Huawei P20 Pro is the first smartphone to feature triple-rear camera setup. The first and the main camera is a 40-megapixel f/1.8 RGB sensor which is 1/1.7 inch in size. This is one of the biggest image sensors in a smartphone as of now, with a pixel size of up to 2 micron.
The second camera on the Huawei P20 Pro has a 20MP f/1.6 Monochrome sensor which works with the first camera to capture more details and texture in a photo. Both these cameras also work together to product bokeh effect when used in portrait mode.
The third camera features an 8MP f/2.4 image sensor which allows 3X optical zoom and 5x hybrid zoom. This 8-megapixel sensor also has OIS (Optical Image Stabilization) which can be used at up to 5x hybrid zoom. While the first two 40-megapixel and 20-megapixel camera sensors feature AIS (Artificial Intelligence Stabilization). Huawei claims that these two cameras on the P20 Pro work really well with AIS, that the OIS was not a necessity.
How Three Cameras on Huawei P20 Pro Work Together?
So basically, the 40-megapixel RGB sensor captures the colors and the details in the scene. The 20-megapixel monochrome sensor captures the texture and more details, and it also senses the depth in a scene to give bokeh effect.
And finally, the third 8-megapixel sensor is used to optically zoom up to 3x and help in 5x hybrid zoom. The third camera also ensures that the video is stable by using the OIS.
I would also like to highlight some more attractive features in Huawei P20 Pro such as Super Slow Motion video 960fps @ 720p and 240fps @ 1080p. You would also be able to click a 5-second long exposure photo handheld, you do not need a tripod for that.
