If you are in the field of photo editing, then you should know what is HDR Effect. In a simple term, this is a photo editing effect to make the photo more artistic! Sometimes, I use the copies of same photo to build a HDR photo in GIMP. Nowadays, there is a quicker way. There are some app make to do this job, such as an app calls HDRCamera in Android Market. You just need to open this app and then press a button to take photos. Just like your default android camera. Then it will do the job for you.

That is a quite good!
