LOL! $10,000 for one picture....it better be a "real" dinosaur that has ben extinct for millions of years and then suddenly appear in NYC. I can't think of any photo worth $10,000, heck I don't see how some oil paintings sell for what they do.
As far as equipment, have you ever seen the pictures from the moon expedition? They were taken by a box camera strapped to the chest of an astronaut. The astronaut could not pick it up and aim it, nor adjust any settings, nor have any special lighting and guess what, they were flawless. Too funny! The 16mm and 35mm cameras, projectors and even film have gone by the wayside. Everything is digital and can be manipulated, smoothed out, etc via computer programs. I have seen some pictures taken by a polaroid disposable camera look better than studio pictures, so there is no way to justify that kind of money for a photograph.
One more thing, a photograph on a website just sits there. If I have a process, procedure, etc. that I want demonstrated or representated it would be much more plausible to get a 3D model that can show the smallest detail and be animated in a way to describe what I am offering, whereas a still image can not do that. The only photos for websites would be "contact us" or very generic photos of items such as cars, birds, cats, etc.
Now if someone hired you to go to Afghanistan and take a picture, then you could charge for travel, protection, and time expenses which you would in incur, and maybe get $10,000 from the person that commissioned you. But even so, the picture itself would not be worth $10,000.
I don't mean to sound ugly, but I just can't see someone spending that kind of money for one photo unless they have more money than sense.
