Yesterday, I found on the Internet a new kind of images called High Dynamic Range (HDR).

I read before about these images, but I think that these images have been taken by a new kind of camera.

Only yesterday, I discovered that I was wrong.

Frist of all, I want to introduce to you these new kind of images.

HDR images are very beautiful pictures.

These images imitate your eyes.

When we look at any beautiful sight and try to take a photo, we notice that there is a very big difference between a photo that have been taken and a real sight we see by our eyes.

The problem comes from, when we take a photo, we take a photo with one exposure only (brightness of photo).

Your eyes more powerful that any camera.

To solve this problem and make your images more beautiful, you should use HDR images technology.

HDR images is an image processing to combining many images in one image.

These images have a different exposure and same sight.

In iPhone mobile, there is a setting you can set to make your mobile phone take three photos of one sight but different exposure.

You can then transfer these photos to your computer and use software program like Photoshop to produce the HDR image.
