I am currently playing around with hugin , trying to create good-looking panorama photos... It's not entirely easy, but maybe you'll get to see some of the results after my vacation.
Re-shooting "on the top, there are bubbles" proves difficult. I just didn't find the right mixture of soap and water and shaking yet to produce the right bubbles.
I also have problems recreating the exact position and angle because the flashlight otherwise just makes everything much worse.
