In portrait pictures, you want to make the background as blurry and blurry as possible so that the people you photograph will appear clearly without being disturbed by messy elements in the background.
In other words, you are looking to create a little depth of field.
Depth of depth depends mainly on three factors:
1. The aperture
Large aperture gives a fuzzy background. We say it creates a little depth of field.
The easiest way is to set the camera to A / Off mode (aperture = aperture) and select the smallest number on the scale (eg 1.4, 2.8 or 4.0). You can also use manual setting or portrait mode if you have it on your camera.
The aperture values are often written with f / front (f / 1.4, f / 5.6, etc.), but your camera probably only has numbers.
Small numbers = large aperture, and large aperture gives little depth of field. Yes, it’s a bit backwards – but that’s the way it is. I often photograph myself on large apertures because it provides a nice, dusky and unclear background that does not interfere.
2. Focal length / lens
The focal length tells you what kind of lens you have and are set in millimeters. The lens of the camera can roughly be divided into three main categories :
- wide angle (short focal length, from about 10-35mm)
- normal (moderate focal length, from about 35-70mm)
- tele (long focal length, from about 70mm upwards).
The longer the focal length, the more blurry the background and background of the image will be.
Therefore, if you want the most ambiguous background, normal and telephoto optics are preferable to classic portraits. I often use 85mm for portraits. If you have a zoom lens, you can “zoom in completely” for maximum focal length.
3. Distance to subject and background
This is important! If you place the person at a great distance from the background, the background becomes more out of focus. If you also move closer to the person you are photographing, the background becomes even more blurry.
To get the most fuzzy background for your photos, just follow these three simple rules: use a large aperture, a long focal length (eg telephoto lens) and make sure the person you’re shooting is not very close to the background.
The focus should be in the eyes of the model. With little depth of field, it doesn’t take much to focus on errors. Therefore, take lots of pictures!
Learn to use the equipment you have before considering buying new, better and more expensive equipment. New, better and more expensive equipment is at least as difficult to learn to use.
It is not the background that is important in a portrait! Good communication with the people you photograph is alpha and omega.
