Wollensak and JML lenses in Caribbean sea islands

Hello,

Here is a little video made in two little islands of the Caribbean Sea, Providencia and Santa Catalina.

I use my modified Yi 4K+ with a Wollensak 1/2" f/1.5 (during the day) and a JML 17mm f/0.95 (during the night)
The underwater footages were just made with a basic action cam.

Tips about the Wollensak lens : It's too soft wide open. When we stop down it starts to shine. It performs the best at f/8
The JML is quite sharp but has some purple shifts in the highlights that needs to be corrected.

I also used a bitrate mod on the Yi to increase it. It's originally 135mb/s and I pushed it to 220mb/s

Nicely done! A few observations: handheld shake made me think of using deshaker in PP, green underwater shots reminded me of using those special green reducing filters for that.

That turtle good catch. I would be interested in more that night scenery footage. Good music what was they played, indeed.

Thanks,

Yes, I didn't take my gimbal because of the strict weight limitations in the plane. So I just used a monopod and used a bit of Premiere warp stabilizer in some sequences.
For the underwater scenes, I reduced a bit the green in the highlights in post-processing, because it was too greenish to me. I'm not an expert of underwater scenes. It was my first time at this exercise (and I'm quite bad at snorkling too).

Thanks, I have other shots of the nightery scenes that I eliminated for ambient sound noise and because I was eating at the same time, so I took very few of it. It was all took with the JML at 800iso 24fps 1/30s shutter speed. I did not applied a noise reduction for it.
