take this picture:
imagine the pencil was a small sun
actually wouldnt be posible to project the sun in a tiny spot, according the projection rules you see in that picture, for you just can make it more clear or more blurred by changing focal distance but not bigger or smaller in angular size from the lenx apex, according the projection rules you see in the picture it will reverse with identical angular size however focal distance
oh and in the web there are plenty of pictures of the sun i gues its a matter of set a very high shutter speed
edit:
theres a way to see a light shouldnt posibly be more concentrated that its angular size in photography, yet you can project the sun this way with a lens in a tiny spot :
if you unfocus your eyes while looking at the screen led it will grow and blur, it doesnt matter you unfocus by looking closer or farther, the smallest brightest led you can see is in right focus
so as you can see a photographic camera as the eye follows different rules than if its open like a lens concentrating the sun on a paper
edit:
well so when i concentrate light with a lens lights waves as young experiment, following wave projection rules which i gnore
but when light is observed it becomes particles, following the classic projection rules for straight lines
so just when light enters the eye becomes real,no observer nothing at all
just think if in the double slit experiment instead of a measuring device to tell which slit did the photon go trough you could just get a guy looking and telling what slit brights when the photons shot, you could put a transparent photosensible sheet and it should give away two bands
so observer getting photons within the eye, particle, two bands
no observer seeing the light within the eyes, wave many bands
