You are doing Gods work. this information is unheard of on this platform. A humongous THANK YOU all the way from Rio de Janeiro Brazil.
thank you! Great Motivation for the next Episode!!! :) Happy to read!
You're truly the best!! Thanks Venessa, learned a ton in 19 min after trashing many hours on other videos. Thanks to you, I'll finally start having decent shots on my next dive! :)
I'm amazed at the quality of the information you gave : straight to the point and perfectly clear. Thanks a lot for saving me from more trial and error !👏😃
Outstanding video. I was looking for a few pieces of info that I couldn’t find elsewhere and you covered them in detail. Thanks so much. Great channel.
Awesome information, one of the best I've seen to put all the pieces together. Thanks!
Thank you so much Vanessa!! We learn a lot with you, please keep it going and making more videos. Great job i´m so happy to discover this channel...
thank you!!! Means a lot! And helps keeping the motivation going! :)
"Ah, I'll just edit it in post" is now in the bin. Thank heavens for you guys!
simply great! Your informations are soo helpful for soo many underwater videographers, especially for beginners who are dissapointed about their footage...
thank you!!!
This is by far the best channel for underwater photography/videography, fantastic stuff!
thank you :) feel free to share!
Thanks for the great info! I ordered a Keldan filter for my 16-35 wide-angle but after owning my Canon 8-15 fisheye for the past 10 years, I've literally never noticed the insert for the filter sheets! 🤯 Ordered and ready for Socorro. Danke nochmals!
One more excellent tutorial on a very important matter! Thank you so much
welcome :)
Really helpful. I really appreciate your clear explanations.
Mega Video, wie immer DANKE für die wertvollen Infos!! Weiter so und bitte noch mehr Videos!!!
hehe... danke
thanks so much for this awesome video and hope to dive with you one day to know more and more from you❤❤❤ thanks from egypt
Your videos are the best! Thanks a lot
This is so well explained thank you very much
Love your videos! Very informative and entertaining! Wondering if you actually bring your WB sheets with you on dives? seem a bit big and bulky.
Very informative. Thank you! 🙂
amazing explanation!
Vanessa...first of all...thank you for ALL of you videos...they are very helpful. Secondly, I am using an Olympus TG-6 with an Olympus housing. It has a 52mm lens attachment and I have a 52mm Backscatter wide angle dome lens. It is a wet lens. For the red filter, I attach the red filter to the housing and then the lens to the filter. It is essentially doing the same thing as using a filter sheet. Just another work around I thought I would share. Again, thank you for all your hard work giving us beginners all these fantastic tips!
Top, wie immer. Sehr informativ!
Danke sehr :)
merci :)
Sometimes i just watch your videos to look at the way you speak ,it's very relaxing ❤️
I've been binging your videos trying to learn the ropes of this stuff. Thanks for all the great content! Quick question... You mentioned the "mixed light" problem when manually white balancing and using lights. If using a GoPro and setting the wb to 6500 for example (same kelvin rating as my lights), will I still have that problem? If I'm understanding the video correctly, I think the answer to that question is yes?
The filter sheet advise was the best! I have the Tamron 15-30 mm f2.8. It dosen't have a filter thread.
THANK YOU FOR THE VIDEO IT WAS REALLY HELPFULL
Another great video!
Thanks!!! :)
Fantastic content, subbed. Quick question. Would you recommend combining a red filter and video lights for a GoPro at all since these cameras don’t allow for manual white balance correction underwater? Perhaps it’d be best to only use video lights?
Great videos... a little confused here. Are you recommending using the spectrum filter with the ambient filter on the Keldan? I use an A7R3 so if I attach a spectrum filter it will be there for the whole dive, regardless whether I am shooting at shallow or deep depth. Thank you so much.
