Let's hear your opinions on this picture.

Hi everyone
I have, sort of like, a science project for you.
How much light do we really see or how much light is a camera able to capture when we or it observes a very frosted proof coin?
Are we able to see ALL the light that reflects or bounces off that coin? I've provided a picture that may help provide an answer to these questions.
Anyone want to try to give their optical illusional view here?
Let's hear it!

ahhhh.........ha,ha,ha,....ha,ha........errrr..........what?

Placid

I guess MS63 maybe 64.

BSqr

ah come on placid, don't you know a proof when you see one.

littlewicher

I have one of those in my room.

leothelyon

LOL All you guys are one trip and a half.
Is this too difficult?
OK I'll go first.

I don't believe all the light refecting off the frost of a proof coin.......... because........oh heck, I can't stop
laughing............I'll come back later.......

The light reflecting any object is proportional to the light entering the lens,however,the light we observe with the naked eye either through the lens (or not) varies, from person to person.This is due to certain visual (anatomical)impairments in the structure of the eye itself.In other words simply put "Beauty IS in the eye of the beholder" IMHO

Yeah.......... what he said!!

I don't have a clue about the amount of light either, I'm still trying to figure out the grade on that porcupine coin?????????? It could be DCAM, but how the heck do you tell???

Bustman

Ok............this needs to be said.
What the %&*@, does the picture have to do with the question?

Bear

It kinda looks like a porcipine that got its paw in a light socket.

That hairy thing is starting to freak me out!

I just moved out of the state of Washington and in to the state of Confusion.

Holy cow Leo!!! You really do come up with some doozies Anyway, I'm going to go out on a limb here and go beyond the frosty reflections of cameo and look at the pic provided. You have pictured a lamp that uses fiber optic cable to "illuminate" light. How does that occur? Well it depends on the type of fiber optic cable....BTW Leo, does that lamp use MMF or SMF cable? Anyway, in the basic form, fiber optic cable has a center "core" wherein, light is transmitted through the fiber core at a particular angle ( /// ) "bouncing" through the cable until it reaches it's destination. In the example given, the "stripped" fiber cable allows some of the light to illuminate where it is refracting from the outer "cladding" which surrounds the core.
(None of this has to do with coin collecting BTW)
On another note, I will simply post the visual light spectrum.
Another cool one Leo

Leo-

I have know idea about the technical jargon, but you must be making a point about fluorescent and incandescent lighting. When you ran the thread on your 1942 nickel, you showed the coin with regular and flourescent lighting. The flourescent lighting is not direct making cameos appear stronger than they really are. I don't know what the hairy thing has to do with it, but when you mentioned cameos and optical illusions I figured this.

Don't leave us in suspense any longer.

Ok? I can see everyone is having a time with this and I like rich's answer and Bustmans seconding rich.

So I can see I need to add some fire to this equation. Don't we see more frost of the proof coin because we have two eyes where as the camera has only one opening. What if we were able to set up 4 cameras
to develope one photo of the frosted coin. Would the coin look twice as frosted as being viewed with two eyes or 4x the one directional view of the camera lens. I have now drawn the conclusion that 4 cameras would only be layering the photo and would make the frosted areas actually whiter then the original view of the coin. But what if a computer could sort out and combine the neccesary light emitted to each camera
and combine that light to develope a better picture.

Don't we find it neccesary to rotate a coin while viewing it to see how deep the fields are or how reflective the frost?

What conclusions can be drawn now with all that rambling BS I've just written?

Leo

goyankeez
Tell me about it, the thing was actually rotating while taking it's picture. I'm trying to illustrate how light reflects off in every direction and compare that to how much of that light we see or a camera.

MartyF
Since your focusing only on the opic fibers try adding it to what I said above.

Russ
Need any help finding your way back to.........Kansas? LOL

Bear and anyone else. It's not a poccupine.

Leo:
Now it sounds like your talking about angling the light source and the camera based on light reflection/refraction/rotation to "capture" different angle views and lighting effects....overlaying these differnet "views" into a single image maybe the answer you seek....I don't know....

Edited to add this one more statement:
If your talking about the light reflecting from the coin off of the glass of the camera lens, at various angles, where the user cannot see that reflection, obviously a lens filter would eliminate this problem......other than that, I think I'm stumped....

leothelyon

Yeah.......... what Marty said!! I think I beat someone to that answer.

I do like that one better.

Here's my guess, a camera only sees the light that bounces back directly at it and is captured through the lens. Light bounces off a coin in multiple directions due to the flow lines running out from the center which is way you need to rotate the coin around to see the full span of luster. As to why your eyes see more of the luster than is picked up by the camera I can only guess that your eyes have a wider field of vision and/or are continiously open while the lens is narrower and only open for a brief second.

That was a great answer. It would be great if technology would allow a coin to be slightly rotated for a 60 second movie. Then uploaded into an auction for viewing.

Leo

Too much information for me. I'll go back to looking for more coins to submit!!

Great thread Leo,
Using a hand- held light meter can measure the light reflecting off the coin and the light meter can measure the amount of light coming throught the eye piece of the camera(what you would see)I believe the light readings would be the same.This is an accurate way of measuring the quantity/quality of light without any human interpetation.How that image is captured on a film medium say 35 mm, can be affected by the type of light ,artificial or daylight ASA film speed which affects graininess in the print,shutter speed,and aperture of the lens, and finally manual focus/auto focus.When you develope that image, the type of paper you use,how long you expose that image to the paper you print on,Matte or glossy and the size of the print.I didn't mention filters but they can alter the image also.When all that is done and the human decides it wants to tweak the image using a computer the end result is probably not the same as what each person percives as the reality.What is reality?If a tree falls in the forest ,and nobody is there to hear it,does it make a sound?If the US mint produces a coin that nobody uses does it exist?Everybody say Amen!
