Pixel Binning = Better Low Light Photos?(Tech Explained)


We click lot of photos daily.But we always struggle to click a perfect photo when in low light.So we are always looking for a solution to click the best photo like using flash but we end up clicking blurry photos.So that is where pixel binning comes into play.So let's have a look at how we can use this technique to click better low light photos.

 To understand Pixel Binning we will have to first understand the camera sensor

 Understanding Camera Sensor
Unlike what we understand a pixel to be when we look at an image, the “pixels” on a sensor has a red, green or blue filter on top of it, allowing only the light that passes through these filters to be registered. These filtered pixels are laid out in alternate patterns, with green pixels being two times that of the red and blue pixels in any given horizontal or vertical line. The adjacent red green and blue pixels are combined into a single RGB pixel using a process called ‘demosaicing.’ The binning process takes place during the demosaicing stage, even before the JPG is generated.

 What is Pixel Binning?
Pixel Binning is a image signalling processor based technique.It takes place at the time of demosaicing process where it combines information from four pixels into one.For example that a pixel binning take 2x2 grid and combines them into one.The information captured by each individual pixel is now combined into one Super Pixel.The unfortunate result of that is the resolution of the resulting image is 1/4th  resolution of the sensor.The combination of data collected by 4 adjacent pixels into one “super pixel” is called pixel binning 

Benefits of Pixel Binning
Pixel Binning solves one big problem of  Low Light Photography. By combining raw data from four pixels into one, the effective output is a higher amount of light captured, while reducing the noise generated. Without actually artificially boosting the “signal” (amount of light perceived by the sensor, usually done by increasing the ISO), the resulting image is much brighter.Pixel binning is definitely a very smart way of getting the most out of a sensor, but there are limitations even to this implementation.

151 MP Camera :-Dope Tech Explained

A 151 MP Camera is something that we could  not imagine a few years ago.But this is made possible thanks to the company"PhaseOne".The PhaseOne XF IQ4 captures ridiculous amounts of deatail. So let's have a look at this Dope Tech. Phase One Camera Specifications Many of the medium frame cameras that try to capture photos above 100 mp use the technique of capturing multiple shots to up the megapixel game rather actually increasing the size of the sensor.PhaseOne however has turned up the camera sensor megapixel game with a staggering 151mp camera sensor that is backside illuminated The camera muster an ISO 50 to 25,600 sensitivity despite the extreme resolution, and you can use both timelapse and bracketing tools independently of the main camera body. The IQ4 also scratches the itch for pro photographers with XQD and SD card slots as well as tethering through Ethernet, USB-C or wireless. If it sounds ridiculously expensive... well, it is. The regula...

Thunderbolt 3 Explained

  The ports on the side of your laptop are important. They decide what you can do on your device and how quickly you can do it. When Apple introduced the first version of the new style MacBook Pro, Apple ditched every single port on its old machines and replaced it with just Thunderbolt 3.Many PCs have now followed suit into the world of Thunderbolt - although it's still relatively few that have gone the whole hog and dumped all other ports the same way that Apple has on the Pro and MacBook Air. So in this article let's understand what's Thunderbolt 3? What is Thunderbolt 3? Thunderbolt 3 is the latest version of Thunderbolt, and it uses the same design as the familiar USB-C connector. This connector is used for simplicity Intel introduced the Thunderbolt platform in 2011 at a time when USB 3.0 was all the rage and could transfer data at speeds up to 5Gbps. Thunderbolt was capable of twice that, plus it could transfer multiple types of data, not just serial data to storage ...

QR Codes Explained

We use QR codes daily for different things like making payments, storing your travel information, visiting websites, connecting to Wi-Fi networks. These barcodes can be captured using smartphones. So in this article let's understand what is a QR code and how do they work. What is QR Code? Qr codes were first developed by a subsidiary of Toyota 'Denso Wave' to quickly track vehicles and parts through the company's automotive manufacturing process.QR code stands for Quick Response Code. Although Denso Wave still holds patents over the technology, QR codes are free for anyone to use without a license fee as long as the intellectual property is being used within the defined ISO/JIS standards.QR codes are machine-readable labels — computers can understand them much more easily than they can understand the text. In 2016 for instance, Snapchat and iMessage introduced support for QR codes as a method of adding new friends, WhatsApp uses QR codes as a quick way to access the de...
