Lightme vs FilmMeter

Lightme - Lightmeter is a clean, simple to use yet very powerful lightmeter. It is optimised for an easy one-handed use, both for left-handed and right-handed users, with the main controls within your thumb's reach, without the fatiguing juggling of your precious smartphone. A core distinguishing feature of Lightme - Lightmeter is that - differently from most of the other apps - it can show multiple combinations of valid settings for aperture and shutterspeed at the same time by working like a - stretched out - old needle and wheel lightmeter. This allows the user to quickly pick the desired settings without having to scroll on a tiny wheel picker. The app is designed to be welcoming to people who are just starting out, with a simple one-button use. But it offers many useful and advanced features for the more experienced shooters/users: Continuous metering (by pressing and holding or double tapping the measure button) Spot metering with a variable zoom (for more precision) which also supports average metering, and a very intuitive implementation of the zone system Automatic reciprocity failure compensation (for 25+ films, if you see exposure times in red, they are being compensated) A dedicated pinhole mode with precise exposure times for user defined apertures (multiple apertures at a time), with the possibility of setting a timer (through a shortcut) Incident light metering with calibration when using the front facing camera And more ... It also includes some other features that are enjoyable by any kind of user: Black and white preview The ability to use any of the cameras on your smartphone (swipe left/right on the preview) Multiple presets for your different camera/film/lens setups Framelines for previewing your shot, before setting up your tripod etc. A searchable list of useful tips to make better use of the application's potential A searchable list of more than 70 films to choose from with the possibility of selecting a few favourites Dark mode support and a useful level of customisation You can find even more info in the tips inside the app or you can have a look at full user manual by tapping on manual (in the settings) The app is free in all its many functionalities, but it offers In-App-Purchases in order to support the project. The only minor perk you can enable only via certain IAPs is the replacement of the Ad button with a label containing the name of your current preset, check under settings -> coffee for more info. Don't panic though, even if there's an Ad button it doesn't mean I'm going to show you ads. In fact unless you decide to tap on that button I'm never going to show you any. But if you have a few minutes to spare, watching a few of them sure helps keeping this project alive :) Try it, and, if you like it, share it with your friends and consider writing a (mini) review ;) Have a nice day, and good light!

FilmMeter turns your iPhone into a professional light meter for film cameras. Real-time metering, LiDAR ranging, reciprocity calculation, and exposure logging — one app covers your entire shooting workflow from loading film to the final frame. Metering Measure exposure in real-time using your iPhone camera. Spot metering reads any point precisely, while average metering balances the whole scene. Full control over aperture, shutter speed, and ISO. iPhone 16 users can meter and adjust EV directly with the Camera Control button. Ranging & Depth of Field Get accurate focus distance with LiDAR-enabled devices. The depth of field scale shows your sharp range and hyperfocal distance, supporting 35mm (full frame) and medium format calculations. Camera Management Create profiles for your cameras and lenses. Set focal length and aperture range for each lens, then link a camera when loading film — aperture selection is automatically constrained to your lens's actual range. Manage your digital film bag the way you manage your real gear. Film Roll Management Create a roll, select your film stock, start shooting. Push/pull processing support lets you set development stops and automatically converts to effective ISO. Each metering links to your current roll automatically. The frame counter tracks remaining shots. Mark rolls as in progress, finished, or developed. ND Filters Built-in support for ND2 through ND10000. Select a filter and exposure is compensated automatically — no manual stop conversion needed. Pair with the long exposure timer to master daytime slow shutter work. Reciprocity Compensation Film loses sensitivity during long exposures. FilmMeter includes reciprocity data for popular film stocks and calculates the corrected shutter time automatically. Long Exposure Timer Long-press the metering button to start a countdown. The timer integrates with Dynamic Island — visible even when locked. Get notified when your exposure completes. No more counting seconds for star trails or light painting. Smart Exposure Suggestions Built-in scene recognition analyzes your frame. In tricky lighting like snow, backlight, or night scenes, it tells you "add one stop" instead of leaving you to figure it out. Exposure Log Every metering saves full parameters and location. Export to CSV. Review your decisions, build your film notes.
