brad_farwell Posted May 18, 2009 Share Posted May 18, 2009 <p>Hi folks-<br> I have an imac 24" flatpanel, calibrated regularly with an i1d2 puck. A couple weeks ago (after a year or so of excellent color fidelity), I calibrated it again, and all of a sudden the highlights had a definite green cast. Seemed crazy, so I calibrated a couple more times, same result (tried with other variables as well - turning off ambient lights, etc., etc.)<br /> <br /> I notice that on the graph at the end of the calibration process, even the graph shows that it's going to be green- the green response is a nice straight 45-degree line, while the R and B channels fall off a bit at the high end.<br> My questions-<br> Isn't this what the calibration is supposed to notice and fix (knocking down G to match R and B, so I at least have a neutral, if slightly dimmer, highlight?)<br> Am I misunderstanding calibration?<br> Can I manually adjust this, or is there an obvious fix that I'm missing? I can 'see through' it a little, but it's really hard to edit photos with a lot of highlight area.<br> Any help appreciated.<br> Brad</p><div></div> Link to comment Share on other sites More sharing options...
howard_m Posted May 18, 2009 Share Posted May 18, 2009 <p>sounds like the i1D2 may have lost a channel</p> Link to comment Share on other sites More sharing options...
brad_farwell Posted May 19, 2009 Author Share Posted May 19, 2009 <p>when you say 'lost a channel,' I assume you're talking about a hardware failure in the puck, not a setting screwup? The puck is only a year or two old, max... is this usual?</p> Link to comment Share on other sites More sharing options...
howard_m Posted May 20, 2009 Share Posted May 20, 2009 <p>yes, I would assume that the puck is suffering an internal failure. Not usual but all things do break sometimes.</p> Link to comment Share on other sites More sharing options...
