I ran across a royalty-free photo on Pixabay that I'd like to paint. This photo caught my breath upon seeing it. I love the light and colors, the boats in the foreground, and those beautiful buildings.
In this photo, I'm wondering if there is a camera distortion. The building with the dome on the left seems to be leaning to the right. The red building in the background seems to be leaning to the left. When taking the photo through my photo editing program, I can drag a grid line from the ruler into the photo and can see that the walls are not straight up and down on these buildings.
I'm not sure if this is camera distortion or if this is actually the correct perspective for these buildings. Perspective is something I'm still learning (as you can probably tell) and wanted to know your thoughts. I know about horizon line and vanishing points but have never tackled anything of this nature.
Here is the reference photo. Location is Cinque Terre in Italy.
Thanks so much in advance for your input.
