how do i take pictures where its directed to one object and the background is entirely blurry?

Answer 1

use a F-stop lower than 5.6

I dont know how much you know about photography, but if you are used to using the manual setting on a camera then all you need to do is adjust your F-stop so that you are using an apature like 2.8, 3.2 and so on up to 5.6. The smaller the number the more blurry the background will be.


The second answer from "Cash..." is a trick to imitate the technique i laid out. If your lens does not have an apature that i listed you can zoom all the way in with a large zoom lens and it will do a OK job of giving you blur in the background.

Answer 2

A lower aperture setting would decrease the depth of field (or how much of the frame is in focus). Since f-stops are quantified in fractions, the smaller number = bigger aperture opening allowing for more light and a faster shutter speed. Oppositely, a higher aperture setting = smaller aperture hole, which allows for less light, needing a slower shutter speed, but allowing for a greater depth of field.

Answer 3

The Jokker has it down to the simplified science. Focal length has some effect but the aperture effects it the most. f1.0=nose in focus but eye out of focus. f64 nose in focus and moon in focus ;)

Answer 4

I recommend a 35mm - 50mm camera. The higher the number, the larger the amount of blur contrast you will get. You can focus on one object and have the other distant object blur easily when done manually.

Answer 5

you can use selective focus or narrow depth of field by using a combination of a telephoto lens and a small aperture.
happy shooting!!

Answer 6

using the zoom at the same time as exposing the frame.. manual zooming works. mechanical zoom is to slow.

if you can't get the hang of it, try an airbrush in your dark room. you can create the same effect that way.

Answer 7

a low f-stop, a macro lens does it nicely.
