i just found this interesting review showing that at least spyder 3 colorimeters produced since mid-2009 might be more accurate than eye-one (at least those from the 2nd generation - eye-one 2 LT and the likes)!

Older (pre-2009) Spyder 3 units showed high unit-to-unit variability. All the ones we tested were manufactured mid-2009 and later.
source

and colormunki display might be worth adding to the FAQ, considering its apparently amazing price/accuracy-ratio. $170 for accuracy that according to the article is on par with the best colorimeters. they say the downside is that it's a lot slower.

If the colormunki gains more software support in terms of home theatre video calibration then it's one we'll look at. It's slow because it's a spectro (like the EyeOne Pro).

i think you're mixing some things up here... according to both that article and the x-rite website, it's like the following:

eye-one pro and colormunki photo: spectrophotometer
BUT...
i1display pro (not to confuse with all the other i1 pro hardware - which are all spectrophotometers) and colormunki display: colorimeter
(and actually - the black sensor error as it is demonstrated in the article also shows that)

"display" seems to be the keyword in most of these products in regards to whether they're colorimeters or not.

Ah yes! Sorry - there are two versions of the Colormunki.

IMHO, the Display 3 seems to be the most popular solution for enthusiasts. Very little added cost over the inexpensive Colormunki but performance that rivals the $3000+ Hubble in many ways.

that's the one that's referred to as "i1 display pro" in the article, isn't it? the third generation after that "eye-one display 2 (LT)", this one here? (i realize it's sold on curtpalme as well but is still named "eyeone display 3", which is exactly the name confusion i would like to clear up... Smile )

if you're anything like me though and you only wanted to spend an absolute maximum of $150 for a colorimeter and the $170 is already a decision you only make with clenched teeth, the thought of spending $250 is a bit absurd Wink

but another major thing that seems essential is that the colormunki display is not officially supported by anything other than x-rite's software. no basiccolor, coloreyes or whatever else one might already have or want to buy. i guess they want to sell i1 display pros and not colormunki displays...
but $250... considering this ridiculous restriction, i might simply go with a spyder after all. if x-rite insists on such an arbitrary restriction, their loss.

I'm confused as to what meters we're talking about. Wink

What we call the "Display 3" is officialky called the "i1 Display Pro III".
Not sure why Amazon just calls it the "i1 Display Pro".

If you're limited to the budget you mention, see my FAQ "WHich meter is right for me?" and go with one of the lower end meters. The ones I mention in the FAQ have the widest support (which is why I mention them).

The FAQ is here: http://www.curtpalme.com/forum/viewtopic.php?t=11436

well... thanks, but the whole point of this thread is actually the suggestion that updating the FAQ may be something that should be considered, because of the things described in the review by dry creek photo...

Again, the colormunki's have extremely limited support (as you mentioned). This is why it's not the FAQ. The FAQ I wrote is for home theatre calibration. Little software supports them.

I have no interest in spending time with a meter with limited HT calibration support. Sorry.

that of course makes sense... but what about the fact that the spyder3 that were released after mid-2009 are supposed to have lower unit variability than the eye-one display 2? the difference is quite considerable after all

I have no idea. That's one's person comment on one website.

you are kidding, right?

how many people who have tested about 10 units of any given colorimeter AND who have measured that accuracy with a spectroradiometer of a kind that does not appear to be available to consumers and who have written extensively about the whole process do you know?

if you really wish to discredit him, you may at least want to contact the companies he alleges to have had contact with and ask them whether they did actually provide him with the things he claims they helped him with. even though some companies might deny it because they didn't like what he found. at any rate, i find this attempt at discrediting either him or at least his article without providing reasons/evidence very questionable.

Well, I don't see why anyone would need to discredit him... The most positive comment regarding Sypder's reliability is that it's three times as bad as DTP-94...

"Datacolor appears to have solved the worst of the manufacturing inconsistency problems seen with older Spyder 3 Elite models. On average, the Spyder 3 is a good performer. We still have concerns about the level of variability measured between units — almost 3 times what the DTP-94 shows."

