Roman sites along the Danube

[Caratacus]

But in the archaeological section the rooms are so dark, that it is hard to take good pictures. At the same time it is difficult to use flash, because the glass showcases reflect the light and spoil the picture. I admit that it is also partially my fault, because I'm not good in taking photos and do not know all the tricks how to use the camera in dark environments.

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.
