Android camera callbacks refer to the data obtained by setting a previewing callback for the Camera instance. For example, set `camera. setPreviewCall back (newCamer. PreviewCall back () { @Override publicvoidonPreviewframe(Byte[] data, Camera camera) {...}})` The `data` in is the raw data of the callbacks. These raw data could not be directly saved as images. They needed to be converted into commonly used image code data. By default, most of the data supported by the camera is in the NRV21 format. You can use `YuvImage` to process the data that is in YMV code, such as `YuvImage image = new YuvImage(data, ImageForm.NRV21, width, height, zero);`, and then compress it into Jpeg-format with `ByteArrayOutpuStream`. After that, you can convert it into new data for various operations, such as saving it as an image, converting it into a Bitmap, and so on.
In addition, Android provides two kinds of camera callbacks: Camera. picturecallback and Camera. previewcallback. The interface 'PictureCallback' is used to process the data of the captured photos, and the interface 'PreviewCallback' is used to process the data of the previews. When you use the camera callbacks to process data, you need to create and implement the corresponding methods in the code. For example, you need to create an implementation class object of 'Camera. Picture callback', and implement the' onPicture Taken ()'method in the implementation class to process the photo data after shooting.
At the same time, before you start to use the camera function, you need to add the corresponding permission and feature declaration in the `AndroidManifest.xml` file, such as `

In portrait photography, different focal lengths had their own characteristics and uses. It was difficult to determine which lens was used the most. However, the following shots were more commonly used in portrait photography: - ** 35mm and 50mm lenses **: These two focal lengths are more commonly used for home or novice portraits. The 35mm lens was an environmental portrait lens that was between wide-angle and 50mm standard focal length. It could accommodate people and the surrounding environment well in the picture. It could be used to take full-body photos, suitable for expressing the surrounding environment of the subject, shooting a sense of story, and also convenient for communication with the subject. It was suitable for shooting children or cultural photography scenes. The 50mmF1.8 lens was a relatively cheap large-aperture focal point, which was easy to produce the effect of blurring the background. It was suitable for beginners to practice composition, and it could shoot half-body and full-body portraits. - ** 85mm and 135mm lenses **: These two focal lengths are usually regarded as professional portrait lenses. The angle of view of the 85mm lens was 28 degrees, and the background blurring effect was good. It could simplify the background and highlight the character. The distance from the full-body shot to the close-up was about 1.5 meters to 5 meters. The image quality was good, suitable for shooting half-length portraits or close-ups. It could get a cream-like out-of-focus effect. The 135mm lens was a close-up shot of a portrait, which could bring a stronger sense of compression and better blurring effects. It could separate the character from the background very well. - **70 - 200mm lens **: This focal length lens is used more for the convenience of composition. It can zoom in on people and objects in the distance without moving your feet, strongly compressing the space, making the picture concise and full. It can blur the background and background to highlight the main body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
