Edit your logged shots Recorded something wrong? Swipe left on any shot and tap Edit to fix the exposure, gear, filters, flash, zone, date, location, and notes. The shot stays on the same roll and derived values recalculate automatically. Get every frame off your roll Rolls now let you log a few extra frames past the declared count, just like real film that often gives you 37-40 on a 36 roll. You'll see a gentle "roll finished" hint instead of being blocked. More reliable sun alerts Sunrise, sunset, and golden/blue hour alerts now reschedule when you reopen the app, and no longer clear themselves when your location is briefly unavailable. Plus small fixes and polish. Thanks for shooting with F8t!
