Here’s the link to my first GigaPixel pano: View of London from Greenwich

From this picture: 

Over twenty zoom images combine to make this huge picture

You can zoom in this far:

With 100% zoom you can see HSBC written on the tower.

I have just been lucky enough to get taken up to the top areas of Tower Bridge that are not open to the public. Unfortunately there was not enough room to get any large panoramas but the views were incredible!

Looking West along the Thames

This was taken a few days ago - Nov - from Canada Square. I have not done any retouching to the image, the colour of the sky is as it was, the lights of London.
