What Is a Megapixel?

 


If you’ve bought a new camera, smartphone or action cam’ recently you’ll inevitably have stumbled across the term “megapixel”, or MP for short. But what is it and why is it so important in the world of photography? We explain all in this guide.


What is a megapixel?

Megapixels are the number of pixels that you can capture in one photo. A pixel is the smallest unit of information in digital images. It is a combination of red, green and blue dots called ‘sub-pixels’.

The number of pixels determines the resolution of an image, also known as its size or scale. A high megapixel camera can in theory not only capture a detailed photo but it can also help you crop your shot without losing clarity

Do more megapixels mean better images?

Although Megapixels are a big part of the camera specifications, they don’t necessarily make the best photos. A camera with fewer megapixels can produce better pictures than a camera with higher numbers, because each pixel is larger. This means that more light is being let in and the picture is brighter.

When looking at specifications, make sure that you check out more than just the megapixel number. There are other factors that play a role in the quality of images, such as the size of the sensor and the quality of the lens.

Why is Megapixel important in mobile phones?

On a phone this is exacerbated as the device’s form factor limits the size of lens and how much light it can take in. Since you’ll likely want to share these pictures on social media, having too many megapixels can actually be a disadvantage.

If you try to post a high-quality image to Facebook, it will appear pixelated and fuzzy. This is because Facebook uses a lower resolution when you upload a photo, so that it loads quickly and everyone can see it. In order for higher-quality images to appear as intended, you’ll need a camera with at least 8-megapixels.

You can see examples of the above in our best camera phones guide, which includes a number of handsets with lower megapixel main sensors.

Which is the best resolution for Videos?

Megapixels work slightly differently for videos. For videos, you want a low resolution. When capturing video, you have to consider the megapixels that are used for each frame. If you have too many megapixels, you will end up with a low-quality video.

It’s important to remember that more megapixels doesn’t always mean better quality. If you don’t know what you’re looking for when shopping for a new camera, keep these things in mind. A higher resolution isn’t always better, and you don’t necessarily need the highest number of megapixels in order to get good results.

What Is Satellite? How Does It Work?

  How Does It Work? Table of Contents What is a Satellite? Anatomy of a satellite How does a satellite communicate? Bandwidth and Transmission Suggested Reading Satellites communicate by exchanging electromagnetic waves, either on the Earth’s surface or in space, hovering above a pole or orbiting us everyday. Communication doesn’t necessarily have to occur in the Radio spectrum. Your TV remote communicates with its set top box with infrared waves, while phones communicate with microwaves. Google Earth provides you the opportunity to visit any place on Earth, yet what do most people do? Look at their own house. In fact, Google Earth doesn’t just show you high-resolution pictures; like Scrooge on one of his ghosts, you are practically tossed there, as you can witness walking pedestrians and live traffic! But how does Google Earth achieve this feat? With satellites! What is a Satellite? The word satellite doesn’t necessarily describe a mechanical box floating through space with...
