What is HDR ? HDR stands for (High Dynamic Range), Firstly you should know about what is Dynamic Range, it is a condition when you click a photo with one side of the picture is dull because of shadow and the other side of the picture is overexposed due to sunlight and when you clicked the photo the camera couldn’t balance the dynamic range of the picture due to which the shadow side of the picture is very dull and the sunlight part of the picture is very white and overexposed.
Working Principle of HDR
And in the same condition now when you clicked the photo with HDR mode ON, so it clicks three images in which the first image is normal like the previous one, the second image is captured on very low exposure (Dark) and the third image is captured on very high exposure (bright) and now by the help of software it combines all the three images in a single photo by which photo becomes more accurate and the dynamic range of the picture is quite balanced and it makes image more sharpen.
Pictures Captured by With or Without HDR
When to use HDR?
- When you saw the landscape scene and you want to correctly expose the green land as well as the clouds in the sky, so in that case you should switch to HDR mode .
2. While capturing monuments or buildings, and if you want the structure as well as the sky properly exposed.
3. While capturing subjects with backlighting so this mode will help you to control the highlights in the background and the subject is properly exposed.
When not to use HDR ?
- When you are shooting silhouettes you should avoid using the HDR mode because to create a good silhouette you should make the foreground really dark with no details and the sky background may or may not have detail or be clipped as well.
- While capturing people or animals you should avoid using the HDR mode because HDR makes the skin tone very high in comparison to the normal which looks very horrible.
- While capturing moving subjects you should avoid using HDR mode because when you capture a single image with it so it takes three images and combines them in a single image so the thing is it a long process and it makes the picture blurred and Shakey.
