Canon Log Gamma and Wide DR Gamma Canon Log Gamma preserves shadow and highlight detail for maximum editing and grading in post-production without degrading image quality; contrast and sharpness are subdued with characteristics similar to negative film. Canon Log Gamma emphasizes rich gradients from mid-range to highlights and realizes 12-stops of Dynamic Range (DR). At ISO850, Canon Log Gamma enables 5.3 stops of latitude above optimal exposure (and 6.7 stops below), broadening the available dynamic range in color grading.
Wide DR Gamma is based on Rec. 709 and is optimized for monitor output or situations requiring less color grading in post-production. Wide DR Gamma exhibits high dynamic range, suppressing brightness while maintaining seamless gradations. A wide dynamic range of 800% preserves latitude for post-production work, but Wide DR Gamma is designed for perfect color "out-of-the-box."
