Very nicel! I'll definitely be using this, thanks,
January 25th, 2008 @ 11:07 am
nice one!
January 25th, 2008 @ 11:14 am
WOW WOW WOW!!! So Nice!
January 25th, 2008 @ 11:15 am
Another great tutorial, as usual!! Keep on the great work^^
January 25th, 2008 @ 11:16 am
I have wanted this type of effect for a long time and was hoping not to have to subject my camera to actual water. Thanks a bunch.
January 25th, 2008 @ 11:17 am
Small request for convenience sake. There was no link to the actual tutorial from the blog. I know you usually provide one from here, so I'm sure it was just an oversight. Great tutorial, though. Thanks!
January 25th, 2008 @ 11:23 am
Nice Andrew:) You have a habit of making tutorials that are so usefull!
January 25th, 2008 @ 11:29 am
LOL, very good tutorial, thnx Andrew ;)
January 25th, 2008 @ 11:31 am
btw I was watching the views on your tutorials, it's just amazing that over 100 000 people have viewed some of your tutorials:O Gonna send you a champagne bottle when the views on one of your tutorial reach 1 million:)
January 25th, 2008 @ 11:43 am
awesome :)

Is this a similar technique used by Ahran in his Weather Replacement in AE CS3: Part 2 ?
January 25th, 2008 @ 11:44 am
simple but effective!
Great work!
January 25th, 2008 @ 11:54 am
Yeah, this is like what Aharon did :) I recommend checking his podcast for more advanced tips too.
January 25th, 2008 @ 11:56 am
Poor Sam, He's running away from home. What did you do to him Andrew??

Well at least he is still loking hot d;)

Watch this:
January 25th, 2008 @ 1:13 pm
just an fyi: Cool tutorial, but don't forget that images coming through a water droplet are always upside down and mirrored. Thats easy to do with this technique, but you forgot to do it in the tutorial ;).

Wow! Never thought about using this to create a sad mood. Thank you for that short - but still useful - tutorial. Also thanks to Sean Emer for his tip on mirroring the footage.
What's about that Cold Breath Tutorial? Are you still going to do it?
January 25th, 2008 @ 6:35 pm
Nice effect, I see plent of usefull ways with this =)

Thumbs up for kramer !

January 26th, 2008 @ 9:10 am
i know this technique from aharon rabinowitz, but i will watch yours right now
Was your own idea? or did u just copy it from aharon?
For me doesnt really matter, all of your tutorials are great and everyone explain it in different ways. for example: aharon explain all of the tec site and maths and so on and ak explain it easy to understand. Thx for all tuts! ;-)
January 26th, 2008 @ 10:18 am
any ideas on how to make the water beads streak as they fall down the lens?
Garrett Gibbons
January 26th, 2008 @ 10:36 am
So we've seen Sam in some pretty depressing situations lately. Is this part of some larger project, or is life just sad for you guys lately?
January 26th, 2008 @ 11:58 am
Great tutorial!

@ Pat Norman: I created water beading streaks. I think thats what you wanted to ask for. Just look on my Youtube Channel. I'm uploading the vid at the moment.

January 27th, 2008 @ 3:04 am
hello everybody !

thx for the the tuto andrew, here's my work :

i'll try to make the effect more realist but i must find how to make the image in the droplet mirrored.

January 27th, 2008 @ 3:40 am
Nico: can't you just flip it?

Great tutorial Andrew. I'm really looking forward to that bridge collapsing tutorial. Hope to see it soon.
January 27th, 2008 @ 3:58 am
To Mirror the image just rotate it 180°. Then you will have the problem, that the raindrops are coming from the ground flopping upwards. This can be fixed by changing the Mr. Mercury effect's gravitation to a negative number like "-0.15".
I tried it but found that it looks a bit strange, don't know why...
Yesterday I made a test for creating streaks behind the raindrops. The video is very short but I think if you watch it twice you will get an idea^^... here's the link:
January 27th, 2008 @ 7:52 am
nico: just apply the Flip + Flop effect to the mercury layer. Here is a rough example.

