Canon S1 IS on the nose

We have nice bourgainvilla creeper inthe backgarden. By accident it
got included in a birdpicture with the Canon S1 IS and it did not look
right. Well I have access to a Pentax Optio S and an Olympus 2100 IS
so I took three pictures one after the other with only a few minutes
difference in time.
I made an IrfanView Slideshow and placed that on my site for comments.
It is an exe file with 5 seconds delay and will therefore download -
there is no virus or other trouble - scan it if you like - it is at
http://www.members.iinet.net.au/~borge/Flowers.exe

You will I suspect notice that the Canon has a very poor red. I have
made pictures with the White Balance in Sun and AUTO and there is no
difference between the two - I wonder if there is an explanation. Both
the Canon and the Olympus have a UV Filter added. I have tried to take
them off and there is no difference.
Any suggestions - please

In my experience Canons have always had poor reds. Both my S30 and S60
have always exhibited pinkish looking reds, and I always have to boost
the red level in Photoshop. They also can't accurately reproduce
colours that have a lot of red in like purple either.

The only suggestion is get another make of camera, although I'm
sticking with my Canons for the time being, even though I have been
well aware of the red problem from the very early days of ownership of
the S30.

Maybe my eyes aren't as discriminating as others, but I believe that my 20D
captures reds very well. One of the problems that I had with my previous
digital, an Epson 3100Z, was its failure to display correct color in the red
zone. The 20D seems to be very accurate.

I've been considering getting a 720nm IR filter (R-72) for my S1,
am I to interpret that the red sensitivity might be an issue?
BTW: I took some bougainvillea shots over in a local park about a week
ago and they came out fairly close with no UV or other filtration, not
as pink as those in the pic2exe show, but more of the true magenta.


Well out here (Western Australia) we have lots of Bourgonvilias and
they range from near yellow to all sorts of other colours. There is no
substitute for taking shots of the same part of the bush with
different cameras.

Believe me I am otherwise totally happy with the S1 but I am going to
have words with Canon on the subject. I am surprised. I am a retired
TV tech who was in the job when we had to finalise the colours in the
customers home at the very start of colour TV.

Not two sets came out of the factory with the same adjustments. We had
the gear for setting them up properly - not the money nor the
showmanship but we challenged people to walk down the street and ask
the big shops to put all the sets on the same station and then ask the
salesman which set displayed the right colour; and I was this long in
seeing the discrepancy - I must be losing my sight and mind with age.

Thanks for the comments all of you.

There's one other issue that I don't recall being mentioned. Some cameras
have some spectral response beyond what the eye can see, and this affects
the colour rendering. I have seen it both on flowers (blue/violet leaves)
and on artificial fabrics with (perhaps) brighteners added to convert
near-UV into visible light. Now all cameras of the same model should
respond in the same way, but of course they aren't checked at the factory
for this out-of-band wavelength response. Different makes and different
models will respond differently.

Perhaps this far-end spectral response is contributing towards the colour
issues you are seeing?

Cheers,
David

When I used film cameras, I always used Fuji film because I took a lot
of photos including leaves, trees and such; Kodak - great for skin tones
- rendered most greens with a pronounced blue cast. I imagine there are
similar issues with digital cameras.

When we reduce the whole spectrum of light to sensors of three types,
normally RGB, we are relying on the shortcomings of our vision to make
everything come out right. There are bound to be some glitches.
