#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.




#377576 Am I crazy for spending this much money for being so new to this

Posted by thetrickster on 04 October 2016 - 02:34 AM

I agree.

 

I bought two z240's and ended up selling one and just concentrating on one - much happier with the results.




#377314 Panasonic LUMIX GH5 for underwater video

Posted by thetrickster on 22 September 2016 - 05:58 PM

Yes. You're right. 4:2:2 10bit will not be for 4k@60.

And yes the card format will be SDXC UHS-II.

It was on one of the Facebook GH4 groups I think I saw this info / photos

#377307 Winter musings

Posted by thetrickster on 22 September 2016 - 12:43 PM

Hi Swift,

You are at a very good (and bad) time for upgrading. First reaction - Wait for the new camera reviews in 2017 and the AX100 replacement and decide then.

An external recorder for your current camera I don't see giving you any extra image quality it will still be 8bit and 4:2:0 - although uncompressed - its still has a lot of data stripped from the sensor. So unless you fancy a super nice viewfinder - It wont be worth it.

The 'first' generation of consumer 4K cameras with 4K@30p are now 2yrs old (GH4 and AX100 as an example) and the current mid tier models (GX8, A6300) are not really setting the world on fire with hardly any improvements (well apart from the A6300 when it overheats!)
So obtaining one of these first 4K cameras, you could get a bit of a bargain and still have a great improvement in image quality - IF you can get one for a bargain.

The Sony A7 Mk II's are interesting - with their amazing low light and also fast phase detection AF. Alas the limited lens choices for me don't sit well. Plus they are not cheap and you know Sony will have the Mk III's out for Christmas!

Its odd at the moment, that we are caught with DSLR type cameras having massively better image quality than camcorders (DVX200 not much better than the GH4 (and no housing), the Canon's/JVC suck at 1080 etc - and that was (at the time) the reason I went down the GHx road (there was no AX100 at the time, when I got my GH3 and housing) and the semi-pro Sonys of the FS5 and FS7 are serious money once you get the firmware upgrades and Sealux housings...

The BlackMagic camera really want a controlled, well lit environment to shine - and when I looked at the BMPCC, it was awful to use in a housing, the amount of hours in front of a PC to convert the RAW stuff - just didn't seem worth it add the fact its a S16 sized sensor so needs super wide lenses to get even a 'normal' wide shot. Everything says no to me.

The AX100 would be a serious contender for me, if I had nothing and needing something 'today'. Pete in Oz has worked out that the Magenta filter fixes a lot of the WB issues and it benefits from all the camcorder features (parfocal lens, OIS, continuous AF that doesn't hunt, ND filters and then you have the video centric options on the housings like the flipable internal filters and excellent buoyancy characteristics) - so a really good choice. It is sadly let down by the awful rolling shutter thou - but others can comment if this has any effect underwater.

If I had nothing and could wait, we have info on the 'new' models coming in 2017 and they are coming with 4k@60p and this along with HDR will be big - very big, as you know the camera aspect of an underwater camera 'rig' is just chump change once you buy housings, trays, lights arms etc - and investing in a 2yr $1000 camera (plus the $3000+ on housing) now doesn't make sense, now we know what is coming.

Need today: AX100 or a knocked down GH4.
Wait for 2017: GH5 or AX100 MkII (whatever they call it)

Im happy with my GH4 and Atomos Flame - its missing a lot of video features - but I've learned to work around them (rubbish AF, no AutoISO in Manual mode etc) - but the image quality I'm super happy with and if the rumours of IBIS are in the GH5 and if they improve the AF, i'll be happy to stay with the GHx series worts and all. (But always with a casting eye on the Reds and FS7 :)


#377220 Panasonic LUMIX GH5 for underwater video

Posted by thetrickster on 20 September 2016 - 12:08 AM

Looks promising. But I don't think I'll be pre-ordering - just yet. There are still a few unknowns which I had hoped would be mentioned yesterday.

 

Apart from your list:

  • V-LOG (rumours from the floor - it will be paid upgrade again)
  • Crop Factor in 4K modes (no mention)
  • It will require the newer UHS-II Type cards (looks like they tried to cover that sticker up and failed.)
  • No word on compression
  • Dynamic range / Better low light

Lovely video!




#373681 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by thetrickster on 17 May 2016 - 12:51 AM

 

So I guess you need to buy the zoom gear and substitute one of the three pieces for the printed one. Am I right?

 

Yep, that about it.

 

The zoom gear has springs and is actually quite complicated - not something personally I could design and print. So I needed the zoom gear and modified it.

 

Jussi at deep shots might have a more skilled hand than I - and maybe a better printer to do a more complete custom piece.




#373041 Color Managed Video player..... OMG!!!!!!

Posted by thetrickster on 26 April 2016 - 11:22 PM

I agree that the Scenery profile is much more suited for the Panasonic's underwater. I'm too much happier with it now I'm running that profile.

 

(Which was your suggestion a few months back)




#373040 PADI Photographer White Balance Slate - Gray Scale

Posted by thetrickster on 26 April 2016 - 10:50 PM

'Grey' for White balancing isn't a specific 'grey', can by 18%, can be anything really - the main issue for using a grey card for white balancing is that the card is completely Neutral, so the R,G,B values read off of it are the same - The PADI card is indeed pretty neutral - and its a Matte finish too, which helps.

 

The only issue I would say with the PADI card, is thats its quite dark (for grey) - so some cameras might not like it and refuse to WB off, of it.

 

Don't forget its a $15 card also - they will not be checking the consistency of the neutrality of their cards, unlike XRite or DSCLabs - but for us underwater I think its pretty close.
