Better late than never

Ok, so I have been slacking.  You can thank Mass Effect 2 for the Xbox 360 for that!!  LOL 

I finally got some work done on my HDR experiment.  For those of you who dont know HDR (High Dynamoc Range) is an imaging technique that was developed to more accurately represent the wide range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.

In photography this is achieved by merging several images of the same scene shot at multiple Exposure Values (EV) to help being out all the little details the camera may normally miss.

I decided one morning to shoot basically the same image of my building at different settings so i can see how the different EV settings will effect it.

This image was created with three images shot at -.5, 0, +.5 EV
 

The next image was created with three images shot at -1, 0, +1 EV
  

This one was created with three images shot at -1.5, 0, +1.5 EV
  

And finally, this image was created using three images shot at -2, 0, +2 EV
  

None of these images are perfect, they were just shot quickly without using a tri-pod.  Here is my latest HDR image shot at Hayden Falls park in Dublin.
