Aside from all the good advice given until now, I wish to say some thoughts that hasn’t been mentioned yet, or which are my own preferences:
- as already said, you can’t go wrong with NEC or EIZO, you will pay more for them, but you will for sure get what you pay for. And just to check prices, take a look at this Spanish online store. They send items to Europe, although you will have to add the shipping&handling costs, obviously
- I wouldn’t be obsessed by embedded hardware profiling solutions, and if I found a display without hardware sensors or software, but with the gamut I need, I would buy it without hesitation (for professional photography, I wouldn’t go for less than 99% AdobeRGB)
- don’t forget that color management is not just about having a good display: you absolutely need to start with a good profile for your camera, follow it with a good and properly calibrated display, and end up with a good and calibrated printer. In this sense the i1 Display Pro, even though really good for displays, is useless to calibrate a printer, so you will need another device (and professional quality ones may cost you even more than the display)
- I’ve recently found that creating images for the web is not necessarily an straight conversion between profiles. You will have to check it for yourself, but it’s worth reading that thread to prevent possible surprises. I’m even thinking about having 2 profiles: one that takes into account the capabilities of my display and the ambient lighting, and another one just to work for the web
- about ambient lighting, if you have a device capable of measuring ambient lighting (like the i1 Display Pro), most probably you will only have to take care about choosing some lighting with a Color Rendering Index (CRI) of 90 at least (95 CRI would be even better). A cheap led lamp with near 6000ºK, may be enough. Then just let the profiling device to measure the color and intensity of your lighting and adjust the display profile for that
- remember that with professional color, you can’t be in a hurry when cold starting both the display and the ambient lighting (that is, when they have been turned off for several hours): they need to heat and stabilize before being sure that you get the right colors
Well, just a few thoughts
