### Flash (`flash`) Adds `flash` functionality with a fully custom pre-capture AE/AF/AWB trigger sequence for Android. 🎉 ```ts camera.current.takePhoto({ flash: 'on' // or 'auto' }) ``` ### Better photos (`qualityPrioritization`) We now also run the AE/AF/AWB precapture sequence on every photo (unless `qualityPrioritization` is `speed`), meaning photos are now less blurry, properly exposed, and properly white-balanced - so in short: **photo quality is now better!**. The fast path still exists when using `qualityPrioritization: speed`, as that will skip the precapture sequence and metering actions and just grab an Image from the Camera as quickly as possible. Additionally, `qualityPrioritization` now controls these options: - [COLOR_CORRECTION_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#COLOR_CORRECTION_MODE) - [EDGE_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#EDGE_MODE) - [COLOR_CORRECTION_ABERRATION_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#COLOR_CORRECTION_ABERRATION_MODE) - [HOT_PIXEL_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#HOT_PIXEL_MODE) - [DISTORTION_CORRECTION_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#DISTORTION_CORRECTION_MODE) - [NOISE_REDUCTION_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#NOISE_REDUCTION_MODE) - [SHADING_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#SHADING_MODE) - [TONEMAP_MODE](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#TONEMAP_MODE) ..by setting them to `_FAST` or `_HIGH_QUALITY`, which was previously left untouched. This now means: - `takePhoto({ qualityPrioritization: 'speed' })` got FASTER 🚀 - `takePhoto({ qualityPrioritization: 'quality' })` got BETTER QUALITY 📸 - `takePhoto({ qualityPrioritization: 'balanced' })` is left unchanged ✅
