I still do. It says spherical. And specifies it not be circular. Doesn't say nuttin' about hemisphere.
I reckon if it's got a predominantly spherical surface... it's gonna be good enough for me.
But hey. I'm a nice guy :P

Honestly though, for me anything that could be described with the word sphere in the sentence (so long as the two preceding words aren't "not a") won't be critiqued as not meeting challenge too harshly.

I'd say it'd get a few dnmc's, but it consists of hemispheres.

Maybe that's me though. I don't like to DNMC things until I've had a good hard think about whether it actually does or doesn't.

ud seriously DNMC for a hemisphere?? wow in that case you might as well DMNC all of us because photography is not 3d so techincally speaking they are ALL just circles.

Indeed. Even the best shot can only imply the sphere. If you can make a hemisphere look like a sphere...AND make it interesting and original...we'd like to see it. I'd say bring it on!

What is I take a picture of a ball being run over by a car. A sphere that's now an ellipse. No one better shoot that by the way. That was MY idea. :)

Seriously though, when I am voting and I see a object that is roughly spherical in shape I'll be happy. Now egg shaped is a different matter. I will beat you down with a ONE stick... :)

Correct... WHAT the subject is is not as important as what we see.

If you have an hemisphere object and shoot it top down, it looks like a sphere. The most we'd ever see of a sphere is half anyway. But if you shoot it side-on, like a waterdrop, then it's really not a sphere and thus is DNMC (IMO).

It has been said that man cannot produce a perfect sphere. How can that be said if we have nothing perfectly spherical as a reference to begin with?

But we CAN produce what we refer to as a sphere... and a dome is not a sphere... Nor is a water drop on glass.

What would you say to, say, a marble that was halved, and the title being 'broken sphere' or something. It fits the bill. But it's two hemispheres (ish).
That's not a bad idea, actually. Where's my axe?

Interesting collection of essays that address some of this: "The Relativity of Wrong" by Isaac Asimov. The basis of the discussion is that there are degrees of correctness.

As regards "spheres", a picture of a water droplet on glass is much closer to correct than a picture of a frog. A picture of a plum is closer to correct than one of a water droplet on glass. A golf ball...a "unsquashed" ball bearing...a droplet of oil afloat in a water bath...a picture of Earth (per Asimov, actually an irregular oblate spheroid)...none of them are going to be "correct".

But they might make some great pictures!

My view on the last few posts is: A "sphere" refers only to a 3-d object, a ball if you will. It is clearly defined. A circle is not a sphere... A dome is not a sphere... a blub is not a sphere... A sphere, is a sphere... I thought there were a lot of "non spheres" in the challenge...

I have no problem with partial spheres. After all, a hemisphere is definitely PART of a sphere -- it doesn't say that you have to photograph the entire sphere. But then again, I'm pretty open to interpretation. However, there were a number of photos where I was hard pressed to find a sphere. I'm going to look more closely in a couple of day when I vote.

I'm kinda turning over to your side now.
There are some very... unique takes on the word sphere out there!

I've gotten to where I not longer give a 1 for a DNMC figuring that there might be some way to shoehorn in what the photographer submitted into the topic...

However in this challenge, I was forced to hit the 1 several times... And without giving any photo away: "bulbous" is not "spherical" :)

I feel bad if I give a 1 for DNMC. I tend to just subtract a few points from what I might have given it... of course it depends on the severity of my interpretation of their entry.

Well, I posted something here from Cornell that says there isn't such thing as a perfect sphere... so everything's getting 1's from me!
