Viewer Comment | Digital Foundry Channel In a recent Digital Foundry episode, during a discussion of a Wccftech article profiling graphics programmer Filippo Tarpini, host Oliver Mackenzie made a staggering number of questionable, misleading, or inaccurate statements. We correct the record. “High brightness displays can display HDR and SDR signals.” False. Only HDR displays can properly... Continue Reading →
The Top-Down Approach
Step #1 in HDR grading is defining the project’s ‘speed limit’ and highlight roll-off. Highlights dictate perceptual hierarchy. Shadows are subordinate. SDR-centric grading cripples HDR’s DNA. Start at the top. 1. What does setting a speed limit mean? Setting a speed limit means defining your target peak brightness (in nits) and highlight roll-off philosophy early... Continue Reading →
Highlights Aren’t Islands
Sony European Imaging Ambassador Alister Chapman uses his platform to promote categorically false claims about HDR: “It's only when you have specular highlights and direct light sources in the scene that are brighter than diffuse white that any differences start to become apparent. The entire image doesn't change, only these highlights do…” - Alister Chapman,... Continue Reading →
The HDR Misinformation Field Guide
The flowchart above maps the self-reinforcing system of reactionary HDR pathologies. The following sections define and dismantle each weapon in this arsenal. The Reactionary Mindset A reactionary position isn’t simply about preferring old tools: it’s about idealizing the past, viewing change as a detriment and moralizing technology. Direct Quote: “…the things that are actually different... Continue Reading →
The Foundation of Sky’s Technical Specification (Or Why 100 Nits Is Not HDR)
“The only line that can be drawn objectively is SDR’s 100 nits. Anything above that in principle is HDR.” Yoeri Geutskens, “We Need to Talk About HDR”. FlatpanelsHD (Oct. 2020) “It is perfectly acceptable to deliver scenes or projects at 100 nits or less in an HDR delivery.” Kevin Shaw, CSI, LinkedIn comment (Nov. 2025)... Continue Reading →
Sky’s Got A Clause For That
Sky UK's Technical Specification for Delivery of Content represents a rigorous, policy-driven approach to HDR that directly addresses the epidemic of “HDR in name only." The specification is unique in tying technical delivery requirements to creative intent and perceptual impact—a bond other streamers’ specs omit. A strict policy on paper doesn’t guarantee perfect compliance in... Continue Reading →
Sony Ambassador Alister Chapman’s HDR Claims Debunked, Part II
Sony European Imaging Ambassador Alister Chapman uses his platform to promote categorically false claims about HDR. We break them down using the international standards, colorist testimonials, research data, and studio policies. Industry standards, studios and professionals reject the simplistic “HDR = Brighter + More Colorful” claim. The “Brighter, More Colorful” Fallacy QUOTE: “When the first... Continue Reading →
Sony Ambassador Alister Chapman’s HDR Claims Debunked, Part I
Sony European Imaging Ambassador Alister Chapman uses his platform to promote categorically false claims about HDR. We dismantle them one-by-one using the standards themselves. The Data Efficiency Argument QUOTE: “PQ is very wasteful of data as it's designed around theoretical 10,000 Nit displays whereas BT1886 is designed for displays that actually exist.” — Alister Chapman...
