Comprehensive Digital Photography Insights: Megapixel Woes & Truths
Dear photographers. Here’s a story about photography entitled “The Megapixel Race”. This is a very important information to know and it might even surprise you when you know the real deal. Read along and you will find out what it is!
One of the features in digital cameras is the total pixel it can process when taking a photo. A pixel is defined as a single unit of data which has information such as colour, brightness, and darkness of a picture. Pictures converted into digital form consist of many pixels, same concept as how matter consists of many molecules and atoms. It is these pixels which form the digital photo.
Here is another topic but related to the initial idea. Our eyes are limited to a specific resolution of 0.35mm at 1 metre distance. This tells us that that our eyes, assuming that it has perfect 20/20 vision, can differentiate two objects that are a minimum of 0.35mm apart, with the objects being 1 metre away from our eyes. This is one of the reason why the camera companies started the megapixel race in digital cameras.
One megapixel has one million pixels. For example if a camera has one megapixel, it has the capability of generating one million pixels resolution photo, with 1024 pixel for the width and 768 pixels for the height (Multiply 1024 with 768 and you will get approximately 1 million )
The race started approximately 8 years ago when digital cameras were first released. One of the easiest ways to increase the ”quality” of the photos is to increase the number of megapixels a camera can generate. Why?
Because if you were to view a 1 megapixel photo and a 4 megapixel photo of the same size, the latter will have a much smaller pixel size compare to the former because more pixels are forced into the photo for the same size (Does this make sense? ).
Therefore the picture will “appear” to be clearer because our eyes are not able to resolve as the pixels are getting smaller and smaller. So the pixels appear the “merge” together making the photo appearing “clearer” (This is why smaller pictures sometimes appear clearer!)
However, the camera companies have made a bad decision to start this race because increasing the megapixel has a very detrimental side effect.
