What is the reflection area of light in photography?

The reflection area is often said, for example, landscape photography, the position of lights, and corresponding places, such as walls or Beijing, can all use light to shine on these reflectors and reflect the light to the object itself.

This is much softer than direct lighting, such as taking portraits outside and reflecting plates.

Landscape photography: both reflector and soft light get soft light through reflection. Sometimes you have to find a good reflection point when shooting different things: so the reflection area should be used frequently.

The light is beautiful and the shadow is bright, which means: the front light shows color, the side light shows texture, and the backlight realizes outline.
