Isolate the subject from the background

To shoot still life or people, canvas prints we often encounter a problem, that is an expression of background clutter interferes with the body, this time, we may choose to change the composition of a picture, looking for a background, there will be no interference or directly to the main body and background, through some means to make the subject more prominent, let the expression of background will not interfere with the body.

1. Use lighting

When most photographers think about isolating the background, canvas photos online they usually think about light, using the contrast of light and shade to make the subject have enough light while the background is obviously underexposed, which can easily highlight the role of the subject. This use of chiaroscuro to highlight the subject is particularly applicable to portraits in street photography.

When shooting, we should pay attention to the light conditions in the environment, such as some large areas in shadow that are not affected by the light are suitable for the background, and we can enhance this effect by pulling down the dark details in the later stage. But in the early time to also want to pay attention to the camera's exposure, if the contrast is too large, if exposure to shadow, frames for canvas prints shadow detail has the light details and lost, at the time of viewing photos must always pay attention to the manual exposure and can according to the environment rapidly adjust our camera Settings, in order to obtain the appropriate exposure, while can highlight the main body, and the dark parts remain in the background area.

2. Use depth of field

Depth of field should be the most effective way to separate the subject from the background. By controlling the focus and opening the aperture, we can make the background completely out of focus and blurry. Many portrait photographers like to use the large aperture of a medium long lens to achieve this effect.

As long as the distance is properly controlled, most of the lenses above the focal section of the standard lens can achieve the effect of background blurring, but it should be noted that the limit of shallow depth of field is not always good, if the aperture is turned to the maximum, regardless of the quality of the picture, it may also cause the body of the subject to lose focus due to the extremely shallow depth of field. When the aperture is turned on, the spot in the background will become larger, which will sometimes cause the effect of interfering with the background. Therefore, before pressing the shutter, you must try first, and then choose the aperture value most suitable for the current scene.

3. Use composition

In fact this is a supplement to the front points, by contrast, or sometimes through a shallow depth of field still is not up to isolate the effect of background interference, this time we need to move the camera and watch what happens in the background, and then choose the appropriate background in the process, not too many elements to spread the main body. Or change the Angle of view, such as when we use the eye level perspective because down from the perspective, there may be some background elements appeared in the picture, and then we switch to low Angle from down to up the perspective, the environment looks more certainly than neatly below, also won't have so many, large canvas prints australia the expression of interference to serious interference images.
