Calibrating a Monitor
Okay now let's look at monitor calibration and let's look at this ISO standard that we talked about earlier - let's have a look at that. So ISO 3664 standard calibration and what is it? Okay, basically says that your the brightness of your monitor, or if you like your gamma okay? Is... Sorry not your gamma - your brightness on your monitor is set to 120 candela per meter squared. Okay, these are the parameters that we'll put into the software in a minute as we calibrate the monitor okay? The white point is set at D65 okay? Or you know 6500 kelvin okay? And the gamma sits at 2.2 or Native. Now with these type of monitors, okay, the ISO's, what I can do is drop that white that minimum luminesce right down to 80 candela per meter squared because you know usually you've got average lighting of say around 400 lux reflecting off white paper, which visually approximate, calibrated, you're looking at a level of 80 candela. Okay so, I wouldn't recommend you go down to 80 candela on something li...
ke an Apple or a glossy screen because of the contrast that they give you - you will see no shadow detail whatsoever. You know the high-end monitors will be able to do that. Otherwise, 120 to 100 candela. Remember that if your screen is too bright, your prints will be too dark okay? And if your screen is too dark, your prints will be too light. So try and go to a low luminesce level on something like a glossy screen, like an Apple screen. What happens is you'll think you'll have no shadow detail so you start to increase the brightness. By the time you print it, it's gonna look overly bright okay? So it is a balance of what you, what you set your points to. As far as monitor calibration there's a few things on the market. One is the ColorMunki Photo which does not only screens but you can also write paper profiles with which we're gonna do that tomorrow with the ColorMunki Photo. But the simplest one is the ColorMunki Display which is this one here, which is just a nice little one that I travel with just to keep my Macbook Pro here in check okay, which is very very important. Okay so what we'll do now we'll do a live monitor calibration first using this device which is the ColorMunki Display, and then we'll do a hardware calibration on the ISO using the built-in software that's already in there. So, let's move a few things around and we'll get started. Okay so now we'll place the device onto the screen like so, making sure that we have a nice, beautiful contact around the sides and we don't have any lights spilling in. So the screen has to be tilted far enough so that we're not getting light spillage through. And then very simply we hit next and we let we let the software do its thing. Okay so it's gonna do a couple of measurements. Okay so now it's measuring colors, all the different colors. We've measured the brightness and we set that based upon the parameters that we set in the software, and now it's going through all the colors and setting the profile with the right color. Okay so once the calibrator is finished we just remove it off the screen, and over here up on top we're gonna give it a significant name. Okay so, you know it comes up with this number which is kind of a little bit long, so what we do is you know, we would take that out and put it to today's date so that we know that that was the last time we calibrated, and we hit Save, and automatically the software will install the profile exactly where it needs to go. Profile complete. Then it asks you here, "Remind me to re-profile this by every week, every two weeks." Usually every two weeks is a safe bet; that's what I would recommend. And then we hit next, and we can do a before and after comparison. Before which is we're getting this blueish tinge, and then after, the properly calibrated monitor. And of course we can test it only with a bride but we can look at black and white flowers. So before, after, and a colorful image - before, after - and we can just see how the calibration has worked to create the profile that's going to manage color on our screen.