January 27th, 2008 @ 8:16 am
Awesome! Check out what idid with this effect!
January 27th, 2008 @ 8:23 am
@Sean Emer : Thank you for the tips !! you're cool !!
January 27th, 2008 @ 11:12 am
re hello everybody, here's the final version of my work

sorry for the quality of my video but youtube kill the quality :((
January 27th, 2008 @ 11:32 am
Looks great! I would have used caustics for this kind of effects. But this is perhaps the better method.

January 27th, 2008 @ 2:51 pm
nice one, i have done something pretty similar before

i made rain with a simple particle system but this really helped me fine tune the water on the lens part of things. thanks for another great one :)
January 27th, 2008 @ 3:16 pm
hey i liked this tutorial but if i can make a suggestion, you should try making a tutorial on the effects used in the movie Jumper. id really like to know how to do that.
January 27th, 2008 @ 3:41 pm
Great Effect
January 27th, 2008 @ 6:00 pm
Hey folks- I tried posing this when the tutorial came out but it did not go through for some reason.

I have to give credit where it's due - a good few months back when I told Andrew about my idea for the weather tutorial, he suggested I might be able to improve the look by adding raindrops to the camera lens, using Mr Mercury. We didn't really talk about how to do it, but he planted the seed for the effect.

So, While the implementation was mine, the idea to even have rain drops on the camera only came about because Andrew suggested it. I would not have thought of it on my own, and I probably would not have thought of Mr. Mercury for it.

I recorded the tutorial about 2-3 months later, and forgot to mention it - that's unlike me, and I apologize.

So, kudos to Andrew on the idea - it was a great one.

. they look waaaaaay to circular and nice and just generic ..

January 27th, 2008 @ 11:02 pm
I disagree lifetype,
And not only that This Tutorial is a stepping Stone for your own
Yes this may not be for Broadcast Specifications but...
No this is fine for Broadcast in fact this effect alone is awesome
And I bet we will be seeing more and more of it now that Aharon & Andrew
Have made it obvious to the rest of us!

Thanks Aharon & Andrew
January 28th, 2008 @ 1:23 am
NICE =) !!!!!

January 28th, 2008 @ 11:49 am
@ Jim Andrews: Yep, I recently saw a commercial on a major network that used at least 4 tutorials along with a good portion of the Riot Gear collection. Of course I don't know what they were advertising because I was too busy recognizing all the tutorials and graphics, hehe.

You can't just flip the video that the effect is on... The image going through each drop should be flipped individually, not the entire image. That would mean Sam would still be on the right, but upside down, instead of being upside down on the left. I don't know how to do that, but doing it like Andrew is a lot more natural-looking than the flip.
Dale Jackson
January 28th, 2008 @ 12:53 pm
WOW!! I have to say your tutorials, Andrew, are the best of the best! Any chance of doing a realistic tornado tutorial, that would go well with this raindrop one. Excellent!
January 28th, 2008 @ 12:54 pm

I was just wondering... who would win an `after effects` off battle between Aharon V Andrew....

Tough one to call, both had good teaching manners and deliver a very good tute....
It may come down to how many bad joke they could cram in a tute... in which case The K man would win...

January 28th, 2008 @ 6:53 pm
Charles: Technically you're right, yes, but I haven't figured out how to do that flip. Still, at least turning the footage upside down is a must or else you lose the realism of the effect because having an upright image through raindrops on the camera lens is physically impossible.

Each raindrop technically should have a 'wideangle' view of the entire video area upside down and mirrored, but that would probably require doing it a different way than Mr. Mercury, so if you're going to use Mr. Mercury I would suggest at least flipping the image upside down. You'll get closer to looking realistic, as the mirrored nature of the image is less noticeable than the inverted nature of the image. Am I making sense?
January 28th, 2008 @ 7:31 pm
Hey I saw a riot gear produced promo today as I was riding the train. I flipped out, good job as always sir.
January 28th, 2008 @ 10:29 pm
To Aharon Rabinowitz:

Actually, you did comment buddy. Only this is the blog you are now commenting in. The other comment you left was on his tutorial, not his blog. if you click on 'tutorials' then the rain drop tutorial, you should be able to get to your other comment.

And hey, dont worry about it, it confused me too.. lol.

