Hi,
I'm trying to batch edit in ACR and my photos keep looking like this. My camera raw is usually a much lighter grey, as well, so it almost looks like the whole thing has gone to a "negative" look. I tried to open up one at a time, and they still look like this. I tried searching the Facebook page and this site, but I'm not sure exactly what search words are right. None of the ones I'm using, anyway.
If it's something really obvious, you'll have to excuse me. I'm pretty sick right now and not really thinking well.
