Simon, there are more than one setting in PS that determine the "policies" PS is using when opening existing files or creating new ones, so much so, that we'd all get hopelessly confused trying to list all the options.
I
am confused. Where are all these other options other than in the Color Settings dialogue ?
I find that the best way to gather a little piece of mind is to go to the dialogue box at the very lower bottom of the image window and set it to always show the document profile.
I have this set as default. Have for a very long time.
The null transform trick does, however, as Doug correctly pointed out, tell PS to leave the image alone and perform no further conversion. I guess it is fair to say a specific part of the PS color managed environment does get "turned off" when source and destination space both have been assigned the same profile…
This is interesting, as it was well documented some years back that the null transform method stopped working on the Mac after a update to the OS or PS (not sure which now). I confirmed this for myself and so stopped using it, substituting ACPU to print targets instead. Doug and you seem to be saying this is working again. Can one, or both of you, confirm whether this has been tested on a Mac ? And, if so, which version of OS and Photoshop it you have confirmed this with ? Thank you.
