  1. Thank you very much for your nice comment Kraken de Mabini. Val
  2. Hi Arellano, Thank you for your comment about my video. If you are planning to take a liveaboard, I would recommend you to check reviews at Undercurrent. If your choice is a resort (this is my preference), my recommendation would be Papua Diving Resorts: Sorido Bay Resort and Kri Eco Resorts. They are pioneers of diving in Raja Ampat and located on Kri Island in a middle of Dampier Strait, which offers the best scuba diving of Raja Ampat. You could watch my videos about Sorido Bay Resort and their founder, Max Ammer, using the following links: https://youtu.be/rY8pi6XgZMg https://youtu.be/vcmAxOhLgEM Also, here is the LINK to my trip report posted at Scubaboard. Enjoy your trip to Raja Ampat. Thank you, Val
  3. Please find the following link to my new 4K video "COLORS OF RAJA AMPAT IN HDR", in which I was trying to show magnificent colors of the Raja Ampat's marine life, biodiversity of which is the highest recorded on Earth. It's simply overwhelming. You could watch the video in SDR quality or in HDR quality on an HDR-enabled television, tablets, phones or computer screens. All footage of this video was shot in 4K using Sony Camcorder HXR-NX80 with picture profile Hybrid Log Gamma (HLG). For camera setting, I followed recommendations of the following article: AX700-Z90-Housing-Recommended-Settings-R2: https://www.gateshousings.com/wp-co...AX700-Z90-Housing-Recommended-Settings-R2.pdf: Camera Settings: 4K, 30 FPS; Picture Profile: PP10; Gamma: HLG2; Color Mode: BT2020 Thank you for watching, and please let me know if you have any questions or comments.
  4. Here is the link to my new video - the Episode 2 of my series of videos about dive sites of Raja Ampat, which will bring you to the Blue Magic Dive Site at Dampier Strait in West Papua, Indonesia. If you enjoyed the video, please LIKE it, leave a COMMENT, SHARE and SUBSCRIBE for more exciting travel videos! In this video I used 4K underwater video clips shot during our two stays at the Sorido Bay Resort in December 2018 and January 2020. All 'manta ray' clips and a few 'fish' clips were shot using Sony A7Rii camera in 2018; and all other clips were shot using Sony Camcorder NXR-NX80 in 2020. I will greatly appreciate a constructive criticism of this video. THANK YOU FOR WATCHING AND YOUR COMMENTS! https://youtu.be/7kyn7nkcfEQ
  5. I am glad to hear that you like it. You may want to keep an eye on my YouTube channel, as I will be posting video "Raja Ampat - The Last Paradise" in a week or two. This will be Episode 1, which will be focused on the Sorido Bay Resort and diving at Cape Kri.
  6. Thank you very much Kylie. I am glad you like it. We' ve been to Misool Eco Resort as well, but we like Sorido Bay Resort better, and planning to come back again as soon as travel is allowed. I am actually finalizing my movie about Sorido Bay Resort, and, if you are interested, you could follow my YouTube Channel to get unbiased information about this resort and diving at Dampier Strait.
