What is soft light in photography? What is glare?

Soft light in photography generally refers to indirect light, such as cloudy days.

Hard light refers to direct light, such as a scene in the sun.

It can also be distinguished from the performance effect: soft light has no obvious shadow, while strong light has obvious shadow.

Brightening or darkening the color depends on the mixed color, which is similar to the effect of divergent spotlight on the image. If the mixed color (light source) is brighter than 50% gray, the image will become brighter as if it were dark. If the mixed color (light source) is darker than 50% gray, the image will be darker as if it were deepened. Painting with pure black or pure white will produce obviously darker or brighter areas, but it will not produce pure black or pure white.

Strong light refers to strong direct light. Under strong light, there are light receiving surface, backlight surface and shadow on the object, which is an effective effect to form the three-dimensional shape of the object; The brightness distance between the light receiving surface and the backlight surface of hard lighting is relatively large, that is, the inverse size of the scene can cause strong contrast between light and dark, which is suitable for expressing rough surface texture; This modeling effect makes the lifted object form a clear image in outline form. This light effect can achieve both "powerful" and "hard" artistic effects.
