The thing about the sidewalks of Italy is that there is only room for one person wide while walking. This wrecks havoc with stopping to take pictures since anyone trying to pass you has to step into traffic. There is never a time when you are alone on the street so if you stop for any reason there is a lot of risk involved. I am quick at taking the gorilla type shot with the native camera on the iPhone, but I haven’t risked HDR shots except when I know that I will not be risking anyone’s life. You have to stand absolutely still while the Pro HDR app analyzes the image and then takes two images and blends them together. These are HDR shots I have taken when I could stake out firm ground and clear vistas.
