常见问题
定影是怎么出片的？
只有一个拍摄模式。按下快门，定影拿到原始数据，再由自己的显影引擎冲洗成照片，不用 iPhone 自带的成片风格。在支持 ProRAW 的 Pro 机型上，自动曝光用苹果的 ProRAW 底片；手动曝光（快门或 ISO 任一手动），以及没有 ProRAW 的机型，会连拍一组 RAW、对齐后合成一张更干净的底片。28 / 35 / 50mm 用多帧超分辨率，只合成传感器真实拍到的细节，不靠 AI 生成。
按下快门后要等吗？能接着拍吗？
合成和显影在后台进行，可以接着拍下一张。左下角小图上有一个小点时，表示这张还在处理，处理完会自动存进相册。处理中切到别的 app 没关系，回来会接着处理。处理完之前尽量不要从后台把 app 划掉：已经合成好的会在下次打开时补存，刚按下快门、还在合成的那一张可能会丢。
存什么格式？怎么留 RAW 底片？
默认存 HEIF。打开 RAW 按钮后，会同时存一张 DNG 底片，可以在任何支持 DNG 的软件里后期。
彩色和黑白有什么区别？
黑白和彩色用同一套曝光和影调，黑白再稍微加一点反差。黑白可以选滤镜（无、黄、红、绿），默认是黄，效果类似黑白胶片前面加的滤色镜。
为什么没有光圈调节？
iPhone 的镜头光圈是固定的。
在哪里看拍好的照片？
点左下角的小图可以看刚拍的那一张，能放大、分享；点"在相册中打开"去系统"照片" app 看全部。定影不在 app 里另做相册。
哪些 iPhone 能用？
需要 iOS 18 或更新。支持 iPhone 12 Pro 及之后的所有 Pro 机型，以及 iPhone 16 及之后的机型（包括 iPhone 16e、iPhone Air）。iPhone 14、15 标准款可能只能部分使用。更早的非 Pro 机型、iPhone 11 Pro 和 iPhone SE 拿不到定影需要的原始数据，打开后会提示无法出片。
Stille 会收集我的数据吗？
不会。Stille 不联网，详见隐私政策。

FAQ
How does Stille make a photo?
There is one shooting mode. When you press the shutter, Stille takes the raw sensor data and develops it with its own engine instead of the iPhone's built-in look. On Pro models with ProRAW, auto exposure uses Apple's ProRAW negative. With manual exposure (shutter speed or ISO set by hand), and on iPhones without ProRAW, Stille captures a burst of RAW frames, aligns them and merges them into a cleaner negative. At 28 / 35 / 50 mm it uses multi-frame super-resolution, built only from detail the sensor actually recorded, with no AI generation.
Do I have to wait after pressing the shutter? Can I keep shooting?
Merging and developing run in the background, so you can keep shooting. A small dot on the thumbnail at the bottom left means that photo is still being processed; it is saved to your library automatically when done. Switching to another app is fine; processing resumes when you come back. Try not to force-quit the app before processing finishes: a photo that has already been merged is finished the next time you open the app, but one that is still being merged right after the shutter may be lost.
What format does Stille save? How do I keep the RAW negative?
HEIF by default. Turn on the RAW button to also save a DNG negative, which opens in any software that supports DNG.
What's the difference between Color and Black & White?
Both looks share the same exposure and tone curve; Black & White adds a little more contrast. It lets you pick a filter (none, yellow, red or green); yellow is the default, like the color filters used with black-and-white film.
Why is there no aperture control?
iPhone lenses have a fixed aperture.
Where do I see my photos?
Tap the thumbnail at the bottom left to view your latest photo (zoom and share), then tap "Open in Photos" to see the rest in the Photos app. Stille doesn't keep a separate gallery.
Which iPhones are supported?
iOS 18 or later. Works on iPhone 12 Pro and all later Pro models, and on iPhone 16 and later (including iPhone 16e and iPhone Air). iPhone 14 and 15 (non-Pro) may have limited support. Earlier non-Pro models, iPhone 11 Pro and iPhone SE can't provide the raw data Stille needs, and the app tells you so when you open it.
Does Stille collect my data?
No. Stille has no network access. See the Privacy Policy.
