The Pareidolia Thread

One of my hobbies is hi-speed micro photography. I have photographed hundreds of water drops as they fall into still water then rebound as a column of water with a perfect sphere at the top. Occasionally, for various reasons, the rebounding water column will be disturbed and form random shapes. More often than not, I see a distinct recognizable shape in the water which is sometimes uncanny.

I thought it might be interesting to see what others see in these random drop images.

Drop #1
What I see:

Ah, the power of suggestion.

I did not see anything in the drop until I read the spoiler and now I cannot help but see it.

It's not "supposed" to be anything but what it is: a water drop splash.

Let's move on to image #2.

DROP #2
I swear that this water drop image is straight from the camera with no post processing or manipulation of any kind. The lighting I used gives it the metallic
appearance.

Probably too thick.

There was an episode of the show Time Warp (IIRC) where they were filming water drops. They had a rapid drip so that the falling drop would hit the upward jet of the previous drop. It caused a flat disc to form at the top of the jet.

Here it is. Check out his two-color lighting setup.

I use water, milk, alcohol and other liquids. Food dye is added often as well as various surfectants to change the surface tension.

Here's a shot of a water drop I blasted with a .22 calibre pellet gun. The timing on this took a bit of engineering.

I've shot hundreds of 2 drop collisions. The timing is critical!

Photographing a 2 drop collision while holding the dish in my hand required steely-eyed yogic concentration!

Very cool. Could you control the direction of the splash by placement in that dish?

Yes. I experimented quite a bit and found that the parabolic shape of the dish would focus the drop energy at an angle if the drop was placed off center.

My goal was to cause the rebound column to rise at a slight angle and then release another drop to collide with the column off-center. The result was that I am now able to tilt the resulting splash ring from the collision at any angle I wish, within limits, of course.

The purpose of the experiment was to use the tilted splash ring as a target and shoot a .22 caliber pellet through the ring.

The splash ring, tilted at a 60 degree angle, was oriented to be a target facing the camera which was mounted above the gun barrel.

It took quite a while to engineer the set-up with 2 intervolometers, a drop valve solenoid, gun trigger solenoid, a 24v DC relay, and strobe sequencer.
All the component parts had to be timed to react precisely to capture an event that lasts a couple milliseconds.

Here are a couple of images from the experiment. The viewers POV is from above the gun barrel with the pellet traveling 450fps away from you.

-
Experimental shot with column tilted too much - second drop (on left) barely missing the column The drop on top is the sphere of water that normally separates from a drop column as the column falls back. POV is 90 degrees to gun on this shot


-
Successful drop with collision splash tilted at 60 degrees toward camera+gun POV from above gun barrel


-
Pellet leaving gun at 450fps as collision splash ring is expending POV from above gun barrel


BULLSEYE! POV above gun barrel


Crop of above shot

I don't know about anyone else, but I would love to see fishbait do something with fire. Say, take pics of water dropping with flame reflections in them. Or perhaps drops of lighter fluid, ignited, falling into a small puddle of gasoline or something interesting.

*please*

Sure, no problem.

I'll need an assistant to light the fire while I handle the camera with my 500mm super telephoto lens from a few hundred yards away. The job is yours if you want it.

BTW, what's with this?

Jeez Loueeze! Do you have any idea how difficult this stuff is? I challenge you to find any other images of double water drop collisions being shot with a gun on the internet. Or even single drops! Now you want flaming gasoline drops!

Thanks, Mr. B.

If you are interested, I have a thread on the NikonCafe forum that is 60 pages of images and detailed descriptions of all my experiments.

I'm currently experimenting with cryogenically freezing stuff with liquid nitrogen to -321F and then blasting with a gun.

The thread can be found HERE.

-

Here's a falling water drop being shot. Extremely difficult to capture.

ETA: Cool pictures though.
ETA2: Perhaps the thread should be split into one for the pareidolic pics and one for the cool time-stop pics?
ETA3: No idea how one would accomplish such, but having dropping liquid of one color/viscosity/density into another could be interesting

On the subject of photgraphing things on fire, you can get some quite interesting 'molten drops of fire' from burning / melting a dust bin liner....nb I recommend you hold it on the end of a stick or similar!
