I use Smart Previews to work on photos when I am away from home, so I don't have to carry my external drive with me. I am about to purchase a ColorMunki for screen calibration. Since I will be working on Smart Previews when I calibrate, is this a problem when I go to print/share the actual photo? Thanks.
It shouldn't be a problem because in order for you to print it will be necessary to have access to the master photo. That means that all the adjustments that were made to the Smart preview will be applied to the master image and there shouldn't be any variation between the two.
