Lumix Coolpix Triggerfish

Whenever we do the yearly Bluescope seagrass monitoring trip to Westernport I take the tweaked Coolpix 5000 housing with the Lumix LX3 fitted. Jan always likes to spice up her report with some photos of the colourful marine life under the wharfs.

It's not worth taking the SLR rig and I think the compact setup is better for the difficult conditions. Currents and terrible vis are the norm.



I have been using the Inon S2000 strobe with fibre optic sync cord but that presents some problems. Because the strobe always copies the camera strobe it always gives 2 flashes. That means you cant use full or half power because the strobe can't recharge in time for the second flash.

Using the Triggerfish slave sensor with a wire sync cord and Inon Z220 means I can use the full range of flash power and have total control. The triggerfish can be programmed to fire on the first or second flash. The Inon's dials are much easier to read and operate too.

I also added a focus torch mount using Locline which matches the one on my SLR housing.

3 inch strobe arms

It has recently dawned on me that my strobe arms are way longer than needed, and I have always thought the Ikelite handle posts were too high. It has always been more of a problem getting the strobes in close enough to light close subjects rather than out wide enough.

So with the help of Mr Leung from ebay here is the new strobe arm setup (lower image). Strobe positioning, shooting in tight spaces, carrying, fitting in the wash tub and storage cupboard are all now much easier.

Handle posts are 30mm and anodised red (previously 90mm), arm sections are 3" (previously 8") Apologies for the mixed measurement units.

Here's a shot from the first test dive showing that even with a 10mm fisheye and heaps of muck in the water the strobes could be positioned effectively.

Macro lens mount in use

Next week has arrived and the weather is calm and the water is chilly and clear.

Here's a video of the lens holder being used on a St Leonards Pier photo dive.

Merimbula Divers Lodge - Eden Tugs

After Jervis Bay we headed down to Merimbula (4hrs) to stay at the Diver's Lodge and dive the Eden Tugs. The Tasman Hauler and Henry Bolte tugs were sunk as artificial reefs back in the mid 1980's in 25 to 30m. The Tasman Hauler is intact while the Henry Bolte has collapsed but boasts more fish life. They're only a 5min boat ride from Eden wharf and about 150m apart.

The diver's lodge has 3 large two bedroom apartments for $29/person, 4 bunks per room. Absolute luxury as dive lodges go, and walking distance to great restaurants and the main shopping drag. We've stayed there twice and always had an apartment to ourselves. Excellent washing and gear storage facilities are provided.

Dive time was 8.30 at the Eden wharf, 20min drive, where we geared up with a Pro Dive mob from Sydney. They were also staying at the diver's lodge and doing a wreck course. The dive boat is a Niiad RIB with just enough space for 12 divers and 2 crew. It's a fast narrow boat that has no storage space for cameras, have to be very vigilant to protect cameras in the pre dive melee.

The vis was 15 to 20m allowing for great wide angle shots. A big school of 60cm kingfish provided thrills on the Henry Bolte. Much better than the 5m green snot we had last visit.

First dive was on the Tasman Hauler then back to Eden for the surface interval, then back out to the Henry Bolte.

$120 for the double dive with your own gear.

Tug dive photos here

For this trip I really wanted to concentrate on wide angle and video. I used my Nikon D80 in Ikelite with 2 Inon Z220 strobes all on manual and Sigma 15mm fisheye, and Virg's Panasonic Lumix LX3 in my old Coolpix 5000 Ikelite housing with a UK Light Cannon HID torch for video.

I took Virg's Macbook and edited video as the trip progressed. This gave me something to do during down time and show off to the non photographers each night.

Rich and I used drysuits, highly recommended, and although the water temp was 20c in JB and 18c on the Tugs, it made the between dive times warm and comfortable. Wetsuit divers shivered.

Next time I'll take my ali backplate rather than heavier SS just for easier handling out of the water, and use an occy neck sling or velcro retainer rather than the useless mouthpece plug.

Inon repair

The strobe has returned all fixed, no charge.
Yay Sea Optics, my new best friends.

Inon sync socket replacement

In a previous post I mentioned that one of my Inons needed a replacement sync socket.

The problem probably originated 4 yrs ago when I bought one of the first Ikelite to Inon sync cords. The finish on the Inon end of the cord was awful with razor sharp edges and vice crimp marks. I brought this to Ike's attention and they replaced it no questions.

However the damage had already been done. The few times I used the original cord had scratched the o-ring sealing surface of the Inon. I smoothed and polished the scratches fairly well but I guess over the years enough salt water seeped through to cause corrosion of the contact pins.

This came to a head in Tassie when I didn't undo the sync cord for maybe 36 hrs and the photo shows the result.

Anyway I sent it off to Sea Optics for a replacement. Total cost was $330 including $135 for the socket, $127 labour plus o-ring kit and pressure test. Way more than I expected but this ain't a cheap hobby! Strangely the socket was installed 180 degress rotated to where it was, meaning the brass locating pin was at the bottom.

It worked well for the 10 or so dives since but then the socket started to rotate when screwing and unscrewing the black plastic locking collar on the sync cord. Apparently the socket must have sustained a knock or I have tightened it up too much (neither of which I am aware of) wrenching the locking pin out of it's hole behind the socket.

The strobe is now holidaying again in Adelaide and I shudder to think what the bill will be.

So that's why I haven't posted many images lately.

Technical issues on the Tassie trip

Had no problems with the D80 and my lens choices were perfect. Just the 60mm macro and 15mm fisheye.
But how to store and backup 10 days worth of images. I considered buying more SD cards, an image storage device or an iPod/camera connector but found that basic laptops are so cheap these days that there was the obvious solution.
I bought an HP Compaq C710 for $750 and with the current $150 HP cashback that made it $600. It only has 512 RAM but that was fine for saving images and running Photoshop Elements 2.0. The laptop became hot property after each dive as everyone gathered round to view images.

I found Vista to be a very nice, almost Mac like OS. This PC wont be connected to the net. On return I slotted in 2GB RAM for $130 and it runs better than my iMac 20" G5 now.

Now here's a list of gear problems on the trip:
Virg's Aladin Sport wrist computer went "ERR" - meaning Trevor had to borrow one from the dive shop.
Leaking drysuit chest valve - got wet thermal tshirt and jocks every dive. Drysuit needs valve overhaul.
Leaking Inon Z220 strobe socket - now realize this has been going on for a while so the strobe is getting the socket replaced at Sea Optics for $88 plus labour
Port o-ring sucked into the housing - after opening the rear door on the boat to switch back to autofocus. Glad I saw this as it would have meant a severe flood. So didn't take the camera in for this dive at Waterfall Bay split and enjoyed it so much I called this my best dive ever.
