Comparison of RGB color bit depth in different image formats. JPEG supports 8-bit per channel (256 steps) resulting in 24-bit total color depth with approximately 16.7 million colors. HEIF enhances color representation with 10-bit per channel (1,024 steps), achieving 30-bit total color depth and about 1 billion colors. RAW format provides the highest color fidelity with 14-bit per channel (16,384 steps), enabling 42-bit total color depth and approximately 4.4 trillion colors. Each channel (R, G, B) box represents the respective bit depth and color steps, while the total values below show the cumulative color representation capabilities of each format. Some camera manufacturers also provide RAW formats supporting 16-bit per channel color depth, offering even greater color precision and dynamic range.
