lens reflection methnks

can a lense make that big a reflection?
I got a pic somewhere here where we've got a rainbow on the roff, i'll see if i can find it

if it were a lense prob, it would continue through the shadow, wouldn't it? --- VH16

no it wouldn't, and the lens was my first guess. and the rainbow wouldn't continue through the shadow becasue:

shadow = photographer of pic, he was apparently looking down.
lens = behind photographer, hence, rainbow and image was formed on the ground, and where the shadow was, blocked out by the body of the photographer.

im thinking a flash trick with the camera, but then again who's gonna know its gonna happen at that instant? and iirc, rainbows made by flashes have a explosive effect to them, like light is exploding out from a circle. i've never tried it myself though. i have to say its most likely to be a rainbow formed by an optical instrument, most likely refracted, but not ruling out the possibility of a reflection if anyone can come up with a good explanation as to how that was achieved.

im going with a huge lens behind photographer in direct line with the sun, turned just so to produce a circular rainbow.

keep in mind: red is refracted the least, and should be in the inner edges of the ring, if you were using a relatively small lens, size of your palm or so. but it is on the outside. so how is it going to be refracted like that? a huge lens.

i may be terribly wrong here as well, for i dont have a huge lens at my disposal.

Im guessing lens flare.

im not acquainted with photography terms that much.. care to explain ?

Its not the lens, if you look closely, you'll see the rainbow behind the shadow as well, which means the rainbow is caused by sth behind the guy who's shadow is there

Breaking it down into the obvious, here's what I see. I thought I'd put this out here to see if someone else sees something differently.

If I think only about possible sources of the light, I find myself thinking that it is an artificial source from origin onward or natural light that has been reflected/refracted by special surfaces. Either way, I don't think that what we see is direct sunlight.

As for the surface, the visual light effect to me at least is generally inconsistent with what appears to be some form of pebble/concrete amalgam unless that amalgam has been polished/treated to make the surface much more smoothe.

Because the figure blocks out parts of the rainbow, it implies that the figure is standing in front of the light before it shines on the wall/pavement/shiny surface.
