Contrast is a fundamental element in photography that enhances the visual impact of an image. It is the degree of difference between the darkest and lightest parts of a photo. High contrast images have sharp distinctions between light and shadow, creating a bold and striking effect. On the other hand, low contrast photos have a more subtle transition between tones, resulting in a softer look. Understanding and manipulating contrast is crucial in product photography as it can influence how textures, shapes, and colors appear in the final image.
