How do you take a Portrait shot with the background blown out of focus?

Question

I would like to take a few portrait photographs in different enviroments...one inside a building, one outside in the sun and one in the shade, but i would like the backgrounds to be out of focus. Is the key in the apperture? Thank you!

Answer 1

The aperture is the key, you wright; keep the maximum aperture on your camera and use a telephoto lens for your camera.
Remember, as the aperture gets wider, the shutter speed increases to mantain the proper exposure.
If outside you can not get wide enough, try lower ISO or use a ND filter (Neutral Density) 2X or 4X.

Answer 2

try to open the diaphragm in less than 11 and adjust the light with the speed of obturation and depending on how much light there is... i
n doing so you could also see on the lens that there is another mark that tells you where is going to be the "in focus" of the picture... is a line of numbers like this " 11, 8, 5.6, 8, 11" and it's fixed, can not be rotated. once you've seen it:

1.- focus the object
2.- set the diaphragm below 11
3.- go to the distance line on the lens (the one that says "1ft, 2ft, ... infinite") and check what's between the 11's of the fixed line, all that will be in focus, everything outside the 11's (if you picked that diaphragm aperture) will be out of focus...

Answer 3

Yes, you're right. Open the aperture right up and/or use a longer lens. Remember to focus on the eyes!

Answer 4

keep the distance between ur model and the background as much as u can...2nd use a focal length more than 80mm nd 3rd use a aperture f4 or more than this like f2.8 or f1.4 n u get a blurred outof focus background b it indoors or outdoors

Answer 5

Focus perfect on your subject and
minimise the depth of field by large
apperture say f2.

Answer 6

open your aperture to f2, if you don't have a long lens then make sure the person is close to the camera.

Answer 7

make your aperature setting huge, like 2. something or 5. something, that will do it
