I get the concept, but wanna see some images.

Anybody got any???

These two new challenges do nothing for me. :(

Any of the myriad "upside down water drop" shots we see so often are prime examples of refraction. Shots with prisms or CDs breaking light into its components are refraction. Backlit oil-in-water shots, soap-bubble or oil-drop shots, these are also refraction. Gonna be interesting to see where this goes.

Setzler's famous flag shot is perhaps the best-known refraction shot on DPC:

SOme examples of refraction. Remember that it's when light passes through one transparent medium to another, it changes speed, and bends. How much this happens depends on the refractive index of the mediums and the angle between the light ray and the line perpendicular (normal) to the surface separating the two mediums (medium/medium interface).

As Bear says, this will be a fun challenge and see how people interpret the description. ;)

:P....I'm not sure if I'm entering this one yet, depends on if I can get some good shots

I have a couple of ideas for toys two....so we'll just have to see.

Man, they gave us some pretty crappy challenges for the MS Tournament eh?

I'm looking ofrward to competing with you in the first round...good luck!

For some reason I read it as Reflection. lol. Ok this is more interesting...

I'll take a deep breath and think about this one... I am stumbling over toys all the time, so nothing nice comes to mind when someone mentions toys. The thing is, it may be that both challenges will have 300+ entries... not "hard" enough.

In the end, it's all fun for the good cause. Good luck to you too!

WAIT!

I just came up with a brilliant idea for "Toys"! Oh yes...this is going to rock if I can do it right. Hmmmm....need to go to Wal-Mart tommorow....yes, yes, yes.

LOL Can you say that again in English!!

Just use a bad lens. Chromatic aberration is a result of refraction.

Come to think of it any photograph is a result of refraction, so it's an open challenge !

So it's, ummm, the "Rikki Blue and Orange Challenge"??

also a kind of refraction i guess
03/29/2006 08:15:53 AM · #17
Ok, I get it!!! But whether I can pull one off is another subject completely.

Toys?? Hmmm - I predict tons of rubber ducks and Barbies.

Will there be oodles of people who have no idea what refraction is?
I'm not trying to be mean, just wondering.
Not everybody reads forums threads and not everybody bothers to google and learn, either *sigh*.
03/29/2006 11:17:39 AM · #23
I dunno about other people but I learned what refraction was when I was about 8, so hopefully most people will 'get it' :)

I guess that is what I worry about. They might vaguely remember the prism from Grade 3, and vote everything down that doesn't have a rainbow coming out the other side.

I wonder if people would be physics-literate enough to declare this kind of shots DNMC (diffraction is not refraction)? :)
