It's always fascinating, for me, to see 'city-scapes' of a bygone era.
At my age I'm also able to recall 'then and now' photo's.

It's amazing how quiet the streets of Manila appear back then, although I'm sure it wasn't quite so.

I must say it's great to be able to get photo's digitised. The originals are always prone to deterioration no matter how well looked after.
I'm doing something similar myself with some old family photo's.
Need to learn much more about the capabilitites of Photoshop.

Good luck with your project Alan. Stick at it.
