Tune your monitor screen for pixel-perfect color accuracy in all situations

Whether you get your photos printed professionally or use your own household printer, it's not unusual to find the prints you produce often look different from how they appeared while you were editing them on your Mac. Colors may shift and appear differently, brightness may increase or decrease, and the problem might get even worse when you send a photo to a friend and discover their computer displays your photo differently again. No matter how you print your photos, getting them wrong time after time is frustrating, time-consuming and expensive, and you multiply the first two by a factor of ten if you need to wait a few days for each batch of shots to be delivered.

An uncalibrated screen can make it hard to spot editing mistakes. Use a calibrator such as a ColorMunki.

The problem lies in the screen you’re using – or, more precisely, how it’s set up. If you use an Apple display, you can feel a little smug: Apple’s monitors, from its Cinema displays to the screens on its MacBook Pros, get consistently good reviews. However, even the best monitor needs to be set up correctly: if it isn’t, you’re creating disharmony between the display you use to edit your images and the equipment you use to print them. By default, many monitors are set up to produce bright, highly saturated images. This makes screens look fanatics in showrooms, but means your photos will appear brighter and more richly colored than they really are – something that only becomes apparent once you’ve spent money on printing them. The way to avoid producing files with inaccurate colors is to calibrate your monitor. Essentially, monitor calibration is the process of bringing the brightness and color settings of your monitor to within certain limits. This ensures that your monitor screen will display a photograph exactly the same as any other calibrated monitor. Calibrating a monitor produces a color profile for your particular monitor that will translate well to the color profile used by photo printers.

Eye of the beholder

Of course, every monitor – and set of eyeballs – is slightly different, but monitor brightness and color aren’t something you measure yourself. Instead, you use a calibrator: a small, photo-sensitive device that measures the colors emitted by your screen while it displays a test pattern. It uses these measured values to correct the brightness and color of your screen. The result? Once you get an image looking right on your screen, it will display correctly on other people’s calibrated monitors; it will print reliably, as well, which means less money wasted on bad prints.

Finding a calibrator isn’t necessarily easy: prices start at about $150 and can become stratospheric for professional models, and it’s sometimes not clear where the benefits in the price increase lie. Often, the benefit of spending more money is better software. For example, Color Munki – whose Display calibrator we’ve used to illustrate this article – includes software called Digital Pouch with some of its calibrators, which allows you to send images with specific color profiles to other people, making sure they’re seeing what you see. It also includes a print simulator called Print Safe, which allows you to see how your images will look under different lighting conditions – a useful way of combatting a phenomenon called metamerism, in which colors appear different depending on the light they’re viewed under.

1.    Half-hour delay

Calibrating a screen that’s just been turned on could lead to inaccuracies. Leave it on for 30 minutes before you start the calibration process.

2.    ColorMunki

This ColorMunki Display calibrator allows you to calibrate multiple monitors attached to the same Mac, for faster system-wide tuning.

3.    Ambient light

Ambient light is an important factor to consider when you’re trying to perfect the color reproduction of your monitor – make sure that no lights in your room are glaring off your screen when you’re calibrating.

4.    Frequent calibration

Calibration shouldn’t be a one-off affair. Recalibrating your display frequently will mean it keeps producing accurate color even as it gets older.

The right tool

Actually using a calibrator is easy. Most calibrators have small rubber suckers on their undersides, allowing them to stick to your monitor’s surface. In most cases, calibration software is designed to be fast and reliable – all you should need to do is load the software, follow the on-screen instructions, and then twiddle your thumbs while your monitor flashes through a series of colors. The only thing to beware of is that the LCD or LED bulbs in a modern monitor can take a while to reach their normal working brightness. For that reason, you should hold off calibrating a monitor until it’s been running for around 30 minutes.

Many screen calibrators work in the background, adjusting your screen’s brightness as ambient light changes.

One thing that effects how fast a monitor’s bulbs reach optimum brightness is age. It’s reasonable to expect a decent monitor to last at least five years, but in that time the amount of brightness it’s capable of emitting will change. This will happen so gradually you won’t notice it – but you leave a monitor’s brightness settings untouched it will get dimmer and dimmer over time, and you might start adding brightness to images unnecessarily. As a result, it’s common practice for professional photographers to re-calibrate their displays around twice a month. You don’t necessarily have to do it that often, but it’s worth bearing in mind if it’s been a while since you’ve opened iPhoto.

Print test

After you’ve calibrated your monitor for the first time, it’s a good idea to get a small print made at your favorite printer as a test run. This way, you can double-check that your changes have been for the better without the expense of messing up a big A3 print.

Ambient light

“Ambient light” refers to the light sources in the same room as your Mac other than your monitor. And, just as ambient light is important when viewing a print, its important when editing photos.

Some take a zero-tolerance approach to ambient light, but while it’s true that editing in a pitch-black room will give you the best results, you don’t need to be a zealot. The most important thing to avoid is direct light hitting your monitor and glaring back at you. This reduces contrast and makes images look more washed-out than they really are. If your room has overhead lighting, consider investing in (or making!) a monitor hood to keep the glare off your screen. If you’re in a room with spotlights, the job is easier: just turn them so they’re not pointing at the monitor. Alternatively, if the room you’re editing in has a dimmer switch, use it to turn down the brightness of the lights before you start editing your shots.

Most calibrators are designed to cancel-out ambient light, but reducing the brightness of your environment will make your monitor easier to use day-to-day. Some, such as the Huey Pro ($99), will measure ambient light every so often and adjust your monitor in response to changing light conditions – useful if the room your Mac is in is naturally lit.
