nikon d90 camera with lens image
I'm using the kit lens and nikon D90 camera.
A photographer was able to get a bokeh effect with the settings:
ISO 800
f5.6 1/500 shutter speed
i used those settings and zoomed in to take a photo, but I still can't get a bokeh background? Why?
Answer
First, bokeh is not an effect. Bokeh is a Japanese word that loosely translates to "pleasing blur" - a description of the quality of the out of focus highlights in the background. The design and number of the movable blades that make up the diaphragm inside the lens determines the quality of the bokeh.
To achieve a good background blur requires understanding Depth of Field (DOF) and how to control it. This site will help: http://www.dofmaster.com/dofjs.html DOF is a product of 3 factors:
1) The focal length used.
2) The f-stop used.
3) The subject distance.
NOTE: ISO and shutter speed have NOTHING to do with DOF.
By using the DOF Calculator on the site you can compute DOF for any combination of the 3 factors imaginable. Using your camera and the 105mm focal length here are some examples of your DOF at 5'-0'', 10'-0'' and 15'-0''.
105mm @ f5.6 focused on a subject at 5'-0'' DOF will be from 4'-11'' to 5'-1". Anything from 1" in front of your subject to 1" behind it will be in focus.
105mm @ f5.6 focused on a subject at 10'-0'' DOF will be from 9'-9'' to 10'-4''. Anything from 3" in front of your subject to 4" behind it will be in focus.
105mm @ f5.6 focused on a subject at 15'-0'' DOF will be from 14'-4'' to 15'-8''. Anything from 8" in front of your subject to 8" behind it will be in focus.
If your background in any of the above examples is a foot or more behind your subject it should be very out of focus. However, it must be a background with highlights. If its a solid color background then it won't have any bokeh.
