I use a 2kg weight belt, dive down to the bottom then swim up to the subject. The lights have a tendency to scare the fish, but I can usually get them used to the light when I use scuba and can go much slower than when I snorkel.
I think you are underselling your SeaDragons. They are 2000 lumens each so you dive with 4000, not 2400

They look pretty good units, 2000 lumens, 5700k, 100 degrees beam & $399 each.

I was looking at a video light when I bought my housing, but in that price range in the local stored, the colour temp was always way out. As I would want it to complement my dive strobe, I want the video lights to match and be 5700k. Ikelite makes a similar unit, but more expensive, similar power but only 65 degrees beam. So I did not bother. If they were selling SeaDragons I suspect I might have bought a unit

The SD 2100 dual beam looks perfect as it looks like it can double as a video light and a focus light

Re: Underwater Photography

You're correct about the Seadragons, 2000 lumens each 4000 total.

I purchased mine at Cameta.com (Cameta camera). Buy lots of light, it doesn't go very far down there, get 10 times as much as you'd normally use above water.

Lighting makes a huge difference. Without the light, "The Blob" looked like a beige rock.

Why the red filter? I though they were only needed to correct blue or green water which was only a natural light issue? I bought both filters for my gopro but never really tried them.

I keep meaning to add a gopro mount on my dive housing to see how it goes.

That's cool!

I see a horse!

In the middle it looks like a sculpted (petroglyph or bas relief) horse in profile!

Or…a scorpion with stinger at upper left!

Seeing this, and not knowing it was a sponge, someone might suspect an ancient civilization carved it and was submerged (e.g. Atlantis).

Or…just maybe I have spent too much time around Horses and Scorpions in the last few years here in the American West.

It is a very nice and colorful sponge. Thanks for sharing the photos here.

Also confusingly, Wikipedia states it as being both "commonly found in the Mediterranean Sea, Aegean Sea and Adriatic Sea" and an "endangered species" .

It apparently doesn't have a vicious sting, but I wasn't about to check this out . The image was just darkened a little and cropped:

Following Steady's request, edited to add:
This was taken in the Sporades, NW Aegean Sea, Greece, 30th July 2015

Hi SWL!

Thanks for adding the location.

And that is a BEAUTIFUL Medusa!

I have always been fascinated by jellyfish and the many forms and sizes and WILD looking shapes and colors in which they can be found.

This one is really pretty (to me). Love those little round/dot darker shapes below. Very nice.

Re: Underwater Photography

SWL.

You posted a nice and interesting photo of the Octopus's Garden.

I suspect the smart Octopus brings things those shells there in order to create an inviting spot for a fish to investigate for food or shelter. Then when the fish looks at the shells (or hole in the middle) as "shelter" from bigger fish….WHAM he is in for a big surprise when the hiding Octopus grabs the little fish!

And, that is where the term "sucker" came from (tentacle suckers). Of course, this is just my own yarn, but I think it rings true and will use it on any unsuspecting…suckers…er...lubbers.

The red filter gets rid of the excessive green tones. Even more noticeable further down. Your eyes and brain color correct to some degree, but the camera just sees green and blue down there. Just leave the red filter on all the time, it can't hurt and seems to help most images.

For my anchor shots I use my anchor as the "neutral grey" for the WB picker in Lightroom for my colour corrections. When not shooting anchors I'm screwed

Re: Underwater Photography




The camera doesn't really capture the markings, which are much more vivid than this.

Re: Underwater Photography

I still get a kick out the look on this puffer fish's face, sharing a hidey hole with a queen angel fish.
