How do you suppose to make a color image with only two filters?
Please, come and explain it all to us seeing how you think you know.
A filter is a way of limiting what passes through it, in this case, light.
If it was only one filter, ranging from 400nm to 800nm, it would let through all of what we call visible light.
If two filters are used, say one from 400nm to 600nm and other from 600nm to 800nm, the
combination of the two filters is the same as one
filter for all.
See it like this:
You have a building with one door with free access, independent of age. Through this door any one can enter.
Another building has 3 doors: one for people with 20 years or less, another for people above 20 and bellow 40 years, and the third for people 40 or
above.
In this building also all people can enter, they only do that by different ways.
In the image you posted, you can see that there is a continuous line from 400nm to 1000nm, meaning that
all the visible light can pass trough
the
sum of the filters.
Obviously, if you only show what one filter saw, you can not have true colour.
Your eyes DO see in RGB, and more importantly your
Monitor outputs in RGB.
IF the output is RGB then the input must be RGB in order for it to be true color.
Any color cam in the world does a better job of making color pictures.
No, we do not see in RGB.
From the Wikipedia:
The three kinds of cones typically respond most to yellowish-green (long wavelength or L), bluish-green (medium or M), and blue-violetish (short or S)
light (peak wavelengths of 564 nm, 534 nm, and 420 nm respectively). The difference in the signals received from the three kinds allows the brain to
perceive a wide range (gamut) of different colors.
Also, RGB does not represent true colour, only a limited rang, as you can see in the following link.
RGB colour gamut
Also, the colours you see in a CRT monitor are different from those you can see in a LCD monitor.
But maybe you mean "true colour" as defined by Microsoft Windows display drivers? In that case you are limited to 256*256*256=16777216 different
colours (or 65536*65536*65536=281474976710656 if your drivers
and monitor can display 16bit channels).
Your eyes can (maybe, see * below) see more colours, or at least they can see more gradations of colours that your monitor can show.
Even in a 16bit per channel monitor, display card and drivers you can "only" have 65536 different levels of Red, Green and Blue, but it is very
common for people to be able to see more than that, at least for some colours.
*But this is if you can see as well as the average person, it is impossible for a person to know how the others see colours without making tests.
Some people are blind to some colours all their lives and never notice that.
I already have.....
Are you asking me to
not post about it here?
I refuse!
If I wanted to ask you to not post about it here, I would have said that.
But that is something I would never do, your freedom to post what you want here is none of my business, unless it interferes with my freedom, in the
same way as my freedom to post what I want stops when it interferes with anyone else’s freedoms or the terms of use of this site.
Also, in your post, you did not say that you had complained to the authorities, so how could I know?
Is it cause - we don't need to see the skies - cause we really just need the DATA. If you really need to find minerals - You
need a LAB!! In a sterile box.
