Can photograph effect?

[Donks]

Donks, flume,

The main idea is that we can get reflected colour/wavelengths effect provided photo is of true colours as of that person. Since three basic colours can make all visible colours--we can think possibilities of somewhat true colours. On studio photo, they use black cloth as backround & black absorb all wavelengths. So if photo is taken in studio & used white light, I think colours of photo can be much similar--so the effects.

What effects? Is there an effect of being in front of a person? Is there an effect of being in front of their picture? Describe the effect. Prove it exists.

Effects by reflected wavelengths/colour of a person or by his true colour picture.

Is it not true that reflected wavelengths which hit us via eyes or on skin can effect in some way or the other?

 

[Donks]

Effects by reflected wavelengths/colour of a person or by his true colour picture.

Again with the mechanism. That is not the question. Pay attention: What effect do you think is produced?

Is it not true that reflected wavelengths which hit us via eyes or on skin can effect in some way or the other?

Via eyes, yes. Via skin, how? Enough speculations, Kumar, it gets tedious. What effect do you believe there is on the skin from photons reflected off a person? Stop avoiding the question. If you want your questions answered, answer a question for once.

These are some Interactions with Radiations.

The primary mechanism for the absorption of visible light photons is the elevation of electrons to higher energy levels. There are many available states, so visible light is absorbed strongly. With a strong light source, red light can be transmitted through the hand or a fold of skin, showing that the red end of the spectrum is not absorbed as strongly as the violet end.

While exposure to visible light causes heating, it does not cause ionization with its risks. You may be heated by the sun through a car windshield, but you will not be sunburned - that is an effect of the higher frequency uv part of sunlight which is blocked by the glass of the windshield.

They put some kind of fiber-optic pad on the back of the knee which was able to shine bright white light on the skin without heat. They did get an unexpected significant effect, I forget what - I think it shifted the sleep-wake cycle some amount.

I would imagine having a "pad" taped behind your knee plus fibre-optics hanging off you plus some sort of "box" attached to you day and night would indeed put some sort of strain on your sleep-wake cycle.

I continue to submit the following evaluation of Kumar's state of investigative and cognitive ability:

Finally, some answers. Now Kumar, in regards to visible light hitting skin, what does it matter if the photons come from a person, a picture or a rock?

There can be specific patterns of wavelengths arrangements in a spectrum emitted by any substance, photo or person--which can effect accordingly. RBG can be differant from BRG or GRB? Moreover, brightness, dimentions etc. as I pointed out previously.

 

[flume]

Kumar, I'm sorry, but I think we are not communicating at all. Maybe it's a language problem.

Anyway, the answer is no. There is no specific effect.

The link you provided mentioned heating, and electrons jumping to a higher orbit. We know what happens to electrons that jump to a higher orbit, don't we? Say it with me: They decay back to their original orbit while emitting a photon. Good. The leap from here to assuming that a specific visual pattern would have a specific effect is ENORMOUS. You'll have to walk us through it.

RBG,BRG, GRB? What the hell are you talking about? The color system is RGB, red-green-blue. If you feel like changing the order, it doesn't matter as long as you don't instruct a red pixel to use the green value (or whichever other combination).

Brightness depends on the number of photons. More photons, larger effect. Which is heating. So...?

(I'll take a shot at Kumarthink...)

It depends on the order in which you light the candles in front of the photograph - whether it's the red, blue or green one first.

I am talking about wavelengths arranged in differant spectrums.
You may refer flume's following posting;

If I understand what you're asking here, the emitted or reflected light travels the way it came from the molecules in the material. It is not normally sorted out spatially by wavelengths the way a rainbow is. That ordered spread of colors is a result of the specific material it came from - the curve of the raindrops in a rainbow, or the geometry of a prism. Normally you wouldn't get that kind of arrangement

Thanks for not answering any of the questions. Ok, take your specific pattern, it's photons of various wavelengths. They hit skin. Per your link, they heat it up and cause some electrons to jump to a higher orbit. Now what? What special effect do you think is caused by the spectrum coming from a person and not from, say, a brick wall?

 

[Checkmite]

...Agur, is that you?

