hi all:

can anybody explain to me what was wrong and why?

go there:

http://www.arnason.no/modules.php?set_albumName=album10&op=modload&name=gallery&file=index&include=view_album.php
and check last 2 pictures (0098 and 0099) of burger king at night.
both pictures were made last night at midnight. i was impressed by
the colours, that's why i decided to take some shots.
passing this same place tonight i've noticed that something is
wrong with my pictures. both have sign "burger king" shown in
yellow or kind of orange colour when original colour is red and
maches colour of the red strap above sign. why it has happenned?

just in case i give details of pictures: both were made from tripod
from the same place at the same time (about 20 second one after
another) with no flash light.
picture 98: exposure time 1/4 sec, f number 2.8 at fl 9.25 mm
picture 99: exposure time 1/6 sec, f number 3.5 at fl 17.81 mm

thanks in advance

seems like i'm crazy but after reading steve's message i took my
camera and drove a few miles to friendly burger king to check
settings suggested by steve.

and guess what: friendly burger king wasn'r friendly no more. this
damn place was already closed and all illumination turned off.

grrrrrhhh.....

so i just came back home (0:40 am) and brought a few shots of full
moon instead.
have to go back there tomorrow night.

i just came back from friendly this time burger king where i've
made a few shots due to steve's and pete's last night suggestions.
i've placed pictures in thordur arnason's place:

http://www.arnason.no/modules.php?set_albumName=album10&op=modload&name=gallery&file=index&include=view_album.php&page=1

thordur, i thank you very much for allowing me to do it.

here is a situation:
all 4 pictures are being made from the same place from tripod in a
period of time about 2 minutes between first and fourth one.

details:
picture 117: camera set to automatic, sunset mode, exposure time
1/6 sec, f number 3.5, fl 14.46 mm. white balance set to automatic.

picture 118: camera set to automatic, night portrait mode, exposure
time 1/6 sec, f number 3.5, fl 14.66 mm. white balance set to
automatic.

picture 119: camera set to automatic, night portrait mode, exposure
time 1/6 sec, f number 3.5, fl 14.66 mm. white balance set to
tungsten mode (light source - incadescent light)

picture 120: camera set to automatic, night portrait mode, exposure
time 1/8 sec, f number 3.5, fl 14.66 mm. white balance set to
fluorescent mode (light source - fluorescent light).

and, how we all can see, "burger king" sign is still yellow and has
to be red, matching red strap above.

what else can be wrong?

When you view your orginal image in photoshop with the dropper and
info tool, you find that the RGB values for your sign are only Red
and Green, with no blue. A little more red than green. I guess
red and green make yellow. Ok, now if there are floursence lamps
powering the sign, they will actually give off a green light. So
the yellow is the product of the red transparent plastic with a
green light source.

So the human eye sees the red sign, but the camera sees the yellow
light being produced by the combination of the green light and red
sign.

Not sure this is correct, but on the other hand it is quite clear
that you are not doing anything wrong. The problem is if you will
beyond your control. Interesting and wierd, but nothing more. It
would be interesting to see what a film camera would produce.

jim:

thank you for your scientific explanation of the problem. now i
exactly know what is happenned. i remember discussion on this forum
some time ago when picture of the girl in a red or brown skirt was
posted and skirt was really black or vice versa. skirt was made
from a kind of synthetic stuff and camera saw it differently.

so i went to photoshop, took the samples of red colour from outside
letters and simply filled the letters by this colour. of course
more cosmetic work is needed but i just was curious how it will
look like. and it looks how i saw it. how i said, some cosmetic
touches are needed and pictures should look like original object
seen by human eye. you can see it now in thordur's place.

You piqued my curosity, I checked out the Burger King near me and
the letters are yellowish orange, just as your photo shows with a
red bar above. Don't know the reason for the difference in color
scheme, but it is after all the "Home of the Whopper".

The strip reflects the rather sparse ambient light. The sign emits
its own light. As a function over time, the sign will be a lot more
intense than the strip. Despite you seeing them as the same color,
the sign has much stronger light.

In essence, the sign is overexposed. If you take a flash picture of
the same building (which would take one heck of a flash) the light
reflected and the light emitted would be closer in amount (provided
you use a very short time of exppsure) and you will get the same
color/intensity.

Film will do the same thing. The human eye may work like a camera,
but it doesn't work like film or CCD. Light doesn't "add up" on the
retina; it is instantly processed and turned into a picture. That's
why you see both as red and a camera doesn't.
