Should I let my camera blend the HDR or submit the single HDR blended image to AutoHDR?

Don't let your camera blend it. Send the individual input brackets to AutoHDR — the AI replicates the hand-blending process that a human editor would do, which is more intricate and better-looking than your camera's automatic blend.

Why send unblended brackets

Camera-side HDR blending is simple averaging. AutoHDR's AI-driven blend is closer to a skilled human hand-blending the exposures together — better dynamic range, cleaner window pulls, more natural results.
