Reading Bill Peppas' here on Fstoppers got me thinking about calibration again. For the most part, it's a fairly simple process to improve the accuracy of colors on your display. A good many of us simply need to invest in a or system and allow it to do its job. Correctly calibrating a monitor with a hardware Look-Up Table (LUT) is a little more involved, and I wanted to share the procedure for calibrating a Dell Monitor with the X-Rite i1 Display Pro. O ver the past fe w years, Dell has released a series of wide-gamut monitors (//) with hardware LUTs that provide more affordable solutions to offerings from the likes of Eizo. Hardware LUTs offer greater colour accuracy, but require specialized calibration tools in order to make the most of them.
It's important to make sure that your monitor properly calibrated. Discover how to calibrate your monitor's software and hardware. The Ultimate Screen Calibration Guide. Actually we're not calibrating display ONLY but creating display profile so both hardware and software can show.
In the case of Dell's monitors, this means using their software and an (the only compatible tool). With this combination, calibration is able to be written into the monitor's LUT for the most accurate color reproduction possible. I recently took advantage of a sale on the i1 Display Pro, as until recently, I had been calibrating using a regular Spyder 4 Pro for ICC profiling. I had known this was not as accurate as it could have been, but after having to deal with a recent camera failure, I wasn't ready to spend the extra money just yet. When the i1 Display Pro arrived, I eagerly took it out and began the process immediately. However, I ran into problem after problem with the calibration and so decided to put together this guide for calibrating these monitors on Windows. Step 1: Preparing the OS Before calibrating your monitor's hardware LUT, you will need to remove any existing software calibrations (ICC profiles) and calibration software.
Calibration software can be removed using the Windows Add/Remove Programs dialog, and custom ICC profiles can be removed in the Color Management dialog. You will also want to check “Use Windows Display Calibration” in the advanced tab of Color Management. As Windows loads ICC profiles automatically into the graphics card on startup, you'll also need to restart your machine before proceeding. The final step for preparing to use the Dell software for calibration is to disable User Account Control (UAC) in Windows.
You'll need to be an administrator to do this. It can be found in the Users section of your control panel. In Windows 10, simply slide the selection down to 'never notify'. This will stop all of those messages that prompt you to give permission when you're installing new software. This is essential, as the Dell software will fail calibration if it is interrupted.
Step 2: Preparing the Monitor As with all hardware, it is usually prudent to keep the associated software up to date. Be sure you have the latest drivers for the monitor installed. They can be found on Dell's website or through Windows Update. Also ensure that the upstream USB cable that came with the monitor is connected directly to a USB port on the computer.
Do not connect this through a USB hub, as calibration may fail if you do. The next step is to use the monitor's factory reset to bring it back to its basic settings.
Using the monitor's menu, navigate to Menu, Other Settings, Factory Reset. As something you have set in the menu may affect the accuracy of the calibration, this is required before continuing. Dell's monitors come with several factory default calibrations such as AdobeRGB and sRGB. These cannot be overwritten, so we will need to select a custom calibration to write to.
Again, using the buttons on your monitor, select Menu, Color Settings, Preset Modes, Color Space, CAL1. You can also select CAL2 for a second calibration after your first is complete, allowing you to have, for example, an AdobeRGB calibration and an sRGB calibration. This may be useful for some applications such as web browsing, where AdobeRGB colour space. Step 3: Installing Dell's Software The only application that can write the hardware LUTs required to accurately calibrate these monitors is. After running the installation, connect your i1 Display Pro to the USB port on the back of your monitor.
Step 4: Calibration If you have completed all the steps above successfully, you should simply be able to have a cup of coffee while the i1 Display Pro does its job. So, put the kettle on and open the software. The first screen you will see is Display Settings. If you have multiple monitors, select your Dell monitor here. From the drop-down lists, select your RGB primary. For me, I have set CAL1 to AdobeRGB for photo editing. You can allow the i1 Display Pro to measure the ambient light in your room and set the luminance accordingly, or you can choose a custom luminance.
In my room, the i1 measured the appropriate luminance to be 100 cd/m^2. If you plan to set it manually, remember that between 80 and 120 cd/m2 is usually appropriate.