  7. Have you been dreaming of Raja Ampat recently? Me too.So, I created a video DREAMING OF RAJA AMPAT to share our memories and dreams about the breathtaking Raja Ampat. In this video, I used footage from our two most recent trips to Raja Ampat. Both times we stayed at Sorido Bay Resort (Dampier Strait), which is our favorite dive resort. If you are interested in more technical details, please keep reading below. On the first trip I used a Sony A7Rii camera, Ikelite housing and Keldan Video lights 8X 11,000 Lumen CRI 92 (5400K). Sony A7Rii had some problems with autofocus and did not allow to set WB manually. On the second trip I used the following equipment: Camera: Sony camcorder HXR-NX80 Housing: Gates AX700 / Z90 with Gates GP34A Wide Angle Port and internal UR Pro Red Filter 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, and on several dives - HLG picture profile. For camera settings, I used recommendations from the following article : AX700-Z90-Housing-Recommended-Settings-R2.pdf HDR clips were converted to Rec.709 color space using the following two methods: 1 - FCPX HDR Tool HDR to Rec.709 SDR, 2 - Leeming Camera LUT Pro Sony A - HLG to Rec.709. For reasons I could not explain, FCPX HDR Tool worked better for some clips and Leeming Camera Lut worked better for other clips. Juan Miguel Núñez Arellano provided me invaluable guidance and mentoring in shooting and grading HLG footage. You could visit his website (http://wetpixel.es) to learn more about underwater videography in general and about using HLG in UW videography. Juan's videos could be found at the following YouTube Channel: https://www.youtube.com/c/JUANMONTEREY/featured
  8. Thank you for watching the video and your comments, Diggy. We've been to Sorido Bay Resort twice already and both times we stayed for 18 days. It was just perfect. We loved this Paradise, underwater and above. I would stay longer, but not less than two weeks. Val
  9. I am happy to share my latest video-interview with Max Ammer, the pioneer of diving in Raja Ampat, West Papua in Indonesia. About 30 years ago, Max came to Raja Ampat in a search of World War II relics. This is a story about how Max built the very first dive resort in Raja Ampat - Kri Eco Resort, and later - Sorido Bay Resort, about conservation efforts of Max and his partners, training local people and building the very first electrical boat in Raja Ampat. Video is shot with Sony NX80, and a few clips with Sony 7Rii. ENJOY. https://youtu.be/vcmAxOhLgEM
  10. I watched your video on different monitors (SDR and HDR), and I like the quality. I enjoyed the quality on my big HDR TV more of course, but overall it is very good. Thank you for sharing. I hope you would keep experimenting with HLG. I would be interested to see your your video from that trip recorded in Rec 709.
  11. Further to my previous two posts on this topic, PART 1 and PART 2, I practiced with grading of my HLG footage in FCPX a little bit more. So far, I found that the best way to grade HLG footage for SDR TVs and screens is to grade them on Rec.709 Timeline using the following LUTs: Lemming Camera LUT 'Pro Sony A - HLG to Rec.709 and Custom LUT 'Quicker - Neutral Film Brightest'. After applying LUTs, I graded clips as usual. It does not take more time and does not require a special monitor. There are probably other and better ways to grade HLG footage, but I do not know them yet. Here is the link to the video Shooting HLG Underwater-Grading on Rec 709 Timeline You could see depth, ISO and F values of each clip in captions. Another version of this video, graded in Premier Pro, was kindly put together by Juan M.Núñez It would be interesting to know your opinion about the quality of images on SDR screens. Also, if anyone would like to play with raw HLG clips that Juan and I used in these two videos, please let me know and I will share a link to the Dropbox.
  12. I watched your video on my HDR TV, and, in my humble opinion, it shows good potential of using HLG underwater. I appreciate that you do not have proper lights, but when there was sufficient light, I could see very rich, good colors.
  13. Thank you, Lionfi2s. I appreciate your feedback and recommendations. I will definitely try them.
  14. Thank you for watching my videos and your valuable feedback. I will try your recommendation "use the PQ but apply some small improvements than go back to HLG deleting the HDR tools adjustments".
