How astra renders it
Not a colour overlay. Each stock has its own tone curve, a channel-mixing matrix for crosstalk between layers, halation modelled as a bloom off the film backing, and grain with per-channel weights. It is applied on the GPU at display time — the photo stored and downloaded is the untouched original.