Definition Of Calibration
Anything brighter and you may strain your eyes quite a bit. The next screen will be Measurement. If everything has gone well, you will see your i1 Display Pro listed and a color swatch on the right-hand side of the screen. From the drop-down list, select the name of the calibration you are going to overwrite — in this case, CAL1 (calibration 1 in the software). Click 'Start Measurement,' place your i1 Display Pro as instructed, and get that cup of coffee. Once it's all done, the LUT will be saved for you and an ICC Profile will be created for Windows to use. Save this, and enjoy the best your monitor has to offer.
Thank you for the write up on this as I have essentially the same set up on my PC with a Dell U3014 monitor. I did the 30-bit thing with a Quadro card and such which made a subtle but noticeable difference but haven't taken the time to pick up an i1 Display Pro to do the hardware LUT calibration. How noticeable is the difference between it and just using the Spyder 4? I haven't had any issues with my prints matching the screen using the Spyder, but I'm always looking to get the best out of my gear. I bought new Dell UP2516D, already having I1 Display Pro: did the right procedure for calibrating CAL1 (adobergb) and CAL2 (RBG).
All working done!! Problem is: by the time this procedure operates on HARDWARE LUT of the monitor, and DO NOT AFFECT software Windows profiles, at the end of this i have the two LUTS of monitor correctly loaded, BUT.Windows profile still resetted at default: so if i open an image with the viewer of Windows the colours are DIFFERENT than same image openend on Photoshop (where i have AdobeRBG default profile set). The questin is: at the end of calibration procedure, it also builds color profile.ICM.Have i to load on Windows?????? Ty on advance.
Talk to a photographer long enough and the question of screen calibration will be brought up. Often many will say it's an incredibly important tool in your post production workflow, and often many more disregard it all together. So what is screen calibration? Is it still a viable issue within photography today, or is it becoming more and more obsolete, like sync cables and light meters? I'm here to explain it to you.
First, I stand on the 'It's exceptionally important' side of the coin. For the first 3 years of my photography career, I was working on an uncalibrated monitor. I wasn't printing my work, so I had really no idea how my photos looked to others.
It wasn't until I finally borrowed a screen calibration system that I learned how important the tool really was. Suddenly all of my photos that I thought were beautiful turned out to be really dark, and really orange in color. There are two main brands of screen calibration software - The and the. While both of these system do virtually the same thing, I've never had experience with the ColorMunki personally. The general use of these systems is to attach them to your monitor, and run a series of diagnostic software.
This will read the output from your monitor based on color and brightness, and adjust them when needed. What you're left with is accurate colors and brightness to insure your prints look just like your monitor output. However, another incredible and important feature among these systems is the ambient light readout. Essentially, these systems also have a sensor built into the front of the unit, and will adjust your monitor's brightness depending on your environment. So whether you're working in a cave-like room like I do, or in front of some ceiling to floor windows with sun shining through, you can be confident that your monitor is accurately displaying brightness and colors.
And color and brightness are the bread and butter to these machines. For the sake of making this simpler, lets instead think of them as white balance and exposure.
With the default settings on your monitor, you're likely over exposed by about 1/2 to a full stop of light. This means your images are going to appear much darker to those with a calibrated monitor, and in print. In terms of your white balance, monitors aim for 6500K, but often miss the mark by up to 200K in each direction for their default settings. So while a photo might look great on your monitor, it could be much cooler or warmer in tone to those with a calibrated monitor. Misconceptions About Calibration Apple Monitors Don't Need Calibrated This simply is not true.
While Apple (and many other brands) do calibrate all of their monitors in factory, this does not mean that stay calibrated, or are calibrated correctly. Most calibration software suggest that you calibrate your monitor(s) every 2-6 weeks to insure that everything is accurate. This is because color temperature and screen brightness will gradually change over time. So while the screen may be calibrated at 6500K white balance upon purchasing, it may be at 6300K after just a few weeks, resulting in incorrect color temperatures. IPS Monitors Don't Need Calibration IPS monitors are exceptional, and most preferred for graphic design and photography. However, they still need color calibration on the regular.
The most important part of an IPS monitor is actually it's viewing angle. Most IPS monitors get their name for the ability to view them at wide angles without any color or contrast shifts, like you might see in an LED or LCD monitor. This just means more accurate color readings, even if you're a little off axis with the monitor. For an exceptional breakdown of monitor types, check out.
