| Could be that Langdon had this in mind when he came up with this challenge ... |

| hahahah cool idea Scav, I can see a sandwich shot with a 9mm, kinda cool if they can get it in slow motion! |

Jeeeeeeeez. . .what I'm wondering is if this will be the first challenge with not enough entries to dole out 3-ribbons.
Hmmmm: Note to self: Figure out how in the WORLD to take a photo related to the periodic table!

Some cameras have built-in intervalometers. What better way to take periodic images? |

Yeah, I have that, but I don't see any special rule allowing multiple (different) images ... :-( |

I think you are worrying too much. Here is the description:
"Take an interesting, creative photo of one of the elements of the periodic table."
Off the top of my head and probably in your home already:
Gold Jewelry
Silver Jewelty
Aluminum Siding
Copper Pipes
Oxygen (can you photograph something invisable)
It says to use one of the elelments. Any thoughts on the DMC flame wars that will occur on the Water (H20) and Salt (NaCl) shots which actually are made up of two elements?

Well, those are clearly compounds according to the PT, though water is one of the "classical" elements (and has been used as such in a challenge), so anyone who considers those DNMC would have a pretty good case.
Of course, if you want to get technical, people will also probably complain about gold which isn't 24-karat, and all kinds of other things which are not-quite-pure. The description would be better (IMO) if it said to take an "image representative or suggestive of one (or more) of the elements of the periodic table." |

Then it's just a freestudy, though I see your point. There's probably not going to be many pure, single elements. But as long as one element is the MAIN subject, I'm good with it, such as your gold example. I recognise they mean gold, even if they couldn't get it in its pure form.
edit to clarify.

It's quite simple, Sandy, have a look here:

I've got a hundred ideas already! This should be fun :)

I'm not saying people should complain about those things -- just guessing a few people will. I expect most people will take your pragmatic approach and consider gold jewelry or coins as meeting the definition of "gold -- the element" without requiring an assayist's certificate. |

Lol, General, you KNOW some will complain. It just wouldn't be DPC if they didn't! ;)
Hell, I even got a DNMC on a portfolio shot! |

Gold and silver will be common, as well as some certain forms of carbon as well, I would think. But there are lots of other common single element usages out there. Copper, aluminum, helium, cadmium, boron, bismuth, lead, mercury...LOTS! What to pick...hmmm...should be fun.

| I wonder how many photos there will be of the actual periodic table, instead of one of the elements. |

| Since nobody has posted a link to the table yet, here's a clicky one. |

If I shoot "scandium", who will know if it meets the challenge or not? :-p

Einsteinium would be interesting too....

I believe that a full quantitative chemical analysis of each entry be completed and filed with SC to validate the authenticity of the chemical element entries. |

Since the requirement is for the sample to be elemental, a (simpler, cheaper) qualitative analysis will suffice in this case.
I expect the NSA will be alerting the FBI to anyone posting pictures of visible quanities of Einsteinium ... ;-) |

Good point, but I think that we should consider the purity of the elements as well, hence the requirement for a full quantitative analysis. |

| There's no such thing as measuring the "purity" of an element -- either it's all one kind of atom or it's not. That's why a qualitative analysis is enough. If there's more than one kind it's not an element, regardless of the relative proportions. We are not requiring people to submit single isotopes -- a random sample of an element is fine for this challenge. |

| Humans are carbon-based, so a self portrait would cut it, wouldn't it? :0 |

I think I get it now...
A 14K gold ring (typically an alloy of gold with copper) would not meet the challenge criteria for an element but a 24K gold bar would be suitable.
