What is the Huawei P20 Pro?
The Huawei P20 Pro is Huawei’s flagship smartphone. It runs on Android 8.1 Oreo and has a triple-camera system developed in tandem with Leica.
Labelled Leica Vario-Summilux-H1.6-2.4/27-80 ASPH, the triple camera combines a 1/2.78-inch 20Mp f/1.6 monochrome camera with a 1/1.73-inch 40Mp RGB (colour) f/1.8 wide-angle camera and a 1/4.4-inch 8Mp f/2.4 telephoto camera.
This makes 68Mp in total, but Huawei’s Light Fusion Technology combines the information from the three sensors so that by default images are output at 10Mp. This helps deliver better image quality as noise is reduced while dynamic range is extended.
If you prefer, images can be output at 40Mp but this sacrifices the ability to use the zoom function (see below for details) and it reverts to 10Mp when any of the subject shooting modes (Night, Portrait, Light Painting etc) are selected.
Using different focal length lenses equivalent to 27mm and 80mm enables the camera to zoom to 3x optically (80mm), but there’s also a digital zoom that enables up to 5x zoom (the equivalent of 135mm).
Artificial Intelligence (AI)
As in the Huawei Mate 10 Pro, the P20 Pro has artificial intelligence (AI) that helps the camera understand the subject and apply appropriate settings. The list of identifiable subjects includes cats, food, natural colours, close-up, night shots, text, greenery, portrait, dogs, fireworks, blue sky, flowers, stage, document, sunset, snow, waterfall and beaches.
When the camera detects one of these subjects in the standard Photo mode, it displays an icon on the screen. I found this worked well with the Mate 10 Pro. We are told that the P20 is even more sophisticated and able to identify a wider range of objects, such as different types of food for example, and apply different settings/processing accordingly. It managed to identify just about everything that I pointed it at.
The AI can also help with image composition and in some modes, the P20 Pro’s camera detects elements such as the horizon and suggests that you straighten the phone before taking the shot. It may also suggest framing a group shot a little wider to make the image look less cramped.
There’s also 4D predictive focus and AI to help the camera to track a moving subject such as a flower waving in a breeze .
In addition, the P20 Pro has a two-tone flash unit with a colour temp sensor built-in to look at the ambient light and adjust the flash to match.
Another reason for using more than one camera unit is to enable Aperture (also known as portrait or bokeh mode). When this is used the background can be blurred more than would normally be possible with a small sensor to replicate the appearance of images shot at a wide aperture with a camera with a large sensor.
In some modes, for example, Portrait mode, the P20 Pro automatically activates Aperture mode and there’s no need to select it.
Images shot in Aperture mode are tagged with an aperture icon and tapping it in review mode allows you to adjust the point of focus and the aperture. The widest aperture available is f/0.95, which gives very shallow depth of field (take a look at our sample images page for an example), while the narrowest is f/16 which renders much more of the image sharp.
Huawei claims that the stabilisation system in the P20 Pro, which is aided by AI, enables handheld exposures of up to 8 seconds to be made. I haven’t shot an exposure quite that long but I’ve taken several that are a few seconds long and the images are impressively sharp.
You can’t turn the stabilisation on or off in stills mode, it kicks in when it’s required or the shooting mode makes it necessary. It works in Night mode for example, and the camera composites several image files to make one sharp, correctly exposed shot. Traffic Trail mode (found within Light Painting mode), however, is a tripod-only mode as the stabilisation doesn’t help.
The stabilisation can also operate in video mode and it is very effective, making footage shot when you’re walking watchable. You can see a quick test of this feature in the video below.
The video below was shot at 2160×1080, the highest resolution available with stabilisation. It shows the impact of turning the stabilisation on when walking. The footage becomes much more watchable, but there’s a ripple or jello effect (rolling shutter) noticeable on the left of the frame.
Pro Mode and Raw File shooting
In addition to jpegs, it’s possible to shoot raw files with the P20 Pro. This option is located within the settings options of Pro shooting mode. If you switch away from Pro mode, the camera reverts to just shooting jpegs.
Pro mode gives you control over the metering mode, shutter speed, sensitivity (ISO), exposure compensation, focusing mode and white balance setting. While these are enticing for experienced photographers, you lose some of the magic of the P20 Pro. You can’t use the Aperture mode, for example, to blur backgrounds.
Once you’ve registered and signed into a Huawei Cloud gallery, up to around 100 tags can be applied automatically to your images. This effectively divides your images into album groups with headings such as ‘Highlights’, ‘People’, ‘Things’ and ‘Location’.
Surprisingly, given the P20’s ability to identify flowers and foliage, I found photographs of flowers in an album called ‘Landscapes’ under the ‘Things’ banner. I also take issue with its definition of ‘Sun in England’ which turned out to be a collection of shots I’d taken on a very wet day out with my dog.
Those images that the algorithm deems to be better will also be shown larger in the gallery view.
