I'm back, unfortunately that fix ended up not really being a fix unfortunately. If I use it I have to choose to either turn off the calibrated profile on my monitor and loose the calibration on that (not happening) or on my laptop (which I hate, I'm having to toggle back and forth depending on whether I'm editing or not). I've also noticed that ACR is still not quite the same as photoshop and that the problem extends to web browsers as well, I mainly use Chrome but have been using Firefox for the course and the problem is on both. I'm at a loss about what to do and I don't know where to start looking. At the moment I either have to put up with the inconvenience of changing the laptop monitor profile every time I want to edit and the slight difference in ACR or use Lightroom (which I know you don't recommend) and put up with the web browser porblem. Do you have any suggestions or ideas?
