Frequently Asked Questions
Where does the development data come from?
The data is sourced from publicly available film development charts, cleaned and verified for accuracy.
Is my data backed up to the cloud?
No. All data is stored locally on your device. You can export or import a local backup JSON from About → Data & Backup using the system Share Sheet or Files. Deleting the app without a backup will remove your favorites, session logs, and other local data. We recommend exporting a backup of important records.
The timer notification didn't sound. What should I do?
Please make sure notifications are enabled for DevGlass in Settings → Notifications. Also check that your device is not in Silent Mode, and review in-app sound / haptic preferences. System sounds may be muted when the device is in Silent Mode.
How does temperature compensation work?
DevGlass uses a standard time–temperature relationship: compensated time = base time × 2^((base temp − actual temp) / 10). This provides a reliable estimate for most B&W films and developers.
What are post-development ratings?
After a session, you can optionally rate density (e.g. thin / normal / thick), ideally after drying or scanning. Ratings are optional, stored only on device, and help suggest a personal starting time. They do not change the chart's standard times.
Why do some Jobo tanks show two volumes?
Inversion and rotary processing use different solution volumes. Dilution presets list them separately so you can mix for the method you use.
Can I suggest a feature or report a bug?
Absolutely. Please email us at argentglasslab@gmail.com. We appreciate your feedback.

常见问题
显影数据来源是什么？
数据来源于公开的胶片显影数据表，经过清洗和验证以确保准确性。
我的数据会备份到云端吗？
不会。所有数据仅存储在您的本地设备上。您可在「关于 → 数据与备份」中通过系统分享面板或文件选择器导出 / 导入本地 JSON 备份。若未备份即删除应用，收藏、冲洗日志及其他本地数据将被移除。建议对重要记录另行导出备份。
计时器通知没有响，怎么办？
请确认在「设置 → 通知」中已为 DevGlass 开启通知权限，同时检查设备是否处于静音模式，并查看应用内的声音 / 触感偏好。设备处于静音模式时，系统提示音可能无声。
温度补偿是如何计算的？
DevGlass 使用业界常用的时间–温度关系：补偿时间 = 基准时间 × 2^((基准温度 − 实际温度) / 10)。该关系适用于大多数黑白胶卷和显影液。
冲后评价是什么？
冲洗结束后，您可选择评价密度（如偏薄 / 正常 / 偏厚），建议在晾干或扫描后再评。评价为可选，仅保存在本机，用于给出个人起始时间建议，不会修改图表中的标准时间。
为什么有的 Jobo 罐会显示两个容量？
倒转冲洗与旋转冲洗所需药量不同。配液预设已分列，便于按您实际使用的方式配制。
我可以提出功能建议或报告问题吗？
当然可以。请发送邮件至 argentglasslab@gmail.com，我们非常感谢您的反馈。
系统要求
iOS 17.0 或更高版本。兼容 iPhone 和 iPad。
