Polarizing Filters

[Streetwise]

I setup some outdoor tubs for my 80+ parents this year, and it has been a great way to visit in these times. I have had some fun trying to film the tubs, but my iPhone keeps focusing on the reflection of the sky and trees above, unless I put my body in the way to make a shadow. I tried an umbrella, but it was somewhat translucent.

I researched polarizing filters, and with new iPhones on the horizon, I didn't want to spend more on my current model.

I like using a gimbal, and I have a DJI Osmo Mobile 3, so I picked up the DJI Osmo Pocket, along with the Expansion Kit. I looked into various filter kits, since they just attach magnetically to the Osmo Pocket, which is super cool. I almost spent on a ten-lens kit, but held back and and picked the PolarPro Cinema Series Filter 3-Pack.

I did a test video late-Sunday with the middle filter, but the conditions were not great for testing. I got a definite reduction in reflections, but sacrificed brightness. I think I need more daylight, and I still need to try the other two filters.

The filters are circular polarizing filters, so I think you can rotate them. I only had a little bit of time to test before I had to drive back, but I'll update when I try again.

Cheers,

PS, photographers, take us to school.

In my experience, polarizing filters don’t help enough to justify the loss in light. Every combo we have tried resulted in footage worse than not using a polarizer. For ponds we find it more simple to just film underwater.

I was worried about that. I'll still play around with them to learn more. I'm glad I didn't go all out with the ten-pack.

I did some underwater tests with my iPhone a few weeks ago, but I left the case on, so the bubbles escaping that were pretty distracting, but fish and shrimp were quite visible. I tested with and without flash, and it seemed better with flash off.

What do you like for underwater filming? The Osmo Action, or one of the GoPro models, or something else?

Thanks!

I typically use my Iphone without a case for underwater filming. I have a go pro as well, it does fine, it's just the phone is always in my pocket. If I'm out in peru and such. I use both at the same time typically. Each of them have their own quirks.
