So what? It's how Bridge renders its images, it's an integral and essential part of Bridge, always has been.
No, Bridge doesn't render the image, ACR, a plug-in does. Bridge just points to the file and calls up a totally different 'application'.
Well duh! Judging this post and the others, you simply do not grok the paradigm used by LR/ACR/Bridge.
Oh, I get it. If only I could share with you, conversations I and others (guys like Bruce Fraser)made as alpha testers to Adobe about this, when you didn't have a clue CS3 even existed! I'm talking November of 05 buddy.
And then you have the audacity to moan about the tool working oddly.
Yup, and I'm not alone.
Do you also whinge about how you cannot see the hidden layers in PSD files when looking at them in say Word or Safari?
Is whinge a word?
No, I'm not talking about Word or Safari. And I didn't say anything about hidden layers. Open a JPEG in any application other than ACR or LR after making adjustments there and tell me what the preview looks like. They don't match, not even close.
As you missed the point above, treating Jpegs in ACR is an option
No really? Thanks for pointing that out to me. You're a weight of information and a pleasure to communicate with (Was my obvious sarcasm, a bit too subtle for you?)
The point isn't there's an option or that we shouldn’t be able to handle JPEGs like raws with metadata edits. The point is, the current implementation is super sloppy.
We haven't even discussed what a poor engine ACR is for handling this kind of work considering it's doing all processing in a linear gamma very wide gamut space and has to convert all gamma corrected JPEGs and Tiffs to this tone response curve then back to simply apply the edits. A good deal of JPEGs are going to fall apart in a bad way using this process. ACR's engine was designed for linear encoded high bit raw data. If you don't know the vast differences between that and a rendered gamma corrected JPEG, we need to start a new thread and start the education process.
JPEG and rendered metadata editing is useful. Doing it in ACR, even if you fixed this kludge of a workflow and user options is still a very bad idea. Its as Bruce said, a clever hack.
