In Topic: Review : OrcaLight SeaWolf 22,000 Lumen Video Light

Nice review Stuart. I've also been playing with the light in the Maldives, but didnt get as much chance as I'd hoped I would to use it. I will post some samples when I'm back home in a couple of weeks.
In the meantime I wonder if this review might get more of an audience in the Video equipment section- Drew?

Hi  Jim,


Thanks for the thoughts. I'll get in touch with Sharkwatch Arabia, I actually already know many of those involved. 

 Just found out it's mentioned in Fishes of Oman by Randall, as possibly having been described in Oman in 1944, but misidentified as Trygon gerradi




In Topic: BMPCC underwater filming setting

Hi Edmond, 


Its most beneficial to use a shutter angle around 180 degrees for best looking motion blur. If you shoot in a 50Hz environment then its good to use 172 because that will reduce flicker around artificial light. This has no consequence underwater where you would use a dc light source. 


Regarding kelvin I'd use a warm rather than cold setting so that you have some information in the red channel to work with when shooting without lights in prores (I recommend RAW for best results). That said I'd recommend you use a K that corresponds to your lights when using them and shoot raw when you are shooting without lights.  


I shoot raw for WA and prores for macro with lights. I use a daylight setting for my kelvin when shooting prores. 


Regarding the cards. There is still just one out there that supports RAW recording so the choice is kind of limited INMO.


Happy shooting,


Strangely enough, I have experienced flickering issues with powerful LED lights underwater, which could be corrected with an adjustment to shutterspeed. I experienced them at 1/50th sec with mangrove lights. It's not really a problem so long as you notice it underwater and correct it!

Hi Espen,


The lens itself is pretty good wider open. If you're shooting raw, as I do on the 5D Mark III (with a different lens), it's pretty easy to get rid of CA in post- I just used lightroom, and apply to all frames. 

I'm guessing the Tokina would be best with a 9inch + port, then you could probably use it wider open. Then there are the various fisheye options, but not always an ideal look for video....

Its a production camera and not really made for run and gun shooting. If I was to go that route I would simply download a days work into resolve adjust WB, exposure and tint and then output to prores. Then delete the raw. Minor tweeks hold up well with prores for the final grading. 


For me the most difficult thing would be to select what glass to use with an EF mount no less. Kind of wish it was a e-mount with a 12mm Zeiss for WA.

Anyone know what the red guys use for the epics?



I know some guys who have been shooting underwater with the Red Epic and the Tokina 11-16mm. It seems to be pretty sharp with a big dome- and I've been happy with it on the 7D. It's better at f8 and beyond.
