Can my smartphone replace my camera?


No matter what it belongs to – Computer, Camera, Smartphone, Television, Music player or anything else, the fact of the matter is that every innovation has changed our lifestyle and made our life easier and more convenient than before. But technology moves really fast and raises a gamut of relevant questions. For instance, can my camera be substituted with my smartphone? Likewise, how many megapixels are required to have a high quality picture? Let’s begin with a key factor – Megapixels – which may answer these questions for you.

Similar to the concept of calories, megapixels are related to the measure of quantity, and not quality. Though quality is a complex matter based upon camera’s engineering, firmware, image sensor design and optics as well as pixels but not the megapixels count. At the heart of your camera, lies an image sensor that has an array of pixels working to collect photons or light. Having a clean and low-noise picture is actually dependent on the large image sensor that comes in different sizes. A larger image sensor results into larger pixel.

Now-a-days, mirror less cameras, advanced compacts and professional DSLRs are available, that offer larger sensors. These range from a postage stamp (APS) size to a comparatively very large full-frame sensor of around 1.5 x 1 inch (found in DSLRs). For instance, an eight megapixel DSLR will produce far better images than the similar megapixel compact camera.

Can You Have Too Many Megapixels?

Labeling a device with too many megapixels is more of a marketing ploy. In fact, it can deteriorate the on screen quality of an image. The reason behind this concept is that when you upload a heavy picture on social media, your picture will be downsized automatically. In other words, an upload process or application will randomly delete pixels that are critical for the picture.

When Nokia launched a smartphone with 41MP, professional photographers were intrigued. (Most of them are using Pro DSLRs like 22MP Canon 5D Mk III or the Nikon D810 with 36MP.)  The original reason for pro DSLRs to have too many megapixels are Billboards & Magazines. More Megapixels allows higher-quality images with more details, accurate colours and an improved ability to capture light which look fantastic on huge billboards and magazines.

How Many Megapixels are required for Social Network Photos?

With the count of megapixels going higher and higher, at some point they stop being useful and just become a number for show. But if you never plan to print your images, the requirements of megapixel will be much lesser than expected. It is impossible for naked eye to tell the difference between a photograph taken at 8MP and other at 100MP on social media websites. For example, a Twitter image, measures of 375 x 375 pixels, which is equal to mere 0.15 megapixels. As far as Facebook timeline image is concerned, it is of 960 x 720 pixels or 0.69 megapixels. However, Google+ provides one of the largest pictures. A 2.53 megapixels cover picture can be uploaded on this social networking website.

In addition to how many megapixels are required to capture a good picture, professional photographers are usually careful about how they compose their images while making sure that the all space in the viewfinder or screen is actually filled with what they desire to capture before they click on the shutter button. So, you should remember that the quality of an image is more important than quantity of megapixels to have good-clicked image!
