How does increasing color depth affect an image?

Increasing color depth refers to the number of bits used to represent the color of each pixel in an image. When the color depth is increased, more bits are allocated to each pixel, which allows for a greater number of possible colors to be represented. For example, an image with a color depth of 8 bits can display 256 colors, while one with 24 bits can display over 16 million colors. This increase in available colors enhances the image's detail and nuance, enabling it to portray gradients and subtle variations more effectively.

Higher color depth is especially important in images where color fidelity is essential, such as photographs or detailed graphics, as it helps to avoid banding and allows for smoother transitions between colors. This capability is fundamental in ensuring that the visual presentation is rich and vibrant, which improves the overall quality of the image.
