OM-D E-M5 video: Annoying background noise

23 March 2014 - 01:41 AM

When recording video with my E-M5, I've noticed I have a weird background noise to all of my videos. It can be heard here. First time, I believed it was the engine of the boat we were diving from, but as I've been taking more videos, I hear it on every video. It's not there when I take videos topside, without the housing.

 

I've been experimenting a bit topside, and it seems as if the sound comes when the camera is moved. When I'm supporting the housing on my knee, it disappears shortly, but as soon as I'm panning it returns. It seems to be the same whether or not I use stabilizing, so I'd appreciate tips on possible causes and ways to avoid the noise. It's pretty annoying, and I'd like to be able to use the underwater sounds as a background to the soundtrack.

 

 

 

Gear setup: OM-D E-M5 in Nauticam NA-EM5, M Zuiko 9-18mm f/4-5.6, 4" dome port, Inon Z240.


Only a couple of weeks left...

04 March 2014 - 06:03 AM

...to algal soup in the surface and crappy viz. If the local waters behave as they use to, for which, incidentally, there's no guarantee given the freaky weather we've had this winter. But that's another issue.

Right now we're thoroughly enjoying the last remainders of winter clear water, with the light finally coming to the high North. Here at 63 degrees North, the day is five and a half hours longer than at New Year, and the sun is actually rising significantly above the horizon again. Bliss! Too bad it's only a few weeks left to the spring algal bloom with pea soup viz, but right now we're enjoying maybe the best conditions of the whole year: 4-6 degrees (Celsius) water, 15-20m viz, good light. And I've been lucky to be able to work on my WA compositions the last couple of months:

Where/how do you stow the neoprene dome cover?

20 February 2014 - 11:35 PM

Even if I thought I'd been rather careful with my camera and housing, I've gotten a few light scuff marks on the glass of my (Nauticam m43 4") dome port. It's probably happened on entry/exit during shore dives, when I occasionally have had to have the housing just hanging from my BCD, and I guess the dome has rubbed against my BCD on occasions. So far I haven't noticed any image deterioration underwater, so the scuff marks are probably masked by the similar refractive index of the water and the dome material. However, from now on I'm keeping the cover on the port until I'm safely in the water and have descended, and I remove it when I recover buoyancy, do the post-descent check on myself and the gear and extend the strobe arms which I keep "wrapped" around the housing while I'm on the surface.

 

The problem is: Where do I stow the port cover while underwater? My suit's thigh pocket is occupied by my dSMB and spool, and I'm worried I'll lose the port cover when I pull out the dSMB to shoot it. My BCD harness is already pretty cramped with "stuff" (octo on the right shoulder D-ring, backup light clipped to the left shoulder D-ring and bungied to the shoulder strap, SPG - and camera safety tether - on left hip D-ring and right hip D-ring is a bit unaccessible due to a gear pocket mounted on my right side). What do other people do with the cover when they're diving - unless they leave it topside?

 

Also, since I'm diving dry, my current suit is... let's say "not too big" (I've ordered a new one, by the way) and I'm wearing a rather thick hood and 6.5mm 3-finger wetgloves, my dexterity and freedom of movement is a bit restricted compared to you guys diving a 3mm shorty with no hood or gloves. That calls for a simple solution which I just haven't been able to find yet.

 

Any tips or ideas?


OM-D E-M5 and 9-18mm in Nordic water

02 September 2013 - 10:12 PM

So my first summer with my OM-D rig is over, and since the lighting conditions will only get worse as we're closing in on the winter, I guess there won't be as much shooting during the coming months. I'm still in the learning process both on UW photography in general and with the OM-D rig, so I'd appreciate if anyone had feedback on my pictures:

First time in the Mediterranean - beginner in Ustica (Italy)

18 July 2013 - 01:10 AM

So, my first diving vacation is over, and I'd really appreciate some feedback on a few of the pictures I got.

The location was the small island Ustica north of Palermo in Sicilia, Italy, and the equipment was my brand new rig, bought this spring: Olympus OM-D E-M5 with M Zuiko 9-18mm f/4-5.6 in a Nauticam NA-EM5 with the 4" semidome port and one Inon Z240 on 5" + 7" arms.
