The effect of star rays in photos

When shooting a bright light source into the frame, you can get an interesting effect with the rays of light. This effect is usually called Star Effect.

This effect is very easy to get. To do this, simply remove the bright light source on the closed aperture. How much the aperture has to be closed depends on the lens on which the image is being taken. Each lens has a certain number F, which results in a pronounced effect with the rays. For the most part, when using digital cameras that do not have a mechanical diaphragm control device with aperture blades, the effect with the rays will not work.True, even if you catch a bright light source in the frame, it does not have to turn into a star with outgoing rays. For example, in the photo above, the sun was photographed at the closed F / 22 aperture, but at the same time there was no star effect. It is in this case that the reason for the presence of clouds that soften the hard light. For sure to get a pronounced effect of the star’s rays in the photo, you need to shoot bright light sources with the so-called “spot” or “hard light”.

The example above shows a photograph with a pronounced effect of the rays of a star from the lanterns.

An interesting fact is that the number of rays emanating from light sources is equal to the number of lens aperture petals, if the lens has a pair number, and double the number of aperture blades, if there is an unpaired quantity. For example, in the photo below, the sun has 14 rays of a star, while the photograph was taken with a Tamron AF 17-50mm f / 2.8 XR Di II LD lens which has 7 aperture blades.

If the aperture on the lens is not closed, then such an effect will not work, and a bright source in the frame may spread in the form of a bright sphere or a sphere with oblong “tails”.

When creating such an effect, parasitic flare, glare, and solar hare often appear in the frame. Moreover, the extra artifacts can be enhanced by using simple cheap protective filters.

Sometimes the effect with the rays is superfluous and should be avoided, as it poorly conveys the real atmosphere in the photo. After all, the human eye does not see any rays, and when photographing, they can turn out.

On sale you can find special Star Filters (filters to create a star effect), which multiply the possibility of receiving rays in the frame. With this filter, you can create a star with a strictly defined number of rays, their intensity and different types.
