slow motion close up droplett of rain?

This is probably the best place of any to ask this question and any help will be greatly appreciated.

Using my XL2, how would i go about filming a single drop of water fall then splash on to the ground, then be able to see the tiny splash that the droplett makes when it hits the floor. What conditions should i film in, what shutter speeds, iris etc etc. I just cant seem to get it right.

Is this asking too muh of the XL2?

Also is there a macro mode on the XL2?

Thanks,
Kyle.

Perhaps not asking tooooooooooo much. :-X ::)

The higher the shutter speed the more precise the capture of the image. The higher the shutter speed, the more light is going to be needed. The problem with the high shutter speeds is that your going to missing some of the action (staccato) as opposed to a camera that can shoot at faster frame rates.

The faster framerate is what will properly capture something like this (not 24 fps but more like 2000 fps.)

My 2 cents

I think you might be asking too much from the camera?

Asking way too much.  The closest you could get would be to record in 60i with a very fast shutter speed (maybe 1/250?), deinterlace into "60p" with whatever the best deinterlacer you can find is, and slow down 2X or 4X using the best frame/blending time-remapping thingy you can find (twixtor?). Then play this back at 24p.

It would look pretty awful like this, though and I doubt it would be worth the effort.  I'd do this in a 3d program, but even then it would look a little fake.  If you have 3dsmax I can describe to you how I'd do it if you want.  It would look pretty good--much better than if you recorded it with a DV camera--but would take forever to render (metaparticles and lots of ray tracing, I'm afraid.)

From a distance it could look pretty good with standard 3D, I think. Not much better than "acceptable," but infinitely better than DV. I'd expect the shot would have to be from a distance, since it would be hard to focus in on such a small object if it were shot with a camera anyhow.

In max, I'd render the drop with a lathe, then use the noise modifier on the soft selected bottom portion and key frame it extremely slowly so it looks like the bottom of the drop is being effected by air resistance. I'd then move the drop down with accelerated motion until it just touches the "ground" then turn its visibility to zero and swap it with a meta-particle system based around the shape and material (some basic raytraced water refraction) of the drop, with perhaps another particle system inside it to simulate the parts of the drop that aren't around the edge. Then put a deflector on the ground, use a gravity modifier, and mess around with friction and bounce settings.

If you have the budget for a good plug in or (even better) a slow motion camera, go for it, though. This is a pretty sloppy solution.

Trying to acheive something like this on DV is pretty hard if not almost impossible for it to look really good. I think your best bet is CG or if you can get your hands on a 20000fps camera then go for it. Ask Mr Land, if you can wash his car. Of course it doesn't hurt to try.

Thanks for all the great responces. I thought this kinda of shot would be beyond the XL2. Nevermind. I do have 3Ds max, but i dont have a clue how to use it, so i may have to simplyfy the shot.
Cheers,
Kyle.
