#381371 Custom white balance and noise

Posted by thetrickster on 09 February 2017 - 09:59 AM

White or Grey. It doesn't really matter. The key is to have something that has no colour cast (so have the same about of Red, Green and Blue)

I have a WB slate which has actually a slight blue/green cast so making the camera over compensate a little towards red.

But anything Matt white or grey is a great start

Here are the GH5 overlaid (in Red) the GH4 - as you can see the GH5 is quite a bit different in all aspects

#381168 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by thetrickster on 02 February 2017 - 10:26 AM

Oh and btw, would all/most of the buttons work on the gh5 in a gh4 nauticam housing?

The housing door won't even close if you tried the GH5 in the GH4 housing (if we are talking Nauticam) as the GH5 is thicker (and about 10% more in volume)

725 grams? That's a hefty body indeed!


Yup, especially considering they removed the flash part too and the battery is the same.


Can't wait to get it underwater!

Sorry Davide, looked through all my FCPX Projects I can't find the dive I did looking at all the ISOs and Colour Profiles. Sorry [emoji52]

I'll see if I can find my ISO tests I did (underwater) a while ago.

#380297 Are people leaving micro four thirds?

Hi Sully,

Just a quick bit of trivia. The Olympus underwater housings and ports are actually made by a company called AOI and branded Olympus.

Apart from the material the housing is made from, there is little functional differences in the housings. I suppose one of the benefits of the Olympus housings is that they are more buoyant than an Aluminium from Nauticam or others - so you potentially don't need the float arms that I seem to have a lot of..

Reasons for going for a 'generic' brand housing from Nauticam, Aquatica, Sealux and others is that the port system is transferable between different camera brands, so one year I could be shooting Olympus, the next Panasonic - so you can invest in your ports (as they are not cheap) and know they will last for many years on future cameras.

Going with Olympus they made it difficult on some of their housings (previously) to change ports and then you are limited to a very small selection and also they have been known to change the port mount completely between cameras - so you really can only buy for your current camera, with the likelihood that you will need everything again for your next camera.

Also the Aluminium housings are rated for sub 60m - even 100m+ dives and have many additional advantages like vacuums and leak detectors, better ergonomics for gloves, handles etc.

As to sizing. The m43 cameras and housings are slowly creeping in size (compare my old EPL1 and the GH4 for example!) so I would suspect with the GH5 and EM1mk2 the housing won't be much smaller than a Sony or even a mid sized Canon.

There is no way to operate a manual focus on that lens!?

What some great tips for using magic-filter + lights - would never of thought of doing that with the WB

Thanks for posting!

#378468 Deep Macro

Posted by thetrickster on 05 November 2016 - 11:39 AM

Agreed the DPV should be a pretty good tripod on its own. But depends how you have it sent up. Buoyant or Negative (reminds me to add more nose weight to mine [emoji848]) so you will have to have it a negative.

AF for macro. A small aperture and a manual AF to get you in the ball park should give you focus and enough dof.

A little tabletop tripod I've used is the Manfrotto ones. They have a ball head on top and are pretty good. Just need to wash well after diving.

Re the GH4. The Continuous AF is pretty good if in HD but sadly poor in 4K.

I had it on, on a trip to Sri Lanka. Didn't think much about it as the rear screen looked okay. It was only when I got home and reviewed the footage, every now and again it would refocus and sort of spoil the shot. Plus you can hear in the audio the focus motor always going.

So now it's off, with the switch on MF, the back button set to 'AF-ON', which following the latest firmware works while recording now and shutter AF on. (That was another mistake, having that off... a bit narked and happily recording everything out of focus for a whole dive as I had forgot to set focus....!)

#378013 Color Correcting Purple Water

Posted by thetrickster on 22 October 2016 - 12:00 AM

Dreifish. The corrections you made to the footage really make it better.

This is actually quite an interesting discussion. As it's all very subjective.

I had a play with the footage myself yesterday (also with CF Pro) and ended up with a slightly different variant. I tend to step away for a day and have another look as the longer you spend on a clip the worse it can become. Some stuff I've done is horrible, looking back!

Apart from the above you did with CF, I added another couple of CF layers and masked off the diver with shape and colour mask and made the black less saturated on the suit, while not blowing the tank highlights (while keeping everything under 100IRE) I also (tried to) neutralise the skin tones.

Perhaps we should have a show and tell of the same frame grab and see how everyone has a different view on correcting and can learn from others what they do. As looking at mine and yours. I prefer your blues!

#377993 Island of the Gods - Bali

Posted by thetrickster on 21 October 2016 - 10:55 AM

Loved it. I actually loved the intro, the aerials. Everything. So much nicer than the standard diving videos, which most of us are guilty of - straight into the underwater stuff.

Really lead you into the area you were diving.

Lovely mix of WA, divers, macro.

And again. That bloody Canon of yours really showing us how MWB should work. Deep blues and lovely balanced foregrounds.

Only thing I would say. Would be to add a bit of post stabilisation to the underwater stuff on the parts where you are going over / pass stuff. But I'll being real picky !

Again. Great stuff!

Howdy Drefish,


Alas I've been away working, so my planned trip to the Red Sea was put off, and the local beach I have here locally is utter rubbish for diving, let alone uw camera stuff.


I have had it in the pool - and I'll see if I can get in there again this weekend. But so far:

+ Major upgrade in stability, when I get the GH5 with IBIS I can see footage being silky smooth.

+ The top bar and tray, really make the rig strong.

+ Amazing detail and 'WYSWYG' on the screen

+ Lovely bright and colourful screen, compared to my Ninja2

+ Waveform and Zebras monitoring for ETTR

+ Focusing is spot on, can really see what is or isn't in focus

+ 10bit Prores 4k is a world apart from h264, I will never shoot in h264 again!


- Not ideal screen position - very close to you, but perhaps I just need to get used to that, but at the moment I'm holding it out in front more.

- Heavy

- As I'm recording in 10bit, I can't have the GH4's info displayed externally, so changing settings, I need to 'flip' the flame up to see the screen for changes for example to WB, ISO etc.
