Okay Folks. Here's the deal. I'm really tired of seeing eight zillion different screen setups being used to post prints because when everyone has thier own wacky standard then *nobody* ends up producing art work the same way. So I'm taking the initiative and implementing a little standardization here.
Here's how my chart works: Simply use your monitor adjustments, wherever they are (on the monitor, from software within your computer for your video card, whatever) to change you CRT monitor (aka, NOT FLATSCREEN) so that the following things happen:
1. The middle bars, or Zone Steps, indicate the nine step transition from screen black (not TRUE BLACK) to pure white -1 (NOT SCREEN WHITE). The darkest bar or "I" should appear as black as your screen can go. The lightest bar, or "X" should appear SLIGHTLY LESS WHITE THAN THE SURROUNDING WHITE BACKGROUND. If the two appear completely the same, then there is a problem with your monitor calibation. I've included the means to fix it. Go to step two.
2. The lower left hand box is the black calibration box. You should adjust your monitor so that the gradient within it can be seen but only enough so that it appears to vanish into the surrounding blacks between 1/3 and 1/2 from the left to the middle of the box.
3. The lower right hand box is the white calibration box. You should adjust your monitor so that there is a difference between the two inner boxes and the outer one, but only enough so that they do not blend completely together. The middle box is SCREEN WHITE.
4. Make sure your monitor is set to millions/billions/trillions of colors or else every photo you look at will have a compressed colorspace. To check and see if yours is set to it's highest rez, look at the COLOR grad in the middle of the chart. If the upper one appears to have "banding" or doesn't look like a smooth transition from color to color (I provided an example of color stepping, which looks simiilar to banding), find your monitor's controls and change it to it's highest rez. If your monitor is old and crappy and can't display anything more than thousands of colors, buy a new one, they don't cost much, even a crappy millions+ monitor will be better than one that can't display a full RGB colorspace.
Once you've done this, go bounce around dA again and look at just how much freaking better (or worse) things look... it can be shocking. My goal is to keep people from MAKING poorly compressed work: under exposed or underprinted or flat work...
I'll do a whole explanation on this to anyone who wants to hear it.
(Technical Spec: bw grad at 11% intervals equiv. to 28.33/channel/step. Zone I @ 0 : 0 : 0 , Zone X @ 253 : 253 : 253. color grad at R : Y : G : C : B : M : R @ exactly (R : G : B) R= 255 : 0 : 0 , Y= 255 : 255 : 0 , G= 0 : 255 : 0 , C= 0 : 255 : 255 , B= 0 : 0 : 255 , M= 255 : 0 : 255 , R= 255 : 0 : 0 , ZoneI swatch @ L : a : b or H : S : B %'s 0 : 2 : 4 : 6 : 8 over 0, ZoneX+ swatch @ L : a : b or H : S : B %'s 95 : 97 : 100 with RGB center column grad equiv. to Zone X to Zone X+: 243/channel to 255/channel)
"Make sure your monitor is set to millions/billions/trillions of colors or else every photo you look at will have a compressed colorspace. To check and see if yours is set to it's highest rez"
Rez? If you're going to bash everyone for having "thier own wacky standard" then at least get things right in your tutorial. Resolution has nothing to do with colorspace. Its their monitor's bit depths, usually set within the operating system, not in the monitor, that could be too low. Low resolution doesn't cause posterization.
It's great that you post things like that. I put my laptop to a printing house and they calibrated it with a Macbeth so I hope it works okay now. Followed your test, but the results actually depend a lot on how I tilt the screen. Well, maybe someday i can afford a proper monitor
You have an LCD screen, which have narrow viewing angles (even on so-called "wide" viewing angle screens). Accurate color reproduction is often evaluated between 10º and 2º, depending upon manufacturer, and for many, it's purely subjective.
Moreover, because different manufacturers use different technologies (TN, etc) there's no "standard" in color. Usually it's recommendable to get a monitor with a high cdm2 value (measured, not advertised) if you do photo/etc. If you're a print graphics person, get a monitor that can produce the standard illuminant that you need (D50, etc).
Hey! Umm I just recently calibrated my monitor using spyder2 pro but when I look at the exif data on photo's that are different sizes or duotoned version etc. Some have have a colour profile of Adobe RGB (1998) and others have one saying sRGB IEC61966-2.1 is that normal?
Sorry for the long question xD
Yeah, typically a properly prepared image for web will be in sRGB, which is a color gamut suitable for display. Adobe RGB(1998) is used for images going to print. It depends on the content producer, for example, I shoot everything in 1998 because I work principally in print media. Most consumer cameras come preset to shoot in sRGB, because it's assumed that the user will look at them on a computer more often than printing them.
Oh okay thanks! But why when I put them onto my computer unedited in Adobe bridge it says their profile is sRGB IEC61966-2.1 and then when i edit them in photoshop and look at them in bridge again the edited files says its an adobe rgb (1998) profile? and also is their a way of converting the file from Adobe RGB(1998) to sRGB IEC61966-2.1? And vice a versa.
Eep Another long question

Color is nasty business.
Mine looks all ok from here from your guidelines so i hope others see it the same way
Sorry for the long question xD
