“How do I get a blurry background?”, asks a student.
OK… so if you want a blurred background, as in a portrait:
- Focus accurately (using one focus point?) on what should be sharp. The eye of your subject, for example.
Then, use some combination of:
- Get close to your subject.
- Zoom in on your subject.
- Use a longer rather than wider lens.
- Use a lens with a large maximum aperture, i.e. a low minimum “f-number”. (Most prime lenses and most pro lenses are like this).
- Use a low f-number
- Use “portrait mode” (which uses… a low f-number!).
- Have a distant background
And that’s how you do that. As my students at Sheridan College are learning this semester.
