Phones with multiple cameras are the new norm. There’s hardly a phone launched that sports a single camera.
What started out as an endeavour to deliver bokeh or depth to images on dual camera phones — where the background is blurred but the face in focus — is now evolving into triple cameras.
The third camera setup that’s starting to appear on every smartphone is normally being used to enhance a phone’s zooming capabilities or capture more details in a single frame.
Another use of the triple camera setup is giving smartphones greater capacity to zoom in. Last year, Huawei started the trend with the Huawei P20 Pro that had 3x zoom.
This doesn’t only mean enhancing a camera’s digital zoom — which only blurs the image as you get closer. It can also enhance a camera’s optical zoom to avoid loss in detail. Putting in a monochrome sensor makes cameras more sensitive to light. They are better to detect contrast and differentiate between different gradients of light and dark. This also means that the edges of objects in images will be clearer.
A monochrome sensor also delivers better image stability. Most smartphones today come with image stabilisation software, but it can only do so much.
The more lenses you have, the more pixels are being captured. This doesn’t necessarily mean that the photo quality will be better but it does mean that the photo will be larger allowing you to crop without hassle.
