I have both the CMC-1 and Aquako IV. On the Panasonic LX100, the Aquako IV is not usable because the 52mm native thread on it cause vignette. If you don't plan to get into Super Macro, then the CMC-1 is good because it's cheaper and lighter then SMC, and you can stack another diopter on top of the CMC-1, but the working distance will be really really short.
Not sure what to expect in January. I was there in mid-late March. Hairy frogfish is easy to find, so is mantis shrimp with eggs, the best place to find sheep nudibranch is at Secret Bay. I also saw two clownfish egg patch that time of the year. Someone from this forum when to the house reef of Crystal Blue in May and saw flamboyant cuttle fish eggs.
Thanks everyone! I was a bit concern about over use of timelapse, but it's the best way to tell the activity, both at the dock and the gear up area.
Basil, I did use Magic Filter in two dives. It turned out the weather in Anilao made it pointless when I was there. The morning sun was okay in Anilao, but the afternoon was overcast. For Magic Filter to be effective, the sun should be high and behind the diver, mostly between 12 noon to 3pm. So I didn't use Magic Filter other then that 2 experiment dives. All my wide angle shot were shoot with custom white balance using a gray reference card. I take a white balance reading everytime before I start the recording. Many people use sand, hand, or save the white balance setting into the preset based on depth. I don't do that because light condition constantly change, especially if there is cloud around.
As for picture profile, I use "Scenery", it's the best setting to bring out the blue color for Panasonic, however, Chris Parson made a comment that the Scenery setting makes the yellow too much, and I'm starting to notice that. But I think I can turn down the saturation at post if I need to.
For camera setting, I follow everything here as it's the only site that has the most detail info about LX100 menu::
I didn't mess with the contrast curves in the camera.
When come to editing, I edit in 4K and output my final video at 80 mbps to upload to Youtbue. 80Mbps is more than what Youtube will need and they will re-compress it. 80Mbps is also good enough for me to archive. Also, during editing, I only change shadow/hightlight, there are a few clips that I might need to do a "Fast color correct" or adjust brightness (I use Premiere Pro CC).
Red Sea has great visibility! Make sure you get the blue color right, also, when come to shooting video, shallow is your friend! You get the best ambient light. With the LX100, try not go above ISO400, at ISO800 you will see noticeable noise at the blue water area but the coral and everything else would be fine.
Secret Bay is filthy at time....... yeah I feel for you. I spent 10 days at Anilao, saw used diaper, women maxi-pad. The second last day we stopped at the Secret Bay beach because the DM need to stop by his family's place a bit, I jokingly said to my fellow divers that I have seen all human waste trash possible, accept for used condom....... long and behold, one of the ladies used a tree branch to lift up a used condom waving at me. Good thing I wasn't in the water, I burst into laughter and it was just totally silly moment.
Anyway, Nicool, if you dive rebreather, contact Mike at Crystal Blue. In our trip, one of the guys dove rebreather. He got assign to the boat where everybody has best air consumption. Crystal Blue don't have pure oxygent tank but I was told when the rebreather guy need oxygen, they have to go out about 35 minutes away to pick or refill the oxygen for him. They go out of their way to accommodate the diver. I'm sure high tips is expected. I feel sorry for the DM on the boat that has rebreather diver, I heard that the DM ran out of air almost every dives and at one point he had to buddy share air with one of the diver while still pointing out creature to all the divers, talk about dedication!
