:D
I showed here, with the first two mouseovers how similar a 3C 75 CRI and a Nichia 219A 92+ CRI can be. There are differences though. Just because white is corrected to look white, does not mean that all colors will look correct. You will see this more easily if you compare light sources with completely different kelvin ranges. But yeah, most of my examples shows that the difference in colors is close to zero when corrected.
Feel free to try and make a 92CRI WW light looks as good as sunlight on a outdoor shot just by correcting the WB. Not going to happen. Sunlight will have the edge even when both have the right WB.
But for everyone who is really into photography, CRI is not crucial. Because once you get the white balance right, most things looks pretty good, and if it doesn't look like you want it to be, colors can always be tweaking independently in post production. If you take a picture that is lit only with artificial lighting, then its not like anyone can see and see if you are using a 70 or 80 CRI light source anyway.
Its actually the people who are not that into photography and have equipment or software or know-how to get the best out of their gear that will benefit from using emitters that work better with their cameras auto whitebalance. The typical Nichia 219A just works very well with most cameras autowb. This is probably the main reason why some say high cri is very important for photography. But for 99% of professional photographers/freelancers, CRI is not something they are even familiar with. Its not a concern.
hmm. I think I drifted a bit off topic there.. :p But its a little bit relevant.. 0:)
