Review Spyder 4 Express
Monitor calibration and profiling from Datacolor
The Spyder4Express from Datacolor is the latest in a line of monitor calibrators that we’ve looked at over the years.
In this review, Keith looks at how new Spyder4Express package works, and why you would want one.

For many users, this package represents the best value approach to the vital step of calibrating your monitor.
The examples shown are using Apple Macs, but the software generally works in the same way on Windows PC machines.
You can even improve your TV display setup with the Spyder4TV/HD

Monitor Profiling – Why?
If you’re happy with why calibration is a good idea, you can jump to the main review.
Look around you, look at the colours on your screen and the surroundings.
Notice the subtlety in colour and brightness, and how the lighting changes the look of objects.
If you are editing photos, then all this variety needs to be accurately displayed on your screen.
This screen is actually emitting light of just three colours.
Red, Green and Blue
Look very closely and you’ll see the individual dots of colour.
The photo was taken of my screen, with a close-up macro lens. It’s my eye, from a smaller version of the B&W picture on the ‘about Keith‘ page on this site.
How green is the green you are seeing – how green is the green I’m seeing on the screen I’m using?
Is it a more intense (saturated) green than mine or is it even quite the same colour green (hue)?
So, I’ve no way of knowing what are the precise range of colours that can be represented on my screen or yours.
Problems with white
I often get asked for suggestions about learning more about the nuts and bolts of Colour Management.
My usual suggestion is Bruce Fraser's Real World Colour Management. My own copy is well thumbed. It's my first port of call if I'm asked a question and I feel I don't quite understand an issue well enough to be absolutely sure of an answer.

