1. Highlighting Composition and Contrast: Black-and-white images allow viewers to focus on composition, lighting, and contrast without being influenced by colors.
2. Timeless Aesthetic: Black and white evoke a sense of nostalgia and timelessness, often bringing out a classic feel in portraits, landscapes, and architectural shots.
3. File Size Reduction: Converting to black and white can reduce file size since it eliminates color data. This can be beneficial for web use and storage optimization.
