Well, that's odd because you claimed to be able to see it before when I explained it to you.

No, the other way out of this is for you to follow through the implications of your own claims to see why they don't work.

It's right here:

4. The wavelength of that light will also match the absorptive properties of the object at the time that light reaches the camera.

But these claims are inconsistent for any case where the object has different absorptive properties for the earlier time when the light bounced off the object compared to the present time when the photograph is actually taken. Points (3) and (4) are not consistent, and this is a big fat contradiction right in the middle of your account of real-time photography.

At the film.

The wavelengths.

4. Did the light present at the camera initially travel from the object to get there?
Yes.

5. Can light travel to the camera without arriving at the camera?
Of course not.

6. Can light travel faster than light?
No.

7. Is wavelength a property of light?
Yes.

8. Can light travel without any wavelength?
No.

9. Do objects reflect light or does light reflect objects?
Objects reflect light.

10. What does a reflection consist of?
Light.

11. What does light consist of?
Photons.

12. Do you agree with our account of what it means for the ball to be blue (i.e. that it is presently absorbing all non-blue light striking it, and reflecting from its surface only the light of blue-wavelength)?
Yes.
Do you agree that real-time photography is impossible given these answers?

If so, then which of these above answers do you think can be plausibly changed?

If not, then please answer the following: You've agreed that the color of the photograph is determined by the wavelength of the light at the camera, which has previously travelled from the object to get there. So if the object is blue at the time that light is arriving at the camera, and was not blue at any moment before that, then...

Why is the arriving light of blue wavelength?

What color wavelength was that light just before it arrived at the camera?
Bump.

She won't understand what you're asking. For her, such things as images, reflections, and even vision itself are irreducible. She really doesn't have any grasp at all of how reductive explanation works.

Perhaps, but I think it is more basic than that. Her brain can't do much when it comes to learning new concepts and forming new connections. It is frozen in time. What she has managed to learn, when her brain was capable of such things, is Lessans nonsense. So if you are to have any chance of communicating anything at all, it will have to be in terms of Lessans conceptual framework. This will be difficult since that framework is mostly a muddled mess. And thus we have peacegirl, yet another basket case on the internet.

I think this is peacegirls way of recognizing that if anybody's mind is gonna change here, it will have to be her's. And she can't change her mind. Her brain is not in good enough working order for that to happen.

In her mind she believes it is true, just like Lessans believed that academics looked down on him for his lack of education, when really it was his arrogance that put him in a bad light.

Actually, you have repeatedly claimed that we can't take pictures of light. Lady Shea introduced the example of the rainbow, and other optical phenomena, as a way of demonstrating, contra your claims, that we can indeed take pictures of light.

What, exactly, is an "instant lightwave"? Is it anything like an "instant reflection"? Now you have two terms you need to define.

How did "the lightwave" get there? How long does "the lightwave" stay there?

When you're showering is any specific water at your elbow the instant you think about the water at your elbow, or has it already gone down the drain and there is new water at your elbow?

Seriously, the light at the camera when you start to push the button to take a picture is not the same light at the camera when you finish depressing the button. It moves too fast for there to be any kind "the" lightwave

LOL lightwaves that un-travel instantaneously without anything going from A to B, and yet transfer the correct information at infinite speed? Excellent! Please demonstrate this device you have just invented for sending messages into the past as soon as possible. We should be able to detect the microseconds of time difference over quite short distances. Think of the implications for computing alone!

Oh wait - we already use fibreoptics to get us the fastest possible connection speed between nodes in computing and it doesn't work that way. Ah well!

And two new ones:

How can we tell if an object is 'out of range' or 'out of the field of view' of a camera?

Since you accept we can detect light, do you accept that we can work out where the light is coming from when it enters a camera? Even roughly, such as 'in the top/bottom/right side/left-side of the viewing angle of the camera'?
Of course we can tell where the light is coming from depending on where it lands on the film.
Great, we can tell where light is coming from by where it lands on the film.

So peacegirl, given we can tell where the light is coming from, we can use special film that also reacts to the colour of light and work out what colour of light comes from where too, right?

In other words, we have all the information we need from the light landing on the film to build an image; there is no information in our vision beyond these two things. So why can't we use just light to construct images afterall?

By the way, how do we tell if something is 'out of the field of view' of a camera?

I can only reconcile this by saying that the lens acts efferently, just like the lens of the eye. If the object seen is within the field of view of the camera when a picture is taken, the distance as far as the lens is concerned is within that small space of visibility. And even if light travels at a finite speed and we can only see the first photon before the last which would indicate that red would come before blue, the light is traveling so fast that when it strikes the camera it would be the color of blue, not red. You have to remember that the distance from the object to the lens, according to the camera, is just as close as the lens is to a flickering candle in a dark room. Does that help?

Yes, you were given the explanation. Here it is again.

You cannot photograph an object when the apparent size (due to distance) is too small for the camera to resolve. You can correct for the apparent size due to distance using a telephoto lens and or adjusting exposure time.
I'm not even referring to size. It could be the moon (that's not small, is it?) just out of view of the visual range, and you can't see it unless it comes into the visual range in order to be resolved.

Field of view is not limited by distance. You are still misusing the term.

So long as the light is traveling at a finite speed it will remain possible for the object to change color while the light is in transit, so this doesn't help. Afferent vision/photography agrees that the time delay will usually be very small. But very small is not the same as non-existent, so this doesn't help you.

Not at all. And you didn't answer my questions:

Why is the arriving light of blue wavelength?

What color wavelength was that light just before it arrived at the camera?

(Why don't you explore the possibilities for yourself? Can you think of what the problem will be if the light WAS blue just before it arrived? Can you think of what the problem will be if it was NOT blue just before it arrived? Which option, if either, seems more plausible to you? If neither is plausible to you, then what does that tell you about real-time photography?)

