I took this first photo from EasyJet flight #2888 today leaving Sardinia for Milan. The bottom one is not taken from the air, ha ha, but from the beach, and no it's not a perfume ad, it's Valentina enjoying a typical afternoon on Cala Golortizè in the Supramonte.
There aren't any fancy Photoshop tricks being used here (a little contrast tweak above to minimize the filmy look through the plane window...the below pic is untouched), Sardinia in August really does look like this. If it makes you feel any better, you can only get to this beach by boat or by hiking down a mountain for 45 minutes.
I'm suddenly kind of really busy with real life things I should be doing, but I'll try to get the whole story up here soon.
