The powerful camera of the Huawei P20 Pro offers you many possibilities that were previously only available with expensive cameras. This is the option to take photos in RAW format.

The RAW format corresponds to the uncompressed version of an image. In contrast, a JPEG is the compressed version of a photo. During the compression of photos, details are always lost, which can have a detrimental effect, especially in post-processing.

That's why there is the RAW format, where the photo stays exactly the same as it was taken by the camera. Therefore, the image size is many times larger than JPEGs. In the following we would like to show you how to activate the RAW mode in the camera app of the Huawei P20 Pro.

To do this, proceed as follows:

Take RAW photos with the Huawei P20 Pro

1. Open the camera app on the Huawei P20 Pro

2. Now switches to camera mode Pro

3. Now touch the gear icon in the top right corner of the live viewfinder 4. now activates the slider at "Raw Format" This will create RAW files in addition to the JPEG photo and save them to the internal memory.

You can now perfectly edit these photos to get the most out of your Huawei P20 Pro camera. Have fun with it!
