A place to share interesting photographs and pictures. Feel free to post your own, but please read the rules first (see below), and note that we are not a catch-all for general images (of screenshots, comics, etc.)

Spoiler code

Please mark spoilers like this:

Hover over to read.

Rules

  1. No screenshots, or pictures with added or superimposed text. This includes image macros, comics, info-graphics and most diagrams. Text (e.g. a URL) serving to credit the original author is exempt.

  2. No gore or porn. NSFW content must be tagged.

  3. No personal information. This includes anything hosted on Facebook's servers, as they can be traced to the original account holder. Stalking & harassment will not be tolerated.

  4. No solicitation of votes (including "cake day" posts), posts with their sole purpose being to communicate with another redditor, or [FIXED] posts. DAE posts go in /r/DoesAnybodyElse. "Fixed" posts should be added as a comment to the original image.

  5. Submissions must link directly to a specific image file or to an image hosting website with minimal ads. We do not allow blog hosting of images ("blogspam"), but links to albums on image hosting websites are okay. URL shorteners are prohibited.

  • If your submission appears to be filtered but definitely meets the above rules, please send us a message with a link to the comments section of your post (not a direct link to the image). Don't delete it as that just makes the filter hate you!

  • If you come across any rule violations, please report the submission or message the mods and one of us will remove it!

Please also try to come up with original post titles. Submissions that use certain clichés/memes will be automatically tagged with a warning.

The coolest thing about that is that after the teeniest droplet is gone, you can see the shadow of an even smaller one started to drop.

[–]Batmaners 2 points3 points ago

I was disappointed they stopped the video short of the last one.

[–]ThePendulum 0 points1 point ago

So why is that last one different from the other drops? All of them have a shadow...

Very cool none the less.

[–]idontremembernames 0 points1 point ago

It's not, physically. it's just too small to see so the people that made the video thought the process was done when in fact it wasn't. We can see it, though, because of the shadow/reflection it casts on the surface.

[–]ThePendulum 0 points1 point ago

The drop itself can be seen as well, not just the reflection of it.

[–]idontremembernames 0 points1 point ago

I stand corrected. I just can't see it then =P

[–]jewzeejew 0 points1 point ago

You can't see the drop, you can only see the shadow.

[–]ThePendulum 0 points1 point ago

Look closer... you can clearly see it reach its highest point.

[–]jewzeejew 0 points1 point ago

oh hey! You're right.

[–]Mitochondrius -2 points-1 points ago

Came here to check if anyone already mentioned this. Was not disappointed.

[–]ogmilk 42 points43 points ago

Step one to getting KARMA

  1. Browse /r/videos

  2. Find a cool video

  3. Make a gif out of it

[–]GodEmperor 7 points8 points ago

4) Add "wait for it" to the title

[–]platinumpixel 0 points1 point ago

Wait, you mean I can take the top videos from /r/videos and get karma on /r/pics using this wizardry you call a "gif"?

tl;dr OP is a karma whore

[–]helpfuldan -1 points0 points ago

  1. use these cameras for porn.

[–]porksmash 97 points98 points ago

This is the worst use of the GIF format in all history.

[–]rmehranfar 62 points63 points ago

Why link a low quality version when there's an HD version?

[–]x-skeww 17 points18 points ago

[This 10,000 fps camera] can capture images 400 times faster than the human eye.

The human eye does not capture images at 25fps.

Our eyes don't capture images at all. The rods and cones are asynchronously polled and the new image information is "sprayed over" the old one.

[–][deleted] -3 points-2 points ago

There's a theoretical fps our eyes can see though. But yeah it's much much higher than 25fps.

For 3D movies, we see more than 120 images a second, so it's probably even higher than that.

[–]VulcanXP 3 points4 points ago

O.o wut? A 3D movie in a theater is still 24 fps. A 3D screen that uses active-shutter glasses operates at 120Hz, but that's so it can give 60fps to each eye.

That said, many people say they see a huge difference between a 60Hz and 120Hz (regular, not 3D).

[–]guywhoishere 2 points3 points ago

The difference between 60hz and 120hz is not that the images are changing at 60hz vs 120hz it's that it's refreshes at that rate. And the reason you can see a difference is that 24fps (standard film speed) doesn't divide into 60hz so you get frames of different lengths (half of which are 50% longer) which is visible. TV signals are 30fps (actually 29.97) in North America so 60hz works well for TV.

[–][deleted] 0 points1 point ago

Yeah the movies are 24fps, but the images changes 120 times a second to create a seamless 3D effect.

[–]_danada 4 points5 points ago

but the images changes 120 times a second to create a seamless 3D effect

This is only true for, like VulcanXP mentioned, screens that require active-shutter glasses that try to achieve 60fps . Screens that require polarized glasses (RealD [any 3D movie not in imax]) will project two images, both at 24fps, but through opposing filters that polarize the light. The each lens of the glasses filter out one of the images, leaving your eyes with two distinct images, creating opportunity for 3D effects.

[–][deleted] 2 points3 points ago

TIL!

[–]omnilynx 0 points1 point ago

That should be easy enough to test. Show a bunch of people a 60Hz scene and a 120Hz scene and ask them which is which.

[–]GTUD -1 points0 points ago

No, it's actually right around 25 fps.

[–][deleted] -1 points0 points ago

No, it isn't.

[–]Intrinsic_Value 2 points3 points ago

Well done.

[–]brokenseeker 0 points1 point ago

But how does it look in reverse?

