Any feed back on Glowdive strobe diffusers?

I have recently seen these domed shaped strobe diffusers for sale and was after any opinions of them.

They seem to give a softer more even light that could be handy but also that they reduce backscatter.

As with most things in this game they are far from cheap for a couple of bits of plastic so I thought I would see if anyone has any experience using them before I bought any.

Thanks for your time.

As you say, bear35, they do indeed seem far from cheap for a couple of bits of plastic!

I use Inon Z240 strobes and always use the diffusers that come with them - but they are not dome shaped. I'm not sure though whether having them on or off makes a great deal of difference and certainly doubt that it makes a difference in terms of backscatter.

Would it make a difference if they were dome-shapped? Hmmmmm...... I remain to be convinced.

Anyone got any examples they can share?

With a dome diffuser such as the ones for SEACAM strobes one can cover the near field of a fisheye lens. I have thousands of shots done this way with one strobe mounted at the 12 O'clock position. I have also shot the same fish eye lens with an Inon strobe with the Inon flat diffuser installed - earlier 220 model that is the same size as the 240 models. The corners come out dark unlike SEACAM. My conclusion is that dome diffusers are superior to flat ones at least for fisheye lenses. Adam H tested one a while back but good luck finding the test on this site.

Here's Adam's review of the Clark Miller Dome Diffusers:

Couldn't find it using Wetpixel's search function but Google came up with it.

I've been using them for a while now and like them.

Thank for that Gudge.

Probably asking too much, but has anyone actually done any shots underwater to highlight the difference between using the domed diffuser and flat?? Particularly what effect it has on backscatter? As I understand it because the light is emitted from the curved surface it hits the particles at a different angle and doesn't show up.

It seems odd to me, the company I previously mentioned have done all sorts of land testing shots on their literature but nothing underwater...

Sounds good Tom_Kline... Are the strobes (i.e the Inon v Seacam) you mentioned the same output?

The Seacam is more powerful. I can get backscatter with either design.