With this said, color temperatures and brightness will still shift on IPS monitors over time, so calibration is still very necessary. Calibrate To Your Phone/Tablet Many people foolishly believe that a smartphone or tablet will have correct color temperature readings, and suggest that when in doubt, to calibrate to your phone's screen. However, more often than not, your phone actually has more color inconsistency than the average computer monitor. Aside from that, you're more than likely adjusting the brightness of your phone/tablet screen multiple times during that day, so how will you know what the correct brightness setting is for your monitor? Why Bother Calibrating If I Don't Print/My Clients Don't Calibrate The reason is simple, because it will result in better photos on both your screen, theirs, and look great in print if you choose to do so. The general idea is that all monitors try to get 6500K temperature and about 100 cd/m² (brightness) for their default settings.
However, due to making manufacturing as efficient and cheap as possible, they often miss the mark slightly. So your monitor may be 5300K (cooler color cast), and your clients may be 6750K (warmer color cast). If your monitor is uncalibrated, the photos will look significantly cooler in color temperature to your clients, which may make the photo less appealing. By calibrating your monitor, you're assuring your settings are correct to what the manufacturer is aiming for. When printing, a calibration system is essential, regardless of you are printing at home or through a lab.
Often, calibration system will also supply you with a calibration file that you're able to send with your print order to insure all the colors and brightness will look as accurate as they did on your monitor. Tools such as this insures higher print quality, and less overseeing of the print process (No longer do I have to send my print orders to me to double check before sending them to clients). Truly, there is no alternative to just purchasing a calibration system for your monitor. Web applications might be able to help slightly, but it still doesn't correct any color issues your monitor may be experiencing. For about $100, you can purchase a basic calibration system for your monitor(s) to insure that all of your photos are correctly exposed and toned. However, any sort of calibration is better than no calibration.
If you're curious on where your monitor stands and not interested in buying a calibrator, I recommend you getting a photo of yours printed from a major print lab, without any color corrections done to it. When it arrives, compare it to your monitor's viewing of the image and adjust your monitor to best match the print brightness and color calibration. Certainly this isn't the best method, but it'll get the job done in a pinch. Again, you are mistaking output profiles (what you should be soft proofing) and viewing profiles (the result of calibrating —how your monitor displays the image you are working on no matter what soft proofing profile you choose). Both calibration and soft proofing use color profiles, but soft proofing has nothing to do with calibration (other than it is useless if your monitor isn't calibrated first). The thing to remember is that the image is a set of numbers that is sent from the computer to the video card where the video card translates them into a signal the monitor can read, then the monitor interprets that signal into lights for your eyes.
Once you calibrate your monitor, your calibrated monitor profile is already loaded into the video card and makes an adjustment to ALL video data so that what you are seeing is not distorted by an anomaly in the video card or monitor. It is passive for the user— you do not need to do anything because it usually loads on start up.
Essentially, each monitor/video card interprets data and signals slightly differently, and your monitor profile makes adjustments to the data from your computer to monitor so what you see is what the numbers are supposed to show. Soft proofing is so you can see how other devices will interpret the file at the end of editing it, whether that is a a custom profile your lab uses for printing or simply sRGB, which most web software uses to display your photo on another monitor. Soft proofing is just a way to mimic how a different medium will display your photo so that you are not surprised when you get your prints back.
It does this by changing the image data before it goes to the video card. This is where they differ. At it's most basic, soft proofing changes what numbers are sent to the video output device/video card (to mimic another medium) then those numbers are adjusted by the video card (using your calibrated profile) to compensate for monitor inaccuracies. If you soft proof with your monitor profile, the image is adjusted as it is output to the video card and again at the video card.
You have adjusted it twice and made it less accurate for no reason. I'm not trying to be an ass about this, but this is a very complicated subject, and you are giving out wrong information that will only make it more confusing. 95% of photographers only need the information in this article and a basic knowledge of Photoshop to be able to color correct their own images.
Your justification that calibration is easy, and that it's 1100 words of free content are hardly reasoning to prove Fabien is wrong. What does free have to do with anything?
Nobody is arguing the free part, they're arguing your click-bait title. In your heart of hearts, would you call this an 'Ultimate Screen Calibration Guide'?
I'd like to know if you genuinely would consider this an ultimate guide. If you were looking for information about calibration, a title like that would suggest that this is THE guide. A one stop shop, if you will. You basically just outline some basics of why we need to calibrate.
To get defensive on this when the vast majority of commenters on here (many who seem to have at least a decent grasp on the subject) disagree with you comes across as just plain petulant. If you are right, then back it up with reasoned arguments, or just stay silent.
