Well, *scenery* can be natural wonders or man-made artifacts. Personally I think that the man-made items are more unique in Europe.

Can't comment on Santorini - but I would think you're missing the Alps (Switz for preference - or German/Aust).

Lots of areas besides the ones you mention. There are the Alps, be they Swiss, Austrian, German, Italian, Slovenian or French.

And even the flatter areas can have beautiful scenery; it's all in the eyes of the beholder: http://www.flickr.com/photos/mksfca/4529705832/in/set-72157623877915948

What type of "stunning scenery?" Landscape? Architecture? Still life? All three cities you've mentioned will fit the bill. Many of our Fodorites have taken amazing photos in Prague.........

Your other thread shows that your thinking is all over the place. Honestly, you can take amazing photos in most any country. The best photos I've ever taken in Europe were sunsets on the west coast of Scotland, followed by night time shots in Paris and day pix in Venice. But I've sold photos taken in probably 10 different countries.

Since London/Paris/Venice are on your wish list - that is 10 days to 2+ weeks worth right there. With your other two-ish weeks you could spend all of it in Italy, or a few more days in Italy and a week or so in Greece. OR you could go to any other country that sounds interesting.

You and your friend can take BEAUTIFUL photos in any of those places.

But what won't work is all the travel and one night stands and multiple hops you were considering.

After 28 trips to Europe I totally agree tha

Sorry---big thumb!

After those 28 trips there is no doubt you can take awesome shots in most locations. My favorites have been:
Sicily
The Dolomites
The Dalmatian coast
Venice
Tuscany hill towns

Instead of focusing on places where you can take stunning pictures (which is, frankly, anywhere), I'd focus on where you'd like to go. Then get there and figure out the photography aspect. And keep it to a small list, not that all-over-the-place approach you began with (which is understandable, but totally impractical and won't even allow you to get out the camera equipment between stops).

Too ambitious, too many places for 28 days, you need time
to find the places for your shoots, you need to savor the foods of the places you select.These things will make your photos more meaningful. I think two choices are plenty.
For instance, forcolor, Provence is a must. You will have Paris as a city to be photographed if you can do not the usual you see on everyone;s travel sites or the postcards,
bon chance.

I too like to take photographs, and I find it easy to slip into the "other places are so photogenic" mindset. So sometimes, I pretend I am a tourist in my own town and take a walk while I imagine what I would like to take a picture of. Or I set myself a task of taking a different photograph every day for a month. I also go to photo websites to look at travel pictures for inspiration. Trouble is, every place looks like a great photo op. My list just gets longer and longer.
