The XRite one looks like it's got a bit of haze/fog over most of the colors.

My first reaction too, but then realized that it's a different Passport than my Passport. The background on mine is very dark. Darker than the plastic case, almost as dark as the black patch. Andrew's Passport has a medium gray background. Plus the shot is overexposed (white patch = Lab L of 99). Makes it look hazy, but it's not.

It's a 'pre-release' (beta) Passport, that's why it looks different case wise. What's important of course, are the patches themselves.
I regally shoot at +2/3 and further, if the white of the raw were over-exposed, the Passport software (and presumably BasICColor) would pop an error.

Here's what Photoshop reports on the white patch of the TIFF (not JPEG):
I think the right side appears 'hazy' due to it's angle to sunlight. The left side (the black) doesn't look that way if you compare the two. So compare that side or better, far better, the TIFFs I've provided.

It occurred to me that part of my testing today could be flawed but it also points out an interesting observation about DNG profiles.


First off, the Passport target seen here (a beta) was shot today and a profile was made using the latest version of BasICColor. The examples I provided between it and the X-rite generated profile are (I hope most would agree), very close visually. The Passport DNG profile while created from the same target was shot elsewhere and created back on January 8th of 2014! Further, the capture of this target today may not be "ideal" as some have mentioned what appears to be "hazy" from I think, the angle of the target with respect to the sun.


Now a better testing methodology would have been building a new profile today from both products from the same capture and with perhaps a better angle of illumination on the target. And maybe I should do this.


But despite the vast differences in when and to some degree how the two profiles were built, the differences of the two profiles on a number of raw images with different color characteristics and shot over a range of locations are visually tiny! I think that's kind of interesting.
