Intelligent Profile Linking auto-shift warnings
Auto-warn when changing film, gear, or filter would shift exposure beyond comfort.
Where to find it
Implicit in profile film filter switching across the UI
Summary
Linkage between the gear/film/filter selections so changing one surfaces a warning if the change would silently shift exposure (e.g. swapping in a stock with different reciprocity, mounting an ND filter). Reciprocity link is shipping; latitude shift warnings are still partial.
How it works
What is shipping today
When you change the loaded film stock, the meter immediately re-applies the new stock's reciprocity exponent so long exposures get the right correction without you having to remember. Same for the box-speed ISO pin: switching stocks updates the ISO wheel automatically.
Current limitations
Latitude shifts are not warned. If you switch from a wide-latitude negative stock to slide film mid-roll, the Development Advisor will use the new film's latitude on next reading, but no chip surfaces calling the change to your attention. Similarly, changing filters between exposures does not warn even though the filter factor is applied.
What's planned
Surface a passive chip on stock change when the new stock's latitude differs by more than a stop from the previous one, or when the new stock has reciprocity behaviour that materially changes long-exposure timing for the current EV reading. Same for filter changes that would push the meter past the camera's shutter range.
