Yes you are right. After all photography is about limitations. Limiting the three dimensional world, in a given two dimensional frame and no matter what tricks we pull, this doesn't change!
A year roaming around Greece! That's a dream for me too. Fortunately I was working for a travel magazine for 3 years so I have a pretty good overview of the country but it's not the same. Loved to do a long road trip through the Balkans too!
