  1. I have no upload allowance on this post! Light room looks marginally worse than the corrected DxO has a bit more crop to it and the corners are worse The pull however is not the correction only is also perspective distortion that can’t be avoided and the primary reason why I no longer have a 7-14 mm lens. At 7mm is much worse I found I had it on my blog https://interceptor121.files.wordpress.com/2019/10/perspective409mm-f-8-20191012.jpg?w=1024 Sent from my iPhone using Tapatalk
  2. I posted already somewhere else here https://www.iata.org/whatwedo/cargo/dgr/Documents/lithium-battery-shipping-guidelines.pdf For non cargo you need to follow the rules for batteries packed with or in equipment you can’t carry batteries without equipment that only applies to cargos LiIon is forbidden in any airlines on regular non cargo shipments Sent from my iPhone using Tapatalk
  3. If you dont carry the camera or light technically you cant carry any spares on their own and clearly no packing in checked luggage of any li ion in any way Sent from my iPhone using Tapatalk
  4. The limit for batteries contained in equipment and packed with equipment is 5 kg per passenger with maximum two spares in addition to what is in the equipment So if you have a video light with a battery you can take two spares no more If you have a camera with a battery inside you can also only take two spares The total of your batteries in and out equipment is 5 Kg AA batteries for strobes and NiMh do not count and can go in check in In theory for your gopro you can only take two spares each and two inside so total 2x3=6 and 6 video lights In practical terms I have never seen this stuff put on a scale or a count of batteries but those are the rules
  5. Actually in stills the frame at 7mm is 85 degrees more than the wwl-1 and difficult to cover with strobes 8mm instead is great 95 width and 78 height the strobes cover it perfectly and perspective distortion is limited The wwl-1 narrower than 7mm is easier to cover with lights or strobes Sent from my iPhone using Tapatalk
  6. Example against a rectilinear object 100% correction 0% correction As you can see without correction the barrel distortion is visible
  7. As I wrote on the diagonal is 130 but horizontally has the same fov of the 7-14 All diagonal fisheye are like that so this is normal but majorities of people dont know For me what matters most is the horizontal axis This article I wrote has the table https://interceptor121.com/2019/05/12/nauticam-wwl-1the-best-wide-angle-lens-for-underwater-video-on-the-gh5-and-other-micro-four-thirds/ The 7-14 rectilinear lens has the same horizontal field of view and is actually wider vertically this is because fisheye like lenses compress the frame with barrel distortion. Now 7-14mm is not a useful focal length for me because perspective distortion is so accentuated that the shots look weird also on land more at close range in water Sent from my iPhone using Tapatalk
  8. Blue green whatever basically not good conditions to shoot without strobes and too deep... Which is the reason why haven’t bothered yet Sent from my iPhone using Tapatalk
  9. She is using raw images so this appears a mix of white balance and dehaze I guess the different shots get the appropriate level of correction you need So this could work when you are at depth where colors are still there but not replace flash anyway Blue scatters light and dehaze removes scatter but water also absorbs light both in terms of color and general intensity Looks very promising for ambient light shots at shallow depth for those that are not that good at post processing Still many shallow pictures once gone through current tool look pretty good and not as different as those results Sent from my iPhone using Tapatalk
  10. The results of the technique do not look that incredible to me? Most of the close shots once white balanced properly they look pretty much like those in the video. Maybe I am missing something but I do not see lightyears between the examples and pictures I already take today once corrected
  11. Rectilinear lens 20 mm and longer in 35 equivalent to avoid the kids look weird Of course you can shoot a fisheye but it looks ugly
  12. The manual focus only works with wet lens that shortens the focal length Without it you will just have blur The GH6 if it comes out next year wont be a game changer Panasonic has committed to 8K by 2022 and the Lumix G already got a significant firmware update suggesting new products are not coming too soon Sent from my iPhone using Tapatalk
  13. If I had to get a single rig for the best still images it will have to be the Nikon D850 While in terms of pure image quality there are other options on the mirrorless full frame camp and the choice of lenses and ports is catching up too on the ergonomics and shooting performance a traditional DSLr is still much stronger and considering how complex is to take pictures underwater this is a deciding factor Sent from my iPhone using Tapatalk
  14. I posted this specific point in the video section because I didn’t want it to become a generic discussion on white balance yes or no for RAW images The video workflow is totally different from stills and even if you white balance you still perform adjustment in the final stage of your edit so clearly having footage that can withstand color manipulation helps however raw video is not mainstream and even if you can get to 50000 K in post if you were too off during capture it looks weird exactly as it does with still images and this is one of the reasons I am advocating the use of filters in ambient light shots and white balance in capture So am aligned with what Adam says in terms of not being too far off whilst in terms of correcting in post it is not an issue because you typically have homogeneous clips that are short in duration and this is just the way it works in video Sent from my iPhone using Tapatalk
