    BTW on the x-rite site I found this interesting test:
    http://www.xrite.com/online-color-test-challenge
    Quote: "How well do you see color? FACT: 1 out of 255 women and 1 out of 12 men have some form of color vision deficiency.."
    My result was 12 (range 0 - 100, less is better), seems to be not so bad for a male beyond 50 years of age...I found no recommendation at which result a colorimeter is needed..or maybe useless :eek:

    To get a perfect score of no errors you need both a good colour vision and a good monitor, properly adjusted.

    I have an HP w2448hc for my desktop computer. I like this HP monitor even if it is starting to show signs of age. It produces colours that are very close to what I get from a Canon PGI-5/CLI-8 printer with IS inks.

    I also have a laptop, Medion Akoya E6214 bought from Aldi. This laptop uses an LED panel backlight, probably to extend battery time. But the screen has very dull reds and even if I tweak the colour settings, the reds are no good and the image is too blue-ish. The laptop is no good for photo work.

    Here are my results of the on-line colour test. Top is the HP monitor and bottom is the laptop. I would have expected the errors were in the reds but they are in the blue/green for the laptop display.

    O.k., quite interesting, but please be aware that results of this test very much depend on the monitor brightness, the color temp/white setting, and as well of the lighting conditions around the monitor

    I'm aware only of a few of those programs - Gamutvision, ColorThink/Pro. Some of such analyzing capability is part of profiling packages by XRite or basiccolor or.., but those modules are not available as stand alone programs. I'm not aware of a open source program with equivalent functions

    "Please expand your thoughts as I was not expecting that as a response as I am pretty sure not everyone that uses Gamutvision etc. use an Argylle type product?"

    Probably not, but some like spending money on the latest gadgets.

    Canon were, BUT 3D is better..
    The last time I fiddled around with this colour test I scored somewhere in and about 40 something and taught that’s about right, because I reckoned my old pork pies were not as good as they used to be, Huh see what I know. :confused:

    Well I tried again and this is what I scored, I reckon I must have cheated somewhere because all I done different this time was to turn out the florescent light about my head.. :hu

    Yes agree entirely. However, my curiosity is in overdrive at the moment, I have been doing profiling in the belief that it was giving me the best results possible.......from what is being said, and the links being posted it seems to be that "it 'aint necessarily so"!!!

    I was looking to the folks that are currently using this software to input so that I could at least start my search in roughly the right area. Being lazy I would rather look in the right places from the get go:caf

    the first and important aim of profiling is the standardization of color output across different devices/printers/displays, media/papers, inks , driver settings, viewing conditions and more, and the first step is measuring the situation before that step, and then appying corrections to acheive that goal. You are inherently confronted with limitaions in that process - the contrast range of the paper, ink and saturation limits etc, so lots of users are trying to 'optimize' that process for which you need some tools to identify possible 'weak' areas. There was another thread a few months ago discussing the intention to use a profile to tune print output to a particular look, that goes beyond and against the job of profiling to standardize color output in my opinion. There are different levels of engagement with profiling - you use OEM inks and papers and the profiles of your printer manfucturer , you can get profiles via a 3rd party provider for your own paper/ink combinations, you use their profiles as is, you get a profiling package for yourself and do it for yourself, you experiment and test some other papers, other inks, software settings and compare, you look into more detail to the print results, and you want to know more, then you go for Gamutvision etc. It all depends how much interest and time you have for that subject, or you rather go off and take more pictures or spend your time (and money) for something totally different. That's like always with a hobby - you define the level of your engagement with that subject.