Look a the white of this page. Look around for objects that you know are white.
If you are indoors, then how a piece of ‘white’ paper looks, depends on the lighting you have. If you’ve different lighting in different parts of your house (such as fluorescent) then take a white object round with you and see if it still looks white. Try outside in daylight.
A white object is white because of the source of light that illuminates it has a certain mix of colours, which are reflected from it.
This mix can vary quite a bit – think of the difference between candle light and the light I see coming in through a north facing window at noon on a sunny day.
Such variation in light sources can be measured and gives what is known as the ‘colour temperature’ of the light source. You may have come across this if you’ve set the white balance for your camera.
In almost every instance though, the white object still looks white to you – our visual system has a pretty good ‘Auto white balance’ function.
Our visual system is incredibly flexible in the way that different types of light are interpreted. In many ways, it’s this adaptability that allows us to happily use rather poorly adjusted monitors, without noticing any problems.
The image of my eye is a black and white one (you’d need to stand quite a distance away to see).
White (or grey) on a screen is produced by producing equal amounts of red, green and blue from each triplet of coloured patches (3 of which make up each ‘pixel’ on your screen).
Pixels are given numerical values to reflect this mix of three different colours, often called RGB values, where the three numbers might typically take a value from 0 to 255.
[0,0,0] is no light of any colour – or black, whilst [255,255,255] represents white (R=255, G=255, B=255).
The problem is that as we saw earlier, I don’t know exactly what each colour really is, for my screen, or yours.
Just because the computer sends ‘white’ to the screen, doesn’t tell us the actual colour of the light that the screen emits.
So, I’ve no way of knowing whether the white on my screen has a colour cast, or what sort of white (colour temperature) it best matches.
What’s in the shadows?
If I look at a photo on my monitor with details in the shadows, then how do I know that my monitor isn’t making the shadows too dark, or too bright?
For a black and white print, such as the forest scene to the right, the whole impact of the print relies of the contrast between different areas.
If I can’t trust my monitor to display the contrast correctly, then what happens if I send the image to someone else to print?
What happens when I try and print the image myself?
If the monitor lightens shadows, then I’ll be tempted to darken them when editing.
If I send this lightened image to be printed, then there is every chance that the shadows that looked fine to me on my monitor will come out too dark when printed.
So. I’ve no way of knowing if my screen is correctly representing bright and dark areas of an image.
Fixing the problems
Modern displays are a lot more consistent in their output, than in the past. That said, there is considerable variation between models and makes in their range of colours and screen brightnesses.
I hope that some of the examples I’ve pointed out, illustrate why just trusting to your eyesight is not the best way of adjusting your monitor.
Our eyes really don’t work well as precise quantitative light measuring devices – that’s not something of day to day use for us (or any animal with eyes).
Fortunately, precise measurement devices are available, to measure (profile) the characteristics of our screen and calibrate our computer’s display system to known standards.
As you’d expect, there are a lot of technical details about colour, light measurement and our visual system that I’ve skipped over here.
The good news is that you really don’t need to know any of this sort of stuff to benefit from calibrating your monitor.
With a device such as the Spyder4Express, the emphasis is on getting the basic job done. If you have multiple monitors or a projector you want to calibrate, then you’ll need one of the more advanced options, such as the Spyder4Elite.
There are lots more articles I’ve written, which go into more detail about printing and colour management.
- Why don’t my prints match my screen? – A short article showing why there is more to getting your prints to match your screen, than just calibrating your monitor.
- Why are my prints too dark – some basic suggestions to this common problem.
If you’ve an older Spyder calibrator, then the main difference with the new package is in the sensor. This from Datacolor:
- Full-spectrum colour sensor – Spyder4Express’s patented 7-colour sensor improves upon colorimeters that use 3-channel RGB sensors. Each Spyder4Express unit is individually tuned in the factory to accurately handle a variety of wide-gamut and normal gamut displays with ease.
- Improved accuracy and stability – The fourth-generation Spyder4Express has double-shielded colour filters for an even closer match to CIE colour standards and improved long term stability. Average accuracy increased by 26% and consistency between Spyder units has improved 19%
I’ll run through the basics of using the software here, with the emphasis on how simple the process is.
The Spyder4Elite review contains a lot more technical information, covering the more advanced features of that package
The device is supplied in a display pack and includes
- Datacolor Spyder4Express colorimeter
- Spyder4Express Software CD
- Quick Start Guide (in 10 languages)
- 1 year warranty (for countries of the EU, the period is 2 years)
- Free On-line Support
A counterweight slides along the USB lead and should be moved to hang behind your monitor when measuring.
The sensor has soft pads on it, so should not mark any screens.
The light sensitive part is behind the honeycomb aperture window and consists of a number of different filters, a diffuser, lens and seven different photo sensors.
The internal measuring components of the Spyder4Express are the same as used in the more advanced Spyder4Pro and Spyder4Elite models.
When calibrating LCD screens, I try and tilt them backwards a bit, so as to get a good contact between sensor and screen.
Installation of the software
A CD is supplied for software installation, along with a printed quick-start guide.
One very nice feature is that the installer checks for updates -before- installing the software.
After installation you will need to authenticate your installation. This gives a code that you can use to install the software on other computers and use it with your particular Spyder 4 sensor.
The software is very simple and guides you through the steps needed to calibrate your monitor.
On your first startup, there are a few reminders.
Note the question mark beside the display controls item.
Datacolor’s Spyder software has always had extremely well thought out help information.
It’s well written and answers most of the essential ‘Why am I doing this?’ type questions that you may have, particularly if this is your first use of a proper calibrator.
Note the items about lighting and screen brightness – don’t set your monitor too bright.
You need to tell the software what type of screen you are using.
The software will identify most display types, but if it’s not sure, it will ask you for more information about your display.
I’ll show some examples, calibrating my MacBook Pro, which has an LED backlit screen (the software knew this)
Move you mouse over the image to see the placement.
The screen will go through a range of colours, whilst the sensor measures the light that comes from it.
It’s the difference between what the software is telling the screen to do, and what is measured, that allows the software to build up the calibration and profiling settings required for your particular screen. This information (profile) is then used by other software to ensure a more accurate display.
The blue light on the device flashes every so often during the measurement process.
After a few minutes, the process is complete.
Once calibrated, you can view the Datacolor test image(s), to see how your monitor looks.
This gives a good feel for the change, but remember that if you were using the unprofiled setting, your eyes would quickly adapt to what you can see here as a distinct blue tinge.
You new profile is now saved in the default location for your computer.
That’s it – your display should now display colours and brightness levels much more accurately.
Important Note – it’s quite common for the calibrated screen to initially look worse than before. This is an illusion. Go away, have a cup of coffee or whatever, and come back. The screen should look much better.
The Spyder Utility
A small program is run at your computer’s startup, which provides ongoing profile quality checking, and can be used to directly launch the Spyder4Elite software.
It offers a number of different settings, including the calibration reminders.
One use for this calibration checking software is that it can spot if some other software (or person) has altered your colour management settings (more likely on Windows PC systems).
There are also the main program preferences, which you’ll likely not need to touch.
Two exceptions are if you want to set the colour temperature of your display to its native setting (better for some old laptops) or want to enable the additional controls for controlling the software on a tablet or netbook.
The additional controls allow for adjustment using a small netbook screen.
Note in the screen shot above (not from my laptop) that monitor type (bottom RH window) has been set to match the type of monitor I’m using. Normally you won’t have to bother with setting this.
Once finished, the software also has the ability to compare the monitor gamuts of your profile, to various standards.
I can see here that my MacBook Pro manages some 97% of the sRGB gamut.
If you look carefully, you can see that my laptop with its LED backlit screen, actually manages quite a bit more (red triangle) in the red/orange/yellow part of the spectrum.
Just a reminder to treat any gamut size number with due care…
If you are wondering why this screen is there?
Well… it looks good (it does have more uses in the more advanced Spyder packages, but that’s genuinely not important for most people)
Buying a Spyder4express
We make a specific point of not selling hardware, but if you found the review of help please consider buying the Spyder, or any other items at all, via our links with Amazon or B&H

