The main factors that determine depth of fields are aperture size, length of lens focal length and distance of the object being photographed. Shallow depth of the subject can be separated from the background (sometimes the foreground), so that only the main body of the focus and the background is virtual. The use of this technique visually stretched the distance between the subject and the surrounding background, making the subject more prominent in the picture.
The use of optical circles and shutter depth is the technology that the SLR group needs to accumulate over the long term, while the ordinary card camera takes the shallow depth of the picture to be satisfactory. Therefore, if you are not confident about the manual control of depth, but want the effect of shallow depth, then the later is necessary. Today, a simple late-stage approach is introduced, even if the photos taken by a normal camera can simulate the effect of shallow depth with a good photo.
Good photo is a simple and easy-to-use photographic software, easy to operate, powerful, very suitable for the use of photography novice.
Picture one, background clutter of the original artwork
Figure II, the effect of shallow depth of the treatment
Figure II, the modified picture clutter background is blurred, only the main body is clear, simulating the effect of shallow depth of the ground.
First, open the picture, select the axis, choose the appropriate mode and aperture size according to the picture. Good photos offer four kinds of blur, including "Portrait", "Architecture", "Landscape", "macro". At the same time, good photos also provide a different aperture size, to reflect the different effects of the virtual. To achieve the effect of shallow depth, recommend the use of large aperture.

Here are some examples of good photos that simulate shallow depth:
Figure Four, use good photos to the portrait of shallow depth of treatment

For users who want to simulate shallow depth in the late stage, try this simple, but excellent software-good photos. Even without the SLR, even the novice photographer, even if not PS, good photos can help you get professional-grade work.
