Well, I have been obsessed with getting colour correct for a while now and the biggest problem has always been that when I produce an image, edit it in post production, finally get it how I like it and publish it, When I look at said image it always looks different on my laptop, net-book and the missus's laptop. Across the other computers, the pictures although different, are all a lot brighter with less contrast. The thing is, It will look different on other peoples computers too. Even printed pictures are never the same as on the computer !!
Its time to have done with it and get some proper colour calibration going on my monitor.
I originally was going to get a Spyder 3 pro, but was always a little put off by the price. I needed the pro version because on my computer set up I use multiple monitors. Because I am going to (soon) switch to a new (single) monitor, I wouldn't have needed the pro version.
I came across the Huey Pantone system a while back, its price point was not too bad, but again needed the pro version for multiple monitors. I then spotted one on ebay, boxed, as new and only had one bid of £10... I eventually got it for £22.55. It was only up the road from us in Morecambe, so I went to pick it up. I wasn't bothered that is was not the pro version, the price I got it for and the cost of a upgrade from pantone to the pro version was still a bargain.
It didn't take long for me to calibrate my monitors at all. and what a massive difference it has made.
I would advise anyone who is looking at photography in any sort of serious way to get some sort of calibration system in place. Even a cheap system is better than none at all.
