Bit depth for viewing
Bit depth for viewing
Images with more than 24 bits per pixel are excessive for just viewing, as the human eye can only discern a limited number of colors.
Bit depth and post-processing
Bit depth and post-processing
Images with more than 24 bits per pixel are beneficial for post-processing, keeping detail better.
Posterization effect
Posterization effect
Images with fewer than 8 bits per color channel can show visible color gradations/steps (called posterization).

Study Notes
Bit Depth and Image Quality
- Human vision is limited to approximately 10 million colors.
- 24 bits per pixel (bpp) is sufficient for visual display.
- Higher bit depth (above 24 bpp) is beneficial for post-processing.
- Images with fewer than 8 bits per color channel can exhibit posterization (undesirable color banding).
- JPEG files typically use 8 bits per channel.
- TIFF files can use 16 bits per channel.
