Considering how so many people are openly sharing their knowledge about photography, it’s no wonder why there are a lot of photography techniques to make your pictures look better.
Although a professional photographer has several techniques up his sleeve, one that’s commonly used is the depth of field (DOF). Because of how dramatic the effects of depth of field are in your photo, mastering it will take your photography skill a notch higher.
But before we even start discussing about DOF, let’s get to its description first so we’d all be on the same page.
“The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.”
What does that definition mean to you? It simply means that you need to learn how make your image background super blurry so you can take cool photography! But there is a lot more to it than that. If you can master DOF then you can take creative photographs just like a pro. But to become a true master is an art.
Let’s now take a look at the things that you need to know about DOF:
1.) Learning about aperture is a must
The Aperture of a camera refers to the lens diaphragm size that regulates the amount of light that’s allowed to pass into the camera at the moment of exposure. It controls your depth of field.
The larger your aperture is, the shallower your depth of field becomes. Conversely, the smaller your aperture is, the deeper depth of field you’ll get causing more focus on the entire image. The aperture is measured by using a scale of f-stops.
Since adjusting the aperture plays a key role when controlling your depth of field, having a camera with an aperture of full manual mode is highly advisable. This allows you more control by making micro level changes on your depth of field.
2.) The background and positioning matters
Regardless of how large your aperture is, if there is no object in your target image’s background, then you won’t be able to convey its depth of field effectively.
Having said that, aside from choosing the right aperture, be sure to position yourself accordingly so as to make the background visible when capturing photos.
The DOF also plays a key role in softening the background or blending your target object to the background. Through the use of depth of field, even if your background looks busy, you can still soften it by making the whole image cohesive.
3.) Zooming in and out affects the depth of field
Now if you’re in a hurry, instead of adjusting your aperture to get the right figures, you can instead use the zoom in or zoom out feature of your camera.
Zoom in = Lowers/minimizes the depth of field
Zoom out = Increase/maximize the depth of field
