The application of photography skill "depth of field" can be done in 5 minutes.

Photography has skill. How to take good-looking photos with the photographic equipment at hand? The following tips hope to help you understand the application of "depth of field" in 5 minutes and make better use of existing equipment to take beautiful photos!

(1) The aperture size has an influence on the depth of field.

Remember the following theory:

Large aperture = small aperture = blurred background/scene depth = taking a portrait (as a memory example only)

Small aperture = large value = clear background/depth of scene = shooting scene (same as above)

Examples of large aperture are f/ 1.4, f/ 1.8, f/2.8, etc.

Examples of small aperture are f/8, f/ 1 1, f/32, etc.

A large aperture can make the depth of field shallow. (Photographed by Tim Peters)

(The second point) The focal length has an effect on the depth of field.

Under the same aperture: the longer the focal length, the shallower the depth of field, so the portrait can be taken with 85-200mm (memory example).

(3) The distance of the background has an influence on the depth of field.

The farther the background is from the subject, the shallower the depth of field.

(fourth point) Can I take a shallow depth of field in automatic mode?

Although automatic mode can't adjust the aperture, you can try:

Turn on macro mode;

Shoot the camera as close as possible to the subject;

Find an angle to keep the background away from the subject.

Such photos should also have a shallow depth of field effect!

Using the macro mode of the camera, close to the subject, you can get a shallow depth of field effect.

(Fifth point) Is the range of depth of field the same before and after focusing?

It's different. Usually, the range of depth of field will be 1/3 before the focus and 2/3 after the focus, but the longer the focus, the closer the range.

(point 6) when do you need to use shallow depth of field?

Although the effect of shallow depth of field is beautiful, it is not casual. The following situations can be used:

Want to focus on the subject (such as taking portraits);

When the background is too messy (such as taking pictures in the street);

When I want to shoot a dreamy effect;

Creative photography, eg when self-made random patterns are taken.

Using shallow depth of field can produce dreamy effects.

(Point 7) When do we need to use depth of field?

When your aperture is small, the depth of field will become deeper. When we want to make all the photos clear, we will use the depth of field, which is commonly used in landscape photography or street photography.

When shooting scenery, you will use a deep depth of field to make the content of the photo clear.
