camera obscura + model box potential?!

from this website showing principles of earliest image formation in a light tight box


for the shed as a pinhole camera/camera obscura- to demonstrate the process of image making ,taken from SCP website
need to think about use of pinhole/ or size of hole/ lens, which gives sharp focus on opposite wall of shed?

THOUGHT- do i want to make a pinhole camera and only devlop the image making it temporal, OR go with the camera obscura as the projection screen of the image formed is a temporal projected image? capturing the image on the windows of the shed OR removing part/whole of a wall of the shed. Usual camera obscure(eg Edinburgh) has a lens in the roof and image forms on a table inside it. Friend at university, Jack Griggs, that I have sadly lost contact with over the years, made a camera obscura for her BA show.

camera obscura- the band which i love (guess why i checked them out ages ago, and found music and name are both fab)- apparently recorded album at strongroom, 120 curtain road
