Really?
Yes. **Converting** to an other color space does not help when you are
not shure about the origin. Perhaps you want to **assign** an other
color space, but then you don't touch the RGB values.
And how do you confirm that? Well you can't.
This is a matter of communication. There is no way arround it.
In the days of Photoshop 6 and later there is no reason to change
the working colorspace unless the customer demands it.
The general user/customer has little clue as to what they want. They
want something when they see it.
Perhaps you ask the wrong questions. Again this is a matter of
communication.
So the lesson to learn: make shure you know source and destination.
Add some "requested" fields to your order form.
Again. There are no lessons to be learned because there is NO
concrete way to tell if the color profile assigned to the image is
correct or not. Regardless correct is subjective, but if THERE is
no solid way to confirm the color space, this topic whittles down to
guessing and to me, that's a serious problem.
You can never be shure if an image has the correct profile attached.
There is no technical way to do so. It is a matter of communication
and trust. If you send me an image which is tagged sRGB I either
believe that you know what you do (so I trust you and process your
file like that) or I get back to you and try to understand how you
created the image. A third approach is to plainly "autooptimize" in
sRGB like a picture shop (WalMart or Sears style - you name it) would
do.
True, but either you have to educate them or you have to make an
educated guess.
This is old school thinking and I wish the developers would stop
pushing this ideology off to education.
In a way I agree, but then all manufacturers have to keep sRGB to sRGB.
But isn't that a bit to much to be expected from a $50 digital camera
or an $150 LCD display ? And what about different illumination of
objects in nature - some stay in 5000K sunlight, some in 9000K
shaddows and to the eye both lights are white, but for a camera one is
blue, the other yellow...
True, but either you have to educate them or you have to make an
educated guess by asking the right questions. Communication is key
here !
Yes, but this is just plain wrong because when you are dealing with
multiple users from many areas of understanding, communication fails.
Not necessarily. But I agree, communication can allways be improved.
