How to adjust the white soft lens in portrait photography?

1, focus adjustment. The longer the focal length of the lens used, the stronger the softening effect. For filters of types (a) and (b), choose (a) for slight effect and (b) for strong effect.

2. Adjust the background brightness. The higher the contrast of the subject, the more effective the softening effect, the darker the background, and the highlight produced by the softening filter naturally softens, adding atmosphere to the work. The background is brighter than the main body, so it is difficult to feel the effect.

3. Dimming direction. The soft focus effect will change according to the direction of light and the position between the subjects. The softening effect is increasing in the order of front light, half backlight and backlight. Backlight is the sun, which will lead to overexposure. Find a composition that blocks the sun with people or trees. Soften the light leaking from the periphery of the subject with a soft light filter to obtain the effect of being wrapped by light. Using a weak soft light filter will reduce the contrast when backlighting.

4. Adjust the aperture. Even if the aperture value is changed, the strength of the softening effect will not change. In addition to adjusting the aperture, the background blur should be increased, and the telephoto lens should be used as close as possible to the subject to keep the distance between the subject and the background.

5. Change the white balance. Changing the white balance can enhance the softening effect and achieve a dreamy and nostalgic atmosphere. Create a dreamy or fairy-tale world view by setting the white balance to fluorescent light or lowering the camera color temperature to make it blue. Setting the white balance as a shadow or increasing the color temperature value to give it amber will get a nostalgic atmosphere.
