The only time I've had problems with 'pinking' was in converting RGB to CMYK for print reproduction.

Hi Derin,

 

Thank you. I have calibrated the camera etc and my lighting set up never changes. I also tried the new reproduction mode but I really don’t like it. I’m going to do some more playing around with it on Thursday. I think you might be right in that it’s the set up causing the problem. I’m having some improvements done to the room soon so will see if that solves the issue.

Dear Claire,
Phocus reproduction mode relies on a calibration setting, is it possible that someone had used that to create a calibration once that is no longer valid with your lighting? It is also possible that the Factory calibration does not play well with your particular setup. Since you seem to have a color checker, give the user calibration a try, it is very simple and takes no time. Just make sure that the target is evenly lit, I would put it in the 60% center area of the frame to avoid any edge aberrations.

There is also a low-gain setting since 3.3 that will help with overexposure issues.

Hi All,

As you may remember I posted a question about colour management a while back and it prompted quite a discussion. Well I've been trying out various methods that people have suggested with varying results. At the moment I'm back to trying the reproduction mode with Hasselblad and Phocus. The problem that I am currently finding is that everything has a pinkish tinge to it when in reproduction mode, which goes away in Factory mode. I am neutralising on patch G5 and in Factory mode this gives me perfect RGB readouts and so is definitely neutral, but in Reproduction it no longer reads as neutral. Is this normal? Also I would like to know the LAB values that people use as the ones I have been recommended produce overexposed images.

Thank you,
Claire
