I have been meaning to photograph the Madeleine cathedral properly, for years.
(Properly = with a tripod.)
In fact I think I did do some photos, once, with my conventional film camera-- years ago.
I find it is sometimes very hard to do local things.
It's easier to make time to do things on vacation, when the window of opportunity is short, but focused on extraordinary events.
Anyway, what finally got me up to the Madeleine was putting it on my syllabus for my Gothic Revival class.
Now I am teaching it, I need some decent photographs.
So, with a little help from photoshop and, of course, the tripod, I got some helpful details.
