## What is Film Light?

Film Light，做你口袋里的专业数字测光表！适用于胶片摄影、影视灯光。

基于场景参考(Scene-Referred)的专业摄影测光表 APP。基于 Apple Log 色彩管线，高效测光，精准预览。独创的拟物风拨盘测光 UI，可快速进行光圈优先，快门优先以及手动曝光预览模式切换。内置经典胶片模拟LUT，亦可自定义导入 .cube 文件。支持近 1 度精准点测、智能矩阵测光。便捷的曝光补偿、ND 滤镜计算。

独创的测距功能，依靠LiDAR硬件，实时计算并预览你的景深范围。具备深度俯视图、深度伪色功能。估焦相机再也不用靠猜了！

不止是测光表，更是你的摄影日志。内置相册功能，支持项目与胶卷管理；相册可查看 EV 点表、随时切换 LUT 预览，让每一次曝光决策都留有记录。

机型要求：
iPhone 15 Pro 及后续支持 Apple Log 的机型可获得完整体验。在不支持 Apple Log 的机型上，Film Light 将以 HLG 模式运行；由于该模式下的画面经过局部影调映射（LTM），任意移动取样点后的读数无法保证准确，因此自定义 EV 点表结果并不准确。
测距功能需要使用搭载 LiDAR 硬件的 iPhone，需要 iPhone 12 Pro/Pro Max 以上的 Pro/Pro Max机型。

## Key features

- Scene-referred professional metering
- Precise preview with Apple Log
- Analog-style dial UI for exposure modes
- Built-in and custom LUT support
- Accurate spot and matrix metering
- Exposure compensation and ND filter calculation
- LiDAR-based distance and depth of field preview

## Frequently asked questions about Film Light

### What is Film Light?

Film Light is a professional digital light meter app designed for film photography and videography. It offers advanced metering capabilities, scene-referred previews, and a unique LiDAR-based depth of field preview.

### What devices does Film Light support?

Film Light is available on iPhone. For the full experience with Apple Log, iPhone 15 Pro and later models are recommended. The LiDAR distance function requires iPhone 12 Pro/Pro Max or later models with LiDAR hardware.

### How does the LiDAR distance function work in Film Light?

The LiDAR function in Film Light uses your iPhone's hardware to measure distances in real-time, allowing for accurate depth of field previews. This helps estimate focus ranges, especially for rangefinder cameras.

### Can I use Film Light on older iPhones?

On models that do not support Apple Log, Film Light operates in HLG mode. However, due to local tone mapping (LTM) in HLG mode, readings from arbitrary sampling points may not be accurate, and custom EV point table results might be imprecise.

### Does Film Light have ads?

No, Film Light does not contain advertisements. It is a paid application.

### What is the price of Film Light?

Film Light is available for a one-time purchase of $1.99.