Thank you once again BTM! I have a question. Normally I would wait for the most excellent Q&A episode but I have an upcoming trip with a new rig. These are vacation dives in Cozumel. First dive 100 max, then plenty of time at 60. Second dive, 40 to 60. Love your support for the Keldan. Optics is where it is at. It seems my choice would be the -4 stop spectrum. My lens will be a lumix 12-35 . I believe it has a fixed aperture at 2.6. Does this seem like a good fit? Also do you know at what depth I will lose the redness from the filter? I would be good if say by 8 meters the filter “ normalized”. I used to have a flip, but now with a dome I am locked in. Thank you so much. Your venture is tremendous and I look forward to supporting it. How about online work shops where you give us fledglings projects and you grade an critique. Or something as such. Thank you
Huge thanks for these valuables infos 🙏👌🏼 I wonder if you can do a WB correction with your own camera (internal filter) instead of external filter?? And I wonder if you can take pictures with this setup with the same great result??? Thanks a lot, Hug 👍🏻📷🦈
Hi. the comparison between with red filter and without red filter at 1.55". Does the one without red filter did manual white balance? thank you for sharing
Perfect useful tips and guidance, you are the best on UA-cam concerning the underwater videography , really thank you 👏👏👏👌👌👌
Merci!!! Means so much
thanks! Feel free to share :)
Thank you !!! great tuto !!
welcome :)
I'm Just getting started in UW Photography and only have the money to buy an action cam. but I have added a couple of filters and lights. Thanks for the explanation on how to use them in conjunction with each other So far its been a difficult to get good results as I can't manual white ballance and don't have editing software. I am taking a trip soon so I'll try out your tips.
Great video!
ขอบคุณมากๆเลยครับ 👏
Cheers guys! The place to go 💙💙💙
Thanks. always informative. If using ambient filters on your lights, and a red filter on your lens, why would you do your manual WB before turning your lights on? Seems like it would be better to have the lights on when doing the WB.
great video, best channel for underwater photo/video!
Thank you!!!
thanks!
"use in water only!" 😂 super outtakes 👍🏻
true story... *lol*
I wrecked my expensive gels tring to attach to my GH5 lenses. The cutting to square first is a good tip
Hey, one question: Can you film in slog2 or slog 3 underwater or is it a problem in terms of color and white balance? Do color tables improve the quality underwater such as over water?
Most useful, watchable, weirdly entertaining how-to's on the interwebs. Grateful! Question: I'm using iPhone and GoPro, so limited ability to white balance. In order to avoid mixed light, use a blue filter on the light. BUT, doesn't this mean there's no red data for post production? I'd love help with this and thanks again for your amazing work.
Wieder ein tolles Video :) weiter so!
Danke Jan! :)
Danke!
great information. what about if we use the Autowhite Balance and add red on it? you thin we go close to a red filter?
Hello, thank you for your advices. Can you tell me if it is better to set whit balance manually to bring back red OR to put a red filter on the camera ? Thank you
Love your content, am learning from it, will be happy to give you any kind of help when ever you will come to visit sharm el sheikh red sea Egypt
Thank you for the tips, today I learned a new lesson. You have nice blue eyes, I need red filter glasses when I look at you 🤐
Great tips! Where do you get the filter adapter for the GoPro?
Hi, I love your. Sry helpful videos, thanks. Can I ask about whether you recommend also using red filters for still photography using strobes, or does the strobe bring in enough light? Thanks
If you have ambient light filters or the right kelvin value for your strobes. But for stills you can then leave the red filter out, because you have the whole raw data to correct. It is not like compressed video
Sehr gutes Video! Was mir allerdings noch nicht ganz klar ist: macht man den manuellen Weißabgleich während die Ambientfilter auf den Lampen montiert sind? Oder macht man den Weißabgleich ohne die Ambientfilter und setzt diese dann auf?
Very good infomartion. I just want to ask, i usually take video from 60-80ft, will the red filter still work? or do I need a red filter + light?
