We can often see some photos after the photo, especially the portrait, which is called the effect of having shallow depth, so what is the way for the novice to take this attractive photograph? is the equipment on hand enough? Let the author in this article one by one for everyone to answer it.

Question: I only have a 18-55mm set of lenses, can I take a beautiful shallow depth of the effect?

Of course you can. Even if you just have an entry-level DSLR and a set of lenses, beginners can definitely take a nice shallow depth of view. Just understand the 3 big shot out of shallow depth of the method can be.

3 large shot of shallow depth of the aperture to use long focal lengths camera, body and background distance ratio

These are 3 elements that take a shallow depth of view, is it simple? Let's start studying.

Tip one: Enlarge the aperture

The use of large aperture can easily make shallow depth, the meaning of large aperture is not necessarily to have f/1.4, f/1.8, such as aperture lens, even if the maximum aperture value f/3.5 set lens with the other 2 elements can do, try the aperture to the maximum can be.

Take a look at these three photos and you will understand the effect of aperture size:

The aperture f/2.8, the focus is in the bean Curd Aberdeen, after seeing two dolls also is outside the depth of view.

Aperture to f/5.6, focus on Tofu Aberdeen, see the middle of the red doll also gradually clear.

Aperture further small to F/16, the focus is still in tofu Tsai, see the final Snoopy also become more clear. When it comes to the actual shooting, if all the dolls are clear, we'd better focus on the red doll in the middle, so that the objects before and after are as much in depth as possible.

Tip Two: Use long focal lengths

Assuming the same aperture value, using a telephoto can make the depth of the scene lighter, for example: Lens A: Aperture F/4, using a 18mm focal lens B: Aperture F/4, using 200mm focal length

At this point, the depth of the lens B is lighter than the depth of the lens A, and the background is more masked.

Look at the following comparison chart:

Same aperture, with 50mm focal length, not too light depth

The same aperture, with 200mm focal length, will become lighter in depth than 50mm. (Pay attention to the bushes behind)

Skill Three: distance ratio of camera, subject and background

This is more difficult to understand in the text, the actual application means:

"Camera as close as possible to the main body, and the subject and background as far as possible"

In this way, even with the same aperture value and focal length, a photo with this technique will have a more background.

Just using the underground background, the background is not far enough, the depth is not too shallow

Use the road as the background, the distance with the flowers far, the depth of a lot of scenery

Summary skills

So a summary, for example, I am using the original set lens 18-55mm f/3.5-5.6, to take a beautiful shallow depth of view, we can have the following operations: The aperture to f/3.5, use the 18mm focal length or the aperture to the f/5.6, use 55mm focal length as close as possible to the main body to find an angle , so that the subject is far away from its background. shooting

This way you will be able to take a shallow depth of the effect.

Question: Why can't my aperture be tuned to "Max"?

A lot of beginners have similar problems when they try to shoot shallow depth. In fact, they use the lens is not a "constant aperture" lens, the zoom lens of the unsteady aperture is characterized by "maximum aperture value" will be the length of focal length to change, for example, the lens is labeled 18-55mm f/3.5-5.6, representing the 18mm end " The maximum aperture value is f/3.5, while at 55mm the maximum aperture value is only f/5.6, so the longer the focal length is used, the smaller the aperture.

In this case, should I use the long focal length (aperture to be smaller) or the big aperture (the focal length is short)? In fact, the use of that orientation should depend on the circumstances at that time (to be far or near.) In fact, both are also available.

A constant aperture lens allows you to use the largest aperture in that focal segment.

The photosensitive element also has an effect

To take a shallow depth of view, the photosensitive element can also have an effect-the more stool the photosensitive element is, the easier it is to take a shallow depth of view, so the Full-frame camera is more susceptible to background change than a APS-C/M43 camera.

I hope that you can make good use of the technique of shallow depth, do not often think that only the expensive lens to shoot AH. Let's try it today.
