8mm fisheye, backscatter

Hi all,

I'm getting quite a lot of backscatter at the side when using the 8mm Olympus fisheye, even when I point the strobes significantly outward, away from the dome.

Could my strobe arms be too short? I was using one segment, I believe 8".

Also, as I'm using the new Inon z-330, maybe the dome shades will help?

Strobes should be about same distance from housing as subject. If subject is more than 8", you probably need a double arm. Strobes should be behind housing. Strobes too far forward will cause backscatter or flare. In poor conditions, with silty water or plankton, try increasing ISO and lowering strobe power for less reflection.
