Didn’t take it as argumentative, no sweat! I’m sure my vision will catch up with my elders’ soon enough lol. Already at the point of increasing text size on all my devices :weary:
Do you know what an argumentum ad ignorantiam is? If not, look it up. It’s fun.
And so it actually is tied to an individual. Each user has its own TCR. Ok, but[sic] this value already exists. You often read it in reviews, sometimes along with the raw numbers, in terms of “warm”, “greenish”, “angry blue”, “nice color rendering” and so on. I like to read how everyone feels about a light, but take it with a grain of salt.
“Nope. I have preferences just like anyone else, but I don’t think assigning numbers to them and discounting any of the quantifiable factors when possible is the best choice.”
Show us where I’ve specifically discounted any of the quantifiable factors when possible is the best choice?
Does not the person who is aware of a TCR rating have the perogative to compare it to CRI or other like standards? At that point shouldn’t they decide whether to give the appropriate weighting of CRI over TCR? Why should I be required to educate them on CRI to help them determine the validity or invalidity of a TCR rating?
Again, CRI isn’t meant to be supplanted by TCR. Not partially, not entirely.
Unless I’m misreading, you make it sound as if that’s factually supported by my direct words. If I gave that impression somewhere just discount it as an inadvertent oversight.
Yes. Was it that? Yes, I was trying to be persuasive by over-kill but not abnormally so. :laughing: (And I was also being a bit rhetorical and perhaps even slightly sarcastic).
Now……
“And so it actually is tied to an individual. Each user has its own TCR. Ok, but[sic] this value already exists.”
Yes individuals are inherently subjective hence TCR is inherently subjective.
The problem with “this value” is that it’s too loosey-goosey in terms of a mere word or combination of words like “angry blue”. And I believe correct me if I’m wrong, you’re mainly referring to tints here; not comparisons to specific color renditions one knows on a familiar object while in sunlight vs the accuracy of those same colors as they see them from a flash at night.
Of course defining watt “sunlight” is and watt “night” is can get ridiculous. So let’s just say for example, “Decent Sunlight is around 12:00 noon, cloudless, and Decent Darkness is around 9pm, smallish moon. We all mostly know watt those two terms mean when it comes to flashes and prolly most would automatically do it for the most part that way anyway.
So a number rating of subjective comparative observations becomes TCR. If I give a particular flash a TCR rating of 8 that would mean that a familiar object per the above parameters color-renditions quite well at night. I have flashes that I wouldn’t give a 3 to becuz they fail at showing reds, yellows, and blues no where near their renditions in decent sunlight. Coincidentally if these 3 primary colors fail to rendition well at night, then the secondary and subsequent tertiary colors likely won’t either.
Read in my signature the simplified definition of TCR. Notice the word, ‘sunlight’. That right there is a TCR parameter that helps narrow down this loosey-gooseyness.
Now lay off the Jagermeister. It’s getting late for me, I’m tired, and you’re talking like a German. :laughing: :+1:
There is no objective measurement for this so-called standard so it’s useless.
What’s great is if someone tells me CRI, R9, CCT, and duv I know exactly how it’s gonna look. I’ve learned what I like from those measurements and can appropriately choose, sight unseen.
CRI, had a learning curve, but not at all onerous. Plus, it is based on science, not a personal perception of what looks good to a bunch of humans who … well are human and have personal preferences which influence their choices, for everything, not just lighting and perceived colors.
Plus, we shouldn’t be arguing so I have nothing more to say on this
Well I suggest from now on if someone asks for your opinion (purely subjective) on a particular flash you should answer,……
“I don’t have an opinion worthwhile to listen to. Look up the manufacturer’s CRI, etc., on that model. After all Bub, I’m just another human like you and the science here is all that matters.”
I think Whacky presented nothing to argue about . He had an idea, told us about it, and defended it. I find it ad hoc useless, but want to see where this thread is going. E.g., there are lots of interesting posts [from others ].
Watt? C’mon man don’t give me a Rommel Panzer retreat from a Patton deal here. :laughing:
TCR it for me.
Take the most familiar object you likely know typically in yer right hand; go out in the sunlight prolly tomorrow if today is too late. Note the colors. Then compare them to the flash rendition.
Do the pinks and purples for example compare favorably/unfavorably? That’s the TCR rating.
