What is the best way to calibrate my monitor without hardware add-ons (and preferably free)?
Some More Info:
From what I have read what seems like the best way to calibrate my monitor is using a piece of hardware like a Spyder or something similar. Yet currently while it is on my list to buy it will not be an immediate purchase.
So it comes down to this, what is the best way to calibrate a monitor using software/my eyes. Also I understand this is not the best, however, my theory is that this is better than nothing at all.
