The first thing that comes to your mind when you hear the word HDR is “that cool option we find in most smartphones which captures great colors”. That is exactly what HDR is. It’s a technique in photography which enables you to capture a greater range of colors. To start off, HDR simply means High Dynamic Range. You must have been in a beautiful location, clicked a picture and then realized that the picture was flat and disappointing. With HDR processing, your picture will look as enthralling as it was when you were at the beautiful spot. Here are few examples of HDR photos.
Why HDR ?
The human eye has the capacity to see a greater range of colors than a camera sensor. A typical camera sensor can capture about 3 stops of light. But a human eye can capture upto 11 stops of light. Using a combination of your camera and software, you can make your photos look the way your eyes see things.
How is it done ?
A typical HDR image is created by combining more than 1 photograph taken at varying exposures. In simple words, you use an underexposed, overexposed and a normal photograph taken of the same scene and combine it using software.
What do you need ?
- Any camera with a manual mode
- A computer
- An HDR processing software like Photomatix Pro
- Adobe Photoshop
- A little patience
My next post would contain a step by step tutorial to create HDR photographs. In the meantime, here are a few more HDR photos.
