    In 36mm x 24mm format (film or sensor) you will need at least a medium focal length lens of 85mm or longer with a taking aperture of f2.0 or f2.8. Any lens longer than 85mm and wide aperures will give you more unfocussed background known as bokeh. The quality of the unfocussed background or bokeh depends on the quality of your lens. Zeiss and Leitz lenses have excellent bokeh but they cost a fortune.

    normally play with the aperture. if you camera has aperture priority, use that mode. the wider the aperture the smaller DOF (Depth Of Field, where the area that focused in the picture, small DOF will have small area focus and the rest is blur) focal length also have effect on DOF (longer focal length = smaller DOF) distance to object also have effect on DOF (close to object = smaller DOF)

    as ae86trueno had mentioned, play around with your camera.
    go into manual mode if you have it. if you have it, try aperture priority.
    play around with the fx.x values on your camera. putting them to their lowest values will generally be a good place to start with your experimentation.

    I would just blur the photo in post-production. Photoshop allows you to do that fairly easily.

    even so, it doesn't look quite similar to the real one. lens bokeh can't be reproduced by using blur filters in any way!

    Hey dude....I was only trying to help out the post . . . calm down. Actually, yeah it can be done quite easily and effectively in photoshop and it is done by professionals all the time.

    just relax lookmomitsme! i was only showing my little point and i do agree with u. it can be done by professionals. but from an amateur point of view. to achieve that, i would think that's more than just using blur filters.
