Water drop

Actually oil being dropped into water.

 

Real cool! ; I am on the bandwagon of "how did ya do it?"

 

Did I double post this?

For these shots there is a lot of trial and error tying to get the timing down. ; Unless you have some type of electronic photogate.

Dark room. ; I had my camera tethered to a laptop.

For the shot I put some cooking oil in a small water bottle and put a very small hole in the bottom and adjusted the cap to control the flow of oil. ; I just got some IV bags and tubing that was going to be thrown away, so this should give even better control over the drop(s).

Green poster board for the background.

Water in a glass filled to the top and put this in a pan to control the overflow.

Manual focus. ; I took a wooden paint stirrer and dirlled a hole in the middle then put a pencil through the hole. ; Then placed the stirrer on top of the glass so that the pencil was where the water drop was going to hit. ; Then focused where the pencil went through the stirrer. ; Any method would work as long as you are focused where the water drop hits.

Flash off cameral to my right and white reflector to my left. ; The flash was controlled using the wireless flash function of my 7D.

Some type of remote to trigger the camera. ; Or you could be in a room with no lights and trigger the flash while the camera was on bulb.

Shutter speed set to control background exposure and aperture set to control flash exposure. ; Make sure the depth of fied is such that the entire drop/splash is in focus.

Then, ; lots of practice. ; This shot took around 100 shots to get. ; After a while you get the timing down.

I am in the process of building a photogate trigger which will trigger the camera when the drop falls through the photogate. ; You can get these at HiViz.com fairly inexpensively. ; They have sound and photo trigger kits to build.

The oil in water was nice since it gave the smooth ring as opposed to wate in water which gives you a crown effect like the pic attached.

I have seen some spectacular shots with water drops colliding. ; Hopefully with the photogate I can get some.

 

Thanks for the info! ; Sounds like one needs a lot of patience for this! ; Like the yellow in that second one!

 

all that hard work payed off doc. pretty neat shots

 

Thanks everyone!
