What are the best photography aperture tips for creating beautiful background blur?
|
I specialize in portrait photography and I'm always looking for better ways to use aperture creatively. There are so many photography aperture tips out there, but I want to focus specifically on creating that beautiful bokeh effect that makes subjects pop.
I know that wider apertures (like f/1.8 or f/2.8) create more background blur, but there's more to it than just cranking the aperture wide open. Distance from subject, focal length, and background distance all play a role too.
What are your favorite photography aperture tips for achieving professional looking background separation? Do you have any tricks for when you're working with slower lenses that don't open as wide?
For beautiful background blur, distance is just as important as aperture. One of my favorite photography aperture tips: get close to your subject and have them far from the background. The closer you are to your subject and the farther the background is, the more blur you'll get, even with smaller apertures.
Also, longer focal lengths create more background compression and blur. A 85mm at f/2.8 will give you more blur than a 35mm at f/2.8, all else being equal. So if you're struggling with a lens that doesn't open very wide, try using a longer focal length.
When working with slower lenses, one photography aperture tip is to pay attention to background complexity. A busy, detailed background will look messy even with some blur, while a simple, distant background will look creamy even at smaller apertures like f/5.6.
Also, the quality of bokeh matters. Some lenses have harsh, nervous bokeh while others have smooth, creamy bokeh. This is often more important than just how much blur there is. Look for lenses with rounded aperture blades for nicer out of focus highlights.
Here's a photography aperture tip for group portraits: don't shoot wide open! If you have multiple people at different distances from the camera, you need enough depth of field to keep everyone in focus. I usually shoot groups at f/5.6 or f/8, depending on how they're arranged.
For single subjects, I love shooting wide open (f/1.4 to f/2.8) but I'm careful about focus. At those apertures, focus has to be perfect because the depth of field is so shallow. I often use single point AF and focus on the eye closest to the camera.
One creative photography aperture tip: use foreground elements to create depth. Instead of just blurring the background, include some out of focus foreground elements too. This creates a more three dimensional look.
Also, remember that aperture affects more than just background blur. It affects lens sharpness (most lenses are sharpest around f/5.6 to f/8), diffraction (gets worse at very small apertures like f/16+), and starburst effects with point light sources at small apertures.
For landscape photographers, here's a different photography aperture tip: usually you want everything in focus, so you'll be shooting at f/8 to f/16. But be aware of diffraction at small apertures. There's a sweet spot where you have enough depth of field without losing too much sharpness to diffraction.
Use hyperfocal distance focusing for maximum sharpness from foreground to background. There are apps that calculate this for you based on your camera, lens, and aperture.