Vanessa, do you consider that an ambient filter is required, or that you can benefit from an ambient filter, IF you are using a Go Pro, since you can’t affect the AWB after the dive starts? Thanks!! Love the channel. The best out there.
I ordered Black Molly 2600 (2 lights) for my Go Pro 9 and they were shipped out yesterday. After watching your video about the blue light, I called the Big Blue and I will exchange those lights for AL2600XWPB (they have built in blue lights). Big Blue does not offer ambient light filter for Black Molly 2600, so I need to exchange the actual lights. I think I have made the right decision about exchanging the light. Thanks a lot for your video!
Great video with very good topic 👏 is there's any blue sheets filter you can recommend for custom blue filter for the video light because the keldan filter doesn't fit on my video light and I did build already the frame for the filters but still cant decide which is the right colours blue or light blue or dark blue ?
sadly no, because these filters are really engineered to work perfectly. So I don't know any other solution for this... yet.
I use a dome port and cannot change the filter during the dive. Therefore I'm looking for the best "allrounder" and want to do the rest in post production. In my case, would you recommend a Spectrum Filter SF -2 (2-15 meters) or an SF-4 (6 to 20 meters)? I tend to the SF4 but 4 stops are quite a lot.
Great video! We notice Vanessa uses the GH5 and shows the camera and the Panasonic 7-14 mm f/4 Lumix G Vario a micro 4:3 lens in this episode. We are about to purchase the GHG with this lens for use for both wide angle stills and video. We have had some people tell us though that they wouldn’t recommend this lens for video..... and rather we should use 14-42 MKII kit lens for underwater video, so we are getting a bit baffled. Could you provide some advice on this? Also, do you know if there is anyone that makes ambient light filters for strobes? Given we cannot remove the spectrum filter on this lens underwater, we thought if we had ambient light filters for our strobes we could then swap from shooting video across to shooting wide angle stills on the same dive. Appreciate your advice. Thanks!
You are amazing thank you so so much for your videos! I fell behind watching them due to nursing school (my brain couldn't learn anything new outside of nursing haha)
I can't wait to catch up on your videos!
I noticed you wear freediving fins (you mentioned them in an older video)
Do they give you a good amount of power*? (you know since we have all this dive gear on. I keep thinking the fins will barely move us underwater) I was thinking about trying them out...
Also, if you haven't done so already, a video on what program you use and how you go about color correcting (*amateurish*) footage -would be epic!
I love the freediving fins... work superwell for me. I use Adobe PRemiere Pro to edit & color correct. But there is alwayd DaVinci Resolve (free version e.g. that is supercool - plenty of tutorials online on that). But we will do a color grading Episode in the near future!!! :)
Reef Patrol thank you so much! I actually use final cut pro with the Alex 4D channel mixer. It's super basic but it get the job done. I would love to learn more about the science behind correcting. And thanks for the advice on the fins, I'll talk to my dive shop about trying out a pair 💕
Congratulations for your very ilustrative video. One question: where can I find the geles you show, the ones that can be cut?

Nice job - good luck
Thanks, you too Michael!
Once again great video. Learning a lot here. Question. Obviously you guys are using keldan lights and you are able to have a blue filter. I use light and motion sola 2000 lights. Do you know of anyone who makes blue filters for those, or can you suggest something how to make them myself. Also what color light filters would you be using, when using magenta camera filter (green water, I dive in northeast Atlantic so have to ask :-))?
The "Green" Version of Keldanlights for Green Water: keldanlights.com/products/filters/filters-for-video-lights/ambient-filter-af-6-bg.html For the SOLA I actually have no idea, but I must say with 2000lm if you add a filter your will block too much light anyhow. You do need more powerful lights, otherwise you wont have the benifit of using lights :( so in your case you just gonna have to live with a bit too red footage, you can always take out a bit of RED in post, it will never work like with the filters, but as they are not so powerful, you should be more or less fine.
Cara - what about if we use the underwater white balance preset on the camera itself - does add on red color?
