The Tourist-Cubism

How many photographs do you think were used in the composition?
- I think that there is about 30-50 different pictures in this composition.

Were all the photos taken at the same time of the day?
-To me it looks like these photos were taken at different times of the day, because you can see that there is different shadows on the buildings and roads.

Are there any obvious post-processing (Photoshop) enhancements?
- It does look like there might be some post-processing enhancements in the corner or middle of the pictures but it's not clear to see, and it might just be that the photos were taken at a different time of the day.

Any other considerations?
- I feel like this person tried to make the image look rustic, so thats why the photos are a little blurry. But altogether the photographer did a well job turning this piece into a cubic image.
