You really need to check out the before image to fully appreciate this shot. The only natural lighting is coming from those two lamps on each side of the door. As you can see from the neutral (0) exposure, the lighting didn’t add a whole lot of mood or color variation to the scene, unless flat and yellow is a mood. In that case, winner winner, chicken dinner… Jeez I get sidetracked easy…
So, my advice to you is: when you shoot HDR Photos, try to recognize the potential of a scene not for what it is, but rather for what it could be. Try to pre-visualize what it will look like after you apply all of the Post Processing.
In the case of this scene, It might be a good idea to cross your fingers too, because looking at the before and after comparison, it’s literally night and day. Well, it’s technically night and night but you get the idea.
