Can photograph effect?

Originally posted by Kumar [But then, how can we get effect of IR or UV rays through skin if our skin is not able to recieve effects from wavelengths?
Different wavelengths (photons with different energy levels) can affect different molecules in different ways.
Effect's magnitudes can be more or less but still some effect should be there.
It depends on the structure of the molecule whether a particular wavelength can be absorbed and what the result will be. Not every wavelength can be absorbed by every molecule, and most often the effect of absorption is just heat, nothing important.
One good thing you have indicated indirectly; if this is possible, it can help blind people, substancially.:)
That's not what I said at all.

I can't say how much above link is true, but still it is mentioned there.
That link is total nonsense, propped up with technobabble. Just like your theories.

You are deteriorating, Kumar. You used to be mostly able to distinguish scientifical links from crud.

Colour is energy and the fact that it has a physical effect on us has been proved time and again in experiments - most notably when blind people were asked to identify colours with their fingertips and were all able to do so easily.

Your quote is complete rubbish. Blind people are not able to identify colours with their fingertips, and you cannot quote a properly executed test where this has been proved. Rest assured, that if this was true, you would not be limited to quack sites when digging for material of this kind.

It can be in view of current status of science otherwise blinds would have not been blind.

But several other colour therapies are also there--so if we will not assess those mass....., how new clues will come into picture to science?

We do assess them. We find them to be nonsense. We move on.

Ok, we can wait. We can take as of now in science that wavelengths in visible spectrums can't effect physically without interaction through eyes? Is it clear?

Now, what are their effects through the eyes?

Light from an object passes into the eye through the lens, which forms an image on the retina. The retina sends a signal to the brain. The brain interprets the signal, we "see" the object.

Yes, are there other possible physiological effects than "seeing"?

Look at the sun through a telescope. You will then experience the physiological effect of "pain", and your eyes will be ruined.
 
Kumar said:
Are you sure that there are no other "Physiological Effects" of seeing colours other than just seeing & any of these as indicated here?
Most of these links are dealing with psychological effects of colour. What exact link are you thinking of?

The physiological effects are the ones that enable us to see.

Psychological Effects of Color

But does color have effect on our emotions and behavior? The answer is yes. But in terms of what kind of effect and how it effects, findings are inconclusive. Our reactions to colors are led by a combination of biological, physiological, psychological, social and cultural factors.

Try this one. :D
 
The brain is complicated. I don't know what happens to the information from the eye as it is being processed.

There is also information from light to part of the eye which is used to determine the body's day-night cycle.

Kumar, you asked for physiological effects, right? Why are you then only referring to sites about psychology?

Physiological Effects of Color
Pick a Color
red yellow blue green orange

black white purple brown pink



Vision is not the only form of physiological reaction humans have to wavelengths. Preliminary scientific studies show that red radiation is more likely to produce epileptic seizures than blue light. Furthermore, when blood pressure, respiration, heart rate, and eyeblink frequency are measured, the color red resulted in the highest frequency, white lower, blue lowest.

Psychological Effects of Color
...

Because ,both Physiological & Psychological Effects of Color are mentioned on this site.

The effects noted here are effects generated in the brain after the light input has been handled by the eyes. It is perhaps not a psychological effect, but is also not a physical effect in the sense that we have been discussing here.

So yes, epileptic seizures and so on are physiological effects, but they are caused by problems with treatment of certain signals in the brain, not by the light itself.
