Track your roll like a real film camera! Version 2.5 introduces an all-new continuous Film Frame Counter so you always know exactly which shot you’re on. Automatic Film Frame Counter: Keeps track of your roll from frame 0 to 36. Counting automatically wraps with each new roll, or extends linearly beyond 36 if you shoot longer rolls or bulk-loaded film. Smart Counter Sync: Manually editing a frame number resynchronizes the counter so your next shot seamlessly continues from frame + 1. Refined Photo Layout: ISO, aperture, and shutter speed are now clean and top-centered in the photo detail view, putting your technical exposure data right where you need it. Reliable EXIF & Frame Saving: Fixed an issue where black-and-white images dropped EXIF metadata. Your exposure settings and frame numbers are now preserved reliably across restarts and updates. Crafted to perfection to keep your analog workflow clean, accurate, and effortless. Happy shooting!
