You do so with `ImageCapture.Builder` methods.\n| **Note:** For a general overview of how to capture images with CameraX see the [Image capture guide](/media/camera/camerax/take-photo).\n\nSet capture mode\n----------------\n\nUse [`ImageCapture.Builder.setCaptureMode()`](/reference/androidx/camera/core/ImageCapture.Builder#setCaptureMode(int)) to configure the capture mode\nwhen taking a photo:\n\n- [`CAPTURE_MODE_MINIMIZE_LATENCY`](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_MINIMIZE_LATENCY()): optimize image capture for latency.\n- [`CAPTURE_MODE_MAXIMIZE_QUALITY`](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_MAXIMIZE_QUALITY()): optimize image capture for image quality.\n\nThe capture mode defaults to [`CAPTURE_MODE_MINIMIZE_LATENCY`](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_MINIMIZE_LATENCY()). For more\ninformation, see the [`setCaptureMode()`](/reference/androidx/camera/core/ImageCapture.Builder#setCaptureMode(int)) reference documentation.\n| **Note:** There is also an experimental [Zero-Shutter Lag mode](/media/camera/camerax/zsl) available through [`CAPTURE_MODE_ZERO_SHOT_LAG`](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_ZERO_SHUTTER_LAG()).\n\nSet flash mode\n--------------\n\nThe default flash mode is [`FLASH_MODE_OFF`](/reference/androidx/camera/core/ImageCapture#FLASH_MODE_OFF()). To set the flash mode, use\n[`ImageCapture.Builder.setFlashMode()`](/reference/androidx/camera/core/ImageCapture.Builder#setFlashMode(int)):\n\n- [`FLASH_MODE_ON`](/reference/androidx/camera/core/ImageCapture#FLASH_MODE_ON()): Flash is always on.\n- [`FLASH_MODE_AUTO`](/reference/androidx/camera/core/ImageCapture#FLASH_MODE_AUTO()): Flash is automatically on for low-light shots.\n\nFile types\n----------\n\nThis workflow demonstrated in this document fully supports the [`JPEG`](/reference/android/graphics/ImageFormat#JPEG)\nformat. For sample code that shows how to convert a [`Media.Image`](/reference/android/media/Image) object\nfrom `YUV_420_888` format to an RGB [`Bitmap`](/reference/android/graphics/Bitmap) object, see\n[`YuvToRgbConverter.kt`](https://github.com/android/camera-samples/blob/3730442b49189f76a1083a98f3acf3f5f09222a3/CameraUtils/lib/src/main/java/com/example/android/camera/utils/YuvToRgbConverter.kt)."]]
