| Is your monitor calibrated properly? Did you ever
calibrate it? Or if you did, how long ago? But even if
you did calibrate it with special software, how do you
know it was working properly? Monitor calibration is the most fundamental issue to successful photo color correction. Unless and until this critical foundation is set correctly, everything you attempt to build on it will be suspect. Every single image you edit in Photoshop will not have correct color (except by accident). So how do you know if your monitor is displaying colors accurately? gretagmacbeth offers a ColorChecker Rendition Chart that photographers everywhere use to check color accuracy. It's a plastic card about 8 x 10" with the colors you see above. Buy one so you can compare it to your monitor. That will show you if you need to get monitor calibration hardware and software, or if you already have it, whether you need to recalibrate. (Of course it can also let you know if your assumption that the calibration hardware and/or software works properly is correct.) How accurate is the online chart above? gretagmacbeth's chart comes with a mini booklet which includes the RGB values for each of the block colors in the chart. These were put into the html editor used to make this webpage exactly. The red block of color, according to the booklet, has these RGB values: R: 175
Note: Using the above industry standard color chart compared to the original plastic card version may more accurately reveal whether your internet browser is not displaying accurate color, as opposed to your monitor. Your monitor could in fact be correct, but the browser is inaccurate. |
