The video contains a small selection of my photos. All these photos show Unesco World Heritage Sites, except for the last photo from Namibia and the photograph of the Norias in Hama. The Norias of Hama are on the Unesco World Cultural Heritage tentative list. The photos are the result of playing and trying out with the camera and photo editing software to add some effects to my slideshows. I call them day-night photos. All these photos were taken during the last 20 years. I took several day-night photos from different places in one country. Each of these photos is from a different country. I have also taken many more day-night photos in other countries such as Mexico, Colombia or Peru which are still waiting to be presented. A photo set usually contains three photos, taken during the day, in the evening and at night. But sometimes there are only two photographs, made during the day and at night, like in this series, the photo I took in Iran, in Jordan and Syria. Very rarely there are four or more photos taken at different times, like in this series, the photo I took in Uzbekistan and in Israel.
