View Full Version : Underwater cmos video camera
Kenneth Johnson September 13th, 2008, 02:36 PM Has anybody had any experience shooting underwater with a cmos video camera??? I just had my pd170 stolen and am going to upgrade to a HD camera to be used for underwater. Just wondering if the video camera would have any unique problems working with this type of sensor compared to the ccd sensor

Lloyd Coleman September 13th, 2008, 04:28 PM I've used a Canon HV10 with great results. No unique problems that I am aware of.
John Miller September 13th, 2008, 05:08 PM I'm happy with my Sony HDR-HC1...
Ron Chau September 14th, 2008, 11:16 AM No problems here with an Sony FX7.
Some of my UW videos can be seen on vimeo:

Dave Allen September 18th, 2008, 01:00 AM Although is is said charge coupled devices render better, I have seen plenty of stunning CMOS chip underwater video, and Ron's is a perfect example.

Hi Ron,
incredible! How didyou manage to get this vivid and realistic colors? Filter? White balance?
Ron Chau January 26th, 2009, 08:49 AM HI Sascha,
Yes, underwater filter and manual white balance. The filter is a standard accessory for UW shooting and most housings come with it. Manual white balance is less common, but worth getting. Thanks, glad you liked my videos.

Other stuff on the site is with a Canon XHA1,
I agree with Ron regarding manual white balance... HDV doesn't hold up super well to extensive colour correction
Mike Hardy February 23rd, 2009, 02:05 PM I love this little camera.
This is a promo I shot for the Dive Company in Egypt. Topside AND underwater footage alll shot with the small, single CMOS Canon.

Andrew Davies February 25th, 2009, 04:55 AM How did you manage with the flipped image?
John Miller February 25th, 2009, 06:35 AM I have an Ikelite housing for my HC1. It has a small widget hooked into the LANC port such that when a switch is closed, the LCD image is mirrored. I find the flip-out mirror a bit small, though, especially compared to my old Light and Motion housing.
Mike Hardy March 2nd, 2009, 06:56 AM How did you manage with the flipped image?
Hello Andrew. ABISMALLY, would be the answer to that. In fact, even if it HADN'T been flipped, I would have struggled to see it. I simply used the eye-piece, which is quite good.

so cut pasted and reposted hope it gets to you.
I've been shooting uw since 1986, now on 5th set. I have many hours uw with these CMOS sony cameras. HDR-HC1 and HVR-A1U. They provide a great HDV image in reasonable low light situations. They are basically identical, same CMOS etc . A1U has two pro features 1 assign button, I assign to white balance. the other is balanced XLR mic and jacks. Both use same GATES housing. A1U is about $1K more, still available. Was the "2nd camera" of choice by Hollywood year it came out. Great image, small, mounted on cars, heads, so far a rugged unit, just watch moisture around it.
You can find HC1 on ebay. The only negative and this is small issue, you must take camera off uw housing mounting bracket to change batteries...same for change of tape, which tape normally ends before battery. Dream world top loading ...hint Sony if anyone is listing same problem when mounted to tripod mount. Here are a few other insights.
1. very small form factor, weight really adds up if you go up to larger form factor like the Sony FX1 and newer versions. A1U+Housing+6hr battery, no lights is 26 lbs, in water even with buoyancy factor of housing still about 10 negative. With today’s flying regs and fees for weight this too is worth mention.
2. smaller size makes for much easier getting into places and really makes a difference the wall you push through water.
3. cost of everything, camear, housing, batteries, goes up dramatically for the 3CMOS versions
If you do go to one of the newer tapeless CMOS system, I would like to hear about your experience. Good luck and safe diving.
Marcel Steuermann March 26th, 2009, 06:48 AM Yes, camcorders using CMOS are really worth buying. After using a Sony HDR-HC7 a couple of times, being filming in Corsica and Sudan underwater I can also recommend this type which is very often underrated to my point of view. Still I have to admit that you have do some colorcorrection and you have to push the contrast and reduce the brightness in post-pro. I did a video about the wreck UMBRIA and the conditions were not the best to film. Have a look and judge for yourself what the HC7 can produce.
