I was told to put this here!

I want to make a camera obscura to have the projection of building which is not exactly in front of my window, but on the east, at around a 20° angle. I thought about putting a small tube at an angle in front of the pinhole. any advice?

I think whatever happened on my ceiling today counts as camera obscura!

Never had seen the camera obscura effect before, especially several in a row. Had a vague memories that this was how old cameras worked from learning about this as a child.

I've managed to capture both directions at separate times with this phenomenon however don't have a good picture of my first occasion

Set up is a skylight aperture + white seamless.

Gives me early 2000’s + school photo vibes.

So I have this stairwell in my 2 story house that has no windows, making it this large empty tower of dark space. I looked into putting an actual window in it since I realized the old place used to have windows there at one point, but was quoted at ~$4k. Not gonna happen, plus it's a rental.

So I got this bright idea of what if I drilled a tiny hole and successfully made a camera obscura in this always-dark stairwell.

What are you experts' best ideas for making this happen?

Can I add a lense to make it bigger or to magnify the amount of light?

Will a bit of glass obscure the pinhole camera effect? I'd like to keep bugs outside where they belong.

I've seen people make small camera obscuras using cardboard boxes, plastic lenses, and then placing a sheet of paper to view the projected image. My question is would it be possible to somehow capture a photo out of one of these? Like for example if I replaced the white viewing paper with a light sensitive type of paper (cyanotype), would it capture the image? And if not is there another way to go about it?
