Pinhole Camera

An example of image formation using no lenses or mirrors!

[@bodudas8346]

All of the other tutorial videos instructing how to make a pinhole camera never address the most important question.... 'What is the optimal diameter for the actual pinhole?.' And that of course varies depending upon the length of the camera. Thank you.... you addressed and explained that exactly. There are so many different diameter pin hole lenses on the market.. now I know what size to apply to get the best image. wonderful video Bo

Thank you so much, I understood the concept so fast once you explained it. For whatever reason I knew of ray optics but I couldn't translate it to a pinhole camera situation.

That's not surprising; there's no lens! It's unusual enough that almost everybody gets stuck on it. I'm glad the video helped!

This is cool! Yesterday for the eclipse I built one. I wanted a bigger image and dug a bigger hole... Which you here clearly explain won't help, it will just make the image more blurry! Hey, am I able to actually see the true sun shape because the amount of light that goes through is so reduced? Next time around I'll be better prepared (in 2044). Thank you!

the most informative and practical video about pinhole cameras

[@robertcruikshank4501]

Thank you very much! It seems to be one of the topics that falls through the cracks so there isn't a lot out there on it.

Was a nice video, thanks

I linked the theoretical approach. I observed a similar effect on the edge of an obstruction. Looking past a straight edge it seems that letters are clearer close to the edge in the penumbra area. Is this possible and is it similar to a pinhole?
