars? The images were mainly caused by the use of telephoto lenses. Another used a telephoto lens the shutter button, so that various other objects, which are increasingly blurred the background. Creating objects stand out along the main road blurred background with a long telephoto lens combination of the opening, the most commonly used by professional photographers, the most important things that stand out to stay strong and displayed in the center of attention.
