Well, the first step is for me to take a look at one of the "blurry" files, and one of the "good" ones. Please send them to me via https://spaces.hightail.com/uplink/BellePhotography
This is still very very very very very very very very bad. You're darned lucky your computer even starts up properly.
Brian says you should have at least 1/3rd of your C drive free.
You MUST start clearing up space. Don't do any other editing until you have done so. You're in very dangerous territory.
This is better, but still not the 1/3rd that Brian recommends.
Do you literally mean Place?
Hi Ginger, yeah, you only need to calibrate the one you edit on.
It's CRITICALLY important that you set your Displays settings to "Extend" not "Duplicate". Is that how you have it set up?
Please don't worry about this in the meantime. Monitor calibration isn't valid unless you're doing it with prints in hand, so we can't know what's going on. Just chill out and drink wine for a couple of days until the prints arrive.
Did you follow my instructions here?
