I totally agree with you that you need to capture your perspectives, as unique and as abstract as they might be, but you also need to capture that generic postcard image that everyone else gets too and why, because it's YOUR postcard image.
Sometimes too, if you only see and capture those cool looking abstracts and show them to people, then to those people it's a wall, door, street that really could be anywhere in the world, unless it's got unique architecture in the photo that enable the viewer to know where you are, whereas for you, that unique abstract is a memory and those memories, can last forever.
Just that first glance at that simple wall 30 years later and instantly you are right back there crouching, leaning, focusing to gran that shot, smelling the aromas and hearing the sounds around you.
And they are all quite distinctive shots, so I think that you captured that variety!
Fantastic. I can't wait to get to Italy one day. Thank you for sharing!
