The ColorChecker Passport is an excellent small, portable target. Really, it's almost perfect for field use; there's very little I'd personally do differently if I was designing it myself, and what I would do probably isn't practical from a mass manufacturing perspective.
If you understand that colorimetric accuracy is *not* the goal of DNG profiles, they serve their intended purpose rather well. But if you're looking for colorimetric matching, run away from DNG profiles and anything else to do with Adobe's processing of raw images and color profiling as far and as fast as you can.
Instead, you're looking at a long and bumpy road...but the view from the top once you get there is spectacular. For that, you need an ICC-based workflow and software that can perform linear raw developments. There are many options; my favorite is Raw Photo Processor for image processing and ArgyllCMS for ICC profiling. You'll also want a target with many more patches than the Passport offers, though the Passport is still very useful for setting exposure and white balance (but by building a profile and analyzing the results, not by clicking on selected patches). I went the homemade route for the chart, which is what I'd recommend for serious work.
Of course, that also means you need a spectrophotometer -- but it's an essential tool for anything to do with colorimetry so you really don't have much choice in the matter. Here again it's really hard to beat or go worng with the X-Rite product -- preferably the i1 Pro, though the ColorMunki is, by all accounts, a very respectable instrument. And, again again, ditch the bundled X-Rite software in favor of a real tool such as ArgyllCMS or something expensive from the commercial realm.
Cheers,
