True Color Rendition (TCR)..........

In Post #56 you state……

“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.

Just clearing stuff up again for the record.

Yes. Was it that? Yes, I was trying to be persuasive by over-kill but not abnormally so. :laughing: :open_mouth: (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: :open_mouth: :+1: :beer:

I give the dedomed Ti3 a TCR rating of 2.5. I give the Mini2 a TCR rating of 9!

If we average our data sets, we get a mean TCR of 5.5 for the Ti3, and 7 for the Mini2. We now know that the Mini2 is clearly the better light!

Really, that low on the dedomed Ti3? Was it in NW from ThruNite?

Assuming yer being serious could ya ask somebody to give their TCR?

Btw are you using decent sunlight as a baseline for the comparisons?

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.

Where does it say it’s supposed to be a standard like CRI?

It’s a subjective rating system better supported by hopefully consensus.

You could use it with CRI,R9,CCT,duv, etc., butt since yer already happy that’s all that matters. You.

Btw it took awhile for you to really learn it, right? How many flashes later? Was it useless before that?

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 :slight_smile: . 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 :smiling_imp: ].

:wink:

Aren’t ya hittin’ the Jager kinda late even for U? :laughing: :open_mouth:

Oh, I can be the BLF idiot without alcohol (actually I’m abstinent).

You like Jägermeister?

Hell no. That sheeeeiiiiiiitttttt is too dangerous. :open_mouth: :beer: (only)

I think it stays in yer system so long that a year later you can get a DUI. :laughing:

PS. BTW watts the TCR on that mini whatever yer holdin’ in your hand? Is it a dedomed Mini3?

At least ;).

You mean the TrustFire L1? Scroll down to the last posting and … read :smiley:

Ya know ya got a knack fer gettin me to buy things ya like. I like the looks of this mainly cuz of the button.

Just to humor me before I spring out the $$$$ cood ya give me a TCR on it? :laughing: :laughing: :laughing: :laughing: :open_mouth:

Same LED in the Minis and the L1. You gave it a 5, I’ll give it a CRI 75 and an angry blue.

Watt? C’mon man don’t give me a Rommel Panzer retreat from a Patton deal here. :laughing: :open_mouth:

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.

7.5

What a coincidence that it’s CRI 75! :smiley:

Seriously, after my eyes did their balancing trick, the colors look ok. Like CRI 75 TCR 7.5

It’s still angry blue in the center (8000K+), has a yellow corona just below 5000K and spill around 6000K. Your TCR won’t tell you this.

No butt the TCR succinctly and quickly did without going into your other details.

I now know that this flash with a TCR 7.5 prolly ain’t gonna cut it for me. Butt your’s is just one TCR opinion. I’d like to hear others. Consensus is better. Cuz ya know every flash is different.

Ok. Maybe I’ll get it anyway cuz yer German and Blaupunkt is proof that specs don’t mean everything. :laughing: :open_mouth:

PS. Same thing goes for Pukas, ooops I mean Lucas. :open_mouth:

Don’t. It’s got exactly the same LED/optics like your Mini2 has. You gain nothing except that button and AAA compatibility.

But if you know how to mod it to a shaved SST-20, you’ll give it a 10.

Well ya know how much I like the Mini2’s general construction - that spectacular spill particularly.

Can ya change the optics? Maybe one with a built-in higher CRI? :laughing: :+1: :beer:
