4K Sony RX100 IV Underwater Green Island Taiwan

[leo999 11]

this video was shot at 4K resolution, by sony rx100 IV with Marco diopter Subsee+10, and 10,000 lumen lights X2, and did some post production color correction and so on.

Location: Green Island , Taiwan

Leo, some nice macro in LuDao. I have a question:
A few of the wide angle shots had a lot of magenta cast, at least on my screens. What kind of post did you do and with which program? What was the original like?

 

[leo999 11]

u are really good of ur eys sharp, yes, some of those shot i corrected not perfectly, i am lazy to shot in custom WB underwater, i will do color correction after i back home on software.

i use premiere pro CC 2015 to work with it

although, it's not for sale, just for personal creativity

i capture the original pic for you

thanks for ur comment

Nice video. So is custom WB underwater difficult to do? Are you using a Nauticam housing?

[bubffm 178]

very nice, Leo. Did you use a red filter?

nick, i really do love ur video, your videos are something really i learn from, still got many things to learn..

i use SEA&SEA Mark 3 housing to fit in my Mark4 camera, the problem is not my housing, is myself , i am lazy to bring a white board to correct WB underwater,

i feel, it's not correct WB anyway underwater, why not do it at home? and WB changes by surroundings, by depth, why not focus my attention on composition or anything else, shot first, correct it at home?

do u still suggest me to set manual WB every shot?

 

bubffm, i have a red filter on big wide shot

The RX100 in the standard mode pushes blue towards deep blue and magenta to deeper magenta

So when you shoot with a filter in auto you need to dial down the blue and add yellow and green

I have had the same issues before working out the right settings

However the new RX100 has also picture profiles and the profiles PP3/PP5/PP6 or PP7 slog2 will not have this problem

Profile PP1/2/4 and off will have the over-saturated blue and magenta and weak yellow

leo99 - I try to do manual WB underwater to get close, so that less correction is needed afterwards. There is still some, but I'm not running running out of room to make those corrections.

 

I don't use a white card either - I just dive with white fins when I'm filming, and sometimes using light colored sand works even better than the white fins. Just some thoughts.

Thanks. Glad you like the videos.

 

To a certain extent underwater white balance is a matter of taste, so there is no definitive right or wrong. I like near things to look pretty much like they would if they were lifted to the surface. Others prefer a more cyan look. I can't watch your video on my current connection but judging by the stills I see above, your WB is way off what I personally like it to be. It looks so skewed towards blue-purple that you will have problems trying to "correct" it in post. You're not shooting RAW or 10-bit 4:4:4. There's only so much you can do.

 

You don't need to WB every shot, but I like to white balance with every few metres change of depth. You don't necessarily need a white board. You can white balance on the palm of your hand, or on white fins, or on white duct tape on your fins etc.. None of these will be exactly right, but they'll be much closer to a pleasant white balance than what you're doing now. Experiment and test. This very old post (see post #147) on some white balance testing I did with my Sony Z1P may give you some insight and ideas, but bear in mind that those old Sony 3CCD video cameras were more predictable in manual WB than many of the more recent Sony cameras.

nick, thanks for ur advice

i have spend times to read those thread u share, are u guys still using the expodisc ? even ur gh4? i have find some other latest product , like: http://www.bhphotovideo.com/c/product/591756-REG/BRNO_BAL77_baLens_77mm_White_Balance.html

what kind of tools are u using right now for WB?

By sending you to that post I didn't mean to recommend using an Expodisc, and from my point of view it was a bit of a red herring. From what I recall, only Dan Deck was enthusiastic about using it. From my tests in that link I preferred white balancing on the palm of my hand, so that's what I continued to do with my Sony Z1 and the Expodisc went in a drawer. I would forget about using an Expodisc or similar product underwater.

 

Now that I'm shooting with the Panasonic GH4, I've continued to use the palm of my hand when I shoot wide angle, partly out of habit. The results haven't been as pleasant as with the Z1, but it gets me close enough that I can adjust in post-production. I haven't really had time to do some proper comparison testing. I've done some shooting with a Magic Filter (blue-water) behind my 7-14mm or 8mm fisheye lens, and when the filter is on I think I get a better result by pointing at sand than at my palm. You could perhaps experiment with different coloured plastic sheet or laminated card. I think pale brown might be best for the GH4. I plan to do some proper testing but it won't be until February.

 

When I'm shooting macro with lights I set my white balance as a colour temperature with adjustment factor.

nick, thanks for sharing ur precious experiences , it could be very useful, i will try, thanks

Sony Cameras tend to fail custom white balance in water and tend to work better with filters this has been the case with all previous versions of the rx100 and I am not sure if there has been any improvement also the custom wb button is not available in video mode

On my last trip to Egypt I did one dive filming without using the redfilter on my RX100iv - and the results were pretty awful. Pretty much unusable even after post correction. So I don't think anything has been fixed on the mark IV on this respect.

 

However, using a URPRO redfilter and AWB the clips look very good. Therefore I'd recommend to always use a filter when filming with the RX100iv

I have tested all possible filters with the RX100 see post on my blog. The best colours are magic filter the URPRO gives some yellow cast. I use a mangrove/deeproof filter that has a magenta cast. Either way the key is to use auto white balance and correct the tint. Manual white balance is off even with the filter

[bubffm 178]

ok, I didnt really notice any yellow cast but I'll give the Magic a try the next time. As this is a foil system, where would you place that? In front of the lense of the RX100 or into the housing itself?

I have a disc cut bespoke that I slot in the Ikelite rubber mount for the URPRO
