Thanks everyone, this was super helpful.
So if I turn down the brightness to its lowest setting, it actually appears to mimic the prints very well, though I do lose some of the colour accuracy I have at max brightness. That will work great for soft proofing. Is there a good way to store 'exposure for print' settings for export without just changing an images exposure? In Lightroom, I suppose I can store a virtual copy of an image 'ready for printing'. Is there a good way to do something similar in Bridge/Photoshop?
