For an end-of-year project when I was 16 I explained what a camera obscura is, showed that you can take photos with a shoebox, developed the negative and then obtained the positive digitally.

I just wanted to share that here.

The first photo is of my brother on the rocks in front of the sea.

The second is of the Costa Brava (Mediterranean) coastline in Spain.

The third photo is in the same place as the second, the subjects are my mother, my father and my brother.

(I haven't found a photo of the shoebox in question, I'm looking for it and will post it when I find it.)
