Political polarization

Circularly polarizedlight

If you want to change the depth of field when the picture is already taken, post-shooting editing sometimes can help. But try different combinations and take as many pictures as you can, it will greatly save your time.

To tell briefly – in all the cases when a photographer wants to draw the viewers’ attention to the central figure, not to the distracting background.

The wider aperture is, the shallower focus you’ll have. Just a small reminder: aperture is defined by an F-stop number. Small numbers stand for wide apertures, which let a lot of light in, and vice versa. To achieve shallow DoF you’ll need to set it on F/2.5 or even less.

Degree of polarization

To get the background blurred you must leave some space between it and the object you shoot, so that the photo has distinct “layers”. You won’t be able to create such an effect with an object leaning on the background.

In order not to overexpose your picture, you should shoot with a fast shutter speed. Or you can just turn on aperture priority mode that will adjust all the settings according to the aperture you’ve selected.

Definition noun Light in which electromagnetic vibrations oscillate repeatedly in only one direction perpendicular to the direction of propagation. Supplement Light polarization is a property of light waves that depicts the direction of their oscillations. A polarized light vibrates or oscillates in only one direction. This is in contrast to a nonpolarized light that vibrates in many directions. A polarized light may be plane-polarized, circularly polarized or elliptical-polarized light based on the net direction of the vibrations. Many animals are able to perceive and use certain forms of polarized light. For instance, insects use plane-polarized light for navigational purposes. A naked human eye is not very sensitive to polarized light but with practice, or with the use of a polarizer, humans can then perceive a polarized light such as the Haidinger’s brush phenomenon.

If your lens doesn’t allow a wide aperture, you can distance from the object of shooting and then zoom in. Doing this will create a better shallow Depth of Field effect.

Depth of Field (DoF) is a term that defines how many “layers” of the picture are sharp. With the deep DoF you’ll be able to see the finest details of the foreground as well as the background, shallow depth of field photos keep only a foreground focused, while the rest is blurred.

Elliptical polarization

Circular polarization

The meaning of this term in simple words is “the distance between a lens and a sensor”. The longer focal length is — the shallower DoF you get. So, if you can, try out a zoom or a telephoto lens for a DSLR camera, it will increase this parameter and improve your experience in general. In case of iPhone or Android phones, you can use a digital zoom, there will be the same effect.

You may also step a little forward and get closer to your model, then the cam will focus on it and the background will get hazed.
