Dynamic Photo HDR... Many times you see a beautiful scene and of course you take a picture! The result is often far from being the magical scene you remember.
Our eyes are very adaptive and they are also more sensitive to intensity than color. The chip in camera is none of that.
It is estimated that our eye can see over a dynamic range of nearly 24 f-stops while a digital camera can capture a dynamic range around 6 to 9 f-stops at best.
For this scene we could set our digital camera to correctly capture the foreground or the sky, but not both at same time.
The High Dynamic Range Imaging is a set of techniques that has been developed nearly 20 years ago to overcome the limitations of electronic devices by combining multiple exposures into one great looking image.
Using HDR technique we can combine the different exposures to create a single image that shows details in both sky and the land.
A High Dynamic Range photography can be created by taking few photos with different exposure, then combining them in the software into a high dynamic file. The last thing is to tone-map the HDR image so we can see it in our screen, print it, post it on the Web and enjoy.
