Many beginners often ask, how to make the background blur/bokeh when an image is a portrait? Actually how easy, and no less than three steps. Previously, you need a digital SLR camera, because it has a large sensor DSLR camera and you can replace it with a portrait lens. However, you can try using a compact camera even though the results are less than the maximum.
Step One: Set your zoom to the maximum point
For example, if you have a lens 18-55m, then set your lens to 55mm zoom. If you have any telephoto zoom lens, such as 55-250mm, this is even better. Use of this lens and zoom lens set to 85mm to 135mm you. Focal range is ideal for portrait photos.
Step Two: Position your model as far as possible from the background
The farther the distance between the background with the model than the distance to the camera model, the more blur the background of the camera.
Step Three: Set the aperture / aperture of your lens as big as possible
The larger the aperture the more blurry the background, when you have 18-55mm f/3.5-5.6 lens. So, set your aperture to f/5.6 (this is the maximum aperture at 55mm focal range.
If you are not satisfied with the results of 18-55mm lens, I recommend to buy the 50mm f/1.8 or 85mm f/1.8. Although the lens can not zoom, but very large maximum aperture, making it more suitable for portrait photos.
