luminance hdr user interfaceLuminance HDR is a free open source HDR software, that is specially designed to work with HDR photography. It is a standalone program that works on Linux, Windows and Mac operating systems. I played with this software for some time and found the result to be similar to image created using Photoshop or Topaz plugin. For getting the best result you still have to play around with tone mapping.

You can start making HDR by clicking “New HDR image” button on the top, this will launch the wizard where you can choose the images of different exposures. In my opinion, the process of creating HDR image is self-explanatory, and you will be able to create a HDR image without looking documentation. Below is the sample HDR image, I made using Luminance HDR. The image below is just an example, since I myself took the image using ordinary digital camera and the image below is made from single image i.e without using multiple exposure. This picture can’t be regarded as a best it can do but the result is pretty satisfactory and quick to make as well.
