I don't have a very advanced knowledge of fine color adjustments, and am not particularly keen to be going very far down that rabbit hole. Shooting a color card, dragging a DNG file onto an app and choosing the new custom profile in Lightroom [then making it the default], that I can do. There are a few colors the A7 seemed to struggle with. The top shot here with Adobe's "Camera Standard" is wrong. Last spring I wrestled with HSL to try and get it closer for the online store. Now with the app-generated profile, it's pretty much automatic. Since most of my shooting is to sell glass art, I'm kind of kicking myself for waiting so long to try this. If you want to get particular, you can generate a profile for each different light source. (Or even combine two sources for an "all-purpose" profile.) I don't have a proper daylight sample yet (January in Oregon, might take awhile) but the one I made with my tungsten light looks pretty good on landscapes! ("Camera Standard" on top w/ contrast & saturation added, ColorChecker profile w/ no adjustments on bottom.) I'll try a "daylight" profile as soon as I catch a little sun (easier said than done in Oregon in January). I didn't really get the ColorChecker for landscapes but I have to say, I like this look better than anything else I've gotten in Lightroom, thus far. My Canon camera used to render colors somewhat differently than the Sony. After profiling it, it looks like I'll be able to interchange the two more: (Sony on left, Canon on right - exposures adjusted to match.) It's not quite a perfect match, but it's close enough for my slightly color-deficient vision and my online store buyers who don't calibrate their monitors. There are other systems and techniques for doing this sort of stuff but thus far I'm pretty excited about the ease and the results with this X-Rite "Passport".
