Re: Black Widow - How does it calibrate?

quite abit to digest there. i really would like to calibrate my projector with the equipment you have.

i can feel myself wanting to acquire an eye-one pro.
whats holding me back is that a new one is gonna cost me more than my projector

Re: Black Widow - How does it calibrate?

I'd think 'munki' first. I beleive those are supported by CalMAN. And if that's out of the realm go with the eye-one display2. They're colorimeters which will do just as well as the eye-one pro and not break the bank. There's also the Chroma 5 colorimeter which is also available at SpectraCal.

The cheapest way though would be to buy a Display2 and run it with HCFR.

That would the Colormunki Create by the way. There is a difference. The Colormunki Photo has uv filters.

Re: Black Widow - How does it calibrate?

on the subject of colorimeters and their method of measuring.
i always thought that the use of color filters would limit the accuracy of the colorimeter over a spectrophotometer.

i reallly need to to carry out some calibration on my projector as i have noticed that some of the gray bars on test patterns i use have a slight hue to them.

i may just pick up an eye-one display for now.

Re: Black Widow - How does it calibrate?

For doing this type of calibration all that is needed is R, G and B sensors (Tristimulus values).

Here is the link for HCFR http://www.homecinema-fr.com/colorimetre/index_en.php

Re: Black Widow - How does it calibrate?

Yep you could build one as well. Smokey Joe built one and used it for awhile before giving it up for his eye-one pro.

Hey! They have a new version out. I was running 2.01. I'm gonna have to check it out. I've also been doing more reading in CalMAN. Turns out I can do much better charts than what I have been using.

Re: Black Widow - How does it calibrate?

Talking about i1pro or cheaper alternatives, how about Spyder3 elite? How does that compare to i1pro, i1- LT, munki etc?

Mechman - I have been looking at the spectro raw numbers from the link under your posts. I do not see BW listed there for comparison. Is this on purpose?

I'm sure Mech has more info on the units you mentioned, but he is away from the forum for awhile, it's hunting season in his neck of the woods.

The Spyder3 Elite is not a spectrophotometer, but rather a colorimeter. The difference is that a spectrophotometer can measure the full visible spectrum while a colorimeter can only read colorimetric data (not full spectrum). A colorimeter is fine for many uses such as calibrating imaging devices and gathering RGB data, but for truly defining and matching colors a spectrophotometer is desired.

The list that Mech links to is quite old now, it was made while BW™ was still in the development stage. I believe "Dice" and "Poker" were early metallic paints in BW™ development. All the data for BW™ is in the BW™ presentation thread, but I'll copy them here as well.

The final spectro numbers for this mix are this:

RGB: 186 186 186

L*a*b*: 75.5 -0.06 -0.08

Which according to the Lindbloom color calculator gives a screen temperature color of 6503!
