Help needed from experience guys who have used snoots... I have recently bought snoot for my 300 watt strobe (brand aurora). The images here show what is happing. I expected a circular spot like light from the snoot but instead i'm getting multiple circles embedded inside each other. I believe this is not how strobe r supposed to work as I expect a single circle of light.

Are my expectations wrong? is something wrong with how i'm using it or with the snoot itself? is it the way snoots r supposed to work or wat? Any help appreciated! Thanks in advance.

Yes, that is what to expect from that kind of snoot. It is all about the design and the optics. You probably would like the effect of grids in a standard reflector. Or for a really controlled looks a Fresnel spot or optical spot. These have actual glass lenses to help focus the beam.

It is also possible to buy a plastic Fresnel lens from Edmunds Scientific and make a box for it from foam core and use that on your standard reflector.

The type of snoot you bought is just to apply light to the back of someones head.

thanks for reply kgphoto... this sounds bad.. but then how come the light pattern of snoots shown in brochures of brands like Hensel is so focused and without extranous circles. Because in this case, even as a hair light there will be too much spill.

Anybody else who can comment?

You may be able to roll a piece of seemless and get more what you're after. It won't be focused like a fresnel but it won't have the gradations I see above.

Its not really possible to tell what the pattern of light is on the background with your two sample photos because you're getting quite a number of interference patterns (like in quantum slit experiments) from the light that leaking around the edge of the flash head and the snoot. One thing to try is to use some black foil or even tin foil to mask all around the area where the snoot connects to block off light leakage. I use snoots on some of my flashes and I do not get the effect you are showing.

Cheers,
rfs

This is going to sound like a dumb question, but what color is the inside of the snoot? Is it white by any chance?

It looks like the way that snoot is designed that it steps down as it gets smaller. I would suspect that's whats causing the rings. Try rolling up a sheet of dark paper or cinefoil and putting it inside as a quick test. Don't leave the paper in there long if there is a modeling light. Just use it as a quick test.

Fredrick, this gradation is the problem itself. I tried coverin the edge of flash head where it connects with snoot but still gradation is there. if u dont get the effect with ur snoots, then perhaps the problem is that aurora is a trash brand...
Rob, the color inside is silver. not a dumb question.
Mark, I think all snoots r designed to step down and same here but I *think* it shudnt cause rings. Even tho thats wat the dealer is telling me that these patterns are due to the "snoot design" and not a fault. if my step down snoot is causing these hideous rings why isnt the snoot Fredrick uses does the same? :-( or for that matter any snoot light pattern in any brochures that i hav seen. Fredrick ur snoot is the same stepped type one? right?

It is a low end design. If you want a better one, take this back and get one that you like.

I thought so. The the light pattern that you are getting is caused by multi-path reflections off of the interior "steps" of the snoot. The interior should be non-reflective. Try painting it flat black.
