  1. This weekend, I got a late call up for a dive on Sunday morning and in a rush I grabbed my GH4 and the 14-42mm. I have been planning to get the GH4 down and do some testing with it - actually underwater, but I wasn't quite prepared!! I've had a go with all the profiles on land, but have a feeling, the differences don't translate to underwater filming. I was taught that you should shoot as flat as possible and then grade in post, however this is all (in my opinion) absolutely rubbish when dealing with underwater footage, unless you are shooting RAW with a BM camera or similar. We are limited to 8bits and only 4:2:0 - so my current thought is to bake in as much as I can while shooting.. Anyway... So got down to 25m and the vis was rubbish, but I proceeded to setup my GH4, white balanced off a slate, pointed at the wreck and starting running through all the profiles, recording 10secs a piece - thinking Vivid would be a good one to start with, as its quite contrasty. I was surprised however that the Portrait profile provided some nicer colors, but again is a bit too flat for my liking. I didn't have time to run through all the profiles and all the iterations (buddy was looking very bored) of shadow/highlight adjustments, contrast, sharpness etc. So wondered, if anyone else been through the different profiles and found a gem to use?
  2. Raja Ampat had so much opportunities from an underwater photographers perspective, here are some of my favourites. Equipent used: GH4, Nauticam housing, 2x INON S2000 8mm FE in 4.33" dome and 3.5" dome 60mm and 25mm in 60mm macro port Many more photos can be found at: www.flickr.com/xanderwater Cheers!

  3. GH4, Nauticam housing, Panasonic 8mm FE and 3.5" Nauticam mini dome, Western Australia.
  4. Here is an example of a GH4 video that I've just finished editing: http://www.peterwalker.com/komodo.html It demonstrates the camera's capabilities both WA (7-14mm lens with Zen 170mm dome), Macro (14-45mm PZ plus flip Subsee +5 dioptre) and above water (12-35mm plus polarising filter). I did all the editing in 4K and then compressed to 1080P just before uploading to Vimeo. It was a pleasure to shoot and edit! Regards Peter Thanks to David Cheung of ScubaCam for helping put the equipment together for me.
  5. Photos taken on snorkel in Western Australia all in max 2 meters of water in the Swan river/estuary here. GH4 in Nauticam housing, with the 8mm FE in Nauticam 3.5" dome and the Olympus macro 60mm in Nauticam macro port 65. I heard the 8mm in 3.5" mini dome would vignet slightly, but it does not. One handle removed from housing and Single INON S2000. Some minor PS tweaks/sharpening, slight crop on a few of the photos. Nauticam housing is very good to use, both lenses are great as well. I am finding quite some pink/green artefacts in my photos, also in low ISO, especially in smooth gradients of backgrounds. Not sure if the GH4 has difficulty with that or if I might have to tweak some of my settings. This was something I did not notice that much in my old RX100 photos. For the rest the GH4 in Nauticam is awesome to use. Macro: I think the RX100 might often be sharper when you see 100% detail, but a lot less versatile than GH4 with dedicated macro lens.
  6. I am moving in a different direction now & the GH4 no longer suits my needs. This has only been dived about 20 times & is in as new condition. You will need a lens/port combo of your choice. Located in Sydney Australia. $4000 Aus plus postage. I also have a set of used Sola 4000 video lights that I will sell for $2000 aus with this setup if anyone is interested.
  7. https://vimeo.com/103312019 4K on youtube: http://youtu.be/8tc8XEAUiHc A very short video of Pygmy Seahorse (Hippocampus bargibanti) from Anilao, Batangas, Philippines. Shot with a Panasonic GH4, Panasonic 7-14mm and Olympus 60mm lens in Nauticam housing, Aquako 4K lights and diopters. I was using Standard profile (-4,-3), crushed black a bit in post. Oly 60mm produce very sharp image but I'm not happy with working distance (too short) and "by wire" manual focus. P.S Try spot the seahorse on a seafan (WA shot).
  8. Hi Guys, Here is my latest work, a mini documentary on the Tubbataha Reefs in the Philippines. Warning: If you haven't been there, this video may cause you to instantly whip out your credit card and book a trip for next season. Tubbataha reminded my of Sipadan back in the good ol' days. Maybe even better. Fantastic diversity, huge schools, sharks and turtles everywhere, pristine corals and, on some days, visibility up to 100 meters! It's remoteness and short season helps but the Philippine government is doing a good job policing the park's "zero take" policies. Enjoy: http://www.peterwalker.com/tubbataha.html Regards Peter
  9. Hi all, Here's a 2 and a half minute video from the Panasonic GH4 in Cat Island last week: I also wanted to show this shoulder/stability rig that Ryan made up for me as I was leaving for the airport. It made the whole thing a bit larger and more awkward on land, but underwater it was terrific. I would typically move the monitor higher when I shot, but it was nice to be able to move around as needed for the sun angle. Cp
  10. If you use Sony Vegas Pro, I established a workflow that overcomes Vegas' import bug for various GH formats, and allows C4K etc. footage to be edited via proxies, even on an ancient computer like mine.
