Image quality is not just about megapixels. Here are 7 useful facts that help define image quality.
When it comes to image quality, there is a big misconception that if you want better quality, you need more megapixels. Unfortunately (or fortunately, depending on how you look at it) it isn’t that straightforward.
Over the years camera manufacturers have dedicated much of their efforts to improve the number of megapixels in their latest models. At the start of the century, both Nikon and Canon were producing DSLRs with just 3MP — a far cry from the 100MP cameras we see today. This drive has led many to believe that megapixels are all that matters when it comes to image quality, but to better understand image quality, considering the number of megapixels alone isn’t enough. You also need to look at the size and type of image sensor, understand how images are formed, how light is focused onto the sensor, the impact of lens choice and quality, and consider the pixel size to get the full picture.
