Null calibration with Spyder 3 Pro or Elite

2009-05-22 by Doug Kerr

Hi, CD,

One of my colleagues on several camera forums (a "recognized expert" in color management) vehemently believes that it is most attractive to apply no calibration to the monitor chain but rather to allow the ICC profile to do all the mediation to the monitor's native color space. (I guess what this means is that we should leave the CLUT's in the video board all with straight lines.) He is evidently only concerned with display performance under profile-aware applications.

I don't myself subscribe to this position, but often I have to help my colleagues do various things with various tools.

I have suspected that OptiCAL (which I used with a Spyder "1") would do this for us if we started the process by selecting "Profile..." (rather than "Calibrate&Profile" from the File menu. Is that so? (This might just result in a profile with no vcgt tag - I haven't had time to try that yet.)

Then, will Spyder 3 Elite allow us to do the same thing?

If not (and in any case, of interest to Spyder 3 Pro users, like myself at the moment), is there a target definition (*tgt file) that will produce this result? I note, for example, that there are targets supplied that leave the native white point in place (but leave the calibrated display with a certain target gamma curve, not the native one).

Thanks so much.

Best regards,

Doug
