Soft Focus Lens
=====================
[Concept]
Soft Focus
Also known as "soft-focus lens, soft lens, do not rely on the attachment of soft glasses or soft yarn soft conditions, the discharge of the soft effect of the soft function alone lens special photographic lens.
====================
[Sub class]
1 #, 2 #, 3 #
====================
[Structure]
A perspective in the light path of the lens, set up a main optical axis vertical porous metal film.
Subject light entering the lens, will produce diffusion through the hole in the sheet metal, and, eventually presented the effect of soft light in the image on the film plane.
2 soft mirror, made of transparent glass, the surface of the glass corrosion uneven light through the lens surface will be scattered, so that the outline of the subject to soften the contrast between the lower production
Born one kind of "soft" effect.
Corrosion by the photographic method, transparent mirror surface or two transparent laminated lenses, showing a diffuse role in a series of small grooves, circle or box-shaped graphics.
If the distribution of these graphics is very dense, very deep corrosion, the more weight the effect of the soft mirror to soften the image, and vice versa, graphics distribution survived sparse, corrosion survived shallow soften the image effect is the more light .
====================
[Soft effect
Strength of control, there are two
--------------
Adjust the lens aperture control
When the lens aperture to the minimum stalls, soft effect could be reduced to the weakest, this time, the photographer can be soft lens as ordinary camera lens.
--------------
2 head itself has the effect of soft control
This lens has a soft conditioning, the strength of soft effect is divided into multiple files, such as a "soft effect" soft effect "of the weak, soft effect" and "strong soft effect "and other gear for photographers choice.
====================
[For use]
(1) soften the image
(2) reduce the screen contrast
3 Adjust the picture tone, hue,
According to the creative intention to form a special picture effect, so that the camera screen is more interesting.
====================
[REC Mode]
A soft focus lens shooting There are many ways, but also when ordinary fixed focus lens is used, usually has three sections of soft focus effect adjustment.
The most usual way of shooting is to shun light shooting, but now the latter modify the software can easily achieve the same effect, so this way of shooting is not to explain.
(2) real soft focus lens when shooting in backlit light there will be proliferation effect
In addition, the spread of a backlit light time point is very beautiful, especially for the night view of lights shooting is more intense.
(3) because the reasons of the lens spherical aberration with a soft focus effect color performance will decline, contraction of the aperture can not improve.
4 the best performance of the soft focus lens shot is backlit, especially when photographing people suggested that the characters wear white clothes or hats (do not use flash).
5 figures and scenery with shooting, shooting in backlit control the focus after the former in, you can shoot out the fantastic visual effects.
====================
【Application】
A soft lens is widely used in portrait photography, cameras main role is to focus accurately under the premise, the subject of light through the hole on the sheet metal diffusion phenomena, weaken the camera lens being photo material detail "sharp characterization of the performance, in order to avoid the subject minor defects lens clearly recorded, the overall beauty of the subject.
Shot with it can help to hide some flaws in the characters face or skin, so that the characters become more smooth bewitching. Outdoors, use soft shots of, will enable the photo is filled with a mysterious, romantic colors.
(2) widely used in photography and post-production.