[–]tanjoodo 0 points1 point ago

Because data caps.

[–]QuantoQuandoQuatro 0 points1 point ago

Seriously....fucking internet hipsters and their gifs....

[–]mjolnir616 4 points5 points ago

This is entirely not handy.

[–]jwoffor2 8 points9 points ago

I did not expect for the droplet to make 3 more droplets.

[–]xBaddie 3 points4 points ago

4* if you look closely you can see the reflection of the 4th one that's very tiny.

[–]ThePendulum 1 point2 points ago

You can see the droplet itself as well, quite clearly actually.

[–]jwoffor2 0 points1 point ago

You're right. I don't know why I didn't mention that one.

[–]Their_Police 4 points5 points ago

Dat surface tension. I think. I'm not a physicist leave me alone.

[–]Mr_Quail 1 point2 points ago

SPOILERS DUDE!

[–]katobleepus 0 points1 point ago

It's actually 4 in this one. Watch the reflection and you'll see the last one. They've apparently seen up to seven.

[–]T0tai -1 points0 points ago

I am wondering if it actually makes infinite droplets, each one being smaller than rest, a never ending cycle. But probably not.

[–]Fishyish 1 point2 points ago

At some point the molecules would not fit at the very least

[–]DontCallMeNeilSedaka 0 points1 point ago

Inside-out molecules. Sounds about right.

[–]silent_p 0 points1 point ago

Water is just a bunch of single water molecules all coalescing with each other like that, infinitely.

[–]zuma93 1 point2 points ago

It does not.

[–]haikukaburra 2 points3 points ago

dude posts huge ass gif
big gif makes firefox crash
gif is not handy

[–]Amazing_Retardo 5 points6 points ago

You broke reddit.

[–]Lasallexc 2 points3 points ago

I hate when my Sivu ei vaastas.

[–]Amazing_Retardo 1 point2 points ago

Did you know that in times before printing press some book copiers were illiterate because you don't need to know how to write to copy letters. Long story short it's "vastaa" :P

[–]ggabriele3 1 point2 points ago

What's amazing to me is that there are still parts of the process that are too fast. I'd like to see it at 100k FPS

[–]blubase 1 point2 points ago

it took longer to load than the video

[–]OGgarfield 1 point2 points ago

for those with 100 kbs download speeds this video was not worth the wait

[–]gaywalrus 0 points1 point ago

Ooh yeah, dat H-bonding

[–]RichiH 0 points1 point ago

you cut off too early (look for the shadow).

[–]BadBowtie1983 0 points1 point ago

I just want to say that this shit is cool.

[–]carpediem295 0 points1 point ago

I'd like the last mini drop to also be mega framed

[–]Hailene 0 points1 point ago

dat water tension...

[–]HaveSexWithMe 0 points1 point ago

Aaaand it's gone.

[–]cynix 0 points1 point ago

Now where can I get one of these cameras at a reasonable price?

[–]jameswasnthere 0 points1 point ago

I watched this while listening to Radiohead's No Surprises. Let's just say, I enjoyed it an awful lot.

[–]gripmastah 0 points1 point ago

Dat surface tension

[–]n1nj4_v5_p1r4t3 0 points1 point ago

if the needle was lower reducing the initial drops impact, how would that affect the cascade? The first drop appeared to be more of a collision then the surface tension giving.

[–]abravefight 0 points1 point ago

handy gif, 15mb, video.

[–]hollymo93 0 points1 point ago

Didn't we learn our lesson with the Mean Girls gif?

[–]DaveAlt19 0 points1 point ago

I refuse to watch it. It crashed my browser before I even managed to scroll down to it in RES. 15MB gifs should not exist, just save it as a video.

[–]acdcpeon 0 points1 point ago

Same here bro. Made my Chrome crap out. There should be a rule about files this large when using RES.

[–]DaveAlt19 0 points1 point ago

You can filter out items by keywords, it would be nice if you could set a file size filter, too.

[–]I_SHIT_PERIOD_BLOOD 1 point2 points ago

Remember in school when they told you Saturn has such a low density that if you found a large enough pool it would float ... I feel it would look like this.

Also, who the fuck would downvote this? It's beautiful.

Edit: when I commented this was at -2 ... so fuck y'all.

[–]yomamma9027 -3 points-2 points ago

Whenever I see "_____ FPS" I think of "_____ FAPS" so I'm thinking "wow.... 10,000 faps. horny bastard."

[–]Oelund -3 points-2 points ago

This is definitely not 10,000fps. Looks like 2000fps at most.

[–]writesomethingwitty 0 points1 point ago

See this link.

[–]Oelund 2 points3 points ago

Here is a similar setup recorded at 2000fps. Looks nearly identical to the other video.

As for the video in the link you provided: Seeing as they alter the framerate during some of the clips, for example in the first highspeed shot you see of the two bouncing droplets, it starts of "fast" and then slows down while the droplets are in midair. My guess is that they are not showing all the sequences at full speed.

Edit: Just adding the math: the drop falls for 12 frames in the .gif. Assuming it starts with a velocity of 0 and accelerates with 9.8m/s/s, within those 12 frames, the drop would only fall 0.7mm if it was recorded at 10,000fps. While it is hard to estimate the scale of the setup, I'm guessing that the drop has fallen about 1cm.

Edit 2: Just for the heck of it I did a similar experiment. Here is a drop of milk falling into a glass of water from about 7cm. It is recorded at 1000fps with my Casio EX-ZR200.
