Some impressive shots from the inside of the Petralona cave. When we visited we had to take a special permit in order to photograph the inside and flash was forbidden.
I recommend you visit it.
We should also add that all the printed photos are clearly superior to the ones we upload. This is because the full resolution of the photo is larger than what the page accepts.
All photographic prints are numbered.
A4 and A3 size frames are wooden with glass, while A2 are wooden with plexiglass. Visually they are identical to each other.
