Side lighting creates a sense of depth and texture by highlighting the contours and details of the subject. This is because the light source is positioned at an angle to the subject, rather than directly in front of it.

Side lighting is typically characterized by strong shadows, increased depth and texture, and a dramatic mood. Soft, diffused light is not a common characteristic of side lighting.

Side lighting often creates a mysterious, dramatic mood in an image. This is because the strong shadows and highlights created by side lighting can add a sense of intrigue and suspense.

A landscape photo taken at sunset is a good example of side lighting because the sun is positioned at an angle to the landscape, creating strong shadows and highlights that add depth and texture to the scene.

Early morning or late afternoon is the best time of day to use side lighting in photography because the sun is lower in the sky and positioned at an angle to the subject, creating strong shadows and highlights that add depth and texture.

All of the above techniques can be used to reduce the harshness of side lighting. Using a diffuser or scrim can help to soften the light, positioning the subject in the shade can help to reduce the amount of direct light hitting the subject, and using a fill light can help to fill in the shadows and create a more even exposure.

The primary advantage of using side lighting in photography is that it adds depth and texture to the subject. This is because the light source is positioned at an angle to the subject, rather than directly in front of it, which creates strong shadows and highlights that emphasize the contours and details of the subject.

Side lighting is not commonly used in still life photography because it can create strong shadows and highlights that can be distracting and detract from the subject. Other genres of photography, such as portrait, landscape, and product photography, often use side lighting to add depth and texture to the subject.

The effect of side lighting on the color of a subject depends on the angle of the light. If the light is positioned at a shallow angle to the subject, it can create strong shadows and highlights that can make the colors appear more saturated. If the light is positioned at a steeper angle, it can create a more even distribution of light and make the colors appear more desaturated.

The best way to learn how to use side lighting effectively in photography is to read books and articles about side lighting, watch tutorials and videos about side lighting, and practice using side lighting in different situations. This will help you to understand the principles of side lighting and how to use it to create different effects in your images.
