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.

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。
