What Is HDR, Anyway?

a year ago

HDR in photography can mean two different things: 'HDR mode' introduced in iPhone cameras in 2010 and HDR screens that display more vibrant images.
Dynamic range refers to the difference between the darkest and brightest parts of a scene, which cameras and screens struggle to capture or display accurately.
Solution 1: 'HDR Mode' involves taking multiple photos at different exposures and combining them into one image, with tone mapping to fit SDR screens.
Early HDR algorithms required manual adjustments, leading to over-processed images, but modern phone cameras automate this process.
Some users prefer turning off AI-driven HDR features like Smart HDR and Deep Fusion due to artifacts and loss of detail in moving subjects.
Solution 2: Genuine HDR displays offer higher dynamic range, but adoption is slow due to cost, taste preferences, and compatibility issues.
HDR content can be too bright or garish, leading some to disable it, and browser support for HDR photos is still limited.
Solution 3: Some photographers prefer SDR for its aesthetic, as hyper-realistic HDR can sometimes be less engaging or flattering.
Halide's approach includes opt-in, single-shot tone mapping, giving photographers control over dynamic range adjustments.
The future of photography may involve a balance between SDR and HDR, with choices left to the artist rather than algorithms.
