I was posting this to see if anyone out there has used the passport color checker with Aperture 3. I understand there is an automatic calibration plugin that works with Lightroom, but Aperture would be a manual job to make use of it. My question is, is the color checker really worth it? I like the idea that it could improve the color fidelity in my photos, but on the other hand, I have survived without it so far. Any real world experience and/or advice is greatly appreciated.
