Helio's style engine now ships with five distinct B&W looks — Pure, Hard Contrast, Reportage 400, Nocturne 3200, and Chroma 400 — each driven by zone-adaptive ML models for richer tones and authentic grain. The camera also gets a redesigned Style picker that combines look selection and grain controls into one screen, with visual previews of each grain texture and an optional Custom mode for fine-tuned size, contrast, and tonal response.
