Half-in - half out dome shots

What's the best way to break down the surface tension of the water droplets on the part of the dome that is half-out of the water?

Thanks

Andy

If it's a glass dome then Rain-X works best (it will damage acrylic). If it's an acrylic dome, pledge (furniture wax) or spit.

Sorry, I should have said it is an Aquatica 8" acrylic port. Thanks for the tip.

I've just bought some Pledge that has 5-15% aliphatic hydrocarbons as well as 2-bromo-2-nitropropane-1,3-diol, perfume, Limonene and linalool. I guess this is not a wax product as it says on the bottle "No wax build-up"

I've always been a bit worried about contaminating the sea with hydrocarbons and so on. Spit is OK, but who has enough for a big dome?

Since good over/unders are taken in flat calm water, the solution is obvious: keep the dome out of the waves until you shoot!

And the real solution for the 21st century? Shoot three or four frames and use photoshop to assemble an image without annoying droplets!

Both assembled from 3 sequential images taken in choppy conditions. I also think that a few droplets add artistic verisimilitude to an otherwise bald and unconvincing (visual) narrative viz WS Gilbert...

I'm shooting fast moving (sometimes) puffins mostly from underwater but am hoping to get some over and under shots as well. Just need a product that breaks downthe surface tension. Someone has recommended car polish.

Mikes point?

I've personally found spit to work the best. I even tried Rain-X for the first time last week (on a glass dome) and it did not work as advertised, so i ended up spitting on the dome at the last minute and it worked like a charm. Ill try Rain-X again, but it actually made the droplet buildup worse, despite everyone's raving about it including the lady in the store who uses it religiously on her car.
