常见问题与知识点
什么是延时摄影拍摄间隔？
拍摄间隔是指两次快门之间的等待时间。对于植物延时摄影，间隔可以从几秒到几小时不等，取决于植物的生长速度。快速生长的蘑菇可能只需5分钟间隔，而多肉植物可能需要30分钟以上。
应该选择多少帧率？24、25还是30fps？
24fps是电影标准，画面更具"电影感"；25fps是PAL制式（欧洲/亚洲常用）；30fps是NTSC制式（北美常用），画面更流畅。对于社交媒体分享，30fps是最通用的选择。60fps会让画面异常顺滑但文件更大。
不同植物的推荐拍摄间隔是多少？
快速生长类（蘑菇、竹笋）：2-5分钟；中等速度（豆芽、牵牛花）：5-15分钟；慢速生长（多肉、仙人掌）：30-60分钟；花朵绽放：3-10分钟。使用本工具的预设场景可快速获得推荐值。
拍摄时如何保证相机续航？
长时间延时摄影建议使用外接电源（USB供电或假电池）。如果只能使用电池，请根据拍摄间隔估算总拍摄次数，确保电池能支持。大多数相机单块电池可拍摄300-800张，间隔越短耗电越快。
需要多大的存储卡？
使用本工具的存储预估功能。一般来说：7天中等间隔拍摄约产生700-1500张照片。JPEG格式约需8-16GB，RAW格式约需25-50GB。建议携带备用存储卡，并定期检查存储空间。
延时摄影需要恒定光照吗？
是的，光线变化是延时摄影最大的挑战。建议使用全光谱植物生长灯提供24小时恒定光源，避免日光变化导致画面闪烁（flicker）。如果使用自然光，确保每天同一时段的光线条件相似，并在后期使用去闪烁软件处理。
拍摄间隔太短有什么问题？
间隔过短（<3秒）可能导致相机缓冲区溢出、存储写入跟不上，或快门寿命过度消耗。另外过短的间隔在后期观看时可能无法察觉植物变化。建议对于大多数植物，间隔不低于10秒，除非拍摄极快速生长的物种。
如何确保拍摄稳定性？
三脚架是必须的。确保相机完全固定，避免任何移动。关闭镜头防抖功能（使用三脚架时防抖反而会引入模糊）。使用快门线或内置间隔计，避免手动触发造成的抖动。在拍摄区域贴标记以便意外移动后复位。

专业提示：如何获得丝滑的植物延时视频
使用全手动模式（M档）：固定光圈、快门、ISO和白平衡，避免自动曝光导致的闪烁。 拍摄RAW格式以便后期调整白平衡和曝光。 视频帧率选择30fps对于大多数平台（YouTube、Instagram、TikTok）都是最佳选择。 最终视频时长建议15-45秒——这是社交媒体上表现最好的长度。