Does a red filter make a lot of difference over just doing a manual white balance in the GH5? I find mine very accurate underwater but I'm always open to make it even better.
The screw on filters, can i attach strings in it? So that when underwater if i need to change it wont get lost and its easier to swap.
I have a question if we used a red filter with white video lights without the blue filter but then tried to add in a cooler white balance in post or boost the blues. Could it be possible that there will be some blue light information to play with that can be boosted?
When using a flip filter does a normal nd flip filter work. Or will it full with water if mounting on the outside of the housing.
Hi,
Do you think it's useful to use an ambient light filter, for underwater videography with a Gopro H9 in a Hugyfot Xs housing, and two divepro 18 plus 18000 lm ?
Hey Vanessa, for the great tip... just curious in your video you mention that a red filter should be used for depth below 3 m. and the shade of red should depend on the depth, is there a depth range for the respective shade of red to use? eg. 3-15m 1 shade, 15-30m darker shade. In your white balance video, you also did mention that if you are using a white slate for custom white balance that we need to adjust the exposure, with the filter does that still apply because the red filter technically step down for you automatically? and will white balancing using a grey slate work the same way with filters?
in this channel, is there any video to compare go pro cam vs a professional cam inside the water?
So in a regular morning dive, about 60 feet, is there a mixed light setting?
hey Im wondering where I can buy the filter for the back of the fish eye lens? the cut out ones?
🐠I’m looking for the filters for the GoPro 8 waterproof housing round screw on screw off, mentioned in your video..? Any link or help would be much appreciated thank you 🙏
Hello. Could you explain the difference between using a red filter on a camera underwater or just adjusting the white balance in the camera when shooting?
Vanessa: if you aren’t filming in complete darkness, should you still set your AWB to match the K value of your lights?
Thanks a lot Vanessa! Great video!
Quick question, if you film in RAW (Blackmagic cc4k or zcam E2 (or red...))
Do you still need the red/magenta filter on the lens? (Ok for the blue filter on the lights this is normal)
it is not as import, but also here the same applies.. if your sensor doesn't capture red... it's not there.. also with RAW ;) but it will defently be better than compressed files. Anyhow, some cameras, e.g. Z Cam, Sony have issues with WB, so using a RED FILTER will defently help with the manual white balance.
I thought the red filter lowers the green and blue to balance the down to balance the colours instead of adding red to the shot because there is no red ..
Sooooo is it ok to use a red filter on my camera and video lights during day time? Or should I use either the red filter or the lights during a day dive?
I'm going to Cancun and Isla MUjeres Mexico and will be diving shallow reefs anou 15ft -30ft using gopro set up. Being new to the underwater video and photography world....How much light will I need on a bright day in the Tropics? Do I need at all? can I go cheap and get Amazon light with 500/750 lumans or should I get Kraken with 1000lumans or even more....I know at depths of 40ft and deeper having lights is a must and even then I don't knw if 2500L or 4300L is best? mainly for now as a new diver just shallow diving
So does doing a white balance with the video lights on solve the mix light problem?
Is it better to use filters or simply colour correct in post production?
I use my uw rig without red filter but normally set my white balance to same temp as video lights (5600k) but also dial in a slight magenta tint to compensate. This works great with the lights until I get super close to the subject, then I get that reddish cast. If I got the ambient light filters WITHOUT using a red filter, would they still work like white light and stop that red cast? Reason I'm so against red filters is I switch btwn photo (with strobes) and video (with lights) multiple times on every dive. Thanks in advance.
Defently no red cast with ambient filters :)
For using ambient light filter, should I do manual white balance (with grey card) with natural light or with my video light turn on?
Ps. Sorry for my broken English. 🤣
Cool ;)
cool!
Do you use a red filter at the same time as using the blue video light filters.
Use in water only... 😅😂🤣
It's so reassuring to know that Rookie mistakes are not exclusive to Rookies! ah ah ah ah
Vanessa, You've now officially stepped up to the category of UW-Filming GODESS, as far as I'm concerned!
