I know, I know... 'film photography in 2024?' But hear me out. In the same way there's been a 'vinyl revival' with sales of vinyl recently outpacing CD sales for the first time in decades, there's also been a lesser known 'film revival'. Sales of film are steadily on the rise and Leica has even announced it's upping the production of its film cameras. Some say it's the 'look' that film gives you, or how enjoyable it is to shoot with something with all the mechanical craftsmanship of a vintage Cartier watch. For me, it's the way that film can keep you in the present moment while at the same time giving you something to look forward to in the future. Each time you release the shutter you're filling a Schrödinger's box of 36 surprises for your future self. There's something magical about the process of shooting on film that you simply don't get with digital. That said, when your photos come back looking like they've been shot on the vinyl b-side of Barry's Manilow's 'Could it be magic?', it can really make you rethink your decisions in life. (Plus, have you seen how much a roll of Portra 400 costs?) That's the situation that brought me to the App Store looking for a light meter app. Of course it had to be accurate, but I also wanted a UI that would get out of your way when shooting rather than a digital recreation of an antique light meter. Vintage tribute acts are fun, but they do get tedious when you're trying to complete a task. Nothing fit the bill. So I made one myself. Accurate, very. But also with a glanceable interface that gets out of your way while shooting and, more importantly, keeps you in the moment. It's unapologetic about its digital nature in the service of your next shot. The best of analog meets the best of digital. So, for all you film photographers out there, this is for you. I hope you enjoy it.

Achieving precision exposure for film photography with your phone involves using light metering apps and manual adjustments. Here's a general guide to help you: 1. **Light Metering Apps:** Download a light metering app on your smartphone. There are many available options, both free and paid, for both iOS and Android devices. Some popular ones include "Light Meter" for iOS and "Light Meter - Free" for Android. 2. **Calibrate the App:** Before using the app, calibrate it to ensure accurate readings. This typically involves adjusting settings such as ISO, shutter speed, and aperture to match your film camera settings. Refer to your camera's manual for these settings. 3. **Select the Film Speed (ISO):** Set the ISO value in the light metering app to match the ISO of the film you're using. This is crucial for accurate exposure calculations. 4. **Metering Mode:** Choose the appropriate metering mode in the app based on the lighting conditions and your desired exposure. Common metering modes include spot metering, center-weighted metering, and evaluative metering. 5. **Meter the Scene:** Point your phone's camera at the scene you want to photograph and use the light metering app to measure the light. Ensure that the app is reading the light falling on the subject, not the light source itself. 6. **Adjust Exposure Settings:** Based on the meter reading provided by the app, manually adjust the exposure settings on your film camera. This typically involves setting the appropriate combination of shutter speed and aperture to achieve the desired exposure. 7. **Take Test Shots:** After setting the exposure on your camera, take test shots to verify the exposure accuracy. Make adjustments as needed until you achieve the desired results. 8. **Bracketing:** Consider using exposure bracketing if you're unsure about the correct exposure. This involves taking multiple shots at different exposure settings to ensure that at least one captures the scene perfectly. 9. **Practice and Experiment:** Like any aspect of photography, achieving precision exposure with film takes practice and experimentation. Take the time to familiarize yourself with your camera's manual controls and how they affect exposure. Remember that film photography is a process of trial and error, and don't be discouraged if you don't get perfect results right away. With practice and experience, you'll become more adept at achieving precision exposure with your film camera and smartphone light metering app.
Congratulations on the launch! I'm curious, does the app offer any guidance or tips on achieving optimal exposure for different film types?
Wow congratulations ! Do not own an analog camera these days, but will keep this in mind. Congratulations on making an excellent product (4.8 stars w/ > 500 reviews on App store)
Okay, this looks good. I usually play with manual exposition (f, ISO, time) and with the iPhone, it is a bit tricky than with my camera. What is the main market you are targeting?
It's like a secret weapon for film photographers who love to capture life the analog way, but with a modern twist – totally worth the upvote! Quick question about usability for those who might be juggling an old-school camera in one hand and the app in the other, how intuitive is the interface? Can you get those precision readings without missing the moment you're trying to capture? It's all about finding that sweet spot between technology and practicality.
