As more brands are jumping on the dual camera wagon, they seem to be the next big thing for smartphone photography. But, are they better than single cameras in every aspect? We round up a list of advantages and disadvantages of having a dual camera aboard your smartphone.
First, it was HTC, then Huawei. Now, even Apple has equipped their latest model with dual cameras. This new type of smartphone camera has allowed manufacturers to improve the amount of features available on their devices and, at first sight, seem to be a welcome addition to their versatility; but there are some reasons that not all brands and manufacturers are thinking about switching to dual cameras just yet. Let’s gather some facts and information to understand why.
Advantages: better focus, more “tune-up” options
Thanks to the two cameras’ team work, the user can take pictures with a better focus for both center and background details, thanks to the cameras reliance on “binocular vision” or, if you prefer, the way our eyes work. Like the human eye does with the parallax effect, the dual camera system overlaps the image captured by both cameras to get the best results in terms of focus. The main camera usually focuses on the forefront while the second camera works on the background to add extra clarity and depth of field. Dual camera technology also allows for better refocus and extra tinkering after the picture is taken.
Disadvantages: higher energy consumption, lower resolution
However user-friendly dual cameras are, not everything about them is better than single cameras. They take a higher toll on the battery, not to mention the increased price tag of new phones sporting this type of camera, and also cannot compete with single cameras in terms of picture quality and resolution, as current dual cameras have an average 12MP and single smartphone cameras can go up to 20MP. In the end, the decision should be made taking into consideration what you look for in your camera and if it is worth the extra money you will spend.
