10bitperchannel

10bitperchannel refers to digital color data where each of the primary image channels—red, green, and blue—is represented with 10 bits of precision. This provides 1,024 distinct values per channel and about 1 billion total color values per pixel in RGB color spaces. The term is commonly described as 10-bit color or 30-bit color, highlighting the per-channel depth rather than total pixel depth.

The main benefit of 10-bit per channel color is smoother tonal transitions. With more levels available, gradients—such as skies and skin tones—are less prone to banding and quantization artifacts, especially in high dynamic range (HDR) contexts. In professional workflows, the extra precision supports color grading, compositing, and HDR encoding, allowing adjustments with reduced loss of detail.

Formats and workflows: 10-bit color is supported in modern video pipelines and HDR formats, including HDR10 and related encoding paths. In still photography and professional imaging, 10-bit or higher data can be stored within RAW workflows and certain high-bit-depth formats used in TIFF or EXR pipelines. Many consumer formats remain 8-bit per channel, but professional and broadcast pipelines increasingly adopt 10-bit or higher at intermediate stages and final delivery.

Practical considerations: Realizing the benefits requires compatible hardware and software, including 10-bit-capable displays, graphics cards, and color-management workflows. Working in linear color spaces with high-bit-depth intermediates helps preserve precision. When outputting to lower bit depths, dithering or perceptual quantization can help mitigate banding.

Limitations: Not all devices can display true 10-bit color; many consumer screens simulate depth with processing. Higher bit depth also increases data size and bandwidth, and end-to-end preservation depends on an intact, properly calibrated pipeline.
