Ok, I'm not entirely sure this qualifies but here goes... This is my first competition and only my 4th or 5th post so be gentle.

I've never actually done a refraction before yesterday I like the concept.

I'm going out on a little bit of a creative limb since the only thing I could find to refract through is a 2.5" acrylic juggling ball... and... well...

Basically I took a picture of a Matted/framed photo I took in the spring of 2006 (http://www.scottgunsti​lls.com/photos/3932697​69_WEDJV-S.jpg (external link))

Camera: Canon EOS 50D
Lens: Tamron 90mm Macro (at about ~1.5:1)
ISO: 125
Exposure: 1/250 sec at f/25
Flash: Canon 580EX

The reason the Image of the framed photo is right side up in lieu of upside down is because I hung it on the wall upside down... ;)

The original photograph was also taken using the Tamron 90mm... and I matted and framed it as a gift for my then girlfriend (and currently fiancee) as I really enjoy giving her flowers... :)

Alas... no, I've just spent too much time at another forum in conjunction with my other hobby of photographing people jumping out of planes... :oops::lol: and forgot about this one... I really want to remedy that though... :)

Awesome entries everybody!

Scott - very nice example and I think I need to find one of these juggling balls. For a while there I thought you were going to be the only entrant!

John - Way Cool!! Awesome display of how the thickness of the soap and the refractive index interact and as a plus you got an LSD based playground out of it!

BASmith - Just a perfect execution here - I love it.

Geno - Great job! Would like to see the subject a bit more in focus in some of the drops.

Daniel - Nice water drop shot -- I love the colors.

Richard - You should have left your image up. A very nice example of refraction and I thank you for sharing your set up - very nice.

Ok.... The Winner is BASmith - Congrats and I look forward to your Challenge.

Thanks again everybody -- awesome photos one and all!

Congrats BASmith!

Monty, thanks for the comments on mine and all the photos. It helps me immensely.

Still learning about this Macro stuff and working with such small DOF. I had to take the shot on an angle which made getting more drops in focus difficult. Maybe I should have cropped it smaller. :)
