Roman sites along the Danube

Here's a trick you can try in future; you need to stand at an angle to the glass case. For best results, the angle should be at 55 deg to the vertical. At this angle, the reflected light will be 'plane polarised' (this is something called "Brewster's Law" in optics: the tangent of the angle of reflection is equal to the refractive index of the medium, for glass/air this will be the aforementioned figure of 55 deg.) If you have a polarising filter on the camera lens, turning this at right angles to the reflected light should see most of the reflections disappear but the reflections will be lessened just by taking the picture from this angle.

Thank you, Mike. I tried to take the pictures from various angles. Sometimes it helped, sometimes not much. I will have to learn how to use cameras properly, I guess
