Actually the whole thread is worth reading but that post is amazing.

Seeing your footage it seems you were there nine months not nine days :)

As I told you my two year's son cannot sleep without seing one episode.
When do you come back there?


#351846 In the shadow of the volcano

A wonderful weekend between the Gulf of Naples and Sorrento with the sight of the Mount Vesuvius above us.


Filmed on three dives:
- Scoglio del Vervece, Massa Lubrense, Naples;
- Isca and Palluscello di Isca, Nerano, Naples.


Unfortunately underwater viz was bad with a annoying current  and particles. I couldn't avoid a lot of backscatter but, who cares! I had a great time diving, filming and.. editing.

Shot on a Panasonic GH2 + Lumix 7-14mm loaded with Nick Driftwood's MOON T7 settings; Nauticam Housing, 2x Keldan Luna 8 CRI lights on camera and 2x FIX Aquavolt3500 lights on model.

I did indeed, and I have 7 lenses for it already. 


7 lenses? Big trigger indeed  :dancing:


Looking forward reading your opinions and some material of course :)


I think I will die with my GH2 like that ones who died with they wonderful PD170 with the HD arrival

Nice. What does "by wire" mean?


It means that there is not a direct mechanical connection between the focus control and whatever lens elements move to focus the image on the sensor. Instead the control tells the camera's internal controller and motors to move the lens elements.


Nick did you pull the trigger on this camera yet?

#349741 GH4 footage and rig pic

The issue of autofocus with the 4:3 cameras is that is is slow and sloppy however considering that the 7-14 has a minimum aperture of f/4 and the camera a 2x crop factor you can focus the camera on land at 3 feet, lock focus, jump in the water and you should have all in focus from 1.5 feet to infinity.


If instead you are shooting something closer or you zoom you have a problem and you need the camera to focus this is where manual focus is useful as autofocus as mentioned before is .....not that good


I do not agree here,


With my beloved old GH2 autofocus is fast as hell with 7-14mm. I tested hundred of times in really challenging conditions. IGH3 autofocus si still better than GH2. 

On video you have to set spot focus, not multi point.

It's the same old problem of forum search that skip search keys with three or less letters.
We should suggest to panasonic to name the next camera with a longer name ☺

#346887 Upcoming Panasonic GH-4K

Posted by Davide DB on 28 April 2014 - 12:07 AM


 I was going to ask that if, despite your disclaimer, you were going to make the switch  ;)

Mine, ahem, is due to ship next week :)


Little bit OT...

The problem is that it's very difficult to sell. Yes I will not produce any better art with it. It's just my try to save some money for the future  :mocking:

Furthermore I will keep for myself optics and ports that are compatible for the upgrade so it's difficult to sell just the housing without a port. I managed to get a 14-42mm port.

Good news for my 22 months old baby!

He is addicted to reef life of Andamans and Muchy Secrets, prologue. So finally a new hit!


Good work

IMHO Matt Scott tutorials are some of the best out there as clarity and authority. 


He is a Edius guru and nearly all I learnt about Edius CC comes from his tutorials. They worth a look because most of that concepts are valid also for other NLE.

BTW There are some comparative tables against an upcoming 7D MKII :)

#342940 Hero3 Black. How do I take advantage of this high definition camera?

Posted by Davide DB on 06 February 2014 - 02:06 AM

Have fun Davide...



Hi SPP, glad you liked my test but.. you are ovverating me :)


At the beginning I installed GoPro Studio to run some test with protune and cineform files. I loaded both on the timeline. My project was using Canopus HQX codec (4:2:2 10 bit as Cineform) which Edius transcode in background while editing. I tried to CC both and I found no differences between them. Cineform files where huge and lighter to edit but once the HQX files were ready  no difference at all.

I'm a beginner so maybe I missed something. If I can I try to edit and CC in the same editor.

I found that the best filter/tool for underwater clips is the crominance mask: it let you pick up easily one range of color (e.g. all the water) without touching other part. After that you can apply whatever filter you like to this selection. A simple three wheel color correction to remove that water green cast.

When later I saw the result on my TV I realized I forgot to apply an Unsharp mask. But I was too lazy to reopen the project  :sleep:  Anyway you are correct: current edit is way too soft.

I have a  DELL U2412M monitor and I'm realizing there is a lot of difference between what I see on my monitor and other TV/computers. It's becoming a problem...
