defines the quality of the blurred lights presented in a photo.
Usually, this type of blur highlights the focused subject even more.
Producing nice bokeh involves creating a shallow depth of field.
Some tips of producing the "bokeh" effect:
1. Larger aperture works best, so use a low f-stop number like f1.4, f1.8 or f2.8. 2. Set your camera to aperture priority. 3. You would need to set the shutter
speed faster than 1/50 second. Any slower and you will find the
background lights getting blurred together, instead of rendering small
circles. If it’s too dark, increase the ISO level rather than the f-stop
number. 4. The closer you get to subject, the better. If you’re using a zoom lens, extend it to the longest focal length. 5. The further away the background, the better.
6. Ensure that the background is lit. Glowing lights like street lamps
and traffic lights work best. While a consistently lit background would
just create a regular blur. 7. If you don’t have a subject and want to create the bokeh effect with the night lights, manually focus your camera.
