Yesterday, my friend bought a cell phone , which had this
amazing feature of HDR mode in camera. HDR is high density resolution imaging
hence acronym HDRI or HDR. This radical technology is used to capture images
with high variation of contrast, brighter and darker sections in the same photo.
The desire for such mechanism has been long recognized .Even CS2 introduce the
merge to HDR function in 2005. With this technique now even a novice photographer can take life like pictures without even turning the exposure setting . If you feel like having softwares to do that , you can some in net .Like
are two such stand alone softwares but they might not be free and u will have to pay for them.
In normal mode,
camera takes only one image at a particular aperture mode, so it might lose the
detailing of the darker and brighter section. IN HDR mode, the camera takes
multiple images of different exposure levels. Then combine them together
maintaining more details of the scene and making it more real like. The main goal is to make electronic picture have more color range and dynamic as our human eye see them. The HDRi data format is a 64bit (color) or 32bit (greyscale) data format for saving RAW data of HDR scans, hence the quality.
The picture below is taken inside a shop with glass windows , with a cell phone .
Due to sunshine when picture is taken without HDR mode, it appears picture 1. But
when the same image is taken with HDR mode, see the difference in it. You can see
through the glass (cars and some people).

It works well for the
pictures where a source of light is between you and your picture .Like while
capturing skyline or horizon. It’s great to see cell phone manufactures taking
camera quality in their phones to next level.
Keep Looking …
