Is that the case with ALL your photos, or only these few troublesome ones?

Yes. Can you change that setting to "High Quality on Demand", then go to the Tools menu and purge the cache for that folder again. When you do that, all the raw files should look unedited. Then, when you click on a file, it should appear in the Preview panel briefly looking unedited, then it should change to look edited. I want to know if it does that, and if the change looks like the change you see in ACR.

I have to go out also. We'll continue later.

Well, 2 seconds is MUCH better than the 5-10 seconds that you reported earlier, so I'm very pleased about that. That small delay then change in ACR is very normal (although 2 seconds is still a bit longer than average). I'm not concerned about ACR. Everything points to Bridge not being set to "Always High Quality", but you assured me that it is.

Ok, let's forget about the jpegs for now. (We'll come back to them later, because they're important, but not in the way you think). If we boil this problem down to its bones, it's that raw files don't match between Bridge and ACR, yes?

Yeah, I fear so. Just to check - do you only have one screen? Not a dual-screen setup?

No, you did right. Although maybe we should have purged the entire cache too I can't figure out why you think it would have wiped out your workspace, even though you didn't check that box?

Did you get these three options?

Ok, good. In that case, I think we need to go to the (almost) nuclear option. You'll need to reset Bridge's preferences. http://planetphotoshop.com/resetting-bridges-preferences.html

This I need to see. Please open the raw file into ACR, and take a screenshot of it there. Then open one of the jpegs into PS (NOT via ACR, this is crucial) and take a screenshot of it there. Then post both screenshots for me.

But they do match ACR?

When you save a jpeg, are you doing it directly from ACR using the "Save as" button, or are you opening the file into Photoshop and saving there?

I also can't remember what you said - does ACR match the raw file, or the jpeg?

I think I forgot to ask - are they native raw files, or dngs?

Ok, now save a new jpeg from the raw file, and see what happens.

Have you raised this with the lab?

Hi Stephanie, can you post a few of the files here?

Yeah, sorry, I should have clarified that. I'm hoping that these changes might help preventing the problem in the future. I'll be interested to hear. However, I didn't expect it to fix the existing problem. So yes, you'll need to purge Bridge's cache. Don't purge the WHOLE cache at once. Just choose a folder in which there are some troublesome files, and purge the cache for that folder, via Bridge's Tools menu.

I know you want it to be something you're clicking. But it's not, sorry. This is simply a matter of not enough computer power. Have you made those changes I suggested yet?

So, can you identify anything you did differently during editing of those ones? A particular preset or anything like that? I have to go out for a bit. Back as soon as I can.

This "changing after ten seconds" problem ... is it happening with raw files you've edited, or not edited, or both?

Gee, now I'm really worried about your computer. That should take one second, not ten.

In Bridge, is this set to "Always High Quality" the way it should be?

Ok, it's time for me to see some screenshots of this. Can you select both files in Bridge so they appear side-by-side in your Preview Panel (make sure you're in "Filmstrip" workspace or similar) then show me a screenshot? Yes, still an issue unless you've taken specific steps to mitigate. In Photoshop, have you gone to Edit>Preferences>Performance, and set additional Scratch Disks? If yours is only set to C drive (by default) that won't be enough. Add another drive as well (one with plenty of space). Also, in Bridge's preferences, I strongly suggest setting up your Cache folder on another drive, not C. And even when you've done all of that, I STRONGLY recommend not having too many other programs open while you're running Photoshop.

Gosh, that's interesting. So even though you said this is happening to apparently random files, it's happening repeatedly to those files when you try the saves multiple times? Gosh, my friend, these specs are a real worry, and could go a long way to explaining the problem. That's such a small hard drive to begin with, and not much free space to allow your software enough working room. I urge you to run Glary Utilities right away.
