To access to the upper floor of the inside of Hagia Sophia basilica, you have to go through this hall that leads to the stairs. The light reflecting off the window in front of the chandelier and soft lighting makes in this room an enchanting play of light. I made this HDR handheld because in Hagia Sophia you can not bring any kind of stands inside. I had to wait several minutes for anyone who does not pass in this room, it is a must to go upstairs.
Usually, I use a tripod to make my HDR photos. The use of a tripod for this kind of photography is important for the clarity of the images, to align themselves and to avoid blur. The main reason people recommend a tripod with HDR works, is the difficulty getting the 3 images to align properly. However should be considered that is not always possible to carry on a tripod, in all these cases you can still make a HDR shooting the exposures series holding the camera in your hand.
