So. I've been working in Photoshop extensively for about 6 years now and I am well aware that nothing we do in Photoshop or Lightroom is supposed to overwrite a raw file. I'm not talking about changing it to something a little lighter or darker, I'm talking about replacing a picture of one baseball player with another one - and the original? Gone.
Here's what happened: I have a poster template that contains several layers, 7 of which are smart objects. I change the pictures in the template by right-clicking the smart object layer and selecting "replace smart object," browsing to the new image, selecting, and here is what SHOULD happen: the target picture opens in Adobe camera raw, I make some small edits, click done or okay or something similar, and that new image has replaced the old one in the template. What DID happen was this: I followed the procedure above and selected my target raw file, the picture that was already in the template (the one I was trying to replace with my target file) opened in Adobe camera raw. I thought - Hey, that's wierd! Closed the ACR dialog and tried again. Same thing happened. I opened lightroom and saw - to my HORROR - that the target file had been changed to the same image that was in the template.
If it clarifies: pictures of player A (who played in 2009) is in all of the smart object layers in my template. I want to make that poster be of player B (who played in 2012) so I begin replacing all the smart objects. When I get to the 3rd image in the poster template, Photoshop overwrites my raw file of player B with the smart object photo of Player A. There were no photos of player A on the network drive that the picture of Player B was on. But there's one now. My raw file shows that it was modified about 10 minutes ago.
We tried undoing in Photoshop. That did nothing. We tried deleting the xmp file. That did nothing. We removed it from the lightroom catalog and reimported it. It is now a picture of Player A from 2009 and my picture of Player B from 2012 is just gone.
Anybody have any idea what this could be and how we could avoid it in the future?
