Color spaces, as ysap stated, can be a confusing issue. There isn't a single correct answer to this question, and what you intend to do with the "final copies" of your images will really dictate what color spaces you use and when you convert from one to the other. While I think it is getting a bit dated, sRGB is still the "safest" color space these days. ...

I've had exactly the same issue and it is possible to arrive at a correct and workable solution. There are a lot of misconceptions both in the question and the previous answers (and indeed, around colour management in general), so let me try to clear them up and provide you with an answer. First, the misconceptions... Regular (non-wide) monitors do not ...

Gamut and color count are not really the same thing, although a low bit depth will start to affect gamut to a degree (i.e. a 6-bit flat panel will never be wide gamut, simply because its sampling of the color space is too sparse.) Gamut describes the range of colors, from the total L*a*b* space, that a monitor is capable of representing. Many monitors are ...

Yes - you need to calibrate your monitor. One option, which is what I did, is to buy a relatively cheap colorimeter, at the time the Huey Pro was generally available. I used it as a travel colorimeter. Later, when I wasn't traveling as much, I bought a more expensive colorimeter (Lacie Blue-Eye Pro) for my home IPS monitor. I found that the cheaper ...

First, one need not spend $10,000 on a printer to get a wide gamut. To be specific, to PRINT wide gamut, you don't need to spend a lot of money. There is often an implicit association between managing color and printing wide gamut, however the two are actually separate activities. These days, the actual process of managing color is automated by ICM, which ...

Well, if you want to be able to work in a gamut, you do need to be able to display it, but it doesn't cost $2000 to get a monitor with AdobeRGB support. I use an HP LP2475w as my main monitor and it is able to support AdobeRGB fine and was only $650 when I got it several years ago. You also need a color calibration unit, of which there are many options, ...

I'd say that it depends on your output medium, or more correctly, the relationship between the object, the storage format and the output medium. The problem is that when working with an extended space, then at the last stage of actually printing or displaying your image, where the medium is more limited than the source, some kind of remapping needs to take ...

I would say that a wide-gamut display is NOT really necessary if you only intend to publish to the web. As you know, sRGB is pretty much the lowest common denominator for presentation on the web. Unless you expect the majority of your viewers to be using color-managed web browsers capable of properly rendering images tagged with AdobeRGB, there aren't really ...

First, yours won't work well. From the NEC FAQ: Why are the Spyder color sensors not recommended for use with wide color gamut displays such as the LCD2690WUXi, LCD2690WUXi2, LCD3090WQXi, P221W, PA241W, PA271W and PA301W models? Our evaluation of these devices has determined that the accuracy of measurements when used with wide color gamut displays ...

This is probably a similar question to this one: Lightroom exports are too dark in Flickr. I have two wide-gamut displays (desktop, laptop). You may want to give newer versions of Firefox a try, but I wouldn't hold my breath. A year ago I went back & forth reporting this issue in the Firefox bug tracker (issue 497363 and 509710). Color management in ...

16.7 millions colors is one way of describing a 24-bit monitor. It is capable of displaying each of the three colors used to produce all color on your monitor in 8-bits. That means it can display 256 levels of red, 256 levels of green. and 256 levels of blue. Thus, the total number of possible combinations is 256*256*256 = 256^3 = 16,777,216. That doesn't ...

Why do you think your Macbook or IPhone & IPad has the calibrated screens or why are you trying to achieve those colors. As you have adequately put, you have did your research and bought the "best out of box color calibration and overall reviews for its class". Regarding your question, firstly you should use DVI, HDMI or even better DisplayPort port of ...

Comparing colors from any single uncalibrated display to any other uncalibrated display or print process will cause you all kinds of problems. It's best to begin to get all of your color processes calibrated. Then compare them under good light, meaning the same light you have set the white point of every color calibrated display. So if that is D50 then ...

As a photographer that prints regularly in a gamut much larger that his display space, I can tell you it's possible, with the complete understanding that your blind in some image areas on the image you will actually print. Even a monitor slightly larger than Adobe 1998 can not provide the coverage a high gamut process can. So this is the method I use: ...

You can read extensive revies and tests of gamut coverage, viewing angles, fitnees for photo work , etc. here: http://www.tftcentral.co.uk/reviews.htm Doing a quick search on the review page for "wide" you can get to some wide gamut options quickly. There is a Selector tool where you can input that you need a wide gamut for photo work: ...

The real key is going to be that you'll want true 8 bit color resolution rather than the 6 bits that most TN panels get. Off angle color changes is also a key issue when looking at choosing a good screen for any color sensitive work. Having a wider color gamut is helpful, but if I had to choose between a more limited color gamut on a S-IPS panel with good ...

I had also the same problem and tried following sensors: Spyder 4: spectraview profiler detectet also for calibration the Spyder 4 and did the job with an inconsistent result and with a high difference of Delta values. And, some times the calibration failed. i1 Display pro: After that I used a i1 Diplay pro and get the best and constant results for Deltas, ...

Laser printers are not really known for their photo print quality or gamut. Ink jet printers have completely dominated this arena, and currently offer far wider print gamuts than you can get from other print technologies (especially from Epson and Canon). Current ink jet printers using UltraChrome HDR or Lucia EX support wide gamut up to Adobe RGB area, and ...

Printerinfo.com seem to measure gamut in their printer reviews. For example they say the HP CLJ3600n "is not meant to print photographs, and this clearly shows."

Modern versions of Firefox have a setting to try and manage non-profiled images as well as profiled ones. You can go into about:config and alter gfx.color_management.mode to '1'. (The default is 2.) A bit of Googling might yield a better explanation, but it has helped me when viewing SmugMug thumbnails, etc. It's still not a system-wide fix for Win7 ...
