How the app handles this stock
- Box speed: ISO 640. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: No reciprocity correction needed; metered time is the shot time.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. B&W negative decay rates are baked in.