Melt on that Mr FLORIAN FISCHER 😜😝😆😁😂
hehe, thank you :) that's what mistakes are for... to share them so others learn from them and DON'T do them (hopefully) ;)
Hello, I have a setup with red filter with Inon Dome II with UWL-100H inside. I have a red filter that attaches the waterproof housing port with M67 thread and the red filter also has M67 thread to attach the UWL-100H. But the connection is not very sturdy and wobbly, I almost lost my dome lens assembly several times. How to improve this? Does any producer has M67 to M67 other than FIX Fisheye red filter? Please kindly help me if you know.
So does doing a white balance with the lights already in solve the problem? Or am I missing something?
hi Vanessa.i would like to ask you something.what happens when you go depper than 20 metres?red filter works even if you go to 30?thanks for your time and for all your videos.have a good day
sure :) Use a denser RED FILTER , e.g. Keldan 4 Stop Sprectrum Filter. Will block 4 Stops of light, so higher ISO and stronger lights needed! Cheers Vanessa
@@ReefPatrol like you said in other replies if the red light is not there you can't make it. Below 20m there is very few to none red light left and that is only in the parts of the world with excellent visibility. The only thing you 'll make by adding the filter that deep is that very ugly red colour noise soonest you try to white balance on ambient. Stronger lights? why? The deeper you go the biggest the effect of your lights because it is darker. In the shallow you have the sun to compete with and you need powerful lights. Anyway, the effect of your lights doesn't go further than 2 meters away from the source.
How would you white balance for a indoor competition pool? My video of swimmers is coming out with a strong bluish-green.
If i set up the camera to the light source (5000k), can I leave that setting throughout the dive, example below 10m? How it will work with the red filter if I leave the setting for the camera at 5k?
is there anyway to fix the red colour when you film above 3m?
So running the -2 stop filter with the 12-35mm and the -1.5 stop filter with 8mm fisheye on the Gh5 filming 4K 24p it is almost impossible to get good exposure without pushing iso above 1600 which is about the limit of the Gh5. Is it time to invest in the gh5s to maintain appropriate aperature valies such as f8? I’m also running 2 keldan 4x with ambient filters but they are mostly useless for wide angle shots. I would also like to be able to film in 60p again to give those slow cinematic shots. I know you shoot with a Gh5 and am curious of your thoughts
Vanessa actually shoots with 2x 8X so more power there. Also around F4, becuase witht the M4/3 camera thats a fullframe equivalent of F8 and usually enough UW.
Also try to get closer to your subject, so that you use your full light power! Other than that, clearer water and shallower :) GH5 really has it's limit at 1600ISO the GH5s is a lot better in low light.
Hello ·Where can i buy the flexible magenta filters? Thanks very much
Hey Vanessa I was wondering can we use red filter in the lens and blue filter in the lights at the same time !?
Doesn't it make sense to also use the red filter together with video lights as long as the video lights have an ambient light filter on them to solve the mixed light problem?
if only use video light with ambient light filter, and the camera without Red filter, during the post production, is it any red will be capture there?
Eine Frage hätte ich noch. Habe ich irgendwelche Nachteile, wenn ich - statt einen Filter - die Rottöne in Lightroom / Premiere anpasse? Gerade bei der Fotografie sollte ich im RAW Format keine Unterschiede haben und spare mir so die Filter. Sehe ich das falsch?