As the poster, you're held to a higher comment standard than anybody else because you're supposed to be the wise teacher, and we're the students. I would buy into a bit of this information had I not started about 7 years back with a profiled workflow, using XRite's products and suffering through really poor upgrade, support and issues with their products. Maybe the company has changed in the last 4 or 5 years. I don't care at this point. You only get one kick at the can with me when I'm spending upwards of $300.00 on a flow component and then offer the type and style of support I recieved I'll wing it and detail out any instructions to the lab as to whether correct, or not to correct an image sent in. This company is dead to me. The X-rite i1 Display Pro is better than either the ColorMunki Display or the Datacolorversion Spyder 4, especially if you use multiple displays.
And if you douse multiple displays each needs its own video processor otherwise you end up apply othe profile for one display to the others aswell. Even if the displays are make & model identical the reality is, they are not. Each display is a unique instrument. I suggest that Mr. Sutton start by reading Andrew Rodney's book 'Color Management for Photographers' if he wants to write about the subject of calibration and profiling displays before he writes about the subject again. And yes there are two steps to the process although ever you decent and high quality display profiling software has long treated it as a single process.
The first step, Calibration, is where you set the parameters you want the video system (graphics guard and display) to try and match, and profiling is what the colorimeter is used for. A series of known values for colors are sent through the video pipeline, the colorimeter sees what appears on the screen, and that value is compared to the original values and for each color if necessary a value is added to the signal to correct for the error. As long as each display has it's own port (ie. You are not using a splitter between the computer and the monitors), you can assign a profile to each. I can't tell you exactly how to do it because each machine and calibration software works slightly differently, but with the spyder software on Windows, you can switch off the second monitor (the one you are not calibrating) in the graphics properties. Then, once calibrate the monitor, you can either assign the profile to the monitor in that same dialog or in the colorvision start up dialog.
Just make sure you give each profile a different name (ie. Eminem straight from the vault zip. LeftMonitor or RightMonitor). That is how I have my machine running two monitors. Actually, from my understanding, the ColorMunki and i1 are the same hardware, but the software is what is actually different. However, for calibrating an HDTV you can use a free, open source software available on AVS Forum called HCFR. It is very highly regarded, but requires you read the in depth tutorials so you can dial in all of your advanced picture settings.
The software included with the X-rite's will be more user friendly though, but the point is you can use HCFR with a ColorMunki and achieve identical results if you know what you are doing, and want to save some cash too. Yes I would like to agree on this although I am a great fan of your site (fstoppers) I do really agree that this is not a guide at all. I work as a part time teacher in both post and the technical aspects of digital photography and a part of that is color management and I am afraid that you are not in any way clarifying the subject. The subject then gets more confused by other posters addressing issues they feel is missing.
It is important to get the concept of what is what as to 1. 'input' profiles i.e. Camera, scanner profiles 2. Display profiles i.e. Screen, monitor or projector and then 3. The output profile i.e.
Printer profiles (CMYK) or in that case using srgb for web display. This in turn needs to be separated from 'work' profiles such as Adobe RGB, ColorMatch RGB, srgb or ProPhoto RGB in the sense as they allow the gamut ( which basically means the amounts of colour information and its relationships to each other that is contained in your RGB file) of you digital image file. Is it very good that you are attempting to make it easier to understand but you also have to explain the difference between calibration and the profiling of the monitor and the importance of using standardised calibration settings and the create the profile on those calibration settings. If anyone wants to know my recommendation it has always been the use a L-gamma if available in the software ( in the two above this is an option but has to be selected as it is not a default setting) native white point unless you can afford the top of the range screens (2000$ plus) and 120 candela unless you are working i print specific workflow where a setting of 100-110 candela might be better.
I am aware not everyone will agree with me but this is basically my setting developed for the biggest common user base and to avoid as many pitfalls as possible. You can then create the profile specific for you screen and any crap screen with a correct profile is way better then the best EIZO without a profile.
I dont agree that you will have to read Rodney´s book before you have a go at this but it sure would help since it is one of the better books to get a good start in understanding in what colour management is all about and then if you want you can go crazy and get really nerdy about the subject. I am in no way trying to disrespectful about what you are doing but this is a very complicated subject and is very difficult to simplify mainly because the application of this is not fully matured and there is a ton of misconceptions about how to work it to your advantage and for a control of you output. I would be happy to continue this but now I have to prepare for tomorrows teaching;-).