It won’t cost any more (nor less we’re afraid) but will contribute towards the running costs of our site.
If you are concerned with the quality of your pictures that you are editing (and printing) then you need to calibrate your monitor – the Spyder4Express does just this, simply and effectively.
The new sensor and refinements to the profiling algorithms make Spyder4 profiles both more accurate and consistent compared to earlier versions. LED backlighting and wide gamut displays are handled without problems.
I’d suggest that the Spyder4Express is all that’s needed by the majority of people wanting to profile their monitor for a better looking display.
If you want to set arbitrary whitepoints, luminance levels and contrast ratios, then you’ll also need one of the other Spyders, but let’s be serious – most people don’t need this.
The Spyder4Express sets your monitor to the fairly universal gamma of 2.2 and a colour temperature of 6500K (if this is of no interest, take it as another sign that the Spyder4Express meets your needs and ‘just works’)
One thing I’d note, is that modern screens are often extremely bright. This has the effect of opening up shadows in images (making them appear brighter) These images, when adjusted to look ‘correct’, will often print too dark. If this is a problem, then turn down your screen brightness a bit more, before profiling again. My Apple monitor is set at about 40% brightness, although this means that I end up working in a more dimly lit room (your screen should be the brightest part of your workspace)
If you’ve multiple screens (Spyder4Pro & Elite) or want to profile a projector (Spyder4Elite), then you’ll also need one of the more advanced Spyder4 options. In our Spyder4Elite review, I’ve included far more details about the functionality and processes, but the thing to remember is that if you just have one screen where you edit your pictures to be printed yourself or by someone else, then for the majority of people, the Spyder4Express does all you need.
Monitor calibrator that does just what’s needed for the majority of users.

Comparing the Spyder 3
Before calibrating your monitor on Windows PC systems, you should check to see that Adobe gamma is turned off if it was installed. We’ve got a short guide to removing Adobe Gamma that might be of help.