I am curious about his final comment:
"Alternatively, spectrophotometer measurements of the monitor white values can be used to tune colorimeter measurements, allowing the strengths of each instrument type to be combined. ArgyllCMS is the only package that provides this capability."

I was under the impression that ChromaPure also did exactly this. Perhaps its the method ChromaPure uses to accomplish this desired end that's not as innate a ArgyllCMS? I don't know, I haven't used either software packages, or any meters at all for that matter! I'm a NOOOOB! Just doing TONS of research right now, getting ready to make a purchase.

I'm not discrediting anyone. I have no idea who he is and do not know his website nor have I read what he wrote.

I simply said, that's one person's opinion. You may use the information they post any way you wish. I have no idea if it's factual or not nor do I have time or interest in fact checking what other websites write or say to disprove them or agree with them.

My experience has been with sellers who have sold hundreds if not thousands of units (not just 10) and have compared them to $10K+ pro grade meters such as the Jeti Specbos that we sell here: http://www.curtpalme.com/ChromaPure_JETI.shtm

You seem to have started this thread to get us here to fact check or back up what he says about Spyder 3 unit to unit variability. You seem to be wanting me to say "Yes, you should go buy an inexpensive Spyder 3 as they're much better now". I can't do that as I don't know if that's true. I also won't go through their article word by word and comment on their findings. He may be perfectly accurate, it may be wrong. I have no idea. I haven't read what he wrote.

I did read through his entire article, and for what it's worth from a Noobie, basically everything he says lines up with what I read here: http://www.curtpalme.com/forum/viewtopic.php?t=10457. At least, as far as my buying decisions are concerned (with the one aforementioned exception regarding ArgyllCMS). Of course, the only reason I could understand what was said in his article was because of the GREYSCALE & COLOUR CALIBRATION FOR DUMMIES thread. Smile

It does. ChromaPure allows for meter profiling.

That website (http://www.drycreekphoto.com/) seems to be a photography website. Photographers tend to use calibration software packages that create Windows/MAC software profiles only. The meter reads what the display is doing and creates offsets in software to compensate.

That's different than what we do with home theatre video calibration where we adjust the display directly. The author likely is just talking from one side of things, creating custom Windows/Mac profiles. Not really relevant for home theatre calibration since most of us do not use a PC or Mac to play back movies.

no, actually i just started this thread to share these fairly new findings with people, since at least i found them to be very interesting. especially because of the scope of the whole test.
i also figured that maybe your FAQ is partly outdated by now - but whether you would feel like that's worth looking into or not is of course up to you.
i just have to say about that that i've always considered curt palme as THE resource when it comes to home theater, so when i present some facts that may be worth checking out and you don't even consider them worth looking at, i of course can't help but start to wonder what other things people may have brought up that were ignored...

at any rate... i haven't seen my CRT projector in over a year now, am using my computer for all media i consume and once OLED displays are standard, there'll probably be even less reason for me to look up things here. so... it's not for my benefit. make of it what you will, i just posted this to help people out, possibly shed some new light on the issue - i didn't expect such resistance... if anything, i figured it would just be ignored... (the clarification about the colormunki was important though and will surely be appreciated by others who stumble across it and initially think they've found a colorimeter with great price/performance ratio)

Sorry if I misinterpreted your original post.

It may be true that Spyder 3 units have gotten better over the years. The issue is that we're not really in a position to check this as we don't deal in them anymore as there's little interest in them for our readers, probably because prices of meters have dropped significantly over the years.

We're simply not seeing much interest at all from our readers in the low end display 2/LT or Spyder meters anymore. Probably because something substantially better (like the new Display 3) can be had for only about $100 more so they tend to go for that instead.

By all means if people want to comment on their own Display 2/LT or Spyder meters and how they compare to reference meters then they can certainly post their findings here.
