Prime lenses are lenses that have a fixed focal length-they don't zoom. Good bokeh lenses also have a larger number of blades that make up its lens opening or its diaphragm. Fast lenses have maximum aperture of f/4.0, f/2.8, or wider. A fast lens is one that has a large aperture to achieve that shallow depth of field we talked about. Generally speaking, lenses that are fast, are prime lenses, and are telephoto, will give you the best bokeh. Now you want to know what's a good lens to use for getting nice bokeh. So, you know you'd like to get that soft, creamy look of attractive bokeh in some of your photos to contrast with the sharpness of your subject. You want to achieve a shallow depth of field with any points of light becoming soft circles in the background.

They include the maximum aperture you can use with the lens, the distances between the camera and subject and the background, the number of blades within the diaphragm of the lens, and the type of lens elements used in the construction of the lens. What creates bokeh? There are several factors. There is a very soft transition from white to blue in the background, with no distracting lines or shapes that illustrates the bokeh.

Additionally, there are free apps and paid apps that you can download to your phone for a few dollars. You can also use "Portrait Mode" or "Bokeh Mode" or certain iPhones and smartphones. Of the blur several different ways to see which you like the best on the same photograph. Gaussian blur is a filter that is commonly used in Photoshop, but there are several ways to get bokeh with Photoshop and Lightroom.Īdvantage of Gaussian blur is you can change the amount and direction
Diy bokeh lens software#
You can use software on your smart phone or on your computer. Yes, another way to get a somewhat artificial Bokeh effect is to add blur if you do your own photo editing. Digital cameras with full-frame sensors will give you the shallowest depth of field and also the best Bokeh effect. Very small sensors such as those in cell phones and compact point and shoot cameras give too large of a depth of field to get a very good Bokeh effect. In addition to how long a lens is (telephoto strength) and how wide it can open (maximum aperture), the third major factor in getting good bokeh and shallow depth of field is sensor size. There are several factors that affect bokeh. Understanding what is bokeh and the different ways to control it can improve your ability to turn a good photo into a great photo. The shape of the diaphragm and the number of diaphragm blades in the lens affects the shape of the bokeh highlights.
