My GoPro 3D setup

[3D diver]

do you have any video with this yet?

No, not yet, sorry. Local dive conditions are poor & I'm up to my ears in work (was in the office yesterday).

I got these puppies (the white steel 120's) VIP-ed & filled Saturday, though, and am hoping to get a dive in soon.

My expectation is the 60 degree spread will yield a noticable light circle that I'll have to either live with, or address by adding more lights.

For using 2 Darkbuster HID flashlights as video lights, I used the plastic sealer on yogurt cups as diffusers. Worked quite well and less than cheap. The bigger problem became getting a constant color temp from the flashlights...

I like the diffusers in post 25.

I'm very pleased with the holographic diffusers. The light was noticeably brighter than the opaque white diffusers used during my last dive. With diffusers in two lights the light spread seemed adequate---I only had to re-aim the lights a couple of times to compensate for different subject distances.

Finally figured out how to pull single frames from the Pinnacle editor. Here are a few shots from my last dive.

These first few were close enough for the lights to be effective:

Heres a shot of the sealion that buzzed us:

and a few jellyfish shots:

Going diving again tomorrow.

3D: Is there any reason why you picked the holographic diffuser over the other diffusers WaveFront had?

 

[3D diver]

I would have to go back and refresh my memory as to their other offerings. Basically, I called them, described what I was trying to do, and this seemed the best match and was readily available. I wanted a circular diffusion pattern (not rectangular) at as wide an angle as possible & as high a light transmittance as possible. The thin sheet form factor is better 'cause it is easy to cut and fits withing the light (important since the film itself is fragile).

Ah, okay. I can imagine why since I briefly skimmed over the descriptions, and they said that the holographic would aid in 3D recordings by creating a 'sparkle'.

I really want to use the holographic since it seems like the white diffuser blocks out a lot of light. How much did it cost to get a sample of the holographic?

 

[3D diver]

Well...don't get distracted...most of their films are glittery stuff for packaging/gift wrap. There's no sparkle in this film.

They charge $35 for the sheet I got, but gave me mine as a sample (and they paid another $25 to ship it to me!). Give them a call and see what you can get. If you do order a sheet you might suggest they mail it to you in a simple cardboard envelope, their normal packaging & shipping method is overkill.

I recommend you try the white diffuser first, though. You'll be impressed by how much it spreads the light, and it's dirt cheap to make.