  15. Inspired by discussion triggered by my PREVIOUS POST on this topic, and after watching an interview with Alister Chapman, I experimented with HLG footage a bit more (without a special HDR Monitor). This time, rather than converting HLG clips to Rec.709 clips, I created a new video in true HLG format, to see how it would work for both HDR and SDR TVs. I actually ended up creating two versions of the same video. Both versions were created with the same Video Codec: ‘HDR TV’ version – in this version I wanted to see what would be the quality of the video without any color grading (okay, almost no color grading) ‘SDR TV’ version – in this version I did some minimal color grading to get an image quality on an SDR screen similar to the one an HDR screen (in my subjective opinion). I selected several video clips that I shot in HLG (BT2020 color space) at different depths (from 5 m to 35 m) and did the following (mostly following Apple’s recommendations): 1. Created a library in FCPX and set it to Wide Gamut HDR 2. Imported all clips to this library 3. Slightly adjusted Midtones by lowering brightness to -0.1 (this what I understand Alister Chapman has recommended) 4. Slightly adjusted Hue vs Hue of Hue/Saturation Curve of a few clips to change water color from greenish to blueish. 5. Slightly increased sharpness (3.78) 6. Applied HDR Tool (PQ Output Tone Map) 7. Shared the project as a Master File, using Video Codec: Apple ProRes 422 and Wide Gamut HDR - Rec. 2020 HLG color space 8. Uploaded the Master file to YouTube As you can see from the above steps, I basically did not do any color grading, and all above steps took me only about 5 to 10 min, as I was using adjustment layers, to which I applied most adjustments, rather than to individual clips. Here is the LINK to the 'HDR TV' version of the video. When I watched this video on the my HDR TV (Samsung Q80R, 2019) I was quite impressed with its quality. Then, I watched the same video on my old plasma TV and a 2-year old HDR TV, on iMac, on MacBook Pro (2018), on iPhone X, and on my new Dell laptop (2020). I noticed that colors on these screens got 'washed out' a bit, compared to colors on my HDR TV. So, I decided to create another version of this video (‘SDR TV’ version), in which, in addition to the above steps 1 to 8, I made the following adjustments to increase contrast and brightness: 1. Increased brightness of Highlights up to +0.21 2. Decreased brightness of Shadows down to -0.22 for some clips 3. Increased saturation of Midtones slightly As a result, I got a video with quality quite comparable to the ‘HDR TV’ version (in my humble opinion). As such, it appears that for people who do not watch YouTube videos on an HDR TVs the second version ('SDR TV') would work better. Here is the LINK to the 'SDR TV' version of the video. Most probably, quality of this second video could be improved further by making some additional adjustments, but I already see that shooting in HLG underwater could produce very good quality videos (at least to my taste) without much grading and without a special HDR monitor. I should note, however, that I am not sure how good could be quality of underwater footage shot in HLG picture profile using other cameras. With SONY cameras like the one I have (Sony FDR-AX700 / HXR-NX80 / PXW-Z90), it is very easy to set manual white balance underwater with just one click, and I did it for every single shot. Sometimes, however, when there is not much ‘white’ color in a scene to be used by the camera for reference, you have to experiment a bit, and this is where the mastery is. I am not there yet, and I need to practice more to improve this skill. Also, I would like to mention that I am not an expert in HLG, and if anyone is interested in learning more about advantages of HLG I would refer to experts like Alister Chapman. If you would like to learn more about using HLG in underwater videography, I would refer you to J. M. Núñez’s WEBSITE. Juan has tonnes of experience in shooting HLG underwater, and his website is full of very useful and practical information and tips. Please share your opinion about picture quality of the two versions of my video on HDR and SDR screens when you have time. Thank you all. Stay home and stay healthy. Val
  16. Thank you, Interceptor121. I always like your posts. They get me to research, think and experiment more.
  17. I just posted a short video which Juan M. Núñez helped me to grade and export using Encoder Adobe Premiere MXF Intra 300 4.2.2. I shot all footage used in this video, but because I do not have an HDR monitor, Juan M. Núñez, who has all right equipment, kindly agreed to grade a few of my clips and put this short video together, for which I am very grateful to him. You could visit Juan's website http://wetpixel.es to learn more about underwater videography in general and about using HLG for underwater videography. Also, you could visit his YouTube channel at https://www.youtube.com/channel/UCnKjMMMzc7HFmFwSy40Nt4g
  18. Thank you for your feedback, Lionfi2s. I appreciate it. I am still learning and experimenting, and honest feedback is always very helpful.
