Flare or reflection problem (Temporary post)

Sorry, I'm using this post to seek some advices from the experts on a photography problem I faced. I'll delete this right after I get the solution.

Rome, Italy - Day 3 (Part 1)

This is a series of photos taken at just one place - Piazza Venezia. Crazy me!

And the dusk to night views, taken with my faithful IS lens, handheld.

Rome, Italy - Day 2 (Part 2)

In the mid day, we visited the Basalica di San Pietro...



This was taken from the dome at the top. A great view of Roma.


Inside of the main cathedral...


First sculpture of Microangelo, if not mistaken..heheee


Next, Castel Sant' Angelo.


Finally, Piazza Navona.

Rome, Italy - Day 2 (Part 1)

Roma Termini, the main train station...

Musei Vaticani, we queued up almost 2 hours for this ! Inside has the famous paintings by Microangelo - The Last Judgement and Creation of Adam.

The whole walkway full of paintings (and maps at the side wall)...

Two random paintings from the doom shape ceiling...amazingly detailed !

This is one of my favourites, a piece of colourful glass painting usually found in church.

More photos in part 2 of day 2 coming next...
