What characteristic does the ProPhoto RGB color space have compared to camera colors?

1. Smaller gamut

2. Equal gamut

3. Larger gamut

4. Limited gamut

The correct answer is: Larger gamut

The ProPhoto RGB color space is known for its extensive color gamut, which means it can represent a wider range of colors compared to many common camera color spaces, such as sRGB or Adobe RGB. This broader gamut enables photographers to capture more vibrant and saturated colors, including subtle differences in hues that may not be achievable in smaller color spaces. Since many high-end digital cameras can capture colors that fall within or beyond the Adobe RGB space, ProPhoto RGB is advantageous for preserving the full spectrum of colors that these cameras are capable of capturing during the image-making process. This makes it ideal for workflows that require high fidelity in color representation, especially in professional photography and print production. While other color spaces may become limited when reproducing colors that fall outside their designated ranges, ProPhoto RGB's larger gamut allows for a richer color depth, ultimately providing photographers with the flexibility to manipulate their images without sacrificing color quality.
