Subject: Re: [office] Giving 120%
Andreas, I suspect, but don't know, that the answer to your question and the one by Dennis depends upon the representation of the color space of an image and then the application of the -100% to 100% to that value. But in the absence of knowing that value, I don't think the percentage values are going to be very informative. Hope you are looking forward to a great weekend!
