Underwater reflections.

[Sharp]

Sometimes we can see reflections under water. In this picture airpocket have made mirrow to the sealing of the cave where you can see a part of my buddy Tommi.

That is so kool. who else has something like this?

[Andrew]

Now that is amazing! Was it planned or by accident when reviewing the pics later? Well done anyway

Thank you for you comment Shooter and Andrew.

It was planned before the dive. There is couble places in that cave/mine where I can try to take those reflections.

Here is another feflection of my buddy Jani from same place. It is easier to shoot CCR diver, because he dont break the mirrow on the roof with bubbles.;)

Here's a reflection shot of my wife (Sharon) snorkeling at 3 Sisters spring near Crystal River, FL. Lots of weird stuff going on! (I may have previously posted this shot somewhere else, but I can't remember where)-Clayhttp://claycoleman.tripod.com/b7abdd50.jpg

Sharp: those are really cool photos!

I took a few shots after my basic cave class in Florida a couple of years ago; you can see reflections in these two. I was shooting with my old Olympus C-4000, with the onboard flash and no wide angle lens, hence the low quality:

Here's a bit of reflection above one of my buddies as he's swimming out of Little River:

And here's a close-up of the bubbles on the cave ceiling reflecting my light. They look like pools of mercury.

Nice pictures scubagirl.

The walls of caves in Florida seems to be quite dark comparing the caves in Mexico. Is there in Florida any stalectites and stalecmites in caves?

[scubagirl]

Thanks!

I'm not a cave expert, but no, the Florida caves were never dry caves, so they have no stalagmites/stalagtites. They are all dissolution caves, some of which have very high flow rates. Some of the caves are lighter-coloured because the dark parts have been rubbed off by diver traffic (high traffic areas like the Devil's system at Ginnie Springs), though the further inside you go, the darker the surfaces get. The Florida caves have some interesting formations, but they are not quite as decorative as the Mexican caves.

I've dove in the cenotes in Mexico, and I hope to go there to finish my cave course someday; those caves are very decorative and photogenic :)

Wow, how there can be reflection because there is no roof (cave or ice) above her?:eek:

That is magic Clay!:D

Just a quess, but wouldn't this be the result of refraction?

Both reflection and refraction are going on. The mirror images are, indeed, reflections from the surface of the water (ever shined a light at an angle toward the surface at night? You can see the beam reflecting back down.) The bending of the snorkel at the surface and other distortions are caused by refraction. A displaced image of the snorkel above the waterline is also caused by refraction. The "joined at the head" reflection and the disembodied hand are kind of creepy. -Clay

Thanks Clay for the clarification. The photo would be an ideal example of those properties in a presentation.

When light travels between two different media (meaning: they have a different index of refraction), some of the light is reflected, and some is refracted. So you are seeing both in Clay's pic. The trees and stuff above water are being refracted, and Sharon's reflection is also visible in the surface.

Oh....Clay beat me to it. I didn't notice the second page! :)

Here is three pictures of reflection. First one is color picture where the color of water is real green.

Next one is made blue with Lightroom.

Last one is made black and white. Some how I personaly like the black and white one.

I like the first best. Like the green water.

That green color is original/natural color.

[Jonathan Bird]

I like the green best too.