P.S. Loved your weather replacement tutorial :D I wish to see more super cool things like that from you in the future ^^
January 29th, 2008 @ 3:49 am
I did one video, and i got some real drops on lens, check it out
Charles Bronson
January 29th, 2008 @ 9:35 am
Sean: I'd agree, but only under certain circumstances. If there is a bright light on one side of the screen, I think it would look much better to be right side up and on the correct side of the screen than upside down on the wrong side. Like, if it was a shot of a road, i think it would be distracting to see the yellow lines up in the sky and gray clouds in the street.

In the example you posted, there are lighter wood colors on the outside and darker colors in the middle, so it's symmetrical enough to work. Both ways are technically wrong, but I guess you just have to decide which is best on a case-by-case basis.

Does anyone know if you can use Panopticum Lens Pro for this?
I imagine it would look pretty convincing, but I don't have it, so I don't know about animating it or anything.
January 29th, 2008 @ 10:12 am
Charles, I got your point and I see that I didn't explain myself in the last comment clearly enough. I agree that the horizontal mirroring would be technically wrong, but a vertical mirror would make it much more realistic. Sam and pals would still be appearing on the correct side of the screen, but the illusion of reality would be maintained by the vertical flip. In essence, flip it vertically, but not horizontally. Its 50% closer to being real, but even more so visually since the vertical flip is the most noticeable.

Having the drops as they are without any flipping or flopping is physically impossible (though pretty) and will instantly draw attention to itself if used to try to pass off real rain.
January 29th, 2008 @ 11:05 am
hello everybody,

the optic of the water droplet is not easy to make there are many thing like refractive index and other forces of the nature .... like the lightning bolt. it's necessary to have a good documention before trying the effects.

in after effects i like making lightning and it's no easy to do, before making an effect i read some articles on the net ( like wikipedia ) to have a maximum of documentation.

but i'm not physician :)
January 29th, 2008 @ 1:07 pm
i need you opinion, sometimes when we look a water droplet, the light refract like rainbow. i decided to make this effect.

here's two pics the first is without the refract effect and the second with the effect. i would like have you opinion about this. thanks.

special thanks to sean and charles for your tips.

first :

second :

Charles Bronson
January 29th, 2008 @ 1:31 pm
well, what we're talking about is this:

anything past that focus point would appear to be upside down, and drops are so curved that it's always flipped.

Sean, I see what you're saying now, even though you'd still have some road in the sky and clouds in the road that way. i guess leaving them unflipped would work best if you were to leave the drops out of focus the whole time, but flipping it would be important when you do focus on them...
January 29th, 2008 @ 8:01 pm
Hey charles, I'm assuming that the convex lens in your example is representative of a water droplet on the lens. The "focal length" o the water droplet would be incredibly small (thus the 'wideangle' look you get through them), so everything would be flipped if it was on the lens shield of the camera.

Having the sky in the road and the road in the sky will look realist ONLY IF you see the edge of the road or the sky meeting each other in the droplets. If not, then I agree with what you said. Otherwise, the inversion adds to the realism. Try sprinkling some water onto your window and then look at them. The inversion of the image makes it seem very real.
Charles Bronson
January 30th, 2008 @ 1:33 pm
Actually, it was raining yesterday, so i looked out my window, and it looked almost nothing like this effect, inverted or not. at least when it was out of focus. There are all kinds of geometric shapes made by the light that i have no idea how to fake.

I think we're pretty much in agreement at this point anyway.

nico, are you talking about chromatic aberration? your second picture looked good, even though the effect was exaggerated. how'd you make that, anyway?
January 30th, 2008 @ 4:47 pm

This raindrop tutorial helped me out so much!!! Because of Andrew's tutorial here on the use of CC Mr. Mercury, and Video Copilot's Real Clouds I was able to actually, and finally, produce a very realistic tornado scene, all in AE, only with AE, Real Clouds, CC. Mercury and some actual tornado sounds. Thanks so much! I'd love to show everyone how I did it.
Dale Jackson
February 5th, 2008 @ 2:38 pm
Andrew, I wanted to show people your water drops in effect with a tornado. All using Video Copilot Real Clouds and this tutorial. Again thanks! Great work guys!!
February 6th, 2008 @ 7:26 am
looks great like always
February 8th, 2008 @ 12:05 pm
@mike: that's what i was after, a little distortion of the drops. how'd you implement it? looked nice.
November 28th, 2010 @ 4:09 pm
That's an interesting look.
