By changing the depth of field, you can maximize the expressiveness of your photo and make the desired subject stand out. And the competent use of this opportunity is one of the hallmarks of a photographer's skill.
Instructions
Step 1
Select the subject to be highlighted to be highlighted. Typically, portraits require the sharpest possible image of a person against a blurred background, while landscape photography requires an infinite depth of field, when both the nearest tree and the forest in the distance are equally clearly visible.
Step 2
If you need to achieve a minimum depth of field, that is, to highlight any subject against a blurred background, try to get as close to it as possible. At the same time, move the object itself away from the background as far as possible.
Step 3
If your camera has the ability to adjust the aperture position, set the priority mode and decrease it to 3, 5 or 2, 8. The aperture value should be indicated in the corner of the frame or next to the image in the viewfinder.
Step 4
Many cameras have a Macro or Portrait mode, use these to set the minimum depth of field. In this case, the camera itself will adjust the aperture and focal length of the lens, you just need to get close enough to the subject.
Step 5
On the other hand, if you want to achieve the maximum depth of field so that all objects in the photo, even distant ones, are seen equally clearly, set the aperture priority mode and increase its value to maximum. In addition, the "Landscape" mode provided on many devices can help you with this.
Step 6
Try to stand so that all objects are far enough away from you, no closer than 10 meters. Check the obtained depth of field in the viewfinder, if you have a DSLR, you can roughly estimate the change in sharpness with changes in distance and aperture values.
Step 7
If your camera has a good zoom, use it to change the depth of field. For shallow depths, move farther and zoom in on the subject to increase the focal length. If you need to achieve maximum depth of field, move the lens to the “wide angle” position and move closer to the subject.
