How to choose LEDs for a lamp for photo and video shooting (CRI or something else)?

How to choose LEDs?
I want to make a stand for photos for documents and for product shooting + lighting for video shooting.
The question arose in lighting, or rather in color reproduction. I think that the lens and the matrix perceive color reproduction a little differently. Therefore, I don’t know how correct it is to look at CRI?
Maybe someone knows how to choose LEDs for the lamp so that when shooting there is the most beautiful picture, so that the colors are natural and rich?

That's right, you need diodes with a high CRI, more than 90.
But the result will still not be the same as on the street.
The photo definitely needs a flash.

The camera, unlike the human eye, can correct for white balance and then no one forbids doing color correction in post-processing.
The problem starts when you have a bunch of lamps with different temperatures, etc. and the fact that in such lighting you do not see the picture as it is.
Nothing to do without a flash anyway.

Color reproduction is not what you think. But in the context of the question, it doesn't matter. It's also not about the brand of LEDs, but about CRI. You can, for example, use Bridgelux Decor which has a CRI of 97-98. You can even mix different color temperatures.
But the main thing you have to pay attention to is the type of LED driver. Because if you choose something with dimming, there will most likely be PWM, which will give a stroboscopic effect on video. I used the MeanWell drivers for this most often.

It is almost useless to look at CRI. You can mix the phosphor in the diode so that the CRI will be more than 80%, and the light will even look (and in the photo too) with an unpleasant green / blue tint.
There are more modern techniques such as CQS or TM-30.
Ps but in general, all more or less normal cameras can adjust the BB on a white card.
Pps Chinese sell ready-made led strips for photoboxes. Yes, and their flashes cost a penny. Put them on the radio synchronizer and forget about the problem
