Hey B&H viewers today we're going to talk about creating shallow depth of field with

Bokeh. It's the aesthetic quality of the blur or out-of-focus areas produced by a lens.

Now before you can make bokeh, you need to produce a shallow depth of field.

1. Put some distance between the subject and the background.

The greater this distance, the greater the differentiation between what's in and out

Aperture often expressed in f-stops determines the depth of field in your photos.

The smaller the number, the larger the whole that lets light into your camera.

Larger apertures will give you a shallower depth of field; opening the doorway to all

Different lenses offer different aperture values.

To create shallow depth of field, you'll want something with largest aperture possible.

Wide angle lenses can work, but longer focal lengths add compression — an element that's

incredibly useful in separating in focus subjects from out of focus areas.

4. Sensor size. Another important consideration.

While shallow depth of field is possible with any size sensor, the available lenses, working

distance from subjects, and overall rendering are significantly affected by sensor size.

Chose a background that lends itself to being out of focus in an interesting way.

Lights are always fun because they take on interesting shapes.

Shoot through a doorframe, compose with flowers in the foreground.

Remember, shallow depth of field isn't limited to showing off an out of focus background.

7. Use less distance between yourself and the subject.

By moving closer, you'll accentuate the details of your subject and add more nuance

Calling it good or bad is completely subjective.

But there's a few things to look out for.

If you fancy harsh, choppy bokeh select a lens with fewer aperture blades.

The look here is blunt, crude and incredibly literal.

For a softer more organic look, consider larger aperture lenses with rounded blades.

This shapes the bokeh into spheres or delicate ovals.

And if you want the softest most nuanced bokeh out there, try an apodization lens.

If you'd like to know more about apodization lenses, let us know in the comments.

These are some of my favorite types of lenses for portraiture.

Essentially there's an extra element included in the optical formula for smoothing the edge
