Lightme - Logbook is a clean and powerful tool to record and keep track of your rolls, shots, developments, and all the gear that revolves around shooting film — from 35mm to medium and large format. The idea behind it is simple: logging a shot should take seconds, not steal time from actually shooting. Lightme pairs a beautiful, immediate interface with enough depth and flexibility to fit any workflow, whether you shoot a couple of rolls a year or fill several large format holders in an afternoon. LOGGING, EFFORTLESSLY • Log a shot in seconds: aperture, shutter speed, focal length, filters, bellows correction, measured EV, notes and more • Log straight from your wrist with the companion Apple Watch app, with Siri and Shortcuts, or from the home screen and lock screen widgets • Together with the Lightme Lightmeter app, your meter readings can prefill a new shot automatically • Every shot can carry a location and address, a preview photo, and later its final scan, plus a star rating ROLLS, SHEETS AND DEVELOPMENTS • Track rolls from loading to unloading, with film stocks from a growing database and a processing pipeline: waiting for development, off to the lab, back from the lab, to be scanned, scanned • Keep detailed development notes — developer, dilution, time, temperature, agitation — for rolls and single sheets alike, including push/pull (N+ / N-) development • Add post-development notes and a photo of the final result to rolls, sheets and individual shots YOUR GEAR, ORGANIZED • Cameras and lenses with nicknames, formats (including custom formats you define), pinhole and bellows flags, custom shutter speeds and selectable shutter step sizes • Roll film backs and lens filters with their exposure compensation • Film holders and backs can be marked as compatible with specific cameras, and everything is searchable from a single bar LARGE FORMAT, COVERED • Keep track of your film holders with three states — unloaded, loaded and exposed — always knowing which film is inside each one • Group holders together and follow every sheet from exposure through development INSIGHTS FROM YOUR DATA • Build and save custom queries, filtering by date (fixed or rolling windows), camera, lens, film stock, format, ISO, aperture, shutter speed, focal length and notes • Visualize results with histograms — by camera, lens, film stock, shutter speed, aperture, focal length, ISO, format, rating or hour of the day — alongside aggregate stats like mean aperture and average exposure • Save the queries you use most and re-run them anytime YOUR DATA, YOURS • Everything syncs privately through iCloud across your iPhone and iPad • Export any selection of data as CSV or JSON, or as a beautifully formatted PDF with customizable columns and a contact-sheet mode, bundled with your images in a single ZIP • Batch-write shooting metadata (EXIF) onto your scans — for a whole roll at once, or by matching files from the Files app • Viewing and exporting your data is free, forever; adding and editing is unlocked with a one-time purchase or a subscription AND MORE • Full-text search, favourites and an archive to keep things tidy • Available in English, Italian, Spanish, Japanese and Simplified Chinese • A roadmap of what's coming next lives right in the app — new very cool features are on the way :) If you have any suggestion or issue, write me at lightme.apps@gmail.com Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Dehancer Color Test is based on the color perception study by co-founders of Dehancer Pavel Kosenko, Nailya Safarova & Denis Svinarchuk, experts in Image Processing. This experimental tool helps you determine how many colours you perceive under different colour target display conditions. The test results include two values: 1. The number of colors you can perceive It is an index of color perception involving short-term memory. In simpler terms, it represents the ability of aesthetic perception under momentary examination. The result depends on the visual experience and your demand for colour nuance. You can take this test regularly to improve your perceptual vision. 2. The current effectiveness of your perception relative to your theoretical potential With some reservations, the potential represents the limit of your physiological ability, as measured at the level of the sensory visual system. Sensory vision is also trainable, but to a lesser extent. Perception depends on lighting conditions, physical and emotional state, and effort. Also, the results may vary over time and as your visual experience improves. The testing method is part of a live experiment, so we admit measurement inaccuracies. The statistics we collect do not contain personal data and are stored in anonymized form. This app is not intended for medical diagnosis. Any result is normal and reflects your personal demand for nuanced color perception. Dehancer’s mission is to preserve the aesthetic heritage by means of digital tools for color correction and lifelike emulation of analog processes and effects.
