Okay, your first step for controlled accurate soft proofing is controlling your viewing environment. The second step is calibrating your monitor. Calibration of the monitor is done with an ICC profile.
Okay. The way an ICC profile works is, let’s just say you have a digital file. Our digital files are RGB that we shoot as photographers. RGB means that there’s every pixel has red, green, blue information. A white, gray or black is equal amount of red, green and blue. So, we’re going to go at 80% gray which is 128 red, 128 green, 128 blue. What we’re going to do is we’re going to take a digital file that is composed of equal amounts of red, green and blue. It’s a pure gray and we’re going to take that digital file off to hard drive and open it up into the monitor.
We took two monitors made by the same manufacturing the same day and display those, there will slight differences. Well how would are computer know how that monitor is displaying in this or some way to read the actual color that’s been displayed off the monitor.
So, what we do is we take a color spectrophotometer. It’s a device that actually can read the color of the monitor and we read what color that actually was displayed and let’s just say for instance the monitor was a little bit red and so instead of being 128 red, its 140 red, 128 green, 128 blue. It’s how red bias to it.
The spectrophotometer would sense that and then the profile would be like putting a filter in front of the monitor and it would remove that red when I display the image. So the profile not only mix it from the gray, it does it from 3000 different color. It displays 3000 different colors in the screen, reads them in spectrophotometer and then the profile makes that for any indifferences or inadequacies of that monitor.
Okay, here we go. We’re going to do some eye one match 3. We’re going to build a profile using eye one tool. We’re going to first show you how to use the easy feature when you open eye one it ask you, do you want to build the monitor, projector, scanner, printer or camera profile. We selected monitor and I’m going to choose easy.
When you would use easy profile is if you only have control viewing conditions, if your viewing ambient conditions, mix light conditions and your really haven’t taken control of your viewing conditions and you don’t expect it really help tight built a tolerance match then you can use the easy mode. That’s the mode that I use when costumers never taking the time to make a good viewing conditions and having a really tight tolerance is an important work factor to them.
So, in this easy mode, what we going to do is the easy modes does just everything automated in the software. You don’t choose a white point. You’re not balancing the match of viewing both and your whole goal is just to get a calibrated monitor. It does it at 6500 Kelvin is what it makes the white point of your monitor. It does not let you adjust the red, green, blue guns and it does not allow you to adjust the luminance of your monitor, okay.
So, what we’ve done is we’ve got taking the eye one, plug it into USB into the computer. We’ve set the eye one on its calibration path, its match to that eye one and it’s a simple as hitting the next arrow for the next step. And then, we tell it, isn't it an LCD. Isn't it a CRT or is it a laptop. We calibrate the laptop on this picture it’s saying put the eye one on your calibration disk, hit the calibrate button. Can you see it’s calibrating? It was successful, hit the next step, it says, place the eye one on your monitor. This particular the device here is the LCD holder for your eye one, slide that on, set that on your monitor, we’ll lean it back just a little bit for it if you don’t want pressing a key and we don’t want to.
Okay, we hit the next arrow. Now, what it’s doing is its flashing of white and a gray that’s determining the location of the eye one because you can calibrate using the center, the right-left, you can then calibrate to any area on the scree. It’s determining the exact place anywhere it is. It’s now measuring the color temperature of your monitor and this is doing the procedure that’s telling you about –the simple definition is it displays a gray and knows exact lab color of that gray. And then it compares but it’s actually reading it. It knows the lab color of every color that its displaying and then it compares the actual color with the monitor display. The profile makes up for any of those—
