DIY Ring for flashes in macro

Hi, guys,

I know this should be in the DIY section, but I will have to find time to explain how to do it. With some PVC pipe, you can have it done:

If your port does not fit the PVC sizes, you can take it to a machine shop, as I did:

Since Seacam does not have a security lock in the port, I opted for having the whole thing fixed on top of the housing for added peace of mind.

The knob on the left allows for fixing the position you choose (rotates 360 degrees)

Also note that with three balls you can mount also the focusing light, that will be always on top rotating with the flashes

Hope you like the idea.

Pretty nifty!

I love the idea and especially the compactness.

I have been gathering parts together for the Nexus port ring...

My only concern is that the strobe companies continually recommend

a minimum strobe to subject distance of approx 12inches?

I wonder if these ring flashes and associated port-ring strobes are too close

to deliver the required flash and the required 'quench' time???

Has to be the quench time driving the mininum distance thing in TTL Bruce.

Wonder if lower output strobes would be a better bet - Ike DS-50 ?

Either that or can manual exposure be that tough under these controlled conditions ? I mean you are tight in and with High F stops to get DOF, shutter speed not terribly relevant unless you are on the 'arty' background thing.

Hey Big Paulie,

I've been thinking about using the S&S YS27DX strobes...

I can fire them optically, and they have nine manual settings.

I haven't been able to get anyone to give them a really good recommendation though...?

Seems as if most folks think that they are a digicam strobe...?

I reckon that they could be a good unit in nice and close to the port, but hey, what the hell do I know...

Hi, guys

I do use the Inons in manual, controlling the left´s one in manual (the knob sits in the outer part of the flash so it is easily accesible) while the right´s one is slave, as you can see in the photo.

No problem with this configuration in shots with the subjet as close as 2 inches to the port (i.e. using a wet diopter)

I do shot regularly over f32 without problems with the output of the inons

Can not use them in TTL since my housing has the Seacam converter installed from factory for my Seaflash 250

No problems here putting the flashes super-close.

This isn't really a ring flash by the way - it's a ring to mount flashes onto. It's still a really good idea :-)

Athena from Japan makes a real ring flash for underwater photography. It only provides a manual control for the flash output and no TTL. I tried last week in Mabul and result is very satifactory. I could get really close to my object and had even lighting.

We have a ring flash from UK-Germany and it is TTL for the Canon 5D.

You can get very close to the critter and the only drawback is that you can see the strobe tubes reflected in the little buggers' eyes.

I don't have a photo handy to show tho...

Hi Hoover,

I did a little search on the web for UK-Germany without being successful. Can you give me their website?

Sure,

I'm really happy with the 2 housings and the ring flash we purchased.

BTW, here is a sample photo of a blenny taken with the UK ringflash

You can clearly see the flash tubes in the blowup of the eye:

Other than that it is a wonderful TTL unit.