I have no idea if you understood what I meant or not. I don't know if you understand about the visible light spectrum or not. That website you posted has a section on the visible spectrum and some other sections on color vision. You might read those again to see if you understand.

I didn't mean that there were other patterns. I meant that there were no patterns. It depends on the surface that is reflecting the light.

Anyway. Reflected visible light from any person's skin will not have an effect on someone else's skin. Reflected light from a photo of any person or anything else will not have an effect on anyone's skin.

(We ARE talking about the photo of an ANCESTOR, right?)

Any photon or emission pattern with similar energy levels & similar pattern will show same effects--whether coming from a person, a photo or brick wall. But similar energy levels & similar pattren condition should be fulfilled. It is right?

To our main question; we want to know whether effect from a person & effect from his true colour photo can be somewhat similar or not? If colour of both person & his photo matches then reflection of colour's wavelength & their pattern can be similar on other person & so effects will be somewhat similar.

Now if one gets effect of some person due to his reflected wavelengths then he will also get somewhat similar effects from his true colour photo. If other person not getting any effect then he will not get it either from that person or from his photo. The effects will be in accordance with the principle of photons-molecular interactions. Is it clear?

flume, we are talking about effects of any person & his photo not just of ANCESTOR.

 

[flume]

Now if one gets effect of some person due to his reflected wavelengths then he will also get somewhat similar effects from his true colour photo.

Not necessarily.
Again, sorry, there are no effects from the person or the photo. You will not get "similar effects" because you won't get any effects.

But the wavelengths from a person and from a photo are not necessarily the same.
This was talked about before, and it is in that section on visible light and color vision in that link you posted.

Because of the way our eyes work, your brain can get the same color information from different combination of wavelengths. This means that the actual wavelengths reflected from a photo or emitted from a computer screen do not have to be the same wavelengths as the wavelenths in the original object to give you the same information.

This is why the computer screen only needs to use three pixel colors to give you the sense of the whole visible light spectrum. And printers need to use only three or four colors of ink. But the real object might reflect wavelengths throughout the whole visible light range. It would look the same to your brain.

You could look at a pure yellow light or you could look at a combined red and a green light, and both lights would appear yellow to your brain through your eyes. But they would have different effects on a molecule that could only absorb the wavelength of the yellow light.

Do not assume that this means something about visible light having effects through the skin.

When our brain detect & recognize anything it means effects should be there & when it detect & recognize similarily(simlar person) to photo & a person means some similar effects happened in brain. No our body activity influenced by outer exposures, should be possible without getting effects.

I think everything i.e. brain, photography works on three prime colours & their combinations. In us, we deal with the cells not molecules & whatever brain detect & recognize will be by the cells. So the effect of mixture of two colours on cells will be same as from a person or from a photo. Furthur, our brain also recognize photo of a person. It may mean that 'only colours are not relevant but pattern of emited wavelength or dimentions(may be all points as I indicated in previous link) can also be relevant.

Do not assume that this means something about visible light having effects through the skin.

Every wavelength can have its own effect on us. So visible lights can effect through the skin as per their properties & as per wavelengths-cells interactions.

All activities of brain should be science based. As brain detect, recognize & process information of a person & his photo & finds similarity--it means similar effects are there. No brain activity can be without effect. Moreover, whatever we feel/sense through skin or through eyes--both can also be said as brain's activity. So we cant say effects through skin can't be possible. In common, we may not be able to feel colours due to our adaptions/continious exposre/habitual to those but some effects can be still there. Anyone who can feel exposure to colour wavelengths, can be thought of getting the effects.

Translation: Several people have explained how this notion is wrong, but I hang on to it desparately, because it is needed to support my theory.

Every wavelength can have its own effect on us.

Translation: I need to keep believing this crap, otherwise my theory caves in.

No brain activity can be without effect.

Kumar, you are the living disproof of that statment !

I feel a flame-war satire coming up .

[Kumar]

Mr. Hans,

Your posting need translation in my language.

Furthur,

Do black colour absorb all wavelengths or just all visble WLs?

Do white colour reflect all wavelengths or just all visble WLs?

Is their any differance in absorption of wavelengths through eyes depending on colour of eyes?
