How to make a photo better | Smartphone HDR explained

Whenever you open your camera , you've probably come across a term named HDR , but what exactly does it do and how does it do that ? Read further to find more.

HDR stands for High Dynamic Range . It tries to make a balance between highly bright side against the lower bright side of the photo. Sometimes the photos tends to get over exposed in one region and under exposed at another , HDR tried to solve this problem by taking not just one photo, but three of them and stitching them together.

The first photo is your regular photo you've taken, the second one increase the exposure value to the maximum and the third one reduces it to the minimum. Then with the help of software tricks it combines them together to produce a photo which preserves the details which was blown away by the over exposed region and brings light to the under exposed areas.

In the first image, the shadows are a little washed out and the image looks dull. But when HDR is enabled (the second image) , the image is brighter and shows off the seperation of individual leaves better.

But there are some drawbacks using an HDR processed image
1. As the camera processes three images at a time , it takes a while to process them and produce a output (couple of seconds more than your regular photo)
2. As the image takes so much time to process , the resulting image might be blurry and loose the information due to handshake
3. HDR is mostly a software enabled feature , so there needs to be a lot computation to be applied . Most of the times the software might not end up giving the desired result as the photographer wants.

 At the end , if you are a snapchat'er or any social media uploader who wants the best from your smartphone sensor and who is willing to have steady hands for a while , this feature is really handy .On the other hand ,if you are the kind of person who wants to edit there photos on a professional software , there are many alternatives than this toggle.
