I am going to create HDR Imaging tool using java for my Image Processing project.Can anyone give me a help regarding this area.......???????

In the future you better do some research and come up with some possibilities how to tackle problem instead of saying here is my idea hey do research and tell me what is bad. So next time please ask specific question
3years back I used Java Advanced Imaging and Java Advanced Imaging Image I/O Tools when I was doing TIFF to PDF conversions and some basic image info stuff. However since then there was a rise of interest in the area as you can see from this post @stackoverflow
