How do you Bokeh?

[rateeg]

I just wanna know how you guys do effective bokeh?
I mean how the background to be extremely blur.
Thanks

I think what you are asking is "How do I achieve a shallow DOF (Depth of Focus)"

Here is an example from my collection.

Many factors will allow you to recreate this. A large aperture (low f/number), a large distance between your subject (the flower) and the background (the trees), a long focal length.

Try searching on this forum, there are countless threads that go into depth on this subject.

Wikipedia ...

In photography, bokeh (pronounced /bɒkɛ/[1]) is the blur,[2][1] or the aesthetic quality of the blur,[3][4][5] in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."[6] Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively

if i use 50mm lens, how do you achieve it effectively?
Thankw

This was already answered...

yep, but can't adjust the focal length since it's stuck to 50mm.

(look at the other two solutions)

thanks for the tips.
will try these.

Bokeh is what it is. Its an effect determined by the design of the lens. Depth of Field which causes more or less blur. If you want nicer Bokeh ( a descriptive term used for the actual blur created by the DOF ), you have to buy a different lens ( most likely a more expensive one ), if you simply want blur of any kind in the background, use as wide an aperture as possible, keep the subject as close to to the camera as possible, and the background as far away as possible.

 

[rateeg]

what about if the subject is far, can you still do the blur?

Why don't you go try it and find out?

Focal length ≠ Aperture...


If the subject is far, you can still do it - the background just has to be even farther.

Once you get too far though, it won't really matter - everything will effectively be at the same distance to the camera...

you'll get great bokeh with the 50 mm prime ....a quick google search landed me here you can find even more

If the subject is far away and you are using a long focal length ( 300mm ) you would get blur. Using long focal lengths creates a much shorter DOF.

yes and no... if your subject is far and standing right in front of the wall, you wont get much bokeh as the background is close to the subject.

- distance from subject to background (further = more bokeh)
- focal lenght (longer = more bokeh)
- aperture size (wider = more bokeh)

So for max bokeh, shooting a long focal range (say 200mm) with a wide aperture (say f/2.8) and have the subject stand further from the background
