Is the thumbnail preview of the RAW in Bridge the same as the one in PS or the same as the one in ACR?
Now that I've reset ACR defaults, all three images look the same. (Which is wonderful!) So, I can't say with 100% certainty, but the way I remember it, Bridge previews and ACR looked very much alike. It was only when I opened something in Photoshop that I wondered what the heck had happened. I had quit trying to edit anything in ACR at all. Everything looked different before opening in Photoshop, itself.
I tried making some awful adjustments to some RAW files, and do see that edits DO stay with a file, even if 'default' and 'as shot' are clicked later. It's great to know that to really get back to the original, the right click>Develop Settings>clear will truly return the file to default. However, FWIW, I also noticed the circle with 2 lines and triangles appear beside a Bridge thumbnail every time I open a file via ACR, even if no adjustments are made in ACR.
Again, thanks to all - I've just made a pretty true print, now that I've figured out how to add my printer paper profile to the Photoshop >View> Proof Setup dropdown - and soft proof and soft proof - print the image. At this point, I don't know how I managed to consistently get such good color printing results all these years - before the wide gamut monitor. Just lucky until now, I guess, but I'm finally getting some results that are reasonable, though not perfect. It's better than having to face the decision about throwing this laptop out the window... or simply jumping, myself!
thanks again, everyone,
Paz
