What do you use to reduce flash beam?

[Mikel 0]

Hello,

 

 

I am thinking of putting something in my flash to reduce its beam to have more selective light. I have no found anything to put in it so I think this is a DIY proyect.

 

Searching in wetpixel I have found little information about that. And just one article about that in UWPM, in the 24 issue.

 

 

My idea is to adapt a piece of PVC to my flash:

 

 

 

Any other ideas?

 

Do you use or have ever used it? Pros and cons?

 

 

 

Thanks a lot,

 

 

Mikel

Hi Mikel,

 

Good job with the English. The device you are talking about is called a "snoot."

 

For something simple, you can cut off the arm of an old wetsuit and use it in this way.

Thanks James!

 

 

That is what appeared in UwP 24, a flash taped. I am not sure but I think that is not the best way to make a "snoot". Do you use like that?

 

 

My "idea" is something like this:

I also have read that with a kind of honey comb, the light is concentrated too and you don't need a long tube to reduce the beam:

The problem is that I do not know how to use/adapt it underwater and how it will work.

 

 

 

A good example of the result of what I am looking for:

A sandy area where you don't want a lot of light.

Mikel,

 

I know what you mean - sometimes you dont' want to light up the background.

 

You are on the right track. You can buy something called "egg crate" to make a grid for the inside of your snoot - to further help you control the light.

 

Cheers
