  1. Hi Burkhard, I checked your YouTube channel and ended up watching your videos with my wife most of the last Friday evening. We enjoyed them very much, especially Antarctica, Triton Bay and Tubbataha Reef. Very professional work! We like footage, music selection and editing. Regarding the 'Antarctica' video, from what I understand, it is straight from the camera. Is it right? The quality is very good. Is it actually HDR? Val
  2. Thank you so much for very useful tips and ideas, Thani. It is not too late, I am departing at the end of December. Val
  3. Thank you for your comment. It looks like I should abandon an idea of shooting in HLG.
  4. Thank you bill1946. I read this ARTICLE about a white card with "red" squares. I will probably include it in the test, but not sure if a red type would work instead. I could use a Magic filter for this purpose, if I figure out how to fix it to the slate. In addition, my fins are white, and I am planning to include them in the test. I guess, this could be helpful when filming in the 'blue', when the camera could not find a reference to something 'white' or 'grey'.
  5. Hello videographers, During my upcoming trip to Raja Ampat, I am planning to do a 'white balance' testing with the Sony camcorder NXR-NX80, and I am looking for help in putting together a 'White Balance Testing' Protocol. The equipment and camera settings that I will be using are listed below. If anyone wanted me to test any specific camera settings or their own preferred settings, please let me know. My intention is to do the following tests at various depths (say about 6m, 10m and 15m) at a patch of corals. 1. No Slate, just with WB to a Scene. Please note that this ARTICLE advises that "the use of a white balance slate is unnecessary [with this camera]. Accurate (or reasonably so) white balance is established by WB SET with any given scene" From my communications with Gates, and my recent experience in Philippines, it appears that if a scene has enough white (or green) subjects, the camcorder could do a quite accurate white balance with a press of just one button - WB SET. 2. Grey Slate 3. White Slate MY EQUIPMENT and SETTINGS: Camera: Sony camcorder HXR-NX80 Housing: Gates AX700 / Z90 with Gates GP34A Wide Angle Port and internal URPro Pink Filter (for green water) Video Lights: Keldan Video 8X 11,000 Lumen CRI 92 (5400K) with Keldan Ambient Filter 6BG for 4X/8X (This filter is recommended for blue-green water within a depth range between 4-12 meters) Camera Settings: 4K, 30 FPS, Picture Profile: BT709. I follow the following article for recommended camera settings: AX700-Z90-Housing-Recommended-Settings-R2.pdf Thank you for your feedback. Val Please check my YouTube Channel
  6. Thank you for your comments, bubffm. Could you please share a link to your YouTube channel? I would like to check your videos. Also, could you share your 'own profile' settings? I like your comment about using ND 1 filter setting on muck dives. I will try it. I did not try HLG setting underwater yet, but Juan Monterey from http://wetpixel.es/ uses it extensively with good results. He has the Z90 camera.
  7. Interesting comment about "open water and no bottom or reef" for water to be blue. I never thought about this. My recollection is that during my trip to Socoro Island, the water was very blue (there was no bottom or reef). Here is my video from that trip. I should admit that this video was not post-processed properly due to the lack of skills.
  8. Thank you for your comment and sharing your videos. On my next trip, I would like to test 6BG ambient filter and then make a decision about 12 BG filter. I would like to see how much I could recover in the post process. As much as I like Keldan product, I do not really want to buy the entire lineup of their filters.
  9. Thank you for your recommendation, Interceptor121. I just ordered a pair of GB6 filters, and I am planning to do some testing during my next trip to Raja Ampat in December - January. Thanks again.
  10. I am thinking of buying another set of Keldan ambient filters, but not sure if blue-green (BG6) or green (G6) filters would be better in my case. The one set of ambient filters that I have is B6, which is for blue water. With my Gates housing I have to URPRO filters - one for blue water and another one - for green water. I do not dive in cold water, but even in Raja Ampat the water is greenish. So, for diving in places like Raja Ampat would G6 (rather than BG6) work better with my URPRO filter for green water? I realize that it will never be perfect, but I am trying to be close. Thank you for your feedback.
  11. Great information. Thank you very much. I will look up at buying the 6 BG filters, and will experiment on my next dive trip.
  12. Thank you for the clarification. I have to re-read your article about the ambient filters. I see that, in addition to 6 BG filter, Keldan has 12 BG filter for a depth of 10-18 meters, but from your post I understand that you do not recommend using ambient filters below 12 meters or so (the limit of the 6 BG filter). So, in this case if I am using video lights I should not use red filter, and rather focus on subject that my lights could light up. Is this correct?
  13. Thank you for watching my video and your feedback, Interceptor121. I am not sure if I could blame Keldan filters for cold colours, as I used them together with the internal red filter. Most probably I over-did blue colour in post-processing. I will pay more attention to this in the future. Thank you again. Your comments are very valuable.
  14. Here is my first video using Sony camcorder HXR-NX80 taken during the last diving trip in Philippines this August: https://youtu.be/XZ2JvM6JXkI I have not mastered this camera yet, and on a few occasions I inadvertently used wrong settings (i.e. the internal ND filter was on on a few dives). Also, playing with different settings and filters resulted in some color inconsistencies between different clips. While I am still trying to master this camera, I will greatly appreciate constructive criticism and recommendations. The following equipment was used to make this video: Camera: Sony camcorder HXR-NX80 Housing: Gates AX700 / Z90 with Gates GP34A Wide Angle Port and internal UR Pro Red Filter (on most dives) and UR Pro Pink Filter (on a few dives) Tripod: Gates Tripod Diopters: SAGA +5 Diopter Achromatic Close-Up Macro Lens, and SAGA +10 Diopter Achromatic Close-Up Macro Lens Video Lights: Keldan Video 8X 11,000 Lumen CRI 92 (5400K) with Keldan Ambient Filter M1 (10-20m) for 4X/8X Camera Settings: 4K, 30 FPS, Picture Profile: BT709. I followed the following article for recommended camera settings: AX700-Z90-Housing-Recommended-Settings-R2.pdf In my decision to buy this camera and housing, I followed an advise from Juan Monterey, who convinced me through his articles that this Sony camcorder is one of the best cameras for underwater videography: http://wetpixel.es/mi-actual-equipo-submarino/ As I am shooting only videos, I found many advantages of going with this camcorder and the Gates housing, including but not limited to the following: No need to carry several lenses. With one wide angle dome and diopters you could shoot wide angle and macro on the same dive. Very good and fast auto focus Very easy (one-button touch) white balance setup. Ability to use HLG - Hybrid Log Gamma (In the future for me) Battery is good for four dives (about 4 hrs) One things that puzzled me with this Gates housing is providing a control knob for ND filters, as I have never been in a situation yet when there is too much light under water. Maybe someone could enlighten me about this. For all footage above water I was using iPhone X. Hope to hear your comments and recommendations on how to improve my videos. Many thanks and cheers.
  15. Thank you for your comment, wunderhorn. Any full frame camera is not easy to travel with, and this one as well. In addition to the housing, domes and lights you would have to bring several lenses. If you are interested in something that is easy to use and travel with, a GoPro or another action camera is probably your best choice. If you are interested in videography, you will need to buy a set of powerful video lights as well. It all depends what you want to do. I actually switched to a Sony Camcorder NXR-NX80 recently, which is easier to use and the footage is of better quality. The camcorder is fairly small and only one lens is required, but in combination with a Gates housing it is not easy to travel with. I will be posting a video that I shoot with the NX-80 from my recent trip to Philippines in about a week, and you could see the quality of footage.
