Hello everyone,

I have been visiting and viewing here for a little while. Well, I finally decided to join in.

Started playing around last night after seeing similar shots on another forum. It was a little more difficult to time then I thought.

Anyways, CC are welcome.

Oh yeah, I used: 20D, sigma 150 macro, and sigma EF500 Super DG.

Blue water drops dropped in to red water.

Thanks for looking
Travis

    Great shot- well done- Never managed to catch a "crown" on a water drop shot.

    Hi there Travis........ what a lovely Crown, and I gotta say what a pretty colour it is too clap.gif very nicely executed indeed .....well done thumb.gif
    To get a crown what's the secret?
    Depth of fluid?
    Side of droplet?
    Thickness of Fluid?
    Hight?
    Care to share how you went about taking this shot ?? mwink.gif

    What a nice shotclap.gif
    I am really jealous... Question: What was your setup? What did you use for dripping?
    Cheers,

    Hey Travis, welcome to dgrin and to the water drop club. lol3.gif

    I'd have to take credit for being the local drop geek as it's what I do in my research (sometimes) as well. So I have some nice tools to take advantage of in my lab including syringes, fine pumps, and lots of good light.

    You're shot is great, timing is good, but I'll make one comment that I'm sure you've already noticed. DOF is a b-tch when you're that close. Some of the best crowns I've captured take a slightly different angle to maximize how much of the crown is in focus. Like so:

    Second comment: satellite drops. I kinda like the motion blur you have on yours but you'd be surprised at how relatively easy it is to stop them. Based on calculations, they are whipping along, but I'm always amazed at how fast our consumer grade flashes can strobe. If you reduce the power on the 580EX (or Sigma 500), you essentially speed up the time it's on, to something as fast as roughly 1/8000 of a second. That is more than enough to stop a satellite droplet.

    Thanks everyone for the encouraging comments. They are very much appreciated.

    And thanks DoctorIt for the suggestions. I will try reducig the flash power to see if that helps. Before reading that I tried h-sync at 1/400 and +2/3 FEC, but that made motion blur worse. I couldn't figure out why. Looks like it was the strobe time.

    I bought some acrylic paints this weekend to try doing something similar, but hopefully the paints will have better color interactions.

    As far as set-up goes: I had the 20D on tripod set at 1/200 @f/11 with flash. I had a clear glass saucer plate with maybe 3mm of red water (food coloring) on top of pink paper. I used one of our kids old medicine droppers to drop in the blue water from a height of about 18 inches.

    I used white paper behind to kind of bounce the flash.

    Next time I will take a picture of the set-up.

    No problem, and you got it - it's not so much about the h-sync shutterspeed, and more so about the shortest possible strobe time necessary to expose correctly but freeze action. Without digging up the exif on that example I posted, I'm quite sure the shutterspeed was only 1/250ish, but the flash was at 1/32 power, +/-0 FEC. To be honest, I was suprised after I took it and it froze the action so well.

    Looking forward to more!
