TimerGlass - Support / 技术支持

Q: How do I calculate corrected exposure time?

A: Select your film stock, set the metered exposure time, optionally add filters and bellows compensation, and the corrected time is displayed automatically.

Q: My film is not in the list. What should I do?

A: Go to Settings > Custom Films to add your own film with a custom reciprocity correction factor (P value) or lookup table. If you know the P value from the film's data sheet, enter it there.

Q: How accurate is the calculation?

A: TimerGlass uses official manufacturer data where available, with log-log interpolation for lookup table films. Results may vary slightly from other apps due to different interpolation methods. For practical purposes, the difference is negligible.

Q: Does the app work offline?

A: Yes. TimerGlass works entirely offline with no internet connection required.

Q: How do I change the language?

A: Go to Settings > Language. You can choose from English, Simplified Chinese, Traditional Chinese, Japanese, German, or French. You can also follow your system language setting.

Q: How does the timer work with the shutter?

A: Tapping "Set Timer" loads the exposure but does not start counting. Switch to the Timer tab and tap the large start button at the moment you open the shutter, so the countdown matches your actual exposure. Stopping requires a one-second hold to prevent accidental taps.

Q: Why did I get a notification after the timer finished?

A: If you are away from your phone when a long exposure ends, TimerGlass sends a completion alert plus follow-up reminders so you don’t forget to close the shutter. They are cancelled automatically once you return to the app.

Q: My filter is not in the list. What should I do?

A: In the filter picker, scroll to the "Custom" section and add your own filter with its measured light loss in stops (useful for variable NDs or old filters that differ from their marked values).

Q: How do I share an exposure?

A: Tap the small share icon next to a result (calculator, pinhole tool, or history detail). You’ll see a preview of a vintage-style card that you can share or save to Photos.

问：如何计算修正曝光时间？

答：选择胶片，设定测光时间，按需添加滤镜和皮腔补偿，修正后的曝光时间会自动显示。

问：我的胶片不在列表里怎么办？

答：进入设置 > 自定义胶片，可以添加自己的胶片并设定修正系数（P 值）或查找表。如果你知道胶片数据表上的 P 值，直接输入即可。

问：计算精度如何？

答：TimerGlass 尽可能使用厂商官方数据，对查找表胶片采用对数插值。与其他 app 可能会有微小差异，这是由不同的插值方法造成的，实际使用中差异可以忽略。

问：需要联网吗？

答：不需要。TimerGlass 完全离线运行，无需任何网络连接。

问：如何切换语言？

答：进入设置 > 语言，可选择英文、简体中文、繁体中文、日文、德文或法文，也可以跟随系统语言设置。

问：计时器怎么和快门配合？

答：点「启动计时器」只是装填曝光参数，不会开始倒计时。切到计时器页后，在打开快门的同一瞬间按下大的开始按钮，让倒计时和实际曝光对齐。停止需要长按一秒，防止误触毁掉长曝光。

问：计时结束后为什么还会收到提醒？

答：长曝光结束时如果你不在手机旁，TimerGlass 会发送完成提醒和后续追加提醒，避免忘记关快门。回到 app 后剩余提醒会自动取消。

问：我的滤镜不在列表里怎么办？

答：在滤镜选择页底部的「自定义」分区，可以按实测档数添加自己的滤镜（适合可变 ND 或与标称值有出入的老滤镜）。

问：如何分享曝光参数？

答：点结果旁的小分享图标（计算器、针孔工具、历史详情都有），会先看到复古风卡片的预览，可以分享或存入相册。
