I already wrote about my my printing experience and other purchases connected to it, but I omitted to review another purchase I made relating to it, Spyder2 Express printing calibration hardware/software. So I will mention it and tell you about my experience.
Any Photoshop or digital photography book you will buy today will talk about monitor and printer calibration and how you should really never attempt your own printing without it. Why is that? I found out very quickly as I made first few prints last winter. I had an image of the glass building in the winter (here is the link) and I knew I wanted the colors of snow and the skies to be in print what they are on the monitor. To my surprise, the colors of snow were blue and I was rather disappointed with the print. So it's simple - calibration of your monitor/printer ensures that the colors you see on your screen are the colors you will see in print. There are subjects where deviation in color will not seem significant (such as shots of nature or black & white images), but whenever you have subjects where you need to get your colors right (such as skin tones, or white snow), you need to have calibrated monitor.
There is software that comes with Photoshop (Adobe Gamma) that can help you calibrate the monitor if you have PC, and Macs actually come with calibration software as well, but I found both options to be somewhat inaccurate, as you are really guessing with your eyes and your choices depend largely on luck. I wanted to have more accurate results, so I decided to invest into hardware calibrator that will do all the work for me.
After some research, I decided not to spend too much money, and buy Colorvision Spyder2 Express that costs less than $100 and comes with both the software and a piece of hardware that you attach to your monitor that does all the work of reading color information for you. The software was easy and simple to install without reading the manual, and all I had to do was attach the calibrator to the screen and come back 10 minutes later. New iMacs actually come with screens that have rather dull default colors, but calibrator was able to fix that, and now I enjoy more dynamic range in my colors. The whites are whites as well (I had no idea I had a yellow overcast before). Following calibration, I calibrated my wife's laptop and it was nice to see that now colors of images look identical on both screens. I also made prints of both colorful nature images and colorful portraits (I used inkjet printer and Cotsco lab with their custom profiles) for my tests and the prints came out with the colors I intended.
It's a great solution if you're printing from your computer. This version of calibrator will not give you more than one option of how your screen will look when calibrated, but default options are good enough, and if I want to have more choices, I only need to upgrade the software, as hardware is compatible with more expensive versions. I now calibrate regularly, and I don't have to worry about the color when I get prints in my hand.
