How would an 8 inch dome perform with an 16mm FF equivalent fast lens?

31 January 2015 - 08:32 PM

Hi there,

I am planning to use the Zen 8 inch dome and I am worried about corner sharpness at the widest aperture of the lens. My setup will be consisting of a FF Canon 16-35mm 2.8 LII lens with an ultra speedbooster for Sony super 35mm sensor. The lens will be equivalent to 11.36mm FF with f2 aperture.

I will be shooting in ambient light (no video lights) and at the widest & fastest f2 aperture most of the time.

The closest I found was a good review by Ryan Canon for Zeiss Touit 12mm 2.8 behind a 7 inch dome. But that was still photography and I "think" is taking with flash at medium f-stops.

I would appreciate any help.

BMPC 4k clip shot in a custom housing

09 August 2014 - 02:34 AM


I have been working on a custom housing which was designed by me and executed by a workshop in Dubai which I will share the details later

In a couple of dives I wanted to test the new housing and firmware 1.9. Let me know what you think.

It was a drift dive that made it quite challenging so I used stabilization in resolve 11 for few shots. The clip is rendered at FHD.

I will try to post a 4k version on you youtube, any advice on what's the best setting? I am using Resolve 11

Black Magic Production Camera underwater footage

28 July 2014 - 01:05 PM


Finally got time to play with Davinci Resolve and produced some footage.

This video is underwater test for Black Magic Production Camera BMPC 4k. It was shot by me in a custom housing. It is all shot with ambient light - no artificial lighting was used. Visibility was not good due to plankton and particles. Not really a favorable test conditions
The video was captured in 4 dives into 2 different seas.One dive was done in the Arabian gulf (first clip) and the rest are done in the Gulf of Oman. It is hard to color match two characteristically different seas but I tried :)
I ended loving this camera due to two factors: Crisp details at 4k & Global Shutter. There is something magical about the movement/motion the global shutter captures. Or at least that is what I imagine :)
Despite the "noise" people are making around the Fixed Pattern Noise, the last clip of the clown fish is shot just at sunset and I did a simple noise reduction on it and I believe it is useful. This is before the 1.9 firmware release which makes the camera better at noise handling.
When coupled with a fast lens, this camera in the right hands can make magic :)

The video is broken into3 clips divided by surface shots of land/mountain scenes as follows:
+ All the clips are shot using Sigma 18-35mm 1.8 lens
+ All clips but second clip (barge wreck) are recorded in ProRes using firmware earlier than 1.8
+ Second clip is recorded using firmware 1.8 and recorded in RAW

Rendering was done at full HD using Davinci Resolve. Make sure you play the FULL HD version.
