  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I think that the new norm will be batt. packs attached behind lights to minimize bulk and streamline the whole system. Lets see what Gates has in the next few weeks. Looks like they are in the same track with LED and battery pack and light heads all in one piece. I'm sure price will be much more competitive.
 
I use twin 13,000 lm, 100% CRI, 1h burn time lights. Look forward to hear when an upgrade is available :smilewinkgrin:

Are those the ones in a photo of yours with huge battery canisters attached to the already large housing? not being sarcastic, just making sure I know what we're talking about by the way.

Yes, they have three subject settings: medium, well done and burnt.

For liability reasons I have removed the "burnt" settings on my lights. :)



Even with developments in LEDs, there's no real magic in lights.

It takes x amount of power to produce y lumens.

For good stage/studio tungsten halogen you get about 28 lumens per watt

Hid/hmi is pretty steady around 64 per watt, fluorescent is in the ballpark.

LEDs just recently got reliably to hid level, and a few go to about 100 with special drivers. LEDs are attractive because of high color temperature, instant on and extremely long life BUT the problem is they have very poor color rendering index (CRI). The only really good ones combine multiple colors to get decent color rendering but haven't seen any from the usual suspects that do that.

The upside of tungsten as pawel mentioned is essentially perfect color rendition.

I've looked at and built pretty much all of these types and honestly the only time i'm interested is at the level of 150 watt/9000 lumens or more. And even there it isn't because it's better than the existing tungsten but simply a little longer burn time on equivalent batteries. Anything less has been pretty much marketing bullshine where endusers haven't had the ability (sometimes through lack of education but also lack of accurate specs) to do real comparisons. We get 28 minutes from a modern lithium ion pack and the same basic 350watt 9800 lumen compact lamphead (2.37diam x 5" long) that I've made for 27 years - perfect color rendition and easily filtered to 5800k or whatever you want with little or no loss in CRI. And these days that pack fits in an 8" long 4" cylinder or even smaller rectangular pack. And obviously they could be packaged even smaller since the bulb is only 2" x2.5 long with the socket and you could combine the pack and lamp into a unibody lamp head. I haven't done much with lights lately coz it's just too annoying and difficult to fight the bullshine wars.

Just rembember that they often quote 5800k color temperature or whatever but usually not the CRI because it's bad. Even though they are high color temp nominally they can be missing major portions of the color spectrum.

Ahhh, ...one of my most favourite.....helps you achieve very crisp results :biggrinjester:

Seriously, couldn't agree more about your take on u/w lights.

Not sure if we are talking about people, fish .... Or bacon - cause I likes me some crispy bacon and 350 watts from a 2" bulb will definitely do the job :)

Mark who? There was a mr. Thorpe many years ago in this forum, but he bought a Cannon and went all crazy with it and dissapeared into the so. pacific. Haven't heard since.....something like a Dr. Livingston.

Looking forward to hooking back up there Mr. Thorpe. Whenever you can bring your greens this way. In fact, join Adam and i on a possible excursion out this way with something we have cooking for a few weeks.
 
Mate, sounds like a plan. Have sold all items RED though, back to the stills and loving the new ViDSLR's. Hankering around with the 5DMkII now and getting some blazing concept water shots. All good. Whenever there's a need for another set of paws let me know mate. Would be good to shout at Adam again, in a Gladiator kind of way that is.

Cheers,
Mark.
 
Just shot a shot sequence for new USA tv series on NBC called ALPHAS..I showed up on set..they throw a new AquaticaCannon 5md11 housing/ camera/ dome port at me with a 10-22 lense and said jump in and film this swimming sequence of the shows star...I did not no one end of the camera/housing or lense with zero instructions and 10 minutes to play..after 3 hours of rolling around like a frog in mud I somehow got enough footage to make them happy..
In the future they will tell the camera/housing what to shoot and when to be back on the boat and throw it in..just another underwater miracle I guess..Kozzzzzz
 
Good Day to all,

For unexplained reasons I was unable to post for awhile.

Yes, we have new lights. Preliminary information:

Gates debuted new underwater LED lighting at the Blue Ocean Festival. The lights were developed in collaboration with Subaqua Imaging Systems Inc whose expertise breached all barriers in size / efficiency / light output. The VL8 is for the recreational and Prosumer users. The VL24 is suitable for broadcast / cinema and un-tethers professional cameramen from surface supplied lighting. Both lights are self contained with no umbilical, and can be detached from their arms and placed away from the videographer. With their neutral buoyancy they will delight the SLR videographer as well.
Preliminary key features include:
Models: VL8 and LV24
Power modes: Full and Half
Burn time: 1 hour full, 2+ hours half
Lumens output: > 2300 VL8 >7000 VL24 (per LED manufacturer rated output)
Buoyancy: Neutral
Color Temp: Available in Tungsten (3200K) and Daylight (5500K). Other color temps by special order
Package: Single unit, self contained. Battery module separates for charge/swap.

Full specs will be published soon and will be available in the underwater lighting section of our website.

Pricing and availability are TBD. We already have a list started (and growing quickly), so send us an email or Contact us for more info.

National Geographic's Migrations - Nov. 2010

Hey gents. Was recently emailed a link to National Geographics new show, "GREAT MIGRATIONS". I had the pleasure to work with a great group of folks on a few of those segments and of course much of it underwater. The series contains much more than what we were involved with, but for sake of underwater I'll list only the shows i had worked on that i know were shot on RED. If you go though the other shows and especially behind the scenes, you'll see a variety of cameras.

Of particular interest and underwater visuals is the Jellyfish Lake show. Shot entirely on RED underwater (80% topside). You'll notice some nice MOCO shots---compliments of Stewart Mayer of www.kickasscamera.com and www.camblock.com - this guy knows his trade and such a work-a-holic. While on the list of folks......
Jellyfish Lake Segment: Ken Corben, Adam Ravetch, Mark Thorpe, Stewart Mayer---our team in the field

Walrus Segment: Adam Ravetch on various locations then Adam and myself at St. Lawrence Island.

Looks great Johnny! Hey, did you receive an e-mail I sent you a while ago?
 
Will do Johnny, man, can't help but thinking of how majestic those jelly fish would look in 3D...
 
Really happy with my camera

Really happy with my camera

Every time I shoot with my RED camera underwater I continue to be happy that I'm shooting the RED One. I was just looking at some footage that I hadn't had the chance to work with in RED CineX, the vis wasn't that good that day but I worked with the R3D file a bit and then exported it as a Pro Res 4444 file and just am so happy with what I have, it's almost 3 dimensional on my HD monitor...if I had shot this with any other camera it wouldn't be what it is image wise. Very happy I purchased my camera.

Going to finally break down and pick up the RED Rocket this week, I'm certain this will be the best thing I could do instead of spending so much time in post production, sometimes painfully processing the files. Should have already bought one...

my 2 cents worth...just really enjoying my camera and the imaging that comes from it.
