Are you a meticulous film photographer that prefers to record settings/locations for the film photos that you take? Are you looking for a simple and easy to use app for tracking and logging that information? Are you tired of the buggy, crash-prone, or convoluted photo logging apps currently available? I happen to be all of those things. Which is why I developed MetaLog. MetaLog is a simple yet powerful data logging utility for photographers who want to quickly record photo metadata for photo cataloging or EXIF tagging during post-processing. In addition to keeping track of the settings for each photo, MetaLog can also act as an equipment inventory for your gear. Feature Highlights: • See all of your added film rolls at a glance, including the number of frames added to each roll, as well as load/unload dates to show which rolls are still in use. • Quickly log settings for each photo including date, lens, aperture, shutter speed, exposure compensation, as well as location coordinates, accessories, and notes about the shot. • Intelligent pre-fill and filtering for dates, locations, and equipment, making adding new frames a snap. • Easily manage multiple rolls loaded into multiple cameras simultaneously. • Pinpoint photo locations with a simple and familiar pinch-and-zoom map interface. • Export all logged data as convenient CSV files. • Gear pages can record camera and lens models as well as serial numbers, allowing for a complete gear inventory that's handy for tracking and insurance.
