#290484 Microflash to fire optical strobes without using camera's flash

Posted by JohnLiddiard on 31 August 2011 - 10:09 AM in Lights, Strobes, and Lighting Technique

Build the circuit into a replacement for a cable bulkhead socket. That way you can convert a housing that does not have room for popup flash or any optical sockets to use fibreoptics instead of cables. Does it also mimic digital TTL? Or just manual?

#290434 Aquatica AD7000 and Inon Z-240 with fiberoptic, Settings?

I'm afraid that Jean is right in this matter, my suspicion is verified, unfortunately, I have no light meter, but how do I check the strobe in this case??
I think I've got water into the electric contect a while ago, could that have any affect?? I mean that the electric contact is shielded with silicone or rubber??


Swap the left and right over. Keep everything else the same. See if the effect reverses.

#273465 Spare Air - Any opinions?

Posted by JohnLiddiard on 30 January 2011 - 03:42 AM in Photography Gear and Technique

I'm now thinking about travel and diving elsewhere. I think a pony is a good idea for the UK but if I go elsewhere and they don't have pony options...

When overseas, most boats on a 2-dive trip give you a cylinder for each dive. Take a buddy twinning kit and a second regulator (the baggage weight increase is only really that of a first stage, as you don't need an octopus on either). You now have twindies that you can stretch over 2 dives. You can even use a bit more gas on the deeper first dive at the expense of a bit less on the second dive.

#267157 Are video people smarter than stills people?

Give me a video camera and I have this uncontrollable urge to turn it 90 degrees for a nice upright portrait shot.

#263637 Anyone uses knee brace under wetsuits?

Posted by JohnLiddiard on 14 October 2010 - 12:56 PM in The Galley: General Chat

I had a badly twisted ankle and did every dive on a week's liveaboard using duct tape to strap my ankle into a finning position and hold it there. About 3 wraps of tape in a figure 8 did the job.

I also regularly wear a back support under a drysuit.
