  1. Thank you for your feedback. You are correct regarding Alex comments, and your guess of how I swim on the subject is correct. I think it would be safer to be stationary while using lights. Also, would you say that position of video lights for video should be similar to position of strobes for photography? To me, it should not be any different. Could I just follow recommendations for strobes positioning?
  2. Thank you for watching my videos, your perspective and recommendations, aviator8. I live in Canada (Toronto) and I do not like diving in this area. I am trying to make three dive trips each year, and I should definitely use a more systematic approach to improve my skills. Thanks again
  3. I have very good and powerful video lights (Keldan 8X), and I tend to over-use them. I started to use ambient light filters in combination with a red filter on a lens, and I am getting more pleasant results. I am stragelling a bit with proper positioning of my video lights. Some recommend to put lights in line with the camera, some slightly behind the camera, others - just in front of the camera. Another question I have is about overlap of lights. Some recommend to overlap light cones (so that the subject is illuminated by both lights), but Alex Mustard, for example, recommends to have light cones apart. I am collecting all this information piece by piece, and trying a few different things every time, but it takes more time than I hopped. Thank you for your comments, TaxiDriver 14.
  4. Thank you bubffm. I will take your comment as a compliment. Thanks again. I am following Vanessa's course, and eagerly waiting for more advanced topics. I feel that I need to fine-tune many things, mostly related to lighting.
  5. Could anyone recommend a good underwater videography course online, liveaboard or at a resort? I attended one at Lembeh a few years ago, and looking for something else, more advanced. Many thanks.
  6. Many thanks for your reply and a link to the article. Great staff! Very useful information. I have the same video lights with ambient filters that you tested. I need to re-read your article to better understand all fine points.
  7. When I will be using color correction filter I will either do not use lights or I will use lights with Keldan Ambient filters.
  8. Thank you for the info. I will check it out.
  9. Hello, I am looking for an advise on selection of an internal color filter(s) for Gates AX700 / Z90 housing. This housing comes with a red filter, but the filter could be changed for another color. Seller recommended me to buy both red filter (for blue water) and pink filter (for green water), as according to him "Water conditions vary due to time of day, currents and particulate in the water." Among other recommendations on internet, here is a typical recommendation: Pink Filter (for use in green water), OrangeFilter (for use at depth up to 15m), Red Filter (for use at depth of 15m or deeper). Could anyone recommend a good article on color filter selection for UW videography? I am diving only in warm water, i.e. Indonesia, Philippines, Caribbean, etc. Also, Gates' color filters are quite expensive ($138US), so I would like to know if there is another manufacturer of good 'pro' quality color filter elements? Thank you for your recommendations.
  10. Nice footage. Did you do any post processing?
  11. Here is my latest video "Diving in Andaman Sea" from our last trip to Thailand and Myanmar in April. https://youtu.be/vJ4-l2nS7QQ All underwater footage and some above water footage are filmed with Sony A7Rii. I also used iPhone X for some above water footage, and Mavic Pro - for drone footage. I will greatly appreciate any constructive criticism. Many thanks
  12. Great tips! Thank you, Interceptor121. I did not use zebra, but will use in the future. Thank you again.
  13. Thank you for your recommendations, dreifish. Everything make sense now. I will follow your recommendations in the future. Regarding picture profile, I used standard, plus I did some color correction, but did not change saturation. By the way, I checked your YouTube channel, and watched many of your films about Raja Ampat and Komodo, and was very impressed. I wish I could create something close to it one day. Great films! Thank you again, Val
  14. I appreciate your comments, Interceptor121. Clipped highlights are the result of my inexperience with these powerful lights. I do not recall using any filters on that trip. I was playing in between Underwater WB or Auto WB setting. At that time, I did not know that water in Raja Ampat is blue green. In most cases, I had lights at 100%, and I was adjusting aperture and/or ISO. Would you rather recommend to start with lights at lower level (say 50%), keep aperture say at 8 and play adjust ISO around 800 to avoid clipping highlights? Thank you again.
  15. YouTube basically allows you to use any music irrespectively where you get it from. They will just put a 'copyright claim', put a reference to a publisher in the description, and collect some revenue from adds. I used to buy licenses, but they were putting 'copyright claim' anyway, so I had to spend a lot of time convincing them that I purchased a licence. Unless your video is a promotional video, you should be okay without a license.
  16. Great footage! Thank you for sharing. It felt like that a bit more contrast would help. I have exactly the same video lights and ambient filters, and I do recall that they recommend to do white balance (WB) every time. Did you do WB underwater? Re: Alex4D Channel Mixer, I thought that it will not work with 4K. I spent some time playing with it, but then gave up, and started to learn more fundamentals of color grading. I agree with the above comment about shooting with natural light in at shallower depth and good light conditions. I know one professional videographer who shoots in 8K for BBC, National Geo, etc, and he always recommends against using lights in such conditions.
  17. Hi bubffm, Thank you very much for your reply and tips. Thank you very much, wydeangle. Many thanks, Jack. I appreciate your reply very much. Thank you very much Tom. It looks like a very economical solution. I will take a look at it.
  18. Here is a link to a short video "Happy Women's Day From a Diver" in advance of International Women's Day on March 8th. I posted this video a few days earlier, as I will be away on the Ray of Hope Expedition, diving in Andaman Sea next week. Best wishes to all women, divers and non-divers. All footage is filmed with Sony a7rii camera. https://youtu.be/VeWGMLk4DGU
  19. Thank you, Chris. My current camera, Sony A7Rii, does not allow to do custom WB underwater. So, it is a bit tricky.
  20. I have a question for owner of Gates housings with threaded ball mounts on the top of grip handles. Could you please tell me how significant is a problem with threaded ball mounts becoming loose? In the review of Gates AX700 / Z90 Housing (Sony FDR-AX700 / HXR-NX80 / PXW-Z90 / PXW-X70) by Karena and John Ellerbrock (owner of Gates), they pointed out on a problem with threaded ball mounts: "Ball mount on the top of the grip handles have been ¼-20 threaded type for over 20 years. They worked well, but have a tendency to rotate loose. Especially when re-positioning GT14 lights. So we fixed it. Within 3 days of our return to the office, a new design was done and headed to production. No more loose / spinning ball mounts." ​To address the problem, they developed no spin ball mounts, which are sold separately for $94 a pair (!). How big is this problem to spend additional $94 to address this design flaw? Also, have you experienced any other problems with this housing? Many thanks.
  21. Thank you for sharing, David. I like your video, colors are balanced nicely and music selection is good as well. Have you used video lights or a red filter? I do not see shadows anywhere.
  22. Chris, thank you for your review and comments. Regarding reds/oranges, I am probably overusing my powerful video lights. I am still on a learning curve and have to find the right balance. I started to use a combination of a red filter on a lens and a blue ambient filter on my lights. This combination works well in some situation. I am planning to put a short video to share the results. On another hand, I am trying to find an answer to the question "What is a true color under water? How much of red, purple or orange is actually over there". Most divers do not see real colors under water, and as you know the deeper we go the less color we see. When I started using really powerful video lights (I bought them just before my trip to Misool) I started to see all those fantastic colors; and in Misool the whole group was following me because they could see everything in color. By the way, I checked your website and instagram account, and I love your photos. Seadragons are my favourites, but I've never seen them 'in person'.