Rotfilter helfen auch bei RAW Aufnahmen. Denn wenn die Farben in der Tiefe nicht da sind, kann man sie mit RAW auch nicht wieder herstellen. RAW ist definitiv viel besser als JPG, und mit einem richtigen WB kriegst du schon sehr gute Ergebnisse, aber wenn du NUR natürliches Licht benutzt ist es empfehlenswert. Wenn du Blitze oder Lampen benutzt, kannst du bei der Fotografie darauf verzichten. Grüße :)
Thanks much Vanessa. Your video is didactically excellent and very comprehensive covering all aspects of white balancing with and without filter, ambient light and video lights. I just have one remaining question relative to the "mixed-light problem": Instead of using a combination of a red filter on the camera lens and blue filters on the video lights - wouldn't it be an option to overcome the problem by performing the manual white balance with red filter on camera lens PLUS active video lights (without blue filters). It is not surprising to me that white balancing with red filter but without lights leads to a reddish video footage after switching the lights on. However this should actually be prevented when including the ambient light AND the video lights into the manual WB-procedure.
I would appreciate your opinion very much.
Warm regards!
well that is exactly the problem, you are mixing the video lights K5600 with the Ambient light... so the camera will have issues with the WB, as you are mixing both lights together. It could help to not use a red filter, if you are planning to use the lights most of the time in the mixed light condition. to prevent a little reddish tint, but it wont really make a huge difference, because you manual white balance... before turing the lights on. It is just a thing you gotta live with and everyone has been living with it for a long time before the ambient light filters came out :) but do some testing, perhaps you camera copes better with mixed light and the results are better, who knows. Best is to do some tests with and without the lights on at different depth from the same scene and then you check out your shots later on the pc. let us know!
Thanks much Vanesa for your feedback. In fact, my previous camera (Sony AX100) did cope nicely with a manual white balancing procedure including ambient plus video light (5.600 K) plus filter (rather orange than red). I just purchase a new equipment (Nikon Z6 in Nauticam housing) for flexibility reasons (photo and video options) and I still don't know how this camera performs when being equally operated relative to white balancing modalities. In a few weeks I will have nice test options in Raja Ampat and will let you know thereafter.
Best wishes!
Harald
@@haraldvoneick5727 wow njoy RAJA!!!
At the moment im also using ambient light filters for my video lights (i built it myself) and im looking to upgrade the lights. Keldan is probably too expensive.. i found lights that have tri color (white red blue) and you can use white and blue together. Would you still need an ambient light filter? 🤔 im unsure on one hand youd make the color temperature of the light very cool so maybe no ambient light filter is needed. On the other hand youre not removing the red light spectrum.. probably will build an ambient light filter myself later on just curious if i need to 😅
I don't really know the brand, so dificult to say, as I havent tested. But I am assuming, that the Blue LED will be too cool and not strong enough. Keldan sure... expensive.. but they will outlive mutiple camera setups ;) good investion! One o fthe upcoming episodes will be Video Lights... stay tuned :)
@@ReefPatrol ok great :D what i meant was the light im looking at has thre sets of leds UV Red and white. youre right the blue light isnt too bright (~600 lumens) but the white light is 15000 lumens so if you combine these two you have a cool but very bright light...
@@simon1234567ful perhaps it will work, no idea :) try it out and let us know :) But I am assuming it wont be the color temp of ambient light... it will be some sort of 450nm blue wavelength.
Hi, do you know where I can buy a cheap 77mm red filter for the lens?
we dont use cheap redfilters :) but guessing on amazon or ebay. But you will have less quality with cheap versions.
What about the mixed lights problem if you are not using Keldan lights? You have to “invent” a blue filter for your lights if they are not ready for mounting a filter?
Something to do with the mixed lights if you do not use blue filters for your lights?
Thanks.
Well you will need to live with a bit too red oversatureted image. there is no other way. this is always the issue with mixed light. some lights you can swap the LED module to a more cyan colored LED. that is possible too (e.g. Keldan 8M) .
Reef, will you get acceptable results by white balancing with the mixed lights? Maybe using a translucent cap instead a white card, to avoid the reflections of the artificial light in a close card.
@@ramonc.214 dont do a mwb with lights on ;)
@@ReefPatrol can I ask you why not? It would make perfect sense to me... One would need to use a matt WB sheet to avoid reflections, but by logic it should work
