We received a lot of questions and as promised, here is a Q&A covering all the questions I could understand! (some questions had to much slang and shorts for me to understand)

If your question was not answered, please feel free to send me an email!

Here we go:

Q: If you have a built-in calibration tool as in some Eizos do you still need an external tool to calibrate for some reason?
A: No, If you have a monitor such as the Eizo CG245 you do not need any additional hardware. But keep in mind that you can not use the built-in calibrator to calibrate other monitors such as you laptop(of course).

Q: How is it possible the D3X working in Adobe RGB color space exceeds this space’s borders?
A: When shooting in raw mode, your files have no dedicated colorspace. The raw files from a Nikon D3X or a Canon 5Dm2 holds more color information than the Adobe 1998 color space can hold. By choosing Adobe RGB as you color space when pixelating you images, means your “cutting” away information. If (but why would you) you shoot in Jpeg mode, the camera attaches a color space for you (Adobe RGB or sRGB) and the above information does not count.

Q: Your microphone gives away scratchy noise
A: No it doesn’t… Its my voice your hearing…

Q: When the camera only has Adobe 1998, is converting to ProPhoto useful? Data is not direct available so it is calculated?
A: If you shoot in Jpeg, then there is no point in converting to ProPhoto.
Not only will you not gain more information but you will most likely mess up some of the color information.
When you shoot in raw, the color space settings for your camera is disregarded as that is set during post production.

Q: Which is better, i1Display pro or ColorMunki for calibrating Monitors?
A: The new i1Display Pro is a colorimeter, it can only calibrate monitors and projectors. The ColorMunki is a spectrophotometer and can in addition to calibrate monitors and projectors also create print profiles.
If you don’t need the option to create print profiles, I personally would go for the i1DisplayPro.

Q: Can you really calibrate a laptop?
A: Of course you can. You’re however limited to the color space and quality of that specific laptop monitor, which are rarely any good.
Most laptops can only produce 6bit of color but simulates 8bit.
There are laptops that have true 8bit monitors, and larger than the sRGB color space, but I would never use one for critical color managament.

Q: Basic question: do I need to caliberate my iMac monitor more than once? I caliberated my monitor a few months ago using my colour munki but never done it since. is this ok?
A: When working on a hardware calibrated monitor such as the ColorEdge series from Eizo or the Reference series from NEC its recommended you calibrate your monitor every 200 hours.
When working on a non-hardware calibrated monitor such as iMacs, laptops etc, I would recommend that you re-calibrate every two weeks.

Q: What Color Space should I use in my Nikon D3 and which Color Space on Photoshop CS5?
A: Set your camera to Adobe RGB, but remember that this does not matter when you shoot in raw.
I personally have set the working color space in Photoshop to ProPhoto RGB which is also photoshop’s native color space.

Q: What’s you advice to calibrate a Eizo CE240W, use the Eizo ColorNavigator or the dedicated sofware of X-rite?
A: If you have a monitor which can be hardware calibrated, then you should always use the dedicated software that was provided with your monitor.

Q: When needing to convert an image from Adobe RGB to Pro Photo RGB, is it as simple as converting it in PS, or does it mean one has to re-edit the colors in the image again?
A: You should never convert any image from Adobe RGB to ProPhoto RGB.

Q: When will xRite be ready with Lion support for the i1Display LT product?
A: New software should be arriving in September sometime…

Q: what is “native” whitepoint? just because my monitor says 6500K, without an instrument, how will i know it i really 6500K ….espec. after day 165…
A: Native whitepoint is where the whitepoint is naturally set from factory.
This could be 6500K 6389K or any other number. Most monitor makes try to get as close to 6500k as possible.
You can not really be sure what your whitpoint is at, without calibrating your monitor.

Q: If you are going to print your photo you translate it to CMYK and CMYK colorspace is more narrow than RGB, why do you need to use a big colorspace like ProPhoto RGB? Because the paper you print on can´t show so many colors?
A: No you do not. I would still argue that is it better to do so as a safe guard. What if you later on decided to print your image on a Epson inkjet with a way larger color space than CMYK?

Q: I have a wide gamut monitor which can simulate sRGB and AdobeRGB. If I edit sRGB images, should I set the monitor to sRGB before calibration?
A: If your going to use a simulated color space then you should create a specific profile for that space. As you suggested, set your monitor to simulate sRGB calibrate your monitor and switch to this new profile(in your computers OS) every time you simulate sRGB.

Q: Hello, I am working on an iMac 27″ and, as you might know, the monitor does not allow adjustments… so, my question is if the iProfiler can be used to calibrate an iMac
A: The new i1Display Pro is perfect for you. With its new ADC the software takes care of everything for you and adjusts the luminance automatically for you(it does this with all macs and most external monitors that have a USB uplink).
