In Topic: Umbilical video lights - where / how to mount battery canister?

29 August 2015 - 08:26 PM

Personally I would mount the battery under your rig and add some buoyancy to the top.


Here are some pictures of a system I've developed which I hope are self-explanatory. It involves attaching a small buoyancy chamber (ie bucket) to the top of the rig in such a way that it can be moved forward, sideways, or to the rear to provide buoyancy exactly where required.  Adding/releasing air from the bucket and adjusting its position allows you to have your unit neutrally buoyant and sitting straight and level, or alternatively at any angle you want, at any depth. Releasing all the air allows you to place your unit on the bottom, nice and steady for those closeup nudi shots.


It looks ugly, but it's cheap and it works!

In Topic: GH4 Ikelite housing and external monitor?

20 May 2015 - 03:48 AM

I've hooked up a Sony CLM-V55 monitor to an Ikelite GH4 housing as a DIY project.

The controls that are used regularly during the dive, like start-stop, auto-focus-lock, aperture, shutter speed, WB are all accessible without taking the right hand off the handle. Checking focus, exposure and color qualities now are done visually on the huge Shogun monitor.

The controls on the rear of the NA GH4 housing, like menu and the four-way dial, can be reached with the Shogun housing in the "line astern" position as there is plenty of space between the back of the GH4 housing and the front of the Shogun housing. I can easily put my gloved fingers between the two housings.

However, if you need to see the GH4 monitor, you have two choices. You can peer over the top of the Shogun housing and see the GH4 monitor from above. This should be OK for confirming the settings that you are changing, like ISO or WB. Or you can quickly flip the Shogun housing up to look directly at the GH4 screen. You might need to do this if you are going into the GH4 menus (which I never do underwater)

In practice, I don't expect to ever need to flip the Shogun housing up while underwater. I don't change ISO often - nearly always on 200. I might change WB a few times during a dive but I have my usual WB settings preset into the 4 slots so it's easy to pull the WB lever with the right index finger and press the right-most 4-way button to step through the WB presets. You can see if you have reached the best WB preset by looking at the colors on the Shogun monitor.

I also use the 3 custom settings to move between 3 preset parameters - a good way to go back to a known starting position if you've changed controls. For example, if I've been shooting in open greenish water and made some adjustments to a few settings and then I pop into a small cave lit only by my video lights, twisting the mode dial on the top of the housing, one click forward then one click back, I'm immediately back at ISO 200 and WB Auto and SS 1/50s, etc.

So, I'm quite confident that I can easily and quickly change what I need to change but let's see how it works out in practice...


Thanks Peter (and Edmond).  Looks like they have all bases covered, I guess they need to with what a setup like this must cost.  It's certainly impressive.

How do you go about operating the camera controls on the rear of the GH4 housing Peter (iso, WB up etc)?  Do you have to raise the Shogun housing to access them, or are those functions transferred to the Shogun?

In Topic: Thumbnails and bit rates

What is the purpose of the thumbnails? I don't use VLC that often, only use KMplayer to play back. I know VLC is very powerful and can stream, but that come with price of complexity so I didn't invest my time in learning how to use the advance feature.


When I'm selecting various clips to bring into my editing program I find it a lot easier to do so using thumbnails rather than file names.  A file name alone gives me no indication of what's on the cip, whereas a thumbnail often does.
