Shutter speed does not directly affect bokeh. For great bokeh photography, you need to choose large apertures. Larger aperture sizes also mean lower depth of field, as that is the area that remains in sharp focus.
When the bokeh effect is created intentionally, it turns out to be a powerful weapon in your artistic arsenal. Bokeh refers to the optical effect that the photographer creates when the camera renders an out-of-focus background through the lens.
After reading this article, you will know all there is to know about bokeh. What affects bokeh? How to increase and reduce your bokeh effect? And what does shutter speed affect?
Let’s get right to it.
Here are some of the things that affect bokeh:
- To achieve bokeh in an image, you will need a fast lens – the faster, the better. You will at least need an f/2.8 aperture if you want a visible bokeh.
- The lens is used to determine the size of the visible bokeh. If your lens has more circular-shaped blades, then your bokeh will have rounder, softer orbs, whereas a lens that is more hexagonal will reflect that shape in the bokeh highlights.
- Shooting in aperture priority mode or manual mode affects bokeh. Manual mode allows you to choose both your aperture and shutter speed. Aperture priority mode allows you to choose the f/stop while the camera chooses the appropriate shutter speed.
To increase the bokeh effect in your photo, increase the distance between your subject and the background. You can do this by decreasing the distance between the camera and the subject.
The lower your depth of field will be or further the background is, the more out of focus it will be. If you want larger orbs of light, you will need to place the subject a little bit close to the light source. If you want smaller orbs of light, put more distance between the subject and the background.
You can use a backlight or a side light or a hair light to create the highlights that would be hitting the background. This will show more visible bokeh and the effect will be pleasing to the eye.
Close-up and macro images of flowers and other objects in nature show off bokeh in an image very well. Another extreme example of bokeh is photographing a grouping of holiday lights or other highly reflective objects.
Christmas lights are an easy way to achieve that “out of focus” blur and add a good bokeh to an image any time of the year. Other than the Christmas lights, the cityscape at night or the evening sun filtering through some trees would give the same effect.
To reduce the bokeh effect in sufficient lighting, bump up the f/stop to a higher value and your bokeh effect will decrease.
Other factors that will reduce your bokeh effect are –
- Insufficient light source.
- If you position your subject very close to the light source, or directly in front of the background or leaning up against it, it will reduce the bokeh effect.
- Don’t set your aperture settings to a wide aperture. Choose a high f-number to reduce the bokeh effect on your photo.
Shutter speed is responsible for two main things – changing the brightness of the photo and creating dramatic effects by either freezing action or blurring motion.
Longer shutter speeds or slow shutter speeds produce motion blur. This effect is mainly used for the advertisement of cars and motorbikes where a sense of speed and motion is communicated by blurring the moving vehicle.
Slow shutter speeds are also used to photograph the milky way, other objects at night, and dim environments with the help of a tripod, rivers and waterfalls.
Faster shutter speeds freeze motion. You can eliminate motion even from fast-moving objects, like birds in flight.
The other important effect of shutter speed is exposure. If you use a longer shutter speed, the resulting photo will be quite bright. If you use a faster shutter speed, the resulting photo will be darker.
