How can I achieve a soft background blur in my portraits using a prime lens?
Asked on Feb 18, 2026
Answer
Achieving a soft background blur, or bokeh, in portraits is often accomplished by using a prime lens with a wide aperture. This technique helps isolate the subject from the background, creating a pleasing aesthetic that draws attention to the subject's features.
<!-- BEGIN COPY / PASTE -->
Lens: Use a prime lens with a wide aperture (e.g., 50mm f/1.8 or 85mm f/1.4).
Aperture: Set the aperture to a low f-stop number (e.g., f/1.8, f/2.0).
Distance: Position the subject closer to the camera and further from the background.
Focus: Ensure the focus is precisely on the subject's eyes for sharpness.

- Prime lenses are preferred for their sharpness and ability to open up to wide apertures.
- Consider the distance between the subject and the background; the greater the distance, the softer the blur.
- Experiment with different focal lengths to see how they affect the depth of field and bokeh quality.
- Lighting can also impact the appearance of bokeh; soft lighting often enhances the effect.