Huzzah! We are back at efferent cameras - only now it is the lens that acts efferently through the magical action of "focusing"! You just latched onto the nearest thing you do not understand, and claim that it is the reason it works, because of magic.

Waffle snibbly gipwip? Field of view is "in the area where things can be seen". That means that you just said the following: "If the object seen is in the area where things can be seen, then as far as the lens is concerned they are in the area where things can be seen!"

I see the apple does not fall far from the tree.

Lol? So even if Lessans is wrong he is still right because it would happen so fast we would not notice?

According to you, lenses are magic and if you have one, distance (and physics) are magically suspended.

It's not just angular Spacemonkey; it's the entire span of the observable world.

The field of view (also field of vision, abbreviated FOV) is the (angular or linear or areal) extent of the observable world that is seen at any given moment.

That's not true. I'm saying that the light that is seen has reached the field of view of the telescope with the help of magnification.

Not at all. It's just that we're confusing the issue. I'm discussing real time vision which includes a lens. Light still travels and can be detected, but whether that light holds the image of the past is another story.

Your link supports my point and not your own. FoV is the angle, not distance.

You're the only one confused. Everyone else can understand the information provided by the experiments already performed.

So you're back to the strawman of light holding images, and thinking lenses have magical powers. Do you think this will work out better for you this time around than the last 999 times you've tried making such claims?

No Vivisectus. There is no magic. I am trying to figure out how light works because I know there is a way to reconcile this. I'm not trying to latch onto the nearest thing; I'm trying to show that there is a way to make this model work. How would you feel if it was disregarded only because people didn't look deep enough?

Wrong... then as far as the lens is concerned they are in the field of view where a picture can be taken or the visual range where things can be seen..

Why do you have to match the nastiness level of everyone else? Why can't you stay nice and still get your questions answered? Because the apple doesn't fall far from the tree. :popcorn:

As far as the lens is concerned, yes. The blue would be the emitted or reflected light which would be at the lens because the distance would not be the lightyears away that you're imagining.

You have to remember that the distance from the object to the lens, according to the camera, is just as close as the lens is to a flickering candle in a dark room. Does that help?

It's not that the lenses are suspended, it's how the lens works in relation to space.

Yes, you were given the explanation. Here it is again.

You cannot photograph an object when the apparent size (due to distance) is too small for the camera to resolve. You can correct for the apparent size due to distance using a telephoto lens and or adjusting exposure time.
I'm not even referring to size. It could be the moon (that's not small, is it?) just out of view of the visual range, and you can't see it unless it comes into the visual range in order to be resolved.
Apparent size means the size something appears to be. Objects appear smaller as they get further away, correct? When the apparent size is too small for a particular camera to resolve an image, that camera cannot create an image.

Just like when the apparent size is too small for our eyes to resolve we can't see (resolve) it.

In order to create an image, either with our eyes or a camera, we have to make it so that the apparent size is large enough to resolve. We can make the apparent size bigger, allowing us to resolve an image, with lenses (which are not efferent. We know what lenses do, we build them. You can experiment with lenses yourself).

This is why we can't see bacteria without lenses. We don't change the actual size when we look through a microscope, we change the apparent size. This is why we can't photograph microbes with a regular snapshot camera, it must be attached to a lens that allows us to make the apparent size bigger so we can resolve it on film or at our eyes.

No, there is not. I have nothing to be in denial about. I am not 15 so don't care about "popularity". I am an atheist, and a progressive, so certainly don't think the majority is always right.

I have taken it upon myself to learn how stuff works. There is no mystery here, everything I have said is well explained and can be predicted by optics.

Are you suggesting that somehow light does not arrive at the lens in the order that it was emitted. In other words light from the source, just arrives whenever and just because some is emitted first that does not mean that it will arrive first?
I'm saying that light is a condition of sight. This means that we see the object in real time using light as a medium. What's with you doc?

:loud:

So we see in real time using light as a medium! Unfortunately light does not travel instaneously! So if light is the "medium" by which we see we don't see in real time! Derp!

This doesn't change anything. The lens magnifies the size so it can be seen. Lessans said that the object has to be large enough to be seen, and this meets the requirements. If the object is small but gets close enough, it can also be resolved (as you put it) by a camera.

Hello? What have I been saying all along. Lessans stated that the object has to be large enough (which means that a small object can be magnified to make it large enough), or bright enough.

I'm not disputing what telescopes do. They are an amazing technology that works.

But this is in keeping with what Lessans states. Once again, the apparent size of the bacteria is made larger by a microscope. We know that bacteria are too small to be seen with the naked eye even if they were right in front of us, so we need this magnification. But we don't need magnification to see an airplane because it's large enough to be seen as long as it's within our visual range. If it's not, the camera is unable to focus just the light (which it should if afferent vision is correct) being reflected from the airplane so that an image can be resolved on film.

There is nothing you said that I am disagreement with, so why are you trying to use this as a way to discredit what Lessans is saying?

So the lens magnifies the object itself? Is that what you are saying? It makes distant objects grow big enough to be seen??

There is though. Lenses just redirect light - it is all they do. They do not have a magical power called "focusing" that is completely unexplained, but somehow works outward.

As I said, the apple doesn't fall far from the tree. That is almost as good as "People are compelled to select that which leads to the maximum satisfaction.", where "That which leads to the maximum satisfaction" is only defined as "That which people end up selecting".

It really doesn't, right down to using imaginary persecution as an excuse to avoid admitting you are plain old wrong. Which you dishonestly continue to do.

I cannot believe you actually admitted to that. As far as the lens is concerned, distance is imaginary?

Exactly. Distance and physics are suspended because of the magic in lenses.

Well at least you just come out and admit it is insane.
