1) How is it better than the X-Rite Passport?
2) Since you use Presets and not "Calibration Profiles", is it possible to do dual luminance profiles with this product?
I find the Passport difficult to use in most situations where you are not shooting in studio lighting as much of my shooting lighting is inconsistent and unpredictable and would require many reference shots per shoot. I suspect this wouldn't be much different with the SpyderCheckr product.
