Are there Hi CRI clip-on grill lights? I'm off to Google it...
not sure whats out there
I use a Maratac AAA w Nichia clipped to my hat. The Tool also works. Both have reversible pocket clips.
There is an Aluminum version of the Tool w Nichia also,
on sale for $11, its a killer deal!
Pic #4 looks 100% spot on perfect.
Is that the iPhone?
yes pic 4 is daylight, no flashlight, taken with iPhone, automatic white balance
When I take CRI pics, I use a camera set to "daylight" white balance to eliminate any auto white balance effects. Then the high CRI lights look good, and everything else looks terrible.
My understanding is that the HCRI LEDs will have a different CRI and/or color temperature at lower drive levels, maybe not as good. And that reds are the main difference - try looking at a rare steak with various CRIs.
daylight white balance sets to 5000k I believe, so it will make 4000k look "warm", and 6000k look "cool". CRI is a separate factor than white balance. Yes constant current allows some tint shift at low levels. However, High CRI at low levels will still be higher CRI than Low CRI at any level.
and yes, steak with high CRI looks delicious, at low CRI it looks like a dead zombie
auto white balance chooses the coolest light in the photo to set to
so if I put a cool white light in a photo, it will set to that white balance. like this
note the color of the middle light, it is what I see, during the day when my brain is set to daylight white balance
if I keep the neutral white in the photo, but remove the cool white, iPhone auto white balance, will set to that neutral white balance, like this (same two lights on left above). I do see that middle light as white, not pink, at night, when my brain is adjusted to indoor incandescent for its white balance.
the time of day when a photo is taken, affects the color of the beam. Our brain also sees the beam as a different color, depending on what environment our brain is white balanced to.
using a camera to take pics is very informing. The trick is to get shots that actually look similar to what our eyes are seeing at the time. Some photos turn out better than others when showing colors. It depends on the light in the picture.
there is more info about tint, CRI, white balance, CCT
in the Tint Snob thread
